Full Text Available La representación Hamiltoniana generalizada de sistemas brinda una estructura que puede ser utilizada con ventaja en muchas áreas, entre las cuales se puede mencionar el diseño de observadores y el diagnóstico de fallas basado en modelos. Muchos de los trabajos en estos te mas tienen como punto de partida al sistema en forma Hamiltoniana generalizada y, en general, se omite la explicación de cómo llegar a esta representación, por ejemplo, a partir de un modelo no lineal basado en las ecuaciones de Euler - Lagrange. En este tra bajo se presenta un análisis detallado de cómo es que se obtiene la representación Hamiltoniana generalizada de un sistema a partir de las n ecuaciones diferenciales de segundo orden obtenidas con el formalismo Euler - Lagrange. Con la finalidad de mostrar e n lo particular, después del caso general, cómo se obtiene la representación Hamiltoniana generalizada, se presentan algunos casos de estudio.
Anti-cancer activity of tectona hamiltoniana-an endemic plant of Myanmar

Summary: The ethanolic extracts of barks and leaves of Tectona hamiltoniana (Verbenaceae) were tested for anti-cancer activity against MCF-7 (Human breast cancer) and NCI-H460 (Lung cancer) cell lines employing sulpho rhodamine B (SRB) bioassay. These extracts demonstrated cytotoxicity with GI/sub 50/ values ranging between 24-33 macro g/mL against both cell lines. Upon further fractionation, dichloromethane fraction appeared to be most active against the MCF-7 cell line (GI/sub 50/ value of 3.4+-0.9 macro g/mL) leading to the isolation of lupane type triterpenoids, betulinic acid (1), betulin aldehyde ( 2 ) and betulin (3). Compound 2 and 3, both showed significant cytotoxic effect against both cancerous cell lines (GI/sub 50/ value range 6-11 macro M). (author)
J/ψ and ρ0 meson production at H1

The production of J/ψ and ρ 0 mesons from e-p collisions, both in Deep Inelastic Scattering (DIS) and at Q 2 ∼ 0, has been studied using the H1 detector at HERA. The features of elastic ρ 0 production at Q 2 ∼ 0 are those expected from the Generalized Vector Dominance Model (VDM). However the elastic DIS ρ 0 and DIS J/ψ production as well as the elastic J/ψ production at Q 2 ∼ 0 all show features consistent with models that are inspired by perturbative QCD (pQCD). This pattern indicates that the appearance of a hard scale in vector meson production (either the quark mass, or large Q 2 ) results in a transition from VDM to pQCD. A final topic is the comparison of inelastic J/ψ production to a prediction from the photon-gluon fusion process in NLO. (author)
Signature of an h1 state in the J/ψ→ηh1→ηK⁎0K¯⁎0 decay

The BES data on the J/ψ→ηK ⁎0 K ¯⁎0 reaction show a clear enhancement in the K ⁎0 K ¯⁎0 mass distribution close to the threshold of this channel. Such an enhancement is usually a signature of an L=0 resonance around threshold, which in this case would correspond to an h 1 state with quantum numbers I G (J PC )=0 − (1 +− ). A state around 1800MeV results from the interaction of the K ⁎ K ¯⁎ using the local hidden gauge approach. We show that the peak observed in J/ψ→ηK ⁎0 K ¯⁎0 naturally comes from the creation of this h 1 state with mass and width around 1830MeV and 110MeV, respectively. A second analysis, model independent, corroborates the first result, confirming the relationship of the enhancement in the invariant mass spectrum with the h 1 resonance

Quantum state-to-state dynamics for the quenching process Br((2)P(1/2)) + H(2)(v(i) = 0, 1, j(i) = 0) → Br((2)P(3/2)) + H(2)(v(f), j(f)) has been studied based on two-state model on the recent coupled potential energy surfaces. It was found that the quenching probabilities have some oscillatory structures due to the interference of reflected flux in the Br((2)P(1/2)) + H(2) and Br((2)P(3/2)) + H(2) channels by repulsive potential in the near-resonant electronic-to-vibrational energy transfer process. The final vibrational state resolved integral cross sections were found to be dominated by the quenching process Br((2)P(1/2)) + H(2)(v) → Br((2)P(3/2)) + H(2)(v+1) and the nonadiabatic reaction probabilities for Br((2)P(1/2)) + H(2)(v = 0, 1, j(i) = 0) are quite small, which are consistent with previous theoretical and experimental results. Our calculated total quenching rate constant for Br((2)P(1/2)) + H(2)(v(i) = 0, j(i) = 0) at room temperature is in good agreement with the available experimental data. © 2012 American Institute of Physics

Decays of the form $B^{0}_{(s)}\\rightarrow J/\\psi K_{{\\rm S}}^{0} h^+ h^{\\left(\\prime\\right) -}$ ($h^{(\\prime)} = K, \\pi$) are searched for in proton-proton collision data corresponding to an integrated luminosity of $1.0 \\, {\\rm fb}^{-1}$ recorded with the LHCb detector. The first observation of the $B^{0}_{s}\\rightarrow J/\\psi K_{{\\rm S}}^{0} K^{\\pm} \\pi^{\\mp}$ decay is reported, with significance in excess of 10 standard deviations. The $B^{0}\\rightarrow J/\\psi K_{{\\rm S}}^{0} K^{+} K^{-}$ decay is also observed for the first time. The branching fraction of $B^{0}\\rightarrow J/\\psi K_{{\\rm S}}^{0} \\pi^{+} \\pi^{-}$ is determined, to significantly better precision than previous measurements, using $B^0 \\rightarrow J/\\psi K_{{\\rm S}}^{0}$ as a normalisation channel. Branching fractions and upper limits of the other $B^{0}_{(s)}\\rightarrow J/\\psi K_{{\\rm S}}^{0} h^+ h^{\\left(\\prime\\right) -}$ modes are determined relative to that of the $B^{0}\\rightarrow J/\\psi K_{{\\rm S}}^{0} \\pi^{+} \\pi^{-}$ decay.

Initial state selected dynamics of the Ne + NeH{sup +}(v{sub 0} = 0, j{sub 0} = 0) → NeH{sup +} + Ne reaction is investigated by quantum and statistical quantum mechanical (SQM) methods on the ground electronic state. The three-body ab initio energies on a set of suitably chosen grid points have been computed at CCSD(T)/aug-cc-PVQZ level and analytically fitted. The fitting of the diatomic potentials, computed at the same level of theory, is performed by spline interpolation. A collinear [NeHNe]{sup +} structure lying 0.72 eV below the Ne + NeH{sup +} asymptote is found to be the most stable geometry for this system. Energies of low lying vibrational states have been computed for this stable complex. Reaction probabilities obtained from quantum calculations exhibit dense oscillatory structures, particularly in the low energy region and these get partially washed out in the integral cross section results. SQM predictions are devoid of oscillatory structures and remain close to 0.5 after the rise at the threshold thus giving a crude average description of the quantum probabilities. Statistical cross sections and rate constants are nevertheless in sufficiently good agreement with the quantum results to suggest an important role of a complex-forming dynamics for the title reaction.

The time dependent real wave packet method using the helicity decoupling approximation was used to calculate the cross section evolution with collision energy (excitation function) of the O + +H 2 (v=0,j=0)→OH + +H reaction and its isotopic variants with D 2 and HD, using the best available ab initio analytical potential energy surface. The comparison of the calculated excitation functions with exact quantum results and experimental data showed that the present quantum dynamics approach is a very useful tool for the study of the selected and related systems, in a quite wide collision energy interval (approximately 0.0-1.1 eV), involving a much lower computational cost than the quantum exact methods and without a significant loss of accuracy in the cross sections

We extend previous analyses of the supersymmetric loop correction to the charged Higgs couplings to include the coupling H ± χ ± χ 0 . The analysis completes the previous analyses where similar corrections were computed for H + t-barb (H - tb-bar), and for H + τ - ν-bar τ (H - τ + ν τ ) couplings within the minimal supersymmetric standard model. The effective one loop Lagrangian is then applied to the computation of the charged Higgs decays. The sizes of the supersymmetric loop correction on branching ratios of the charged Higgs H + (H - ) into the decay modes tb-bar (t-barb), τ-barν τ (τν-bar τ ), and χ i + χ j 0 (χ i - χ j 0 )(i=1,2; j=1-4) are investigated and the supersymmetric loop correction is found to be significant, i.e., in the range 20-30 % in significant regions of the parameter space. The loop correction to the decay mode χ 1 ± χ 2 0 is examined in specific detail as this decay mode leads to a trileptonic signal. The effects of CP phases on the branching ratio are also investigated. A brief discussion of the implications of the analysis for colliders is given

The largest TeV source, RX J0852.0-4622 (Vela Jr.), is one of the few supernova remnants (SNRs) with well resolved shell-like morphology at very-high-energy (VHE; E>100 GeV) gamma-rays. Strong non-thermal emission across the electromagnetic spectrum from radio to VHE gamma-rays, young age and proximity of the remnant makes it one of the prime objects for the study of particle acceleration aiming to test the paradigm of SNRs being sources of Galactic cosmic rays. Here we present deep H.E.S.S. observations of RX J0852.0-4622 with roughly doubled exposure comparing to previously published results. Improved statistics together with new analysis techniques result in a firm determination of the cut-off in the gamma-ray spectrum and allow the spatially resolved spectroscopy studies. A smooth connection of the H.E.S.S. spectrum to the spectrum at GeV energies as reported by Fermi/LAT provides an exciting opportunity to recover the present-time parent particle population in both leptonic and hadronic scenarios directly from the gamma-ray data alone. These new observations provide us a deeper insight and better understanding of the physical processes in SNRs.
Precision spectroscopy of the X1Σg+, v=0→1(J=0-2) rovibrational splittings in H2, HD and D2

Accurate experimental values for the vibrational ground tone or fundamental vibrational energy splitting of H2, HD, and D2 are presented. Absolute accuracies of 2×10-4 cm-1 are obtained from Doppler-free laser spectroscopy applied in a collisionless environment. The vibrational splitting frequencies are derived from the combination difference between separate electronic excitations from the X1Σg+, v=0, J and v=1, J vibrational states to a common EF1Σg+, v=0, J state. The present work on rotational quantum states J=1,2 extends the results reported by Dickenson et al. on J=0 [Phys. Rev. Lett. 110 (2013) 193601]. The experimental procedures leading to this high accuracy are discussed in detail. A comparison is made with full ab initio calculations encompassing Born-Oppenheimer energies, adiabatic and non-adiabatic corrections, as well as relativistic corrections and QED-contributions. The present agreement between the experimental results and the calculations provides a stringent test on the application of quantum electrodynamics in molecules. Furthermore, the combined experimental-theoretical uncertainty can be interpreted to provide bounds to new interactions beyond the Standard Model of Physics or fifth forces between hadrons.

Aims: We study γ-ray emission from the shell-type supernova remnant (SNR) RX J0852.0-4622 to better characterize its spectral properties and its distribution over the SNR. Methods: The analysis of an extended High Energy Spectroscopic System (H.E.S.S.) data set at very high energies (E > 100 GeV) permits detailed studies, as well as spatially resolved spectroscopy, of the morphology and spectrum of the whole RX J0852.0-4622 region. The H.E.S.S. data are combined with archival data from other wavebands and interpreted in the framework of leptonic and hadronic models. The joint Fermi-LAT-H.E.S.S. spectrum allows the direct determination of the spectral characteristics of the parent particle population in leptonic and hadronic scenarios using only GeV-TeV data. Results: An updated analysis of the H.E.S.S. data shows that the spectrum of the entire SNR connects smoothly to the high-energy spectrum measured by Fermi-LAT. The increased data set makes it possible to demonstrate that the H.E.S.S. spectrum deviates significantly from a power law and is well described by both a curved power law and a power law with an exponential cutoff at an energy of Ecut = (6.7 ± 1.2stat ± 1.2syst) TeV. The joint Fermi-LAT-H.E.S.S. spectrum allows the unambiguous identification of the spectral shape as a power law with an exponential cutoff. No significant evidence is found for a variation of the spectral parameters across the SNR, suggesting similar conditions of particle acceleration across the remnant. A simple modeling using one particle population to model the SNR emission demonstrates that both leptonic and hadronic emission scenarios remain plausible. It is also shown that at least a part of the shell emission is likely due to the presence of a pulsar wind nebula around PSR J0855-4644. A FITS image of the region of interest and two text files describing the H.E.S.S. spectrum of RX J0852.0-4622 are only available at the CDS via anonymous ftp to http://cdsarc.u-strasbg.fr (http

We have measured the nascent HD(v'=1, j') product rotational distribution from the reaction D+H 2 (v, j) in which the H 2 reagent was either thermal (v=0, j) or prepared in the level (v=1, j=1) by stimulated Raman pumping. Translationally hot D atoms were obtained by uv laser photolysis of DBr or DI. Photolysis of DBr generated D atoms with center-of-mass collision energies (E rel ) of 1.04 and 0.82 eV, which corresponded to the production of ground state Br and spin--orbit-excited Br*, respectively. The E rel values for DI photolysis were 1.38 and 0.92 eV. Quantum-state-specific detection of HD was accomplished via (2+1) resonance-enhanced multiphoton ionization and time-of-flight mass spectrometry. Vibrational excitation of the H 2 reagent results in substantial rotational excitation of the HD(v'=1) product and increases the reaction rate into v'=1 by about a factor of 4. Although the quantum-mechanical calculation of Blais et al. [Chem. Phys. Lett. 166, 11 (1990)] for the D+H 2 (v=1, j=1)→HD(v'=1, j')+H product rotational distribution at E rel =1.02 eV is in qualitative agreement with experiment, it does not quantitatively agree with the measured distribution. Specifically, the calculated distribution is too hot by 2--3 rotational quanta, and the predicted enhancement in the v'=1 rate with reagent vibrational excitation is too large by 67%±9

We investigate methods for filtering reaction mechanisms in the angular scattering of the state-to-state reaction, H + D(2)(v(i) = 0, j(i) = 0, m(i) = 0) --> HD(v(f) = 3, j(f) = 0, m(f) = 0) + D, where v(i), j(i), and m(i) and v(f), j(f), and m(f) are initial and final vibrational, rotational, and helicity quantum numbers, respectively. The input to our filtrations is a new set of accurate quantum scattering matrix elements for total energies in the range 1.52-2.50 eV (in steps of 0.01 eV) and for total angular momentum quantum numbers in the range, 0-40, in steps of unity. We filter reaction mechanisms in both the energy domain and the time domain. The time-domain calculations employ the plane wave packet formulation of time-dependent scattering. The theoretical tools used are nearside-farside (NF) analysis of partial wave series for scattering amplitudes, together with NF local angular momentum (LAM) theory. An energy-domain LAM analysis reveals the existence of an important dynamical feature in the N scattering, a "trench" which bisects the (energy, angle) plane. We use the location of this trench to approximately filter two reaction mechanisms. Transformation to the time domain demonstrates that the two reaction mechanisms correspond to direct and delayed (by about 25 fs) scattering. Further analysis, including filtration in the time domain, shows that the pronounced LAM trench arises from the interference of the energy-domain analogues of the time-direct and time-delayed scattering. Our theory and results provide the first successful demonstration of reaction mechanism filtering carried out directly in the (energy, angle) domain. The calculations and results in this paper extend and complement earlier research reported by Monks, Connor, and Althorpe (Monks, P. D. D.; Connor, J. N. L.; Althorpe, S. C. J. Phys. Chem. A 2006, 110, 741; J. Phys. Chem. A 2007, 111, 10302).

We present two NMR experiments, (3,2)D HNHA and (3,2)D HNHB, for rapid and accurate measurement of 3J(H N-H alpha) and 3J(N-H beta) coupling constants in polypeptides based on the principle of G-matrix Fourier transform NMR spectroscopy and quantitative J-correlation. These experiments, which facilitate fast acquisition of three-dimensional data with high spectral/digital resolution and chemical shift dispersion, will provide renewed opportunities to utilize them for sequence specific resonance assignments, estimation/characterization of secondary structure with/without prior knowledge of resonance assignments, stereospecific assignment of prochiral groups and 3D structure determination, refinement and validation. Taken together, these experiments have a wide range of applications from structural genomics projects to studying structure and folding in polypeptides.

A roadmap to control penguin effects in B_d"0→J/ψK_S"0 and B_s"0→J/ψϕ

Measurements of CP violation in B_d"0→J/ψK_S"0 and B_s"0→J/ψϕ decays play key roles in testing the quark-flavour sector of the Standard Model. The theoretical interpretation of the corresponding observables is limited by uncertainties from doubly Cabibbo-suppressed penguin topologies. With continuously increasing experimental precision, it is mandatory to get a handle on these contributions, which cannot be calculated reliably in QCD. In the case of the measurement of sin 2β from B_d"0→J/ψK_S"0, the U-spin-related decay B_s"0→J/ψK_S"0 offers a tool to control the penguin effects. As the required measurements are not yet available, we use data for decays with similar dynamics and the SU(3) flavour symmetry to constrain the size of the expected penguin corrections. We predict the CP asymmetries of B_s"0→J/ψK_S"0 and present a scenario to fully exploit the physics potential of this decay, emphasising also the determination of hadronic parameters and their comparison with theory. In the case of the benchmark mode B_s"0→J/ψϕ used to determine the B_s"0-B-bar_s"0 mixing phase ϕ_s the penguin effects can be controlled through B_d"0→J/ψρ"0 and B_s"0→J/ψ ( K)-bar "∗"0 decays. The LHCb collaboration has recently presented pioneering results on this topic. We analyse their implications and present a roadmap for controlling the penguin effects.

Crystals of Na [(Fe EDTA){sub 2}o] {center_dot}12H{sub 2}0 were investigated by means of electron paramagnetic resonance spectroscopy. The spectra were obtained at various temperatures and crystals orientations. These spectra are very complex with many absorption bands. As the crystal orientation with respect to the magnetic field was changed the variations of the intensity and number of bands were recorded. The antiferromagnetic coupling between the iron atoms in the bridge Fe - 0 - Fe gives rise to states with total spin quantum number S= 0, 1, 2, 3, 4 and 5. Analyses of the EPR spectra as a function of temperature provided a means for the identification of the EPR absorption bands attributed to the states with S = 2. It was also possible to calculate the exchange parameter value J = 300 K. From the study of bands angular dependence in relation to the crystal orientation in the magnetic field it was found that the magnetic crystal axes X, Y, Z and the crystals axes a, b, c are related as (a, b, c) = (Y, Z, X) {exclamation_point} with a precision of 5 deg. Also the crystalline distortion parameters were calculated D = 0.21 {+-} 0.02 cm{sup 1}; E = 0.015 {+-} 0.005 cm{sup 1}. (author)

The time-dependent $CP$ asymmetry in $B_s^0 \\to J/\\psi K^+K^-$ decays is measured using $pp$ collision data, corresponding to an integrated luminosity of $3.0$fb$^{-1}$, collected with the LHCb detector at centre-of-mass energies of $7$ and $8$TeV. In a sample of 96 000 $B_s^0 \\to J/\\psi K^+K^-$ decays, the $CP$-violating phase $\\phi_s$ is measured, as well as the decay widths $\\Gamma_{L}$ and $\\Gamma_{H}$ of the light and heavy mass eigenstates of the $B_s^0-\\bar{B}_s^0$ system. The values obtained are $\\phi_s = -0.058 \\pm 0.049 \\pm 0.006$ rad, $\\Gamma_s \\equiv (\\Gamma_{L}+\\Gamma_{H})/2 = 0.6603 \\pm 0.0027 \\pm 0.0015$ps$^{-1}$, and$\\Delta\\Gamma_s \\equiv \\Gamma_{L} - \\Gamma_{H} = 0.0805 \\pm 0.0091 \\pm 0.0032$ps$^{-1}$, where the first uncertainty is statistical and the second systematic. These are the most precise single measurements of those quantities to date. A combined analysis with $B_s^{0} \\to J/\\psi \\pi^+\\pi^-$ decays gives $\\phi_s = -0.010 \\pm 0.039 $rad.

A new heteronuclear NMR pulse sequence for the measurement of n J(C,H) coupling constants, the α/βselective HC(C)H-TOCSY, is described. It is shown that the S 3 E element (Meissner et al., 1997a,b) can be used to obtain spin state selective coherence transfer in molecules, in which adjacent CH moieties are labeled with 13 C. Application of the α/β selective HC(C)H-TOCSY to a 10nt RNA tetraloop 5'-CGCUUUUGCG-3', in which the four uridine residues are 13 C labeled in the sugar moiety, allowed measurement of two bond and three bond J(C,H) coupling constants, which provide additional restraints to characterize the sugar ring conformation of RNA in cases of conformational averaging

A preliminary measurement of the ratio of branching ratios BR(B + → J/ψK + )/BR(B 0 → J/ψK 0 ) and BR(B + → J/ψK + )/BR(B + → J/ψK *+ ) is made by fully reconstructing each mode, where J/ψ → μ + μ - , K *+ → K 0 s π + and K 0 s → π + π - . The data were taken with the CDF detector during the 1993 run. The total integrated luminosity is ∼ 20pb -1 resulting in a sample of about 170 J/ψK ± , 50 J/ψK 0 S and 25 J/ψK *± candidate events. The results will be reported
fJ(2220) and hadronic anti Bs0 decays

We study the hadronic anti B s 0 decays based on the existence of the resonant state f J (2220). In particular,we are able to explain the unexpected large experimental result of B(anti B s 0 → J/ψp anti p) = (3.0 -1.1 +1.2 ± 0.52 ± 0.03) x 10 -6 measured recently by the LHCb collaboration due to the resonant contribution in anti B s 0 → J/ψf J (2220) with f J (2220) → p anti p, while it is estimated to be at most of order 10 -9 in terms of the OZI rule without the resonance. In addition, we find that B(anti B s 0 → D *0 (f J →)p anti p) = (4.70 ± 2.89) x 10 -7 , B(anti B s 0 → J/ψ(f J →)ππ) = (15.6 ± 15.2) x 10 -6 , and B(anti B s 0 → D *0 (f J →)ππ) = (24.5 ± 24.4) x 10 -7 , while B(anti B s 0 → J/ψ(f J →)K anti K) < 1.6 x 10 -5 and B(anti B s 0 → D *0 (f J →)K anti K) < 2.5 x 10 -6 . Moreover, we predict that the decay branching ratios of anti B s 0 → (J/ψ, D *0 )Λ anti Λ are (2.68 ± 1.23) x 10 -7 and (2.25 ± 0.80) x 10 -6 . Some of the predicted anti B s 0 decays are accessible to the experiments at the LHCb. (orig.)

The time-dependent CP-violating asymmetry in $B^0_s\\to J/\\psi K^{+}K^{-}$ decays is measured using $1.0^{-1}$ of $pp$ of collisions at $\\sqrt{s}=7$ TeV collected with the LHCb detector. The decay time distribution of $B^0_s\\to J/\\psi K^{+}K^{-}$ is characterized by the decay widths $\\Gamma_{\\mathrm{H}}$ and $\\Gamma_{\\mathrm{L}}$ of the heavy and light mass eigenstates of the $B^0_s - \\bar{B^0_s}$ system and by a CP-violating phase $\\phi_s$.

Measurement of the branching fractions of the $B^0_s\\to J/\\psi\\eta$, $B^0_s\\to J/\\psi\\eta^{\\prime}$ and $B^0\\to J\\psi\\omega$ decays in the LHCb experiment

First evidence of the $B^0\\to J/\\psi\\omega$ decay is found and the $B^0_s\\to J/\\psi\\eta$ and $B^0_s\\to J/\\psi\\eta^{\\prime}$ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 $\\mathrm{fb}^{-1}$ collected by the LHCb experiment in proton-proton collisions at a center-of-mass energy of $\\sqrt{s} = 7$ TeV. Branching fractions of these decays are measured relative to that of the $B^0\\to J/\\psi\\rho^0$ decay. All the channels under study contain photons in the final state. Precise determination of photons energies is essential for accurate measurement of the decays branching fractions. So, an auxiliary task was a regular calibration of the LHCb electromagnetic calorimeter with neutral pions. Values obtained for the $B^0_s\\to J/\\psi\\eta$ and $B^0_s\\to J/\\psi\\eta^{\\prime}$ decays branching fractions, as well as a ratio of these values, are found to be in a good agreement with both theoretical predictions and results of previous measurements. The $B^0\\to J/\\psi\\omega$ decay is seen for...

Non-equivalent methylenic protons, with respect to an asymmetric center, have been observed in the n.m.r. spectra of some three- and tetra-coordinated phosphorus compounds. The analysis of these spectra yield the following results: in the studied secondary phosphines, the inversion rate at the phosphorus atom is slow on the n.m.r. time scale; the geminal coupling constant, for a free-rotating methylene group attached to a phosphorus atom, is negative; in phosphines the non equivalence of methylenic protons reveals two {sup 2}J{sub P-C-H} coupling constants which differ by about 5 Hz. This result is in agreement with previous studies on cyclic phosphines. In phosphine oxides, the {sup 2}J{sub P-C-H} values are negative. The {sup 3}J{sub H-P-C-H} coupling constant is positive in both phosphines and phosphine oxides. In phosphines, the non-equivalent methylenic protons exhibit two nearly equal values for this coupling constant. (author) [French] La non-equivalence de protons methyleniques observee dans quelques composes phosphores tricoordines et tetracoordines a apporte les resultats suivants, concernant la stereochimie et les constantes de couplage dans ces composes: dans les phosphines secondaires, la structure pyramidale des liaisons issues du phosphore est fixe a l'echelle de temps de mesure de la R.M.N.; la constante de couplage {sup 2}J{sub H-C-H}, pour un methylene en libre rotation en {alpha} d'un atome de phosphore, est negative; dans les phosphines etudiees, la non-equivalence. observee pour les protons methyleniques s'accompagne d'une difference importante (5 Hz) entre les deux constantes de couplage {sup 2}J{sub P-C-H} determinees par l'analyse; ce resultat est en accord avec la stereospecificite deja observee pour ce couplage dans les phosphines cycliques. Les valeurs observees pour {sup 2}J{sub P-C-H} dans les oxydes de phosphines sont negatives. Les valeurs de la constante de couplage {sup 3}J{sub H-P-C-H}, dans les phosphines et oxydes de phosphine

We extend to full dimensionality a recently developed wave packet method [M. T. Cvitaš and S. C. Althorpe, J. Phys. Chem. A 113, 4557 (2009)] for computing the state-to-state quantum dynamics of AB + CD → ABC + D reactions and also increase the computational efficiency of the method. This is done by introducing a new set of product coordinates, by applying the Crank-Nicholson approximation to the angular kinetic energy part of the split-operator propagator and by using a symmetry-adapted basis-to-grid transformation to evaluate integrals over the potential energy surface. The newly extended method is tested on the benchmark OH + H(2) → H(2)O + H reaction, where it allows us to obtain accurately converged state-to-state reaction probabilities (on the Wu-Schatz-Fang-Lendvay-Harding potential energy surface) with modest computational effort. These methodological advances will make possible efficient calculations of state-to-state differential cross sections on this system in the near future.
Adsorption of H atoms on cubic Er2O3 (0 0 1) surface: A DFT study

First-principles plane wave calculations based on spin-polarized density functional theory (DFT) and generalized gradient approximation (GGA) have been used to study the adsorption of H atoms on cubic Er 2 O 3 (0 0 1) surface. We identify stable adsorption positions and find that H preferentially adsorbs on top of fourfold-hollow sites and transfers electrons to the surface, resulting in the formations of covalent bonds to the nearest neighboring four oxygen atoms. In the most energetically favorable adsorption sites, It was found that H bonds with O atoms at the cubic Er 2 O 3 (0 0 1) surface with an adsorption energy of −295.68 kJ mol −1 at coverage 1/8 ML, and the adsorption energy is inclined to decrease with the increase of H coverage (>1/4 ML). In addition, our calculations indicate that the dissociative H atom configurations have adsorption energies that are at least 152.64 kJ mol −1 greater than the H 2 molecule configurations on the surface. These results discussed in the context of erbium oxide slabs are employed to rationalize some processes regarding to the hydrogen isotope permeation behavior of tritium permeation barrier
Inclusive J / $\\psi$ Production at D0

We present results on inclusive $J/\\psi$ and b-quark production in $p\\bar{p}$ collisions at $\\sqrt{s}$ = 1.8 TeV. The results are based on data collected at the D0 experiment during the 1992-1993 FermiLab collider run. There is excellent agreement between the differential $J/\\psi$ cross section measured at D0 and that measured at the CDF detector. A measurement of the fraction of $J/\\psi$ events due to b-quark decays is presented and we extract from this a measurement of the integrated b-quark cross section. The radiative decays of $_{Xc}$ charmonium states into the $J/\\psi$ is discussed and we present results on the fraction of $J/\\psi$ mesons that are due to $_{Xc}$ decays. We also observe that a fraction of promptly produced $J/\\psi$ mesons is larger than the measured fraction of $J/\\psi$ due to $_{Xc}$ decays and is not accounted for by existing charmonium. production models.

The time-dependent CP asymmetry in B(s)(0)→J/ψK+K- decays is measured using pp collision data, corresponding to an integrated luminosity of 3.0 fb-1, collected with the LHCb detector at center-of-mass energies of 7 and 8 TeV. In a sample of 96,000 B(s)(0)→J/ψK+K- decays, the CP-violating phase ϕs is measured, as well as the decay widths ΓL and ΓH of the light and heavy mass eigenstates of the B(s)(0)-B[over ¯]s0 system. The values obtained are ϕs=-0.058±0.049±0.006 rad, Γs≡(ΓL+ΓH)/2=0.6603±0.0027±0.0015 ps-1, and ΔΓs≡ΓL-ΓH=0.0805±0.0091±0.0032 ps-1, where the first uncertainty is statistical and the second, systematic. These are the most precise single measurements of those quantities to date. A combined analysis with Bs0→J/ψπ+π- decays gives ϕs=-0.010±0.039 rad. All measurements are in agreement with the standard model predictions. For the first time, the phase ϕs is measured independently for each polarization state of the K+K- system and shows no evidence for polarization dependence.

The Bessel functions J0 and J1 of complex argument

The Bessel function appears in a wide range of physical applications. The package Bessel contains complex function routines to calculate J 0 (z) and J 1 (z) for complex z. Bessel functions of higher order n 0 (z) and J 1 (z) for all values of mod(z) up to machine overflow. For mod(z) 10, the results diverge quite rapidly from their actual values. The accuracy for mod(z)<=10 is sufficient for most physical applications, and the polynomial approximations provide a quicker calculation of Bessel functions than the use of the ascending series formula used previously, particularly for values of mod(z) near 10.

Using data collected with the LHCb detector in proton-proton collisions at a centre-of-mass energy of 7 TeV, the hadronic decay $B^{0}_{s} \\to J/\\psi f_{0}$(980) is observed. This CP eigenstate mode could be used to measure mixing-induced CP violation in the $B^0_s$ system. Using a fit to the $\\pi^+ \\pi^-$ mass spectrum with interfering resonances gives $R_{f_0/\\phi}$ = $[\\Gamma(B^0 _s -> J/\\psi f0, f0 -> \\pi+ \\pi-)]/[\\Gamma(B^0 _s -> J/\\psi \\phi, \\phi -> K+K-)] = 0.252^{+0.046+0.027}_{-0.032-0.033}$, where the uncertainties are statistical and systematic, respectively.

A search for the rare decay of a $B^{0}$ or $B^{0}_{s}$ meson into the final state $J/\\psi\\gamma$ is performed, using data collected by the LHCb experiment in $pp$ collisions at $\\sqrt{s}=7$ and $8$ TeV, corresponding to an integrated luminosity of 3 fb$^{-1}$. The observed number of signal candidates is consistent with a background-only hypothesis. Branching fraction values larger than $1.7\\times 10^{-6}$ for the $B^{0}\\to J/\\psi\\gamma$ decay mode are excluded at 90% confidence level. For the $B^{0}_{s}\\to J/\\psi\\gamma$ decay mode, branching fraction values larger than $7.4\\times 10^{-6}$ are excluded at 90% confidence level; this is the first branching fraction limit for this decay.

At LHCb the B/sub s//sup 0/ to J/ psi phi decay will be used to determine the B/sub s//sup 0/ mixing phase sin phi /sub s/ and the decay width difference Delta Gamma /sub s/, while the B/sup 0/ to J/ psi K/sub S//sup 0/ decay will be used to determine the B/sup 0/ mixing phase sin phi /sub d/. A detailed GEANT Monte-Carlo simulation was performed to study the performance at LHCb for these decay channels. The results were used in a 'toy' MC to estimate the sensitivity for sin phi /sub s/, Delta Gamma /sub s// Gamma /sub s/, and sin phi /sub d/. The precisions that will be reached after one year of LHCb for sin phi /sub s/, Delta Gamma /sub s// Gamma /sub s/, and sin phi /sub d/ are 0.064, 0.018, and 0.022, respectively. (7 refs).

We present a measurement of the time-dependent $CP$-violating asymmetry in $B^{0}_s\\to J/\\psi\\phi$ decays, using data collected with the LHCb detector at the LHC. The decay time distribution of $B^{0}_s\\to J/\\psi\\phi$ is characterized by the decay widths $\\Gamma_{\\mathrm{H}}$ and $\\Gamma_{\\mathrm{L}}$ of the heavy and light mass eigenstates of the $B^{0}_s-\\overline{B}^{0}_s$ system and by a $CP$-violating phase $\\phi_s$. In a sample of about 8500 $B^{0}_s\\to J/\\psi\\phi$ events isolated from $0.37$~fb$^-1$ of $pp$ collisions at $\\sqrt{s}=7$ TeV we measure $\\phi_s \\: = \\: 0.15 \\: \\pm \\: 0.18 \\; \\mathrm{(stat)} \\: \\pm \\: 0.06 \\; \\mathrm{(syst)}$ rad.

Aggregates of conjugated polymers exhibit two classes of fundamental electronic interactions: those occurring within a given chain and those occurring between chains. The impact of such excitonic interactions on the photophysics of polymer films can be understood using concepts of J- and H-aggregation originally developed by Kasha and coworkers to treat aggregates of small molecules. In polymer assemblies, intrachain through-bond interactions lead to J-aggregate behavior, whereas interchain Coulombic interactions lead to H-aggregate behavior. The photophysics of common emissive conjugated polymer films are determined by a competition between intrachain, J-favoring interactions and interchain, H-favoring interactions. We review formalisms describing absorption and photoluminescence lineshapes, based on intra- and intermolecular excitonic coupling, electron-vibrational coupling, and correlated energetic disorder. Examples include regioregular polythiophenes, pheneylene-vinylenes, and polydiacetylene.

The $B_s^0\\to J/\\psi K_S^0$ branching fraction is measured in a data sample corresponding to 0.41$fb^{-1}$ of integrated luminosity collected with the LHCb detector at the LHC. This channel is sensitive to the penguin contributions affecting the sin2$\\beta$ measurement from $B^0\\to J/\\psi K_S^0$ The time-integrated branching fraction is measured to be $BF(B_s^0\\to J/\\psi K_S^0)=(1.83\\pm0.28)\\times10^{-5}$. This is the most precise measurement to date.

Study of J/ψ production from the data recorded during 1991 with the L3 detector. The J/ψ is identified by its decay J/ψ - μ''+μ''- in the invariant mass spectrum of two muons. With our analysis results we have calculated the branching ratios Br(Z''0 -J/ψ + X) = (3.4 +- 0.7 (statistic)+- 0.2 (systematic)) x 10 3 and Br(b-> J/ψ+ X) = (1.20 +- 0.25 (statistic) +0.15 (systematic))%.

We measure the mean lifetime tau=2/(Gamma_{L}+Gamma_{H}) and the decay-width difference DeltaGamma=Gamma_{L}-Gamma_{H} of the light and heavy mass eigenstates of the B_{s}{0} meson, B_{sL}{0} and B_{sH}{0}, in B_{s}{0}-->J/psivarphi decays using 1.7 fb;{-1} of data collected with the CDF II detector at the Fermilab Tevatron pp[over ] collider. Assuming CP conservation, a good approximation for the B_{s}{0} system in the standard model, we obtain DeltaGamma=0.076_{-0.063}{+0.059}(stat)+/-0.006(syst) ps{-1} and tau=1.52+/-0.04(stat)+/-0.02(syst) ps, the most precise measurements to date. Our constraints on the weak phase and DeltaGamma are consistent with CP conservation.

We report the first search for CP-violating decays of the Υ(4S) using a data sample that contains 535×106 Υ(4S) mesons with the Belle detector at the KEKB asymmetric-energy e+e- collider. A partial reconstruction technique is employed to enhance the signal sensitivity. No significant signals were observed. We obtain an upper limit of 4×10-7 at the 90% confidence level for the branching fractions of the CP violating modes, Υ(4S)→B0B¯0→J/ψKS0+J/ψ(ηc)KS0. Extrapolating the result, we find that an observation with 5σ significance is expected with a 30ab-1 data sample, which is within the reach of a future super B factory.

We present a measurement of the time-dependent CP-violating asymmetry in B(s)(0) → J/ψϕ decays, using data collected with the LHCb detector at the LHC. The decay time distribution of B(s)(0) → J/ψϕ is characterized by the decay widths Γ(H) and Γ(L) of the heavy and light mass eigenstates, respectively, of the B(s)(0) - B(s)(0) system and by a CP-violating phase ϕ(s). In a sample of about 8500 B(s)(0) → J/ψϕ events isolated from 0.37 fb(-1) of pp collisions at sqrt[s] = 7 TeV, we measure ϕ(s) = 0.15 ± 0.18(stat) ± 0.06(syst) rad. We also find an average B(s)(0) decay width Γ(s) ≡ (Γ(L) + Γ(H))/2 = 0.657 ± 0.009(stat) ± 0.008(syst) ps(-1) and a decay width difference ΔΓ(s) ≡ Γ(L) - Γ(H) = 0.123 ± 0.029(stat) ± 0.011(syst) ps(-1). Our measurement is insensitive to the transformation (ϕ(s),ΔΓ(s)) ↦ (π - ϕ(s), -ΔΓ(s)).

The first observation of the $\\overline{B}^0 \\rightarrow J/\\psi K^{+}K^{-}$ decay is presented with a data sample corresponding to an integrated luminosity of 1.0 $\\rm fb^{-1}$ of $pp$ collisions at a center-of-mass energy of 7 TeV collected with the LHCb detector. The branching fraction is measured to be $\\mathcal{B}(\\overline{B}^0 \\rightarrow J/\\psi K^{+}K^{-}) = (2.53\\pm 0.31 \\pm 0.19)\\times 10^{-6}$, where the first uncertainty is statistical and the second is systematic. An amplitude analysis of the final state in the $\\overline{B}^0 \\rightarrow J/\\psi K^{+}K^{-}$ decay is performed to separate resonant and nonresonant contributions in the $K^{+}K^{-}$ spectrum. Evidence of the $a_0(980)$ resonance is reported with statistical significance of 3.9 standard deviations. The corresponding product branching fraction is measured to be $\\mathcal{B}(\\overline{B}^0 \\rightarrow J/\\psi a_0(980),~a_0(980)\\rightarrow K^{+}K^{-})=(4.70\\pm3.31\\pm0.72)\\times10^{-7}$, yielding an upper limit of $\\mathcal{B}(\\ov...

Measurements of CP violation in B{sub d}{sup 0}→J/ψK{sub S}{sup 0} and B{sub s}{sup 0}→J/ψϕ decays play key roles in testing the quark-flavour sector of the Standard Model. The theoretical interpretation of the corresponding observables is limited by uncertainties from doubly Cabibbo-suppressed penguin topologies. With continuously increasing experimental precision, it is mandatory to get a handle on these contributions, which cannot be calculated reliably in QCD. In the case of the measurement of sin 2β from B{sub d}{sup 0}→J/ψK{sub S}{sup 0}, the U-spin-related decay B{sub s}{sup 0}→J/ψK{sub S}{sup 0} offers a tool to control the penguin effects. As the required measurements are not yet available, we use data for decays with similar dynamics and the SU(3) flavour symmetry to constrain the size of the expected penguin corrections. We predict the CP asymmetries of B{sub s}{sup 0}→J/ψK{sub S}{sup 0} and present a scenario to fully exploit the physics potential of this decay, emphasising also the determination of hadronic parameters and their comparison with theory. In the case of the benchmark mode B{sub s}{sup 0}→J/ψϕ used to determine the B{sub s}{sup 0}-B-bar{sub s}{sup 0} mixing phase ϕ{sub s} the penguin effects can be controlled through B{sub d}{sup 0}→J/ψρ{sup 0} and B{sub s}{sup 0}→J/ψ ( K)-bar {sup ∗0} decays. The LHCb collaboration has recently presented pioneering results on this topic. We analyse their implications and present a roadmap for controlling the penguin effects.
LHCb: Measurement of the time-dependent CP asymmetry in $B^{0} \\rightarrow J/\\psi K_S^0$

The LHCb is one of the LHC experiments, specially designed to study CP violation and rare decays of b-quark. In this scenario, the decay $B^{0} \\rightarrow J/\\psi K_S^0$ is a well-known mode to study CP violation. The final state is the same for both CP eigenstates $B^0$ and $\\overline{B^0}$, which enables the interference through the b-quark oscillations.The CKM angle $\\beta$ can be extracted from the above decay. The time dependent decay rate asymmetry can be written as: $$ \\mathcal{A}_{J/\\psi K_S^0} (t) = S_{J/\\psi K_S^0} \\sin(\\Delta m_d t) - C_{J/\\psi K_S^0} \\cos( \\Delta m_d t) $$ where, in the standard model, the parameters $S_{J/\\psi K_S^0}$ and $C_{J/\\psi K_S^0}$ are connected to the CKM angle $\\beta$ through: $$S_{J/\\psi K_S^0} = \\sin 2 \\beta \\, \\rm{ and } \\, C_{J/\\psi K_S^0} = 0 $$ Here we report the time-dependent analysis in the $B^{0} \\rightarrow J/\\psi (\\mu^{+} \\mu^{-}) K_S^0 (\\pi^{+} \\pi^{-})$ decays.

First evidence of the B{sup 0}{yields}J/{psi}{omega} decay is found and the B{sub s}{sup 0}{yields}J/{psi}{eta} and B{sub s}{sup 0}{yields}J/{psi}{eta}{sup Prime} decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb{sup -1} collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of {radical}(s)=7 TeV. The branching fractions of these decays are measured relative to that of the B{sup 0}{yields}J/{psi}{rho}{sup 0} decay: (B(B{sup 0}{yields}J/{psi}{omega}))/(B(B{sup 0}{yields}J/{psi}{rho}{sup 0})) =0.89{+-}0.19(stat){sub -0.13}{sup +0.07}(syst), (B(B{sub s}{sup 0}{yields}J/{psi}{eta}))/(B(B{sup 0}{yields}J/{psi}{rho}{sup 0})) =14.0{+-}1.2(stat){sub -1.5}{sup +1.1}(syst){sub -1.0}{sup +1.1}((f{sub d})/(f{sub s}) ), (B(B{sub s}{sup 0}{yields}J/{psi}{eta}{sup Prime }))/(B(B{sup 0}{yields}J/{psi}{rho}{sup 0})) =12.7{+-}1.1(stat){sub -1.3}{sup +0.5}(syst){sub -0.9}{sup +1.0}((f{sub d})/(f{sub s}) ), where the last uncertainty is due to the knowledge of f{sub d}/f{sub s}, the ratio of b-quark hadronization factors that accounts for the different production rate of B{sup 0} and B{sub s}{sup 0} mesons. The ratio of the branching fractions of B{sub s}{sup 0}{yields}J/{psi}{eta}{sup Prime} and B{sub s}{sup 0}{yields}J/{psi}{eta} decays is measured to be (B(B{sub s}{sup 0}{yields}J/{psi}{eta}{sup Prime }))/(B(B{sub s}{sup 0}{yields}J/{psi}{eta})) =0.90{+-}0.09(stat){sub -0.02}{sup +0.06}(syst).

We present high-resolution CO(1-0) observations of the lensed submillimeter galaxy (SMG) SMM J14011+0252 at z = 2.6. Comparison to the previously detected CO(3-2) line gives an intensity ratio of r {sub 3,1} = 0.97 {+-} 0.16 in temperature units, larger than is typical for SMGs but within the range seen in the low-z ultraluminous infrared galaxy population. Combining our new data with previous mid-J CO observations, we perform a single-phase large velocity gradient (LVG) analysis to constrain the physical conditions of the molecular gas. Acceptable models have significant degeneracies between parameters, even when we rule out all models that produce optically thin emission, but we find that the bulk of the molecular gas has T {sub kin} = 20-60 K, n{sub H{sub 2}}{approx}10{sup 4}-10{sup 5} cm{sup -3}, and N {sub CO}/{Delta}v = 10{sup 17.00{+-}0.25} cm{sup -2} km{sup -1} s. For our best-fit models to self-consistently recover a typical CO-to-H{sub 2} abundance and a plausible degree of virialization, the local velocity gradient in the molecular gas must be substantially larger than its galaxy-wide average. This conclusion is consistent with a scenario in which SMM J14011+0252 has a fairly face-on orientation and a molecular interstellar medium composed of many unresolved clouds. Using previous H{alpha} observations, we find that SMM J14011+0252 has a spatially resolved star formation rate versus molecular gas surface density relation inconsistent with those of 'normal' local star-forming galaxies, even if we adopt a local 'disk-like' CO-to-H{sub 2} conversion factor as motivated by our LVG analysis. This discrepancy supports the inference of a star formation relation for high-z starbursts distinct from the local relation that is not solely due to differing choices of gas mass conversion factor.

The effective lifetime of the $\\overline{B}^0_s$ meson in the decay mode $\\overline{B}^0_s \\to J\\psi f_0(980)$ is measured using 1.0fb$^{-1}$ of data collected in $pp$ collisions at $\\sqrt{s} = 7$,TeV with the LHCb detector. The result is $1.700 \\pm 0.040 \\pm 0.026 \\,\\mathrm{ps}$ where the first uncertainty is statistical and the second systematic. As the final state is $CP$-odd, and $CP$ violation in this mode is measured to be small, the lifetime measurement can be translated into a measurement of the decay width of the heavy $\\overline{B}^0_s$ mass eigenstate, $\\Gamma_{\\rm H} = 0.588 \\pm 0.014 \\pm 0.009 \\,\\rm{ps}^{-1}$.

The lifetime of the $B^{0}_{s}$ meson is measured in the decay channel $B^{0}_{s} \\to J/\\psi\\mbox{ }\\pi^+ \\pi^-$ with $880 \\leq M_{\\pi^+\\pi^-} \\leq 1080$ MeV/$c^2$, which is mainly a CP-odd state and dominated by the $f_{0}(980)$ resonance. In 10.4 fb$^{-1}$ of data collected with the D0 detector in Run II of the Tevatron, the lifetime of the $B^{0}_{s}$ meson is measured to be $\\tau(B^{0}_{s}) = 1.70\\pm 0.14 \\mbox{ (stat)} \\pm 0.05 \\mbox{ (syst) ps}$. Neglecting CP violation in $B_s^0/\\bar{B}_s^0$ mixing, the measurement can be translated into the width of the heavy mass eigenstate of the $B^0_s$, $\\Gamma_H = 0.59 \\pm 0.05 \\mbox{ (stat)} \\pm 0.02 \\mbox{ (syst)} \\mbox{ ps$^{-1}$}$.

The first measurement of decay-time-dependent CP asymmetries in the decay $B_s^0\\rightarrow J/\\psi K_{\\rm S}^0$ and an updated measurement of the ratio of branching fractions $\\mathcal{B}(B_s^0\\rightarrow J/\\psi K_{\\rm S}^0)/\\mathcal{B}(B_d^0\\rightarrow J/\\psi K_{\\rm S}^0)$ are presented. The results are obtained using data corresponding to an integrated luminosity of 3.0 fb$^{-1}$ of proton-proton collisions recorded with the LHCb detector at centre-of-mass energies of 7 and 8 TeV. The results on the CP asymmetries are $A_{\\Delta\\Gamma}(B_s^0\\rightarrow J/\\psi K_{\\rm S}^0) = 0.49_{-0.65}^{+0.77}(stat) \\pm 0.06(syst)$, $C_{\\rm dir}(B_s^0\\rightarrow J/\\psi K_{\\rm S}^0) = -0.28 \\pm 0.41(stat) \\pm 0.08(syst)$ and $S_{\\rm mix}(B_s^0\\rightarrow J/\\psi K_{\\rm S}^0) = -0.08 \\pm 0.40(stat) \\pm 0.08(syst)$. The ratio $\\mathcal{B}(B_s^0\\rightarrow J/\\psi K_{\\rm S}^0)/\\mathcal{B}(B_d^0\\rightarrow J/\\psi K_{\\rm S}^0)$ is measured to be $0.0431 \\pm 0.0017(stat) \\pm 0.0012(syst) \\pm 0.0025(f_s/f_d)$, where the last uncerta...

This Letter reports a measurement of the $CP$ violation observables $S_{J/\\psi K^0_{\\rm S}}$ and $C_{J/\\psi K^0_{\\rm S}}$ in the decay channel $B^0 \\rightarrow J/\\psi K^0_{\\rm S}$ performed with 1.0 fb$^{-1}$ of $pp$ collisions at $\\sqrt{s}=7$ TeV collected by the LHCb experiment. The fit to the data yields $S_{J/\\psi K^0_{\\rm S}}= 0.73 \\pm 0.07 {\\rm (stat)} \\pm 0.04 {\\rm (syst)}$ and $C_{J/\\psi K^0_{\\rm S}}= 0.03 \\pm 0.09 {\\rm (stat)} \\pm 0.01 {\\rm (syst)}$. Both values are consistent with the current world averages and within expectations from the Standard Model.

This paper reports the first measurement of the effective $B_s^0\\rightarrow J/\\psi K_{\\mathrm S}^0$ lifetime and an updated measurement of its time-integrated branching fraction. Both measurements are performed with a data sample, corresponding to an integrated luminosity of $1.0\\:\\text{fb}^{-1}$ of $pp$ collisions, recorded by the LHCb experiment in 2011 at a centre-of-mass energy of $7\\:\\text{TeV}$. The results are: $\\tau_{J/\\psi K_{\\mathrm S}^0}^{\\text{eff}} = 1.75 \\pm 0.12\\:(\\text{stat}) \\pm 0.07\\:(\\text{syst})\\:\\text{ps}$ and $\\mathcal{B}(B_s^0\\rightarrow J/\\psi K_{\\mathrm S}^0)=(1.97 \\pm 0.23)\\times 10^{-5}$. For the latter measurement, the uncertainty includes both statistical and systematic sources.
INTERSTELLAR EXTINCTION LAW TOWARD THE GALACTIC CENTER III: J, H, KS BANDS IN THE 2MASS AND THE MKO SYSTEMS, AND 3.6, 4.5, 5.8, 8.0 μm IN THE SPITZER/IRAC SYSTEM

We have determined interstellar extinction law toward the Galactic center (GC) at the wavelength from 1.2 to 8.0 μm, using point sources detected in the IRSF/SIRIUS near-infrared (NIR) survey and those in the Two Micron All Sky Survey (2MASS) and Spitzer/IRAC/GLIMPSE II catalogs. The central region |l | ∼ 0 0 and |b | ∼ 0 0 has been surveyed in the J, H, and K S bands with the IRSF telescope and the SIRIUS camera whose filters are similar to the Mauna Kea Observatories (MKO) NIR photometric system. Combined with the GLIMPSE II point source catalog, we made K S versus K S - λ color-magnitude diagrams (CMDs) where λ=3.6, 4.5, 5.8, and 8.0 μm. The K S magnitudes of bulge red clump stars and the K S - λ colors of red giant branches are used as a tracer of the reddening vector in the CMDs. From these magnitudes and colors, we have obtained the ratios of total-to-selective extinction A K S /E K S -λ for the four IRAC bands. Combined with A λ /A K S for the J and H bands derived by Nishiyama et al., we obtain A J :A H :A K S :A [3.6] :A [4.5] :A [5.8] :A [8.0] = 3.02:1.73:1:0.50:0.39:0.36:0.43 for the line of sight toward the GC. This confirms the flattening of the extinction curve at λ ∼> 3 μm from a simple extrapolation of the power-law extinction at shorter wavelengths, in accordance with recent studies. The extinction law in the 2MASS J, H, and K S bands has also been calculated, and good agreement with that in the MKO system is found. Thus, it is established that the extinction in the wavelength range of J, H, and K S is well fitted by a power law of steep decrease A λ ∝ λ -2.0 toward the GC. In nearby molecular clouds and diffuse interstellar medium, the lack of reliable measurements of the total-to-selective extinction ratios hampers unambiguous determination of the extinction law; however, observational results toward these lines of sight cannot be reconciled with a single extinction law.

Study of J/{psi} production from the data recorded during 1991 with the L3 detector. The J/{psi} is identified by its decay J/{psi} - {mu}''+{mu}''- in the invariant mass spectrum of two muons. With our analysis results we have calculated the branching ratios Br(Z''0 -J/{psi} + X) = (3.4 +- 0.7 (statistic)+- 0.2 (systematic)) x 10{sup 3} and Br(b-> J/{psi}+ X) = (1.20 +- 0.25 (statistic) +0.15 (systematic))%.

We performed CO(J = 1-0, 2-1, and 3-2) observations toward an H II region RCW 32 in the Vela Molecular Ridge. The CO gas distribution associated with the H II region was revealed for the first time at a high resolution of 22″. The results revealed three distinct velocity components which show correspondence with the optical dark lanes and/or Hα distribution. Two of the components show complementary spatial distribution which suggests collisional interaction between them at a relative velocity of ˜ 4 km s-1. Based on these results, we present a hypothesis that a cloud-cloud collision determined the cloud distribution and triggered formation of the exciting star ionizing RCW 32. The collision time scale is estimated from the cloud size and the velocity separation to be ˜2 Myr and the collision terminated ˜1 Myr ago, which is consistent with the age of the exciting star and the associated cluster. By combing the previous works on the H II regions in the Vela Molecular Ridge, we argue that the majority (at least four) of the H II regions in the Ridge were formed by triggering of cloud-cloud collision.

We study the rare B meson decays B^±,0 → J/ψK⁺K^–K^±,0, B^±,0 → J/ψΦK^±,0, and search for B⁰ → J/ψΦ, using 469 million BB¯ events collected at the Υ(4S) resonance with the BABAR detector at the PEP-II e⁺e^– asymmetric energy collider. We present new measurements of branching fractions and a study of the J/ψΦ mass distribution in search of new charmonium-like states. In addition, we search for the decay B⁰ → J/ψΦ and find no evidence of a signal.

The Crystal Ball detector at SPEAR has been used to investigate the decays psi'→etaJ/psi and psi'→π 0 J/psi resulting from production of 776 000 psi'. Our measurement for the branching ratio of the eta mode is (2.18 +- 0.14 +- 0.35)%, where the first error results from statistics and acceptance uncertainties, and the second error is systematic; this is almost a factor of 2 smaller than found in early experiments. For the isospin-nonconserving π 0 mode, a branching ratio (0.09 +- 0.02 +- 0.01)% is obtained

We report a measurement of the well-established CP violation in $B_0 \\to J/\\psi K_s^0$ decays. We perform a time-dependent analysis of the decays reconstructed in 35 pb $^{-1}$ of LHCb data that was taken in 2010. We measure the CP asymmetry parameter $S_{ J/\\psi K_s^0}$ , which is connected to the CKM angle $\\beta$ through $S_{ J/\\psi K_s^0}$ = sin2$\\beta$, neglecting CP violation in $B^0$-$ \\overline{B^0}$ mixing and decay. We find $S_{ J/\\psi K_s^0} $ = 0.53$^{+0.28}_{-0.29}$(stat) $\\pm$ 0.05(syst).

The first observation of the Cabibbo-suppressed decay $\\Lambda_b^0\\rightarrow J/\\psi p \\pi^-$ is reported using a data sample of proton-proton collisions at 7 and 8 TeV, corresponding to an integrated luminosity of 3 $\\rm fb^{-1}$. A prominent signal is observed and the branching fraction relative to the decay mode $\\Lambda_b^0\\rightarrow J/\\psi p K^-$ is determined to be $$ \\frac{{\\cal B}(\\Lambda_b^0\\rightarrow J/\\psi p \\pi^-)}{{\\cal B}(\\Lambda_b^0\\rightarrow J/\\psi p K^-)}=0.0824\\pm0.0025\\:(\\text{stat})\\pm0.0042\\:(\\text{syst}). $$ A search for direct CP violation is performed.

The $B_s^0 \\rightarrow J/\\psi \\phi \\phi$ decay is observed in $pp$ collision data corresponding to an integrated luminosity of 3 fb$^{-1}$ recorded by the LHCb detector at centre-of-mass energies of 7 TeV and 8 TeV. This is the first observation of this decay channel, with a statistical significance of 15 standard deviations. The mass of the $B_s^0$ meson is measured to be $5367.08\\,\\pm \\,0.38\\,\\pm\\, 0.15$ MeV/c$^2$. The branching fraction ratio $\\mathcal{B}(B_s^0 \\rightarrow J/\\psi \\phi \\phi)/\\mathcal{B}(B_s^0 \\rightarrow J/\\psi \\phi)$ is measured to be $0.0115\\,\\pm\\, 0.0012\\, ^{+0.0005}_{-0.0009}$. In both cases, the first uncertainty is statistical and the second is systematic. No evidence for non-resonant $B_s^0 \\rightarrow J/\\psi \\phi K^+ K^-$ or $B_s^0 \\rightarrow J/\\psi K^+ K^- K^+ K^-$ decays is found.

Full Text Available In this paper‎, ‎we introduce the new notion of strongly $J $-clean rings associated with polynomial identity $g(x=0$‎, ‎as a generalization of strongly $ J $-clean rings‎. ‎We denote strongly $J $-clean rings associated with polynomial identity $g(x=0$ by strongly $ g(x $-$J $-clean rings‎. ‎Next‎, ‎we investigate some properties of strongly $ g(x $-$ J $-clean.

The data sample of $\\Lambda_b^0\\to J/\\psi p K^-$ decays acquired with the LHCb detector from 7 and 8~TeV $pp$ collisions, corresponding to an integrated luminosity of 3 fb$^{-1}$, is inspected for the presence of $J/\\psi p$ or $J/\\psi K^-$ contributions with minimal assumptions about $K^- p$ contributions. It is demonstrated at more than 9 standard deviations that $\\Lambda_b^0\\to J/\\psi p K^-$ decays cannot be described with $K^- p$ contributions alone, and that $J/\\psi p$ contributions play a dominant role in this incompatibility. These model-independent results support the previously obtained model-dependent evidence for $P_c^+\\to J/\\psi p$ charmonium-pentaquark states in the same data sample.

The data sample of Λ_{b}^{0}→J/ψpK^{-} decays acquired with the LHCb detector from 7 and 8 TeV pp collisions, corresponding to an integrated luminosity of 3 fb^{-1}, is inspected for the presence of J/ψp or J/ψK^{-} contributions with minimal assumptions about K^{-}p contributions. It is demonstrated at more than nine standard deviations that Λ_{b}^{0}→J/ψpK^{-} decays cannot be described with K^{-}p contributions alone, and that J/ψp contributions play a dominant role in this incompatibility. These model-independent results support the previously obtained model-dependent evidence for P_{c}^{+}→J/ψp charmonium-pentaquark states in the same data sample.

This Letter reports a measurement of the CP violation observables S{sub J/ψK{sub S{sup 0}}} and C{sub J/ψK{sub S{sup 0}}} in the decay channel B{sup 0}→J/ψK{sub S}{sup 0} performed with 1.0 fb{sup −1} of pp collisions at √(s)=7 TeV collected by the LHCb experiment. The fit to the data yields S{sub J/ψK{sub S{sup 0}}}=0.73±0.07(stat)±0.04(syst) and C{sub J/ψK{sub S{sup 0}}}=0.03±0.09(stat)±0.01(syst). Both values are consistent with the current world averages and within expectations from the Standard Model.
L-J phase in a Cu2.2Mn0.8Al alloy

1995-06-01

A new type of precipitate (designated L-J phase) with two variants was observed within the (DO3 + L21) matrix in a Cu2.2Mn0.8Al alloy. Transmission electron microscopy examinations indicated that the L-J phase has an orthorhombic structure with lattice parameters a = 0.413 nm, b = 0.254 nm and c = 0.728 nm. The orientation relationship between the L-J phase and the matrix is (100)L-J//(011) m , (010)L-J//(111) m and (001)L-J//(211) m . The rotation axis and rotation angle between two variants of the L-J phase are [021] and 90 deg. The L-J phase has never been observed in various Cu-Al, Cu-Mn, and Cu-Al-Mn alloy systems before.
Induced absorption spectra of the infrared fundamental band of molecular deuterium at 77 K: S1( J)+S0( J) transitions

The collision-induced spectra of the fundamental band of normal D 2 in the high frequency region 3200--3700 cm -1 were recorded for gas densities in the range 80--140 amagat at 77 K with a 2 m absorption cell. The contribution to the intensity of the band in this region comes from the high frequency wings of quadrupolar transitions S 1 ( J) and Q 1 ( J)+S 0 ( J) with J = 0 and 1, and from the group of transitions S 1 (2) and Q 1 ( J)+S 0 (2) with J = 0, 1, and 2 as well as from the relatively weaker double rotational transitions of the type S 1 ( J)+S 0 ( J); the latter transitions arise from the intermolecular interaction between the anisotropic component of the polarizability of one of the colliding pairs of molecules and the quadrupole field of the other. The experimental profiles were analyzed by assuming appropriate line shape functions and using the theoretical matrix elements of the quadrupole moment, isotropic polarizability, and anisotropy of polarizability of the D 2 molecule. From this analysis the characteristic half-width parameters delta/sub q/2 and delta/sub q/4 of the quadrupolar transitions and the binary and ternary absorption coefficients of the S 1 ( J)+S 0 ( J) transitions have been obtained. The experimental value of the binary absorption coefficient of S 1 (0)+S 0 (0) is (2.2 +- 0.1) x 10 -9 cm -1 amagat -2 and the corresponding theoretical value is 1.53 x 10 -9 cm -1 amagat -2
Measurement of the branching ratio Γ(Λb0→ψ(2SΛ0/Γ(Λb0→J/ψΛ0 with the ATLAS detector

Full Text Available An observation of the Λb0→ψ(2SΛ0 decay and a comparison of its branching fraction with that of the Λb0→J/ψΛ0 decay has been made with the ATLAS detector in proton–proton collisions at s=8 TeV at the LHC using an integrated luminosity of 20.6 fb−1. The J/ψ and ψ(2S mesons are reconstructed in their decays to a muon pair, while the Λ0→pπ− decay is exploited for the Λ0 baryon reconstruction. The Λb0 baryons are reconstructed with transverse momentum pT>10 GeV and pseudorapidity |η|<2.1. The measured branching ratio of the Λb0→ψ(2SΛ0 and Λb0→J/ψΛ0 decays is Γ(Λb0→ψ(2SΛ0/Γ(Λb0→J/ψΛ0=0.501±0.033(stat±0.019(syst, lower than the expectation from the covariant quark model.

The results of searches for $B^0_{(s)} \\to J/\\psi p\\bar{p}$ and $B^+ \\to J/\\psi p\\bar{p}\\pi^+$ decays are reported. The analysis is based on a data sample, corresponding to an integrated luminosity of 1.0 fb$^{-1}$ of $pp$ collisions, collected with the LHCb detector. An excess with 2.8 $\\sigma$ significance is seen for the decay $B^0_{s} \\to J/\\psi p\\bar{p}$ and an upper limit on the branching fraction is set at the 90% confidence level: $B(B^0_s \\to J/\\psi p\\bar{p}) \\lt$ 4.8 x 10$^{-6}$, which is the first such limit. No significant signals are seen for $B^0 \\to J/\\psi p\\bar{p}$ and $B^+ \\to J/\\psi p\\bar{p}\\pi^+$ decays, for which the corresponding limits are set: $B(B^0 \\to J/\\psi p\\bar{p}) \\lt$ 5.2 x 10$^{-7}$, which significantly improves the existing limit; and $B(B^+ \\to J/\\psi p\\bar{p}\\pi^+) \\lt$ 5.0 x 10$^{-7}$, which is the first limit on this branching fraction.

The B{sub s}{sup 0}{yields}J/{psi}K{sub S}{sup 0} branching fraction is measured in a data sample corresponding to 0.41 fb{sup -1} of integrated luminosity collected with the LHCb detector at the LHC. This channel is sensitive to the penguin contributions affecting the sin2{beta} measurement from B{sup 0}{yields}J/{psi}K{sub S}{sup 0}. The time-integrated branching fraction is measured to be B(B{sub s}{sup 0}{yields}J/{psi}K{sub S}{sup 0})=(1.83{+-}0.28) Multiplication-Sign 10{sup -5}. This is the most precise measurement to date.

B+ -> J/psi(mm)K+ and B0 ->J/psi(mm)K* are suitable control channels for the calibration of flavour tagging for CP measurements in Bs ->J/psi(mm) phi and B0 ->J/psi(mm)KS channels; in the first case if opposite side tagging only is considered. In this note we describe the calibration of the probability of mistag performed with B+ ->J/psi(mm)K+ events and the measurement of the mistag performed with B0 ->J/psi(mm)K* events in a fit to flavour oscillation as a function of proper time. Models are developed to extract this information from selected events taking into account different background components. An expected statistical sensitivity on the average opposite side mistag rate sigma(wOS)/ wOS = 0.3 % is obtained for B0 ->J/psi(mm)K* events, in 2 fb-1 of data.

A sample of 114±11 $B_s^0 → J/ψK^-π^+$ signal events obtained with 0.37 fb$^{-1}$ of pp collisions at √s=7 TeV collected by the LHCb experiment is used to measure the branching fraction and polarization amplitudes of the $B_s^0 → J/ψK̅ ^{*0}$ decay, with $K̅ ^{*0} → K^-π^+$. The $K^-π^+$ mass spectrum of the candidates in the $B_s^0$ peak is dominated by the $K̅ ^{*0}$ contribution. Subtracting the nonresonant $K^-π^+$ component, the branching fraction of $B_s^0 → J/ψK̅ ^{*0}$ is $(4.4_{-0.4}^{+0.5}±0.8)×10^{-5}$, where the first uncertainty is statistical and the second is systematic. A fit to the angular distribution of the decay products yields the $K^{*0}$ polarization fractions $f_L=0.50±0.08±0.02$ and $f_{∥}=0.19_{-0.08}^{+0.10}±0.02$.

This paper reports the first measurement of the effective B{sub s}{sup 0}→J/ψK{sub S}{sup 0} lifetime and an updated measurement of its time-integrated branching fraction. Both measurements are performed with a data sample, corresponding to an integrated luminosity of 1.0 fb{sup −1} of pp collisions, recorded by the LHCb experiment in 2011 at a centre-of-mass energy of 7 TeV. The results are: τ{sub J/ψK{sub S{sup 0eff}}}=1.75±0.12(stat)±0.07(syst) ps and B(B{sub s}{sup 0}→J/ψK{sub S}{sup 0})=(1.97±0.23)×10{sup −5}. For the latter measurement, the uncertainty includes both statistical and systematic sources.

Highlights: • A serial of MgB_2 superconducting films from 10 nm to 8 µm have been prepared. • T_c and J_c (5 K, 0 T) of films are high. • J_c (5 K, 0 T) reaches its maximum 2.3 × 10"8 A cm"−"2 for 100 nm films. • The relationship between thickness and J_c has been discussed in detail. - Abstract: MgB_2 superconducting films, whose thicknesses range from 10 nm to 8 µm, have been fabricated on SiC substrates by hybrid physical–chemical vapor deposition (HPCVD) method. It is the first time that the T_c and the J_c of MgB_2 films are studied on such a large scale. It is found that with the increasing of thickness, T_c elevates first and then keeps roughly stable except for some slight fluctuations, while J_c (5 K, 0 T) experiences a sharp increase followed by a relatively slow fall. The maximum J_c (5 K, 0 T) = 2.3 × 10"8 A cm"−"2 is obtained for 100 nm films, which is the experimental evidence for preparing high-quality MgB_2 films by HPCVD method. Thus, this work may provide guidance on choosing the suitable thickness for applications. Meanwhile, the films prepared by us cover ultrathin films, thin films and thick films, so the study on them will bring a comprehensive understanding of MgB_2 films.

Full Text Available We study the decays of J/ψ and ψ(3686 to the final states Σ(13850Σ¯(13850 and Ξ0Ξ¯0 based on a single baryon tag method using data samples of (1310.6±7.0×106 J/ψ and (447.9±2.9×106 ψ(3686 events collected with the BESIII detector at the BEPCII collider. The decays to Σ(13850Σ¯(13850 are observed for the first time. The measured branching fractions of J/ψ and ψ(3686 to Ξ0Ξ¯0 are in good agreement with, and much more precise than, the previously published results. The angular parameters for these decays are also measured for the first time. The measured angular decay parameter for J/ψ→Σ(13850Σ¯(13850, α=−0.64±0.03±0.10, is found to be negative, different to the other decay processes in this measurement. In addition, the “12% rule” and isospin symmetry in the decays of J/ψ and ψ(3686 to ΞΞ¯ and Σ(1385Σ¯(1385 are tested.

Results are presented for the decays of B {yields} J/{psi}{eta}K and B{sup {+-}} {yields} DK{sup {+-}}, respectively, with experimental data collected with BABAR detector at PEP-II, located at Stanford Linear Accelerator Center (SLAC). With 90 x 10{sup 6} B{bar B} events at the {Upsilon}(4S) resonance, we obtained branching fractions of {Beta}(B{sup {+-}} {yields} J/{psi}{eta}K{sup {+-}}) = [10.8 {+-} 2.3(stat) {+-} 2.4(syst)] x 10{sup -5} and {Beta}(B{sup 0} {yields} J/{psi}{eta}K{sub S}{sup 0}) = [8.4 {+-} 2.6(stat) {+-} 2.7(syst)] x 10{sup -5}; and we set an upper limit of {Beta}[B{sup {+-}} {yields} X(3872)K{sup {+-}} {yields} J/{psi}{eta}K{sup {+-}}] < 7.7 x 10{sup -6} at 90% confidence level. The branching fraction of decay chain {Beta}(B{sup {+-}} {yields} DK{sup {+-}} {yields} {pi}{sup +}{pi}{sup -}{pi}{sup 0}K{sup {+-}}) = [5.5 {+-} 1.0(stat) {+-} 0.7(syst)] x 10{sup -6} with 229 x 10{sup 6} B{bar B} events at {Upsilon}(4S) resonance, here D represents the neutral D meson. The decay rate asymmetry is A = 0.02 {+-} 0.16(stat) {+-} 0.03(syst) for this full decay chain. This decay can be used to extract the unitarity angle {gamma}, a weak CP violation phase, through the interference of decay production of D{sup 0} and {bar D}{sup 0} to {pi}{sup +}{pi}{sup -}{pi}{sup 0}.

Using a data sample of 448.1 ×106 ψ (3686 ) events collected with the BESIII detector operating at the BEPCII, we perform search for the hadronic transition hc→π+π-J /ψ via ψ (3686 )→π0hc. No signals of the transition are observed, and the upper limit on the product branching fraction B (ψ (3686 )→π0hc)B (hc→π+π-J /ψ ) at the 90% confidence level (C.L.) is determined to be 2.0 ×10-6. This is the most stringent upper limit to date.

We present a complete analysis of the hyperfine structure of the MnH A 7Π-X 7Σ+ (0,0) band near 5680 Å, studied with sub-Doppler resolution by intermodulated fluorescence spectroscopy. Magnetic hyperfine interactions involving both the 55Mn (I=5/2) and 1H (I=1/2) nuclear spins are observed as well as 55Mn electric quadrupole effects. The manganese Fermi contact interaction in the X 7Σ+ state is the dominant contributor to the observed hyperfine splittings; the ΔF=0, ΔN=0, ΔJ=±1 matrix elements of this interaction mix the electron spin components of the ground state quite strongly at low N, destroying the ``goodness'' of J as a quantum number and inducing rotationally forbidden, ΔJ=±2 and ±3 transitions. The hyperfine splittings of over 50 rotational transitions covering all 7 spin components of both states were analyzed and fitted by least squares, allowing the accurate determination of 14 different hyperfine parameters. Using single electronic configurations to describe the A 7Π and X 7Σ+ states and Herman-Skillman atomic radial wave functions to represent the molecular orbitals, we calculated a priori values for the 55Mn and 1H hyperfine parameters which agree closely with experiment. We show that the five high-spin coupled Mn 3d electrons do not contribute to the manganese hyperfine structure but are responsible for the observed proton magnetic dipolar couplings. Furthermore, the results suggest that the Mn 3d electrons are not significantly involved in bonding and demonstrate that the molecular hyperfine interactions may be quantitatively understood using simple physical interpretations.

I reanalyse the Riess et al. (hereafter R11) Cepheid data using the revised geometric maser distance to NGC 4258 of Humphreys et al. (hereafter H13). I explore different outlier rejection criteria designed to give a reduced χ2 of unity and compare the results with the R11 rejection algorithm, which produces a reduced χ2 that is substantially less than unity and, in some cases, leads to underestimates of the errors on parameters. I show that there are sub-luminous low-metallicity Cepheids in the R11 sample that skew the global fits of the period-luminosity relation. This has a small but non-negligible impact on the global fits using NGC 4258 as a distance scale anchor, but adds a poorly constrained source of systematic error when using the Large Magellanic Cloud as an anchor. I also show that the small Milky Way Cepheid sample with accurate parallax measurements leads to a distance to NGC 4258 that is in tension with the maser distance. I conclude that H0 based on the NGC 4258 maser distance is H0 = 70.6 ± 3.3 km s-1 Mpc-1, compatible within 1σ with the recent determination from Planck for the base six-parameter Λ cold dark matter cosmology. If the H-band period-luminosity relation is assumed to be independent of metallicity and the three distance anchors are combined, I find H0 = 72.5 ± 2.5 km s-1 Mpc-1, which differs by 1.9σ from the Planck value. The differences between the Planck results and these estimates of H0 are not large enough to provide compelling evidence for new physics at this stage.

We present photometry in the R-band and linear polarimetry of two cataclysmic variables, namely IPHAS J025827.88 + 635234.9 and IPHAS J051814.33 + 294113.0. The data were obtained from 1-m class tele-scopes of the Aryabhatta Research Institute of Observational Sciences (ARIES; Nainital, India). In addition to the deep eclipse, strong short-period oscillations are also found. We derived a pulse period of (1203 ± 25) s for IPHAS J025827.88 + 635234.9 and (3277 ± 81) s for IPHAS J051814.33 + 294113.0. The presence of both orbital and spin modulations in these systems indicate that they belong to a class of intermediate polars. The full width at half depth of the eclipse is also found to be variable from epoch to epoch for IPHAS J025827.88 + 635234.9. The presence of a variable linear polarization of high value in these two sources indicates that these systems possess a strong magnetic field.

The measurement is based on results from analyses of the decays $B^0 \\to D^- \\pi^+$ ($D^- \\to K^+ \\pi^- \\pi^-$) and $B^0 \\to J\\ \\psi K^{*0}$ ($J\\ \\psi \\to \\mu^+ \\mu^-$, $K^{*0} \\to K^+ \\pi^-$) and their charge conjugated modes.

Measurement of mixing-induced $CP$ violation in $\\overline{B}^0_s$ decays is of prime importance in probing new physics. So far only the channel $\\overline{B}^0_s\\to J/\\psi\\phi$ has been used. Here we report on a measurement using an LHCb data sample of 0.41\\,fb$^{-1}$, in the $CP$ odd eigenstate $J/\\psi f_0(980)$, where $f_0(980)\\to\\pi^+\\pi^-$. A time dependent fit of the data with the $\\overline{B}^0_s$ lifetime and the difference in widths of the heavy and light eigenstates constrained to the values obtained from $\\overline{B}^0_s \\to J/\\psi\\phi$ yields a value of the $CP$ violating phase of $-0.44\\pm 0.44\\pm0.02~{\\rm\\,rad}$, consistent with the Standard Model expectation.

The decay B0 -> J/psi K0_S is reconstructed with J/psi -> e+ e- or mu+ mu- and K0_S -> pi+ pi-. From the full ALEPH dataset at LEP1 of about 4 million hadronic Z decays, 23 candidates are selected with an estimated purity of 71%. They are used to measure the CP asymmetry of this decay, given by sin 2beta in the Standard Model, with the result sin 2beta = 0.84 +0.82-1.04 +-0.16. This is combined with existing measurements from other experiments, and increases the confidence level that CP violation has been observed in this channel to 98%.

HCl^+ is a key intermediate in the interstellar chemistry of chlorine. It has been recently identified in space from Herschel's spectra and it has also been detected in the laboratory through its optical emission, infrared and mm-wave spectra. Now that Hershchel is decomissioned, further astrophysical studies on this radical ion will likely rely on ground-based observations in the mid-infrared. We have used a difference frequency laser spectrometer coupled to a hollow cathode discharge to measure the absorption spectrum of H35Cl^+ and H37Cl^+ in the v=0-1 band of the ^2Π state with Dopppler limited resolution. The accuracy of the individual measurements (˜ 10 MHz (3σ)) relies on a solid state wavemeter referenced to an iodine-stabilized Ar^+ laser. The new data are being fit using the CALPGM software from JPL, and the current status will be presented. M. De Luca et al., Astrophys. J. Lett. 751, L37 (2012) W. D. Sheasley and C. W. Mathews, J.

Study of Charmless Bd,s0 → h+h'-π0 decays in LHCb

International Nuclear Information System (INIS)

Roa Romero, D.A.

2013-01-01

This thesis work is about the identification of charmless three-body decays of neutral B mesons with a π 0 in the final state (B d,s 0 → h + h' - π 0 ) through the analysis of a 1.0 fb -1 data sample collected in 2011 by the LHCb experiment at the LHC. Those modes are sensitive to CKM parameters and allow to test Standard Model predictions related to CP violation. Some of them, such as B s 0 → K - π + π 0 and B s 0 → K + K - π 0 , have not been observed previously. This is the first analysis with energetic π 0 in LHCb. To evaluate the detector performance for π 0 , D *+ → D 0 (→ K - π + π 0 )π + decays have been selected. This provides a clean and high statistics sample of neutral pions used to study their energy calibration as well as the effectiveness of the π 0 /γ separation tool of the experiment. Radiative decays are indeed the most dangerous backgrounds for the study of B d,s 0 → h + h' - π 0 modes. To select B d,s 0 → h + h' - π 0 events, a dedicated trigger algorithm has been implemented. It complements the standard online selections and significantly improves the efficiency. Offline, obvious backgrounds, mainly from charm decays, are rejected applying simple criteria. The sample is then further purified using a multivariate classifier. At last, information from the ring imaging Cherenkov detectors allows to separate π + π - π 0 , K ± π ± π 0 and K + K - π 0 final states. A simultaneous fit of the reconstructed B mass spectra in the three sub-samples is used to extract the signal yields. It accounts for the different backgrounds remaining as well as for the signal cross-feeds from one sub-sample to the other. The B 0 → π + π - π 0 , B 0 → K + π - π 0 and B s 0 → K + K - π 0 contributions are clearly established. This is the first observation of the B s 0 → K + K - π 0 decay mode. (author)

This thesis presents the first measurement of $C\\!P$ violation in decays of $B^0_s$ and $\\overline{B^0_s}$ mesons into the final state $J\\!/\\psi K^0_{\\text{S}}$, where the $C\\!P$ observables allow to constrain the contribution of penguin topologies in $B^0\\!\\rightarrow J\\!/\\psi K^0_{\\text{S}}$ decays.

CAL3JHH: a Java program to calculate the vicinal coupling constants (3J H,H) of organic molecules.

Science.gov (United States)

Aguirre-Valderrama, Alonso; Dobado, José A

2008-12-01

Here, we present a free web-accessible application, developed in the JAVA programming language for the calculation of vicinal coupling constant (3J(H,H)) of organic molecules with the H-Csp3-Csp3-H fragment. This JAVA applet is oriented to assist chemists in structural and conformational analyses, allowing the user to calculate the averaged 3J(H,H) values among conformers, according to its Boltzmann populations. Thus, the CAL3JHH program uses the Haasnoot-Leeuw-Altona equation, and, by reading the molecule geometry from a protein data bank (PDB) file format or from multiple pdb files, automatically detects all the coupled hydrogens, evaluating the data needed for this equation. Moreover, a "Graphical viewer" menu allows the display of the results on the 3D molecule structure, as well as the plotting of the Newman projection for the couplings.

Study of CP violation in B⁰_s → J/ΨΦ decays at D0

Energy Technology Data Exchange (ETDEWEB)

Strom, Derek A. [Northwestern Univ., Evanston, IL (United States)

2008-12-01

In a universe dominated by matter, the source of CP violation may explain one of the greatest mysteries in particle physics: what happened to the antimatter? The Standard Model successfully describes CP violation in the B⁺ and B_d⁰ systems, yet insufficiently accounts for the observed matter-antimatter asymmetry. The Standard Model predicts a small value of CP violation in the B_s⁰ meson system, which has only recently been experimentally tested. A measurement of large, anomalous CP violation in the B_s⁰ system would be a clear indication of new physics sources beyond the Standard Model. This dissertation describes a study of CP violation in approximately 2000 B_s⁰ → J/ΨΦ decays reconstructed in a 2.8 fb^-1 data sample collected by the D0 Run II detector at Fermi National Accelerator Laboratory in Batavia, Illinois. This data was provided by p$\\bar{p}$ collisions at √s = 1.96 TeV delivered by the Tevatron accelerator between April 2002 and August 2007. Flavor-tagged B_s⁰ → J/Ψ(μ⁺μ^-)Φ(K⁺K^-) decays and an angular analysis are used to study the time evolution of the final state angular distributions. From this analysis, we measure the width difference between the heavy and light mass eigenstates, B_s^L and B_s^H , to be ΔΓ_s = 0.19 ± 0.07 and the CP-violating phase Φ_s = -0.57_-0.30^+0.24.

In this Letter the decay $\\overline{B}^0_s \\to J/\\psi K^+ K^-$ is investigated. Although the $J/\\psi \\phi$ channel is well known, final states at higher $K^+K^-$ masses have not previously been studied. In the $K^+K^-$ mass spectrum we observe a significant signal in the $f'_2(1525)$ region as well as a non-resonant component. The ratio of the rate in a $K^+K^-$ mass window of $\\pm 125$ MeV around the $f'_2$ relative to that in the $J/\\psi \\phi$ decay, where $\\phi \\to K^+K^-$, is $R=(19.4 \\pm 1.8 \\pm 1.0)$%. Our sample consists of $0.16$ fb$^{-1}$ collected with the LHCb detector using 7 TeV $pp$ collisions.
Mutacin H-29B is identical to mutacin II (J-T8

Full Text Available Abstract Background Streptococcus mutans produces bacteriocins named mutacins. Studies of mutacins have always been hampered by the difficulties in obtaining active liquid preparations of these substances. Some of them were found to be lantibiotics, defined as bacterial ribosomally synthesised lanthionine-containing peptides with antimicrobial activity. The goal of this study was to produce and characterize a new mutacin from S. mutans strain 29B, as it shows a promising activity spectrum against current human pathogens. Results Mutacin H-29B, produced by S. mutans strain 29B, was purified by successive hydrophobic chromatography from a liquid preparation consisting of cheese whey permeate (6% w/v supplemented with yeast extract (2% and CaCO3 (1%. Edman degradation revealed 24 amino acids identical to those of mutacin II (also known as J-T8. The molecular mass of the purified peptide was evaluated at 3246.08 ± 0.1 Da by MALDI-TOF MS. Conclusion A simple procedure for production and purification of mutacins along with its characterization is presented. Our results show that the amino acid sequence of mutacin H-29B is identical to the already known mutacin II (J-T8 over the first 24 residues. S. mutans strains of widely different origins may thus produce very similar bacteriocins.

Background It has been recognized that cells do not respond equally to ultraviolet (UV) radiation but it is not clear whether this is due to genetic, biochemical or structural differences of the cells. We have a novel cybrid (cytoplasmic hybrids) model that allows us to analyze the contribution of mitochondrial DNA (mtDNA) to cellular response after exposure to sub-lethal dose of UV. mtDNA can be classified into haplogroups as defined by accumulations of specific single nucleotide polymorphisms (SNPs). Recent studies have shown that J haplogroup is high risk for age-related macular degeneration while the H haplogroup is protective. This study investigates gene expression responses in J cybrids versus H cybrids after exposure to sub-lethal doses of UV-radiation. Methodology/Principal Findings Cybrids were created by fusing platelets isolated from subjects with either H (n = 3) or J (n = 3) haplogroups with mitochondria-free (Rho0) ARPE-19 cells. The H and J cybrids were cultured for 24 hours, treated with 10 mJ of UV-radiation and cultured for an additional 120 hours. Untreated and treated cybrids were analyzed for growth rates and gene expression profiles. The UV-treated and untreated J cybrids had higher growth rates compared to H cybrids. Before treatment, J cybrids showed lower expression levels for CFH, CD55, IL-33, TGF-A, EFEMP-1, RARA, BCL2L13 and BBC3. At 120 hours after UV-treatment, the J cybrids had decreased CFH, RARA and BBC3 levels but increased CD55, IL-33 and EFEMP-1 compared to UV-treated H cybrids. Conclusion/Significance In cells with identical nuclei, the cellular response to sub-lethal UV-radiation is mediated in part by the mtDNA haplogroup. This supports the hypothesis that differences in growth rates and expression levels of complement, inflammation and apoptosis genes may result from population-specific, hereditary SNP variations in mtDNA. Therefore, when analyzing UV-induced damage in tissues, the mtDNA haplogroup background may be

The reaction proceeds via a triangle mechanism, with {\\bar{{{B}}}}{{s}}0\\to {{J}}/{{\\psi }}{{{K}}}{{* }}\\bar{{{K}}}+{{c}}.{{c}}., followed by the decay K* → Kπ and a further fusion of {{K}}\\bar{{{K}}} into the {{{f}}}0(980) or a0(980). We show that the mechanism develops a singularity around the π0 f0(980) or π0 a0(980) invariant mass of 1420 MeV, where the π0 f0 and π0 a0 decay modes are magnified and also the ratio of π0 f0 to π0 a0 production. Using experimental information for the {\\bar{{{B}}}}{{s}}0\\to {{J}}/{{\\psi }}{{{K}}}{{* }}\\bar{{{K}}}+{{c}}.{{c}}. decay, we are able to obtain absolute values for the reactions studied which fall into the experimentally accessible range. The reactions proposed and the observables evaluated, when contrasted with actual experiments, should be very valuable to obtain information on the nature of the low lying scalar mesons.

J-integral flaw resistance curves of Incoloy 800H at room temperature

International Nuclear Information System (INIS)

Krompholz, K.; Ullrich, G.

1985-08-01

J-integral experiments at room temperature were performed on three point bend type specimens of the iron-nickel base alloy Incoloy 800H with a/w-ratios of 0.3 and 0.5. These experiments are performed within the frame of a round robin test in cooperation with German- and US-partners. The tests were performed in stroke control as well as in load control. Three different evaluation procedures were applied: -The signal of the dc potential drop technique -The partial unloading procedure and -The multiple specimen technique. Evaluating the dc potential drop technique and the multiple specimen method delivered reasonable results while the partial unloading procedure failed. The different methods are discussed and fractographic results support these results under discussion. (author)

We present a detailed analysis from new multi-wavelength observations of the exceptional galaxy cluster ACT-CL J0102-4915, likely the most massive, hottest, most X-ray luminous and brightest Sunyaev-Zel'dovich (SZ) effect cluster known at redshifts greater than 0.6. The Atacama Cosmology Telescope (ACT) collaboration discovered ACT-CL J0102-4915 as the most significant Sunyaev-Zeldovich (SZ) decrement in a sky survey area of 755 square degrees. Our VLT/FORS2 spectra of 89 member galaxies yield a cluster redshift, z = 0.870, and velocity dispersion, sigma(gal) +/- 1321 106 km s-1. Our Chandra observations reveal a hot and X-ray luminous system with an integrated temperature of T(X) = 14:5 +/- 0:1 keV and 0.5 2.0 keV band luminosity of L(X) = (2:19 0:11) 1045 h(exp -2)70erg s-1. We obtain several statistically consistent cluster mass estimates; using empirical mass scaling relations with velocity dispersion, X-ray Y(X) , and integrated SZ distortion, we estimate a cluster mass of M(200) = (2:16 +/- 0:32) 10(exp 15) h(exp-1) 70M compared to the Sun. We constrain the stellar content of the cluster to be less than 1% of the total mass, using Spitzer IRAC and optical imaging. The Chandra and VLT/FORS2 optical data also reveal that ACT-CL J0102-4915 is undergoing a major merger between components with a mass ratio of approximately 2 to 1. The X-ray data show significant temperature variations from a low of 6:6 +/- 0:7 keV at the merging low-entropy, high-metallicity, cool core to a high of 22 +/- 6 keV. We also see a wake in the X-ray surface brightness and deprojected gas density caused by the passage of one cluster through the other from which we estimate a merger speed of around 1300 km s(exp -1) for an assumed merger timescale of 1 Gyr. ACTCL J0102-4915 is possibly a high-redshift analog of the famous Bullet Cluster. Such a massive cluster at this redshift is rare, although consistent with the standard CDM cosmology in the lower part of its allowed mass range. Massive

We study the complete one-loop electroweak (EW) corrections to the processes of single charged Higgs boson production associated with a neutral Higgs boson (h 0 ,H 0 ,A 0 ) and a gauge boson W ± in the framework of the minimal supersymmetric standard model (MSSM). Numerical results at the SPS1a ' benchmark point as proposed in the SPA project, are presented for demonstration. We find that for the process e + e - →h 0 H ± W ± the EW relative correction can be either positive or negative and in the range of -15%∼20% in our chosen parameter space. While for the processes e + e - →H 0 (A 0 )H ± W ± the corrections generally reduce the Born cross sections and the EW relative corrections are typically of order -10%∼-20%
Measurement of CP violation in B{sup 0}→J/ψK{sup 0}{sub S} decays with the LHCb experiment

Energy Technology Data Exchange (ETDEWEB)

Wishahi, Julian Tarek

2013-12-19

This thesis presents the LHCb measurement of CP violation in decays of neutral B{sup 0} mesons and their anti-particles into the J/ψK{sup 0}{sub S} final state. The interference of the B{sup 0}- anti B{sup 0} mixing with the decay into the common final state leads to a decay time dependent decay rate asymmetry between B{sup 0} and anti B{sup 0} mesons. The CP observables, S{sub J/ψK{sup 0}{sub S}} and C{sub J/ψK{sup 0}{sub S}}, allow for a determination of the CKM angle β, which is one of the most precisely measured CP parameters of the Standard Model. Thus, B{sup 0}→J/ψK{sup 0}{sub S} represents an excellent reference channel for decay time dependent CP measurements at LHCb. The analysis is performed with a dataset that corresponds to 1 fb{sup -1} of pp collisions collected at a centre-of-mass energy of 7 TeV by the LHCb experiment at CERN. Using an unbinned maximum likelihood fit, the CP observables are measured as S{sub JψK{sup 0}{sub S}}=0.73±0.07(stat.)±0.04(syst.) and C{sub J/ψK{sup 0}{sub S}}=0.03±0.09(stat.)±0.01(syst.), leading to the world's best measurement of these observables at a hadron collider. Furthermore, these results are consistent with the averages of previous measurements and within expectations from the Standard Model.

Measurement of the polarisation amplitudes in $B^0 \\rightarrow J/\\psi K^{*}(892)^0$ decays with the LHCb experiment

Bien, Alexander; Schultz-Coulon, Hans-Christian

In this thesis a measurement of the polarisation amplitudes and the corresponding strong phases of the decay $B^0 \\rightarrow J/\\psi(\\mu^+\\mu^-) K^{*}(892)^0(K^+\\pi^-)$ is presented. Studying $B^0 \\rightarrow J/\\psi(\\mu^+\\mu^-) K^{*}(892)^0(K^+\\pi^-)$ and $\\overline{B}^0 \\rightarrow J/\\psi(\\mu^+\\mu^-) \\overline{K}^{*}(892)^0(K^-\\pi^+)$ decays separately allows for the measurement of direct CP violation. The Standard Model of particle physics does not predict any CP-violating processes for this decay channel. Thus, this analysis also serves as a search for new phenomena beyond the Standard Model. The measurement is performed using the full data sample collected with the LHCb detector in 2011 taken in proton-proton collisions at a centre-of-mass energy of $7$ TeV corresponding to an integrated luminosity of approximately $1.0$ fb$^{-1}$. The determination of the polarisation amplitudes requires an angular analysis of the final state particles to disentangle the three possible angular momentum states. The observ...

The LHCb experiment will study CP violation and rare B meson decays at the LHC accelerator, in the CERN laboratories of Geneva. The CP violation in the $b$ quark mesons was observed for the first time measuring the $\\sin2\\beta$ parameter. In the first year of data taking at LHCb the $\\sin2\\beta$ measurement will be performed in the channel $B_d ^0 \\rightarrow J/\\psi K_S ^0$ (called golden channel). The comparison with results obtained in previous experiments will show possible systematic errors. Once the systematic errors will be understood, the possible discrepancies with the expected results will be the sign of a new physics beyond the Standard Model. $\\sin2\\beta$ is extracted from the asymmetry in the decay $B_d ^0 \\rightarrow J/\\psi(\\mu^+\\mu^-) K_S ^0 (\\pi^+\\pi^-)$ and its CP conjugated $\\overline{B}_d ^0 \\rightarrow J/\\psi(\\mu^-\\mu^+) K_S ^0(\\pi^-\\pi^+)$. To distinguish between $B_d ^0$ and $\\overline{B}_d$ flavour tagging algorithms are used. These introduce an additional parameter: the wrong tag fracti...

The Photoloc technique has been employed to measure the state-resolved differential cross sections of the HD(v', j(')) product in the reaction H + D2 over a wide range of collision energies and internal states. The experimental results were compared with fully dimensional, time-dependent quantum mechanical calculations on the refined Boothroyd-Keogh-Martin-Peterson potential energy surface. We find nearly perfect agreement between theory and experiment for HD(v', j(')) product states with low to medium rotational excitation, e.g., HD(v' = 1, j(') = 3) at a collision energy, Ecoll, of 1.72 eV, HD(v' = 1, j(') = 3, 5) at Ecoll = 1.97 eV, and HD(v' = 3, j(') = 3) at Ecoll = 1.97 eV. As the rotational angular momentum, j('), of HD(v', j(')) increases, the agreement between theoretical predictions and experimental measurements worsens but not in a simple fashion. A moderate disagreement between theory and experiment has been found for HD(v' = 0, j(') = 12) at Ecoll = 1.76 eV and increased monotonically for HD(v' = 0, j(') = 13) at Ecoll = 1.74 eV, HD(v' = 0, j(') = 14) at Ecoll = 1.72 eV, and HD(v' = 0, j(') = 15) at Ecoll = 1.70 eV. Disagreement was not limited to vibrationless HD(v', j(')) product states: HD(v' = 1, j(') = 12) at Ecoll = 1.60 eV and HD(v' = 3, j(') = 8, 10) at Ecoll = 1.97 eV followed a similar trend. Theoretical calculations suggest more sideways∕forward scattering than has been observed experimentally for high j(') HD(v', j(')) states. The source of this discrepancy is presently unknown but might be the result of inaccuracy in the potential energy surface.

We present a detailed analysis from new multi-wavelength observations of the exceptional galaxy cluster ACT-CL J0102-4915, likely the most massive, hottest, most X-ray luminous and brightest Sunyaev-Zel'dovich (SZ) effect cluster known at redshifts greater than 0.6. The Atacama Cosmology Telescope (ACT) collaboration discovered ACT-CL J0102-4915 as the most significant Sunyaev-Zeldovich (SZ) decrement in a sky survey area of 755 square degrees. Our VLT/FORS2 spectra of 89 member galaxies yield a cluster redshift, z = 0.870, and velocity dispersion, sigma(sub gal) = 1321+/-106 km s-1. Our Chandra observations reveal a hot and X-ray luminous system with an integrated temperature of T(sub X) = 14.5+/-1.0 keV and 0.5-2.0 keV band luminosity of L(sub X) = (2.19+/-0.11)×10(sup 45) h(sup -2)(sub 70) erg s-1. We obtain several statistically consistent cluster mass estimates; using empirical mass scaling relations with velocity dispersion, X-ray Y(sub X), and integrated SZ distortion, we estimate a cluster mass of M(sub 200a) = (2.16+/-0.32)×1015 h(sup -1)(sub 70) solar mass. We constrain the stellar content of the cluster to be less than 1% of the total mass, using Spitzer IRAC and optical imaging. The Chandra and VLT/FORS2 optical data also reveal that ACT-CL J0102-4915 is undergoing a major merger between components with a mass ratio of approximately 2 to 1. The X-ray data show significant temperature variations from a low of 6.6+/-0.7 keV at the merging low-entropy, high-metallicity, cool core to a high of 22+/-6 keV. We also see a wake in the X-ray surface brightness and deprojected gas density caused by the passage of one cluster through the other. Archival radio data at 843 MHz reveal diffuse radio emission that, if associated with the cluster, indicates the presence of an intense double radio relic, hosted by the highest redshift cluster yet. ACT-CL J0102-4915 is possibly a high-redshift analog of the famous Bullet Cluster. Such a massive cluster at this redshift

Coulomb displacement energies of the T=1, J=0 states of A=42 nuclei

Sato, H.

1978-01-01

Coulomb displacement energies of the T=1, J=0 + and 6 1 + states of A=42 nuclei are analyzed with previously known charge dependent forces and effects, and with the available Hartree-Fock single-particle wave functions. From the study of the Coulomb displacement energies of the 6 1 + states it is found that the present knowledge on the charge dependence, including a phenomenological charge symmetry breaking force previously introduced so as to help explain the Nolen-Schiffer anomaly, gives a sufficient and consistent explanation for both single-particle and two-particle systems. From the study of the 0 + states, it is found that the Coulomb displacement energies of the second 0 2 + states can be explained with a compensation between the smaller Coulomb energies of the second lowest two-particle state and larger ones of the deformed 4p-2h state.

Measurements are presented of the $CP$ violation observables $S$ and $C$ in the decays of $B^0$ and $\\overline{B}{}^0$ mesons to the $J/\\psi K^0_S$ final state. The data sample corresponds to an integrated luminosity of $3.0\\,\\text{fb}^{-1}$ collected with the LHCb experiment in proton-proton collisions at center-of-mass energies of $7$ and $8\\,\\text{TeV}$. The analysis of the time evolution of $41500$ $B^0$ and $\\overline{B}{}^0$ decays yields $S = 0.731 \\pm 0.035 \\, \\text{(stat)} \\pm 0.020 \\,\\text{(syst)}$ and $C = -0.038 \\pm 0.032 \\, \\text{(stat)} \\pm 0.005\\,\\text{(syst)}$. In the Standard Model, $S$ equals $\\sin(2\\beta)$ to a good level of precision. The values are consistent with the current world averages and with the Standard Model expectations.

The cross sections of e + e - →hadrons, e + e - , μ + μ - have been measured in the vicinity of J/ψ resonance at BES/BEPC. The fit of the observed cross sections gives the new results of J/ψ resonance parameters: the partial widths to hadrons, electrons and muons are Γ h = 74.1 +- 8.1 keV, Γ e = 5.14 +- 0.39 keV and Γ μ = 5.13 +-0.52 keV respectively; the total width Γ = 84.4 +- 8.9 keV; the branching fractions Γ h /Γ = (87.8 +- 0.5)%, Γ e /Γ (6.09 +- 0.33)%, and Γ μ /Γ = (6.08 +- 0.33)%

Using the decay sequence J/ψ → γX,X → a 0 ± (980)π minus-plus , a 0 ± (980) → ηπ ± , where X is the f 1 (1285) or η(1400), the ηπ + vs ηπ - Dalitz plot intensity distributions are fitted with a model containing a coupled-channel parametrization of the a 0 (980). Preliminary values for the spin of X, the mass and width of the a 0 ± (980) to ηπ ± , and the ratio of a 0 + (980) coupling strengths, g K 2 /g η 2 , to bar K 0 K + and ηπ + are determined. From this model, the predictions for the ratios of branching ratios r X = B(X → a 0 (980)π)·B(a 0 (980) → K bar K)/B(X → a 0 ± (980)π)·B(a 0 ± (980) → ηπ ± ) are compared with those obtained from MARK III Partial Waves analyses of the decays J/ψ → γK s 0 K ± π minus-plus and J/ψ → γηπ + π - . 12 refs., 3 figs., 4 tabs
Modeling the emission of the galactic very high energy γ-ray sources G 1.9+0.3, G 330.2+1.0, HESS J1303-631 and PSR B1259-63/LS 2883 observed with H.E.S.S

Recently, imaging atmospheric Cherenkov telescopes (IACTs) have discovered numerous new sources representing various source classes in the very high energy (VHE; E>100 GeV) sky. This work presents studies of representatives of three types of Galactic VHE emitters: the Supernova remnants (SNRs) G1.9+0.3 and G330.2+1.0, the pulsar wind nebula (PWN) HESS J1303.631 and the binary system PSR B1259.63/LS 2883. The analysis of the H.E.S.S. data and the broadband emission modeling are presented. G1.9+0.3 and G330.2+1.0 are synchrotron-dominated SNRs whose non-thermal X-ray emission implies that intensive particle acceleration occurs at their shock fronts. This makes them promising candidates for the detection at VHEs. They were observed by the High Energy Stereoscopic System (H.E.S.S.) yielding no signs of significant VHE γ-ray emission from either SNR. The 99% confidence level upper limits on the TeV flux were determined. For an assumed spectral index of 2.5 the obtained upper limits are F G1.9 (>260 GeV) -13 cm -2 s -1 for G1.9+0.3 and F G330 (>380 GeV) -12 cm -2 s -1 for G330.2+1.0. Upper limits on the VHE emission provide constraints on the interior magnetic field in the context of a leptonic scenario and on the interstellar medium (ISM) density and cosmic-ray (CR) efficiency in a hadronic scenario. Lower limits on the interior magnetic fields were estimated at 15 μG for G1.9+0.3 and 14 μG for G330.2+1.0. In the case of the hadronic scenario, the H.E.S.S. upper limits are two orders of magnitude greater than the flux prediction. Obtained upper limits on the ISM densities are compatible with other estimates of the densities (from the thermal X-ray emission for G330.2+1.0 and from the expansion rate for G1.9+0.3). The CR efficiency cannot be constrained with the current H.E.S.S. upper limits. HESS J1303-631 is an initially unidentified H.E.S.S. source which was recently identified as a PWN associated with the pulsar PSR J1301-6305. The broadband emission of the source

Interpretation of CP violation measurements using charmonium decays, in both the B0 and Bs systems, can be subject to changes due to "penguin" type diagrams. These effects can be investigated using measurements of the Cabibbo-suppressed B0->J/\\psi pi+pi- decays. The final state composition of this channel is investigated using a 1.0/fb sample of data produced in 7 TeV pp collisions at the LHC and collected by the LHCb experiment. A modified Dalitz plot analysis is performed using both the invariant mass spectra and the decay angular distributions. An improved measurement of the B0->J/\\psi pi+pi- branching fraction of (3.97 +/-0.09+/- 0.11 +/- 0.16)x10^{-5} is reported where the first uncertainty is statistical, the second is systematic and the third is due to the uncertainty of the branching fraction of the decay B- -> J/\\psi K- used as a normalization channel. In the J/\\psi pi+pi- final state significant production of f0(500) and rho(770) resonances is found, both of which can be used for CP violation studie...

A study of $B^0$and $B^0_s$ meson decays into $J/\\psi\\eta$ and $J/\\psi\\eta^{\\prime}$ final states is performed using a data set of proton-proton collisions at centre-of-mass energies of 7 and 8TeV, collected by the LHCb experiment and corresponding to 3.0fb$^{-1}$ of integrated luminosity. The decay $B^0 \\rightarrow J/\\psi \\eta^{\\prime}$ is observed for the first time. The following ratios of branching fractions are measured: $ \\frac{\\mathcal{B}(B^0 \\rightarrow J/\\psi \\eta^{\\prime})}{\\mathcal{B}(B^0_s \\rightarrow J/\\psi \\eta^{\\prime})} = (2.28\\pm0.65\\,(stat)\\,\\pm0.10\\,(syst)\\,\\pm0.13\\,(f_{s}/f_{d}))\\times10^{-2},$ $ \\frac{\\mathcal{B}(B^0 \\rightarrow J/\\psi \\eta)}{\\mathcal{B}(B^0_s \\rightarrow J/\\psi \\eta)} = (1.85\\pm0.61\\,(stat)\\,\\pm0.09\\,(syst)\\,\\pm0.11\\,(f_{s}/f_{d}))\\times10^{-2},$ where the third uncertainty is related to the present knowledge of $f_{s}/f_{d}$, the ratio between the probabilities for a $b$ quark to form a $B^0_s$ or $B^0$ meson. The branching fraction ratios are used to determine the para...

Measurements are presented of the CP violation observables S and C in the decays of B(0) and Bover ¯]0 mesons to the J/ψK(S)(0) final state. The data sample corresponds to an integrated luminosity of 3.0 fb(-1) collected with the LHCb experiment in proton-proton collisions at center-of-mass energies of 7 and 8 TeV, and contains a total of 41 560 selected B^{0} and B[over ¯]^{0} decays. The analysis of the time evolution of these decays yields S=0.731±0.035(stat)±0.020(syst) and C=-0.038±0.032(stat)±0.005(syst). In the standard model, S equals sin(2β) to a good level of precision. The values are consistent with the current world averages and with the standard model expectations.

We study the anti B{sub s}{sup 0} → J/ψK{sup +}K{sup -}, anti B{sup 0} → J/ψK{sup +}K{sup -}, B{sup -} → J/ψK{sup 0}K{sup -}, anti B{sup 0} → J/ψπ{sup 0}η and B{sup -} → J/ψπ{sup -}η decays and compare their mass distributions with those obtained for the anti B{sub s}{sup 0} → J/ψπ{sup +}π{sup -} and anti B{sup 0} → J/ψπ{sup +}π{sup -}. The approach followed consist in a factorization of the weak part and the hadronization part into a factor which is common to all the processes. Then what makes the reactions different are some trivial Cabibbo-Kobayashi-Maskawa matrix elements and the weight by which the different pairs of mesons appear in a primary step plus their final state interaction. These elements are part of the theory and thus, up to a global normalization factor, all the invariant mass distributions are predicted with no free parameters. Comparison is made with the limited experimental information available. Further comparison of these results with coming LHCb measurements will be very valuable to make progress in our understanding of the meson.meson interaction and the nature of the low lying scalar meson resonances, f{sub 0}(500), f{sub 0}(980) and a{sub 0}(980).

The first measurement of ${C\\!P}$ asymmetries in the decay ${B_s^0\\to J/\\psi \\overline{K}^{*}(892)^{0}}$ and an updated measurement of its branching fraction and polarisation fractions are presented. The results are obtained using data corresponding to an integrated luminosity of $3.0\\,fb^{-1}$ of proton-proton collisions recorded with the LHCb detector at centre-of-mass energies of $7$ and $8\\,\\mathrm{TeV}$. Together with constraints from ${B^0\\to J/\\psi \\rho^0}$, the results are used to constrain additional contributions due to penguin diagrams in the ${C\\!P}$-violating phase ${{\\phi}_{s}}$, measured through ${B_s^0}$ decays to charmonium.
Influence of Ce-H bonding on the physical properties of the hydrides CeCoSiH1.0 and CeCoGeH1.0

2006-01-01

The hydrides CeCoSiH 1.0 and CeCoGeH 1.0 which crystallize like the parent antiferromagnetic compounds CeCoSi and CeCoGe in the tetragonal CeFeSi-type structure, have been investigated by specific heat and thermoelectric power measurements and 1 H nuclear magnetic resonance (NMR). CeCoSiH 1.0 is an intermediate valence compound whereas CeCoGeH 1.0 can be considered as a nearly trivalent cerium compound. This behaviour is corroborated by the occurrence of a slight broadening of the 1 H NMR signal in the sequence CeCoSiH 1.0 → CeCoGeH 1.0 . The band structure calculations performed on these hydrides reveal the existence of strong bonding Ce-H interaction, found to be larger in CeCoSiH 1.0 than in CeCoGeH 1.0
Measurement of the $\\Lambda^0_b$ lifetime in the exclusive decay $\\Lambda^0_b \\rightarrow J/\\psi \\Lambda^0$ with the \\D0~detector

In this work we report a measurement of the Λ⁰_b baryon lifetime using the exclusive decay Λ⁰_b→ J/ ΨΛ⁰. The B⁰ meson lifetime is also measured in the topologically similar channel B⁰→ J/ K⁰_S , which provides a crosscheck of the measurement procedure, and allows a direct determination of the ratio of the Λ⁰_b and the B⁰ lifetimes. The data used in this analysis were collected with the DØ detector during the complete Run II of the Fermilab Tevatron Collider, from 2002 to 2011, and correspond to an integrated luminosity of 10.4 fb^-1 of proton-antiproton collisions at a center of mass energy √s = 1.96 TeV. We obtain τ (Λ⁰_b ) = 1.303 ± 0.075 (stat.) ± 0.035 (syst.) ps, τ (B⁰) = 1.508±0.025 (stat.)±0.043 (syst.) ps and τ (Λ⁰_b )/τ (B⁰) = 0.864± 0.052 (stat.)±0.033 (syst.). These measurements supersede previous results of the DØ Collaboration using the same decay channels. Our measurement of the lifetime ratio is in excellent agreement with theoretical predictions and compatible with the current world-average, but differs with the latest measurement of the CDF Collaboration in more than 2 standard deviations.

The Mathematical Works of J. H. C. Whitehead, Volume 1: Differential Geometry contains all of Whitehead's published work on differential geometry, along with some papers on algebras. Most of these were written in the period 1929-1937, but a few later articles are included. The book begins with a list of Whitehead's works, in chronological order of writing as well as a biographical note by M. H. A. Newman and Barbara Whitehead, and a mathematical appreciation by John Milnor. This is followed by separate chapters on topics such as linear connections; a method of obtaining normal representations

We present a detailed analysis from new multi-wavelength observations of the exceptional galaxy cluster ACT-CL J0102–4915, likely the most massive, hottest, most X-ray luminous and brightest Sunyaev-Zel'dovich (SZ) effect cluster known at redshifts greater than 0.6. The Atacama Cosmology Telescope (ACT) collaboration discovered ACT-CL J0102–4915 as the most significant SZ decrement in a sky survey area of 755 deg 2 . Our Very Large Telescope (VLT)/FORS2 spectra of 89 member galaxies yield a cluster redshift, z = 0.870, and velocity dispersion, σ gal = 1321 ± 106 km s –1 . Our Chandra observations reveal a hot and X-ray luminous system with an integrated temperature of T X = 14.5 ± 0.1 keV and 0.5-2.0 keV band luminosity of L X = (2.19 ± 0.11) × 10 45 h –2 70 erg s –1 . We obtain several statistically consistent cluster mass estimates; using empirical mass scaling relations with velocity dispersion, X-ray Y X , and integrated SZ distortion, we estimate a cluster mass of M 200a = (2.16 ± 0.32) × 10 15 h –1 70 M ☉ . We constrain the stellar content of the cluster to be less than 1% of the total mass, using Spitzer IRAC and optical imaging. The Chandra and VLT/FORS2 optical data also reveal that ACT-CL J0102–4915 is undergoing a major merger between components with a mass ratio of approximately 2 to 1. The X-ray data show significant temperature variations from a low of 6.6 ± 0.7 keV at the merging low-entropy, high-metallicity, cool core to a high of 22 ± 6 keV. We also see a wake in the X-ray surface brightness and deprojected gas density caused by the passage of one cluster through the other. Archival radio data at 843 MHz reveal diffuse radio emission that, if associated with the cluster, indicates the presence of an intense double radio relic, hosted by the highest redshift cluster yet. ACT-CL J0102–4915 is possibly a high-redshift analog of the famous Bullet cluster. Such a massive cluster at this redshift is rare, although consistent

Measurement of mixing induced CP violation in $\\bar{B}^0_s$ decays is of prime importance in probing new physics. So far only the channel $\\bar{B}^0_s \\to J/\\psi\\phi$ has been used. Here we investigate $\\bar{B}^0_s $ decays into CP eigenstates and other modes in the $J/\\psi \\pi^+\\pi^-$ and $J/\\psi K^+ K^-$ final states. The $\\pi^+\\pi^-$mass spectrum has a relatively narrow structure peaking near 980 MeV first found by LHCb, that we identify as the $f_0(980)$, and show that it is consistent with being pure S-wave. Thus, this is a CP-odd eigenstate. The ratio of rates for $J/\\psi f_0(980)$ to $J/\\psi \\phi$, with $f_0(980)\\to\\pi^+\\pi^-$ in a $\\pm$90 MeV mass window around the $f_0(980)$ and $\\phi\\to K^+K^-$ is $R^{f_0}_{\\rm effective}=(21.7\\pm1.1\\pm$0.7)%. Other structures at higher mass are shown to contain D-wave. The $K^+K^-$ spectrum besides a large $\\phi$ component has significant $f'_2(1525)$.

Modeling the emission of the galactic very high energy {gamma}-ray sources G 1.9+0.3, G 330.2+1.0, HESS J1303-631 and PSR B1259-63/LS 2883 observed with H.E.S.S

Recently, imaging atmospheric Cherenkov telescopes (IACTs) have discovered numerous new sources representing various source classes in the very high energy (VHE; E>100 GeV) sky. This work presents studies of representatives of three types of Galactic VHE emitters: the Supernova remnants (SNRs) G1.9+0.3 and G330.2+1.0, the pulsar wind nebula (PWN) HESS J1303.631 and the binary system PSR B1259.63/LS 2883. The analysis of the H.E.S.S. data and the broadband emission modeling are presented. G1.9+0.3 and G330.2+1.0 are synchrotron-dominated SNRs whose non-thermal X-ray emission implies that intensive particle acceleration occurs at their shock fronts. This makes them promising candidates for the detection at VHEs. They were observed by the High Energy Stereoscopic System (H.E.S.S.) yielding no signs of significant VHE {gamma}-ray emission from either SNR. The 99% confidence level upper limits on the TeV flux were determined. For an assumed spectral index of 2.5 the obtained upper limits are F{sub G1.9}(>260 GeV)<4.6 x 10{sup -13} cm{sup -2}s{sup -1} for G1.9+0.3 and F{sub G330}(>380 GeV)<1.6 x 10{sup -12} cm{sup -2}s{sup -1} for G330.2+1.0. Upper limits on the VHE emission provide constraints on the interior magnetic field in the context of a leptonic scenario and on the interstellar medium (ISM) density and cosmic-ray (CR) efficiency in a hadronic scenario. Lower limits on the interior magnetic fields were estimated at 15 {mu}G for G1.9+0.3 and 14 {mu}G for G330.2+1.0. In the case of the hadronic scenario, the H.E.S.S. upper limits are two orders of magnitude greater than the flux prediction. Obtained upper limits on the ISM densities are compatible with other estimates of the densities (from the thermal X-ray emission for G330.2+1.0 and from the expansion rate for G1.9+0.3). The CR efficiency cannot be constrained with the current H.E.S.S. upper limits. HESS J1303-631 is an initially unidentified H.E.S.S. source which was recently identified as a PWN associated with

We report detections of three z ∼ 2.5 submillimeter-selected galaxies (SMGs; SMM J14011+0252, SMM J14009+0252, SMM J04431+0210) in the lowest rotational transition of the carbon monoxide molecule (CO J = 1-0) and one nondetection (SMM J04433+0210). For the three galaxies we detected, we find a line-integrated brightness temperature ratio of the J = 3-2 and 1-0 lines of 0.68 ± 0.08; the 1-0 line is stronger than predicted by the frequent assumption of equal brightnesses in the two lines and by most single-component models. The observed ratio suggests that mass estimates for SMGs based on J = 3-2 observations and J = 1-0 column density or mass conversion factors are low by a factor of 1.5. Comparison of the 1-0 line intensities with intensities of higher-J transitions indicates that single-component models for the interstellar media in SMGs are incomplete. The small dispersion in the ratio, along with published detections of CO lines with J upper >3 in most of the sources, indicates that the emission is from multi-component interstellar media with physical structures common to many classes of galaxies. This result tends to rule out the lowest scaling factors between CO luminosity and molecular gas mass, and further increases molecular mass estimates calibrated against observations of galaxies in the local universe. We also describe and demonstrate a statistically sound method for finding weak lines in broadband spectra that will find application in searches for molecular lines from sources at unknown redshifts.

We perform a comprehensive cosmological study of the H {sub 0} tension between the direct local measurement and the model-dependent value inferred from the Cosmic Microwave Background. With the recent measurement of H {sub 0} this tension has raised to more than 3 σ. We consider changes in the early time physics without modifying the late time cosmology. We also reconstruct the late time expansion history in a model independent way with minimal assumptions using distance measurements from Baryon Acoustic Oscillations and Type Ia Supernovae, finding that at z < 0.6 the recovered shape of the expansion history is less than 5% different than that of a standard ΛCDM model. These probes also provide a model insensitive constraint on the low-redshift standard ruler, measuring directly the combination r {sub s} h where H {sub 0} = h × 100 Mpc{sup −1}km/s and r {sub s} is the sound horizon at radiation drag (the standard ruler), traditionally constrained by CMB observations. Thus r {sub s} and H {sub 0} provide absolute scales for distance measurements (anchors) at opposite ends of the observable Universe. We calibrate the cosmic distance ladder and obtain a model-independent determination of the standard ruler for acoustic scale, r {sub s}. The tension in H {sub 0} reflects a mismatch between our determination of r {sub s} and its standard, CMB-inferred value. Without including high-ℓ Planck CMB polarization data (i.e., only considering the ''recommended baseline' low-ℓ polarisation and temperature and the high ℓ temperature data), a modification of the early-time physics to include a component of dark radiation with an effective number of species around 0.4 would reconcile the CMB-inferred constraints, and the local H {sub 0} and standard ruler determinations. The inclusion of the ''preliminary' high-ℓ Planck CMB polarisation data disfavours this solution.

The Zeeman tuning of the P(1)(0) line (nu=17 568.35 cm(-1)) of the A (7)Pi-X (7)Sigma(+) (0,0) band of manganese monohydride, MnH, has been investigated. The laser induced fluorescence spectrum of a supersonic molecular beam sample was recorded at a resolution of approximately 40 MHz and with field strengths of up to 362.0 mT. The observed spectrum was successfully fitted using a traditional effective Zeeman Hamiltonian to determine an effective magnetic g-factor for the J=2 level of the F(1)-spin component of the A (7)Pi(v=0) state. Spectral predictions of the P(1)(0) line at field strengths used in magnetic trapping experiments are presented.

Measurement of the Average $B^{0}_{s}$ Lifetime in the Decay $B^{0}_{s} \\to J/\\Psi\\Phi$

The lifetime difference between the long (CP odd) and short (CP even) lived components of the Bg meson is currently predicted to be of the order of 10 % in the Standard Model. It has been suggested that the decay Bg —>• J/\\|> 4) is predominantly CP even and thus the measured average lifetime could be shorter than the lifetime measured in the inclusive decay modes. We present a measurement of the average lifetime of the 6° meson in its decay Eg —>• J/4> cj), with J/\\|) —> M.+ M.~ and cj) —>• K+K-. During January 2002 and August 2003 the CDF experiment at the Tevatron has been exposed to about 135 pb" 1 of pp collisions with a centre-of-mass energy of A/S = 1.96 TeV. In the data sample collected with the J/\\Jj dimuon trigger we fully reconstruct about 125 Bg —> J/\\J) (J) candidates with precision silicon information. This is currently the largest exclusive Bg sample. We perform a fit to the proper decay time information to extract the average Bg lifetime and simultaneously use the mass information to disentangle signal from background. For cross-checks we measure the lifetime in the higher statistics modes Bj -» J/\\J> K* and B° —> J/4> K*°, which both have similar decay topologies and kinematics. We obtain r(B°s -> J/\\|> cf>) = (1.31±5:l3(stat.) ± 0.02(syst.)) ps , which is currently the best single measurement of the Bg lifetime and is consistent with other measurements. This result is not accurate enough to establish the existence of a possible significant lifetime difference between the CP odd and even states.

A full amplitude analysis of $\\Lambda_b^0 \\to J/\\psi p \\pi^-$ decays is performed with a data sample acquired with the LHCb detector from 7 and 8 TeV $pp$ collisions, corresponding to an integrated luminosity of 3 fb$^{-1}$. A significantly better description of the data is achieved when, in addition to the previously observed nucleon excitations $N\\to p\\pi^-$, either the $P_c(4380)^+$ and $P_c(4450)^+\\to J/\\psi p$ states, previously observed in $\\Lambda_b^0 \\to J/\\psi p K^-$ decays, or the $Z_c(4200)^-\\to J/\\psi \\pi^-$ state, previously reported in $B^0 \\to J/\\psi K^+ \\pi^-$ decays, or all three, are included in the amplitude models. The data support a model containing all three exotic states, with a significance of more than three standard deviations. Within uncertainties, the data are consistent with the $P_c(4380)^+$ and $P_c(4450)^+$ production rates expected from their previous observation taking account of Cabibbo suppression.

The even parity 4pnp J=0, 1, 2 doubly excited autoionizing states of neutral calcium in an atomic beam are investigated by a two-step isolated core excitation (ICE) method using two different combinations of polarization of the laser beams. The different excited energy levels are assigned to nine autoionizing Rydberg series 4p 1/2,3/2 np J=0, 1, 2 for 8≤n≤22. The theoretical interpretation is achieved by a combination of the eigenchannel R-matrix theory and the multichannel quantum defect (MQDT) method. Two, five and six closed interacting channels are introduced for the J=0, J=1 and J=2 series respectively. Theoretical energy level positions, autoionization widths and excitation profiles are compared with the experimental data, confirming the identification of the observed structures and providing evidence of extended mixing between the 4p 1/2 np and 4p 3/2 np series.

This paper presents an ultra low-power and low-voltage pulse-width modulation based ratiometric capacitive sensor interface. The interface was designed and fabricated in a standard 90 nm CMOS 1P9M technology. The measurements show an effective resolution of 10 bits using 0.5 V of supply voltage. The active occupied area is only 0.0045 mm2 and the Figure of Merit (FOM), which takes into account the energy required per conversion bit, is 0.43 pJ/bit. Furthermore, the results show low sensitivity to PVT variations due to the proposed ratiometric architecture. In addition, the sensor interface was connected to a commercial pressure transducer and the measurements of the resulting complete pressure sensor show a FOM of 0.226 pJ/bit with an effective linear resolution of 7.64 bits. The results validate the use of the proposed interface as part of a pressure sensor, and its low-power and low-voltage characteristics make it suitable for wireless sensor networks and low power consumer electronics.

Within the Standard Model, the decay $B^0_s\\to J/\\psi \\phi$, can occur via two main processes: the predominant tree and the sub-leading penguin. Penguin contributions have been so far ignored. Controlling them is crucial in order to disentangle Standard Model effects from possible New Physics in the measurement of $\\phi_s$. We studied the $B^0_s\\to J / \\psi
Characteristic Lifetime Of A Polarized Feature In The V=0, J=1-0 Sio Maser VY Canis Majoris

A time series cross correlation analysis has been developed for calculating the characteristic lifetime of linearly polarized features in the spectrum of silicon monoxide masers. Our observations of VY CMa in the v=0, J=1→0; transition from June 2003 to March 2006 revealed a highly linearly polarized feature at Vlsr=18.5 km s-1. Applying the cross correlation to this feature gave a characteristic lifetime of 2800 days. This time is much longer than the v=1, J=2→1; transition's lifetime of 645 days and indicates that the two transitions occur under different physical conditions. This research was supported by the University of Minnesota and the University of Minnesota, Morris.

We present a detailed analysis from new multi-wavelength observations of the exceptional galaxy cluster ACT-CL J0102-4915, likely the most massive, hottest, most X-ray luminous and brightest Sunyaev-Zel'dovich (SZ) effect cluster known at redshifts greater than 0.6. The Atacama Cosmology Telescope (ACT) collaboration discovered ACT-CL J0102-4915 as the most significant SZ decrement in a sky survey area of 755 deg{sup 2}. Our Very Large Telescope (VLT)/FORS2 spectra of 89 member galaxies yield a cluster redshift, z = 0.870, and velocity dispersion, {sigma}{sub gal} = 1321 {+-} 106 km s{sup -1}. Our Chandra observations reveal a hot and X-ray luminous system with an integrated temperature of T{sub X} = 14.5 {+-} 0.1 keV and 0.5-2.0 keV band luminosity of L{sub X} = (2.19 {+-} 0.11) Multiplication-Sign 10{sup 45} h{sup -2}{sub 70} erg s{sup -1}. We obtain several statistically consistent cluster mass estimates; using empirical mass scaling relations with velocity dispersion, X-ray Y{sub X}, and integrated SZ distortion, we estimate a cluster mass of M{sub 200a} = (2.16 {+-} 0.32) Multiplication-Sign 10{sup 15} h{sup -1}{sub 70} M{sub Sun }. We constrain the stellar content of the cluster to be less than 1% of the total mass, using Spitzer IRAC and optical imaging. The Chandra and VLT/FORS2 optical data also reveal that ACT-CL J0102-4915 is undergoing a major merger between components with a mass ratio of approximately 2 to 1. The X-ray data show significant temperature variations from a low of 6.6 {+-} 0.7 keV at the merging low-entropy, high-metallicity, cool core to a high of 22 {+-} 6 keV. We also see a wake in the X-ray surface brightness and deprojected gas density caused by the passage of one cluster through the other. Archival radio data at 843 MHz reveal diffuse radio emission that, if associated with the cluster, indicates the presence of an intense double radio relic, hosted by the highest redshift cluster yet. ACT-CL J0102-4915 is possibly a high

Using the data samples of (1310.6 ±7.2 )×106 J /ψ events and (448.1 ±2.9 )×106 ψ (3686 ) events collected with the BESIII detector, we search for the rare decays J /ψ →D0e+e-+c .c . and ψ (3686 )→D0e+e-+c .c . No significant signals are observed and the corresponding upper limits on the branching fractions at the 90% confidence level are determined to be B (J /ψ →D0e+e-+c .c .)<8.5 ×10-8 and B (ψ (3686 )→D0e+e-+c .c .)<1.4 ×10-7 , respectively. Our limit on B (J /ψ →D0e+e-+c .c .) is more stringent by 2 orders of magnitude than the previous results, and B (ψ (3686 )→D0e+e-+c .c .) is measured for the first time.

The nonlinear magneto-optical rotation in a medium consisting of J=1→J=0 atoms placed in a static magnetic field is studied. The density matrix approach and irreducible atomic basis are used to describe the state of the atomic system. The stationary propagation equations for two collinear laser beams with perpendicular circular polarizations are derived and analyzed in the case of the magnetic field perpendicular to the light propagation direction. The effect of the linear polarization rotation toward the direction parallel or perpendicular to the magnetic field vector and lossless propagation of the resulting light are predicted. The conversion of the circularly polarized beam into linearly polarized one is shown. The propagation of the leading edges of switched on cw-laser beams and their stationary propagation are analyzed numerically. The dependence of the considered effects on the light detuning and on the additional magnetic field component parallel to the light propagation direction is discussed. The destructive role of the collisional relaxation is demonstrated

A full amplitude analysis of Λ_{b}^{0}→J/ψpπ^{-} decays is performed with a data sample acquired with the LHCb detector from 7 and 8 TeV pp collisions, corresponding to an integrated luminosity of 3 fb^{-1}. A significantly better description of the data is achieved when, in addition to the previously observed nucleon excitations N→pπ^{-}, either the P_{c}(4380)^{+} and P_{c}(4450)^{+}→J/ψp states, previously observed in Λ_{b}^{0}→J/ψpK^{-} decays, or the Z_{c}(4200)^{-}→J/ψπ^{-} state, previously reported in B^{0}→J/ψK^{+}π^{-} decays, or all three, are included in the amplitude models. The data support a model containing all three exotic states, with a significance of more than three standard deviations. Within uncertainties, the data are consistent with the P_{c}(4380)^{+} and P_{c}(4450)^{+} production rates expected from their previous observation taking account of Cabibbo suppression.

The product of the $\\Lambda_b^0$ ($\\overline{B}^0$) differential production cross-section and the branching fraction of the decay $\\Lambda_b^0\\rightarrow J/\\psi pK^-$ ($\\overline{B}^0\\rightarrow J/\\psi\\overline{K}^*(892)^0$) is measured as a function of the beauty hadron transverse momentum, $p_{\\rm T}$, and rapidity, $y$. The kinematic region of the measurements is $p_{\\rm T}<20~{\\rm GeV}/c$ and $2.0 < y < 4.5$. The measurements use a data sample corresponding to an integrated luminosity of $3~{\\rm fb}^{-1}$ collected by the LHCb detector in $pp$ collisions at centre-of-mass energies $\\sqrt{s}=7~{\\rm TeV}$ in 2011 and $\\sqrt{s}=8~{\\rm TeV}$ in 2012. Based on previous LHCb results of the fragmentation fraction ratio, $f_{\\Lambda_B^0}/f_d$, the branching fraction of the decay $\\Lambda_b^0\\rightarrow J/\\psi pK^-$ is measured to be \\begin{equation*} \\mathcal{B}(\\Lambda_b^0\\rightarrow J/\\psi pK^-)= (3.04\\pm0.04\\pm0.06\\pm0.33^{+0.43}_{-0.27})\\times10^{-4}, \\end{equation*} where the first uncertainty is st...
A study of time-dependent CP-violating asymmetries in B0->J/psiK0S and B0->psi(2S)K0S decays

Energy Technology Data Exchange (ETDEWEB)

Barrera, Barbara

2000-10-16

We present a preliminary measurement of time-dependent CP-violating asymmetries in B{sup 0} {yields} J/{psi} K{sub S}{sup 0} and B{sup 0} {yields} {psi}(2S)K{sub S}{sup 0} decays recorded by the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. The data sample consists of 9.0 fb{sup -1} collected at the {Upsilon}(4S) resonance and 0.8 fb{sup -1} off-resonance. One of the neutral B mesons, produced in pairs at the {Upsilon}(4S), is fully reconstructed. The flavor of the other neutral B meson is tagged at the time of its decay, mainly with the charge of identified leptons and kaons. A neural network tagging algorithm is used to recover events without a clear lepton or kaon tag. The time difference between the decays is determined by measuring the distance between the decay vertices. Wrong-tag probabilities and the time resolution function are measured with samples of fully-reconstructed semileptonic and hadronic neutral B final states. The value of the asymmetry amplitude, sin2{beta}, is determined from a maximum likelihood fit to the time distribution of 120 tagged B{sup 0} {yields} J/{psi} K{sub S}{sup 0} and B{sup 0} {yields} {psi}(2S) K{sub S}{sup 0} candidates to be sin2{beta} = 0.12 {+-} 0.37(stat) {+-} 0.09(syst) (preliminary).
Lorentz laser-assisted stripping (Lolas) for H-/H0 injection into proton drivers

International Nuclear Information System (INIS)

Gastaldi, Ugo

2002-01-01

We discuss the main components of schemes for Lorentz laser-assisted stripping (abbreviated Lolas henceforth) proposed for injection into proton driver accumulators: H- → H0 + e- Lorentz stripping, H0→H0(n) laser excitation, H0(n)→p+ + e- Lorentz stripping. We mention results obtained in practice of H- beam transport and storage and of experiments addressing physics of the H- ion, of the H0 atom and of vacuum, which prove the feasibility of each Lolas component. For high enough injection energies, it is feasible to split without losses the H0 beam sent towards the accumulator into a fraction stripped to p+s and stored inside the accumulator and a complementary fraction of H0s delivered to high duty-cycle users. The fraction of stored beam can exceed 50% with one single Fabry-Perot cavity used to enhance the laser power density. Aspects of Lolas integration and optimization are pointed out

A spin precessor using H - to H 0 stripping, followed by small precession magnets, has been developed for the LAMPF 800-MeV polarized H - beam. The performance of the system was studied with the computer code documented in this report. The report starts from the fundamental physics of a system of spins with hyperfine coupling in a magnetic field and contains many examples of beam behavior as calculated by the program
Study of B0→J/ψD(*) and ηcD(*) in perturbative QCD

International Nuclear Information System (INIS)

Eilam, Gad; Ladisa, Massimo; Yang Yadong

2002-01-01

Motivated by recent interest in soft J/ψ production in B decays, we investigate B 0 →J/ψ D ( * ) and η c D ( * ) decays in perturbative QCD. We find that, within that framework, these decays are calculable since the heavy cc(bar sign) pair in the final states is created by a hard gluon. The branching ratios are estimated to be around 10 -7 -10 -8 , too small to be consistent with the data, suggesting that other mechanism(s) contribute to the observed excess of soft J/ψ in B 0 →J/ψ+X decays. The possibility of the production of a hybrid sd(bar sign)g meson with a mass of about 2 GeV is briefly entertained

Measurement of mixing-induced CP violation in B{sup Macron }{sub s}{sup 0} decays is of prime importance in probing new physics. So far only the channel B{sup Macron }{sub s}{sup 0}{yields}J/{psi}{phi} has been used. Here we report on a measurement using an LHCb data sample of 0.41 fb{sup -1}, in the CP odd eigenstate J/{psi}f{sub 0}(980), where f{sub 0}(980){yields}{pi}{sup +}{pi}{sup -}. A time-dependent fit of the data with the B{sup Macron }{sub s}{sup 0} lifetime and the difference in widths of the heavy and light eigenstates constrained to the values obtained from B{sup Macron }{sub s}{sup 0}{yields}J/{psi}{phi} yields a value of the CP violating phase of -0.44{+-}0.44{+-}0.02 rad, consistent with the Standard Model expectation.
Generation of the J/sub c/, H/sub c/, T/sub c/ surface for commercial superconductor using reduced-state parameters

International Nuclear Information System (INIS)

Green, M.A.

1988-04-01

This report presents a method for calculating the J/sub C/, H/sub C/, T/sub C/ surface for Type II Superconductors. The method requires that one knows T/sub C/ at zero current and field, H/sub c2/ at zero current and temperature, and J/sub c/ at at least one temperature and field. The theory presented in this report agrees with the measured data quite well over virtually the entire J/sub c/, H/sub c/, T/sub c/ surface given the value of J/sub c/ versus H at one or two temperatures. This report presents calculated and measured values of J/sub c/ versus T and B for niobium titanium, niobium zirconium, niobium tin, niobium titanium tin, niobium tantalum tin, vanadium zirconium hafnium, and vanadium gallium. Good agreement of theory with measured data was obtained for commercial niobium titanium and niobium tin. 76 refs., 26 figs., 6 tabs

The decay $B^0_s \\to J/\\psi\\pi^+\\pi^-$ can be exploited to study $CP$ violation. A detailed understanding of its structure is imperative in order to optimize its usefulness. An analysis of this three-body final state is performed using a 1.0 fb$^{-1}$ sample of data produced in 7 TeV $pp$ collisions at the LHC and collected by the LHCb experiment. A modified Dalitz plot analysis of the final state is performed using both the invariant mass spectra and the decay angular distributions. The $\\pi^+\\pi^-$ system is shown to be dominantly in an S-wave state, and the $CP$-odd fraction in this $B^0_s$ decay is shown to be greater than 0.977 at 95\\% confidence level. In addition, we report the first measurement of the $J/\\psi\\pi^+\\pi^-$ branching fraction relative to $J/\\psi\\phi$ of $(21.28 \\pm 0.51 \\pm 0.56)\\%$.

The A7Π- X7Σ + (0, 0) band of MnH at 568 nm has been recorded by laser fluorescence excitation spectroscopy. The original rotational analysis of Nevin [ Proc. R. Irish Acad.48A, 1-45 (1942); 50A, 123-137 (1945)] has been extended with some corrections at low J. Systematic internal hyperfine perturbations in the X7Σ + state, caused by the Δ N = 0, Δ J = ±1 matrix elements of the 55Mn hyperfine term in the Hamiltonian, have been observed in all seven electron spin components over the entire range of N″ studied. These perturbations destroy the "goodness" of J″ as a quantum number, giving rise to hyperfine-induced Δ J = ±2 rotational branches and to observable energy shifts of the most severely affected levels. The A7Π state, with A = 40.5 cm -1 and B = 6.35 cm -1, evolves rapidly from Hund's case ( a) to case ( b) coupling, which produces anomalous branch patterns at low J. A total of 156 rotational branches have been identified and fitted by least squares to an effective Hamiltonian, providing precise values for the rotational and fine structure constants. Values of the principal constants determined in the fit are (1σ errors in units of the last digit are listed in parentheses): The fine structures of the A7Π and X7Σ + states confirm the assignment of the A ← X transition as Mn 4 pπ ← 4 sσ in the presence of a spectator, nonbonding Mn 3 d5 ( 6S) open core.

We present 0.9-2.5 μm resolved spectra for the ultracool binary WISEPC J121756.91+162640.2AB. The system consists of a pair of brown dwarfs that straddles the currently defined T/Y spectral type boundary. We use synthetic spectra generated by model atmospheres that include chloride and sulfide clouds (Morley et al.), the distance to the system (Dupuy and Kraus), and the radius of each component based on evolutionary models (Saumon and Marley) to determine a probable range of physical properties for the binary. The effective temperature of the T8.5 primary is 550-600 K and that of the Y0-Y0.5 secondary is ≈450 K. The atmospheres of both components are either free of clouds or have extremely thin cloud layers. We find that the masses of the primary and secondary are 30 and 22 M {sub Jup}, respectively, and that the age of the system is 4-8 Gyr. This age is consistent with astrometric measurements (Dupuy and Kraus) that show that the system has kinematics intermediate between those of the thin and thick disks of the Galaxy. An older age is also consistent with an indication by the H – K colors that the system is slightly metal poor.

We present new near-infrared spectra, obtained at Gemini Observatory, for two Y dwarfs: WISE J035000.32-565830.2 (W0350) and WISEP J173835.52+273258.9 (W1738). A FLAMINGOS-2 R = 540 spectrum was obtained for W0350, covering 1.0 < ? micrometer < 1.7, and a cross-dispersed GNIRS R = 2800 spectrum was obtained for W1738, covering 0.993 - 1.087 micrometer, 1.191 - 1.305 micrometer, 1.589 - 1.631 micrometer, and 1.985 - 2.175 micrometer, in four orders. We also present revised Y JH photometry for W1738, using new NIRI Y and J imaging, and a re-analysis of the previously published NIRI H band images. We compare these data, together with previously published data for late-T and Y dwarfs, to cloud-free models of solar metallicity, calculated both in chemical equilibrium and with disequilibrium driven by vertical transport. We find that for the Y dwarfs the non-equilibrium models reproduce the near-infrared data better than the equilibrium models. The remaining discrepancies suggest that fine-tuning the CH4/CO and NH3/N2 balance is needed. Improved trigonometric parallaxes would improve the analysis. Despite the uncertainties and discrepancies, the models reproduce the observed near-infrared spectra well. We find that for the Y0, W1738, T(sub eff) = 425 +/- 25K and log g = 4.0 +/- 0.25, and for the Y1, W0350, T(sub eff) = 350 +/- 25K and log g = 4.0 +/- 0.25. W1738 may be metal-rich. Based on evolutionary models, these temperatures and gravities correspond to a mass range for both Y dwarfs of 3 - 9 Jupiter masses, with W0350 being a cooler, slightly older, version of W1738; the age of W0350 is 0.3 - 3 Gyr, and the age of W1738 is 0.15 - 1 Gyr.

Histone H1(0) mapping using monoclonal antibodies.

Dousson, S; Gorka, C; Gilly, C; Lawrence, J J

1989-06-01

Monoclonal antibodies (mAb) to ox liver histone H1 degree were produced and characterized. Two sets of mice were immunized either with pure H1(0) or with an H1(0)-yeast tRNA complex. Eleven hybridomas of various clonal origin were selected. Typing of the antibodies indicated that all but three IgM belonged to the IgG1 class and contained kappa light chains. Immunoblotting experiments using peptides derived from H1(0) or H5 treated by various proteolytic agents (trypsin, N-bromosuccinimide, cyanogen bromide, acetic acid), revealed that nine of the mAb reacted with the globular part of H1(0). More advanced characterization of the antigenic determinants allowed us to determine distinct regions within this globular part which are involved in the antigenic recognition. The peptopes could be subdivided into two groups. Three mAb bound to residues 24-27 and were specific for H1(0). Six mAb bound to residues 27-30 and were specific for H1(0) except one of them which strongly cross-reacted with H5 and GH5. Two mAb reacted with the entire histone H1(0) but failed to react with any of the peptides, suggesting that the corresponding epitope is a conformational antigenic determinant. In order to confirm the localization of the two distinct regions which are involved in the antigenic recognition, a synthetic decapeptide corresponding to the beginning of human H1(0) globular part (from residue 19 to residue 28) was synthesized. Inhibition experiments of the reaction between H1(0) and the various IgG1 mAb by increasing amounts of peptide-bovine serum albumin conjugates were then performed.

This work reports on the observations of γ-rays from the shell-type supernova remnant RXJ0852.0-4622 carried out with the High Energy Stereoscopic System in February 2004. H.E.S.S., a system of four imaging Cherenkov telescopes, is dedicated to the observation of γ-rays of energies between 100 GeV and several tens of TeV. Emission of -rays from RXJ0852.0-4622 was detected with a significance of 12σ within a live time of 3.2 h. The morphology of the emission region is clearly extended and correlated with the morphology of the X-ray emission. A differential energy spectrum of the photon flux between 0.5 and 10TeV was reconstructed. It is found to follow a power law dN/dE ∝E -Γ with a spectral index of Γ=2.1 ±0.1 stat ±0.2 syst . The integral photon flux above 1 TeV from the entire remnant is (1.9 ±0.3 stat ±0.4 syst ) x 10 -11 cm -2 s -1 which is at the level of the Crab flux at these energies, establishing RXJ0852.0-4622 as one of the brightest γ-ray sources in the sky. RXJ0852.0-4622 is the second supernova remnant of which an extended γ-ray morphology could be proved. The observed energy flux in γ-rays between 0.5 and 10 TeV is calculated to be (9 ±1 stat ±2 syst ) x 10 -11 erg cm -2 s -1 . Based on the energy flux in X-rays the expected energy flux due to inverse Compton scattering of relativistic electrons on the cosmic microwave background is estimated. It is found to be several orders of magnitude lower than the observed flux, suggesting that another radiation component significantly contributes to the γ-ray emission of RXJ0852.0-4622. In strong interactions of relativistic protons with the ambient interstellar material neutral pions are produced. The decay of these pions produce γ-rays. The distance to RXJ0852.0-4622 and the density of the ambient interstellar material are open parameters in the interpretation. It is shown for a wide range of these parameters that the transfer of several percent of the kinetic energy of the supernova remnant

An investigation of CP violation was performed using a total of 24 candidates for B^0 -> J/psi K^0_S decay, with a purity of about 60%. These events were selected from 4.4 million hadronic Z^0 decays recorded by the OPAL detector at LEP. An analysis procedure, involving techniques to reconstruct the proper decay times and tag the produced b-flavours, B^0 or B^0(bar), has been developed to allow a first direct study of the time dependent CP asymmetry that, in the Standard Model, is sin(2beta). The result is sin(2beta) = 3.2_{-2.0}^{+1.8} +/- 0.5, where the first error is statistical and the second systematic. This result is used to determine probabilities for different values of sin(2beta) in the physical region from -1 to +1.
Measurement of the CP violation in the Bs0 → J/ψφ decay channel with the LHCb detector

International Nuclear Information System (INIS)

Maurice, E.

2012-01-01

The measurement of the CP violating φ s phase in the B s 0 → J/φφ decays is one of the main goals of the LHCb experiment. The predicted value of this observable by the Standard Model has a small theoretical uncertainty. New Physics could significantly modify this measurement, with the presence of new particles in the B s 0 - Anti-B s 0 oscillation's box diagrams. During this thesis, we have contributed to many aspects of B s 0 → J/ψφ analysis. We proposed a multivariate selection, based on a boosted decision trees algorithm. This new selection adds 19% signal to the B s 0 → J/ψφ signal but it requires a time correction. We have studied the main sources of angular distortions B s 0 → J/ψφ decays. We have found that the detector's geometry has the most important impact on the angular distributions. We have participated to another key element of the φ s analysis: the flavour tagging. In order to determine the initial B Flavour, a tagging algorithm has been developed. It exploits charged tracks originating from the b-hadron opposite to the signal B-meson. We have taken part into its optimization and calibration, by studying the B d 0 → J/ψK * channel. With 1 fb -1 corresponding to the whole 2011 data, after the optimization and calibration of this algorithm, the tagging power is measured in the B s 0 → J/ψφ channel: (2.29 ± 0.07 ± 0.26) %. The φ s measurement in the B s 0 → J/ψφ channel is: φ s = (-0.001 ± 0.101 ± 0.027) rad. The combined analysis of B s 0 → J/ψφ and B s 0 → J/ψπ + π - decays gives the most precise measurement of φ s = (-0.002 ± 0.083 ± 0.027) rad. This Measurement is compatible with the Standard Model, but there is still room for New Physics. (author)
Near-infrared colorimetry of J6 Himalia and S9 Phoebe - A summary of 0.3- to 2.2-micron reflectances

Science.gov (United States)

Degewij, J.; Cruikshank, D. P.; Hartmann, W. K.

1980-01-01

VJHK measurements of J6 Himalia and S9 Phoebe, using the new NASA IRTF telescope, show that these objects have carbonaceous chondritic type colors in the 0.5- to 2.2-micron region. For Phoebe, this is in contrast to the JHK colors published by Cruikshank (1980), which indicated that the satellite's surface was unlike the material found on asteroids and on the dark side of Iapetus. J6 is known to have a low albedo from thermal infrared studies (Cruikshank, 1977), and the new VJHK observations of S9 imply that it also has a low albedo. The H and K reflectances of S9 are slightly lower than those of J6, suggesting some slight difference in surface composition or a contamination by foreign material. The conjectured low albedo of S9 can be tested with measurements in the thermal infrared.

We present fully sampled 38'' resolution maps of the CO and 13 CO J = 2-1 lines in the molecular clouds toward the H II region complex W3. The maps cover a 2. 0 0 x 1. 0 67 section of the galactic plane and span -70 to -20 km s -1 (LSR) in velocity with a resolution of ∼1.3 km s -1 . The velocity range of the images includes all the gas in the Perseus spiral arm. We also present maps of CO J = 3-2 emission for a 0. 0 5 x 0. 0 33 area containing the H II regions W3 Main and W3(OH). The J = 3-2 maps have velocity resolution of 0.87 km s -1 and 24'' angular resolution. Color figures display the peak line brightness temperature, the velocity-integrated intensity, and velocity channel maps for all three lines, and also the (CO/ 13 CO) J = 2-1 line intensity ratios as a function of velocity. The line intensity image cubes are made available in standard FITS format as electronically readable files. We compare our molecular line maps with the 1.1 mm continuum image from the BOLOCAM Galactic Plane Survey (BGPS). From our 13 CO image cube, we derive kinematic information for the 65 BGPS sources in the mapped field, in the form of Gaussian component fits.

Constraints on H(0) from globular clusters

International Nuclear Information System (INIS)

Vandenberg, D.A.

1988-01-01

On the basis of canonical stellar evolutionary computations, the maximum age of the globular clusters is suggested to be near either 14 Gyr or 18 Gyr, depending on how (O/Fe) varies with (Fe/H) in the cluster stars. The lower estimate requires that H(0) = 65 km/s/Mpc or less, for all Omega(0) = O or greater, if the standard Big-Bang cosmological theory is correct - while the higher age value similarly constrains the Hubble constant to be smaller than 46 km/s/Mpc. Some reduction in the upper limit to cluster ages and a consequent increase in H(0) may be expected if helium diffusion is important in Population II stars; nevertheless, values of H(0) greater than 75 km/s/Mpc still appear to be precluded unless the cosmological constant is nonzero. 51 refs

Highlights: → The stability of the equilibrium adsorption states is determined after the geometry optimization. → The origin of the stable chemisorbed state is analyzed by the electronic structure and charge redistribution calculation. → The dissociation energetics of H2 are investigated in details by the PES and CINEB calculation. - Abstract: The adsorption and dissociation of H 2 molecules on the Zr(0 0 0 1) surface are systematically investigated by using density functional theory within the generalized gradient approximation and a supercell approach. After geometry optimization, the most stable equilibrium adsorption state is found to be along the top-y entrance. By calculating the adiabatic potential energy surface, the chemisorbed molecular adsorption states are also identified to be along the parallel channel at the top site. The electronic properties of the stable chemisorbed molecular state are analyzed, which show that the interaction between the molecule and substrate is of covalent characteristic with a sizeable charge redistribution. On the other hand, the hcp site is turned out to be the most stable equilibrium adsorption site for hydrogen atom on Zr(0 0 0 1) surface after the dissociation of H 2 . The dissociation energetics of H 2 are studied by calculating the potential energy surface and the minimum energy path of the transition state is determined by using the climb image nudged elastic band method, wherein the fcc-y channel is found to be most stable and favorable for dissociative adsorption of H 2 among the five possible dissociative paths. Remarkably, we find that the adiabatic dissociation process of H 2 is an activated type but with a small energy barrier, which is well consistent with the macroscopic phenomenon that the zirconium metal is easily hydrogenated.
Reactive scattering for H{sup -} + H{sub 2} and H{sup +} + H{sub 2} and its isotopologues. Classical versus quantum investigation

In the present doctoral thesis, the reactive scattering for H{sup -} + H{sub 2} and H{sup +} + H{sub 2} and its isotopologues were investigated using different methods to solve the equations describing classical and quantum mechanics. The studies aimed at providing insights into elementary reactions, and may even go beyond these to more complex chemical reactions. The main results in this dissertation can be summarized as follows: In Chapter 2 the equations solving problems in quasi-classical mechanics were described, which led to the definition of energy dependent reaction probabilities P{sub r}(E{sub rel}, v, j) = (N{sub r})/(N{sub tot}) and reaction cross sections σ{sub R} = πP{sub r}(E{sub rel}, v, j)b{sup 2}{sub max}. The formalism for time-dependent methods for the investigation of scattering processes was presented in Chapter 3. In this section we discussed how to use the time-dependent quantum wavepacket method to study the A-BC system. The dependence of the reaction probabilities P{sup J}{sub reac}(E) on the total angular momenta J was calculated to obtain information about the integral reactive cross section σ{sup tot}(E) = (π)/(k{sup 2}{sub vj})Σ{sub J}(2J + 1)P{sup J}{sub reac}(E). The potential energy surfaces (PESs) for H{sup +}{sub 3} and H{sup -}{sub 3} were described in Chapter 4. For the H{sup +}{sub 3} system, a cut through the potential energy surface (PES) in the asymptotic region was presented. For the H{sup -}{sub 3} system three available ab initio potential energy surfaces have been used in the applications: a) Staerck and Meyer (SM-PES), b) Panda and Sathyamurthy (PS-PES), and c) Ayouz et al. (AY-PES). The differences in the PESs were investigated. In the beginning of Chapter 5 the H{sup +} + H{sub 2}(v=0-5, j=0) collision was investigated nonadiabatically. By comparison of the reaction probabilities using adiabatic and non-adiabatic representations of the potential energy surfaces, it was found that, at low collision energies, the
The Phase Transitions between H 0.27V 0.27W 0.73O 3· {1}/{3} H 2O and V 0.27W 0.73O 2.865: An X-Ray, Thermal Analysis, and HREM Study

A mixed vanadium-tungsten oxide hydrate (H 0.27V 0.27W 0.73O 3· {1}/{3}H 2O) has been synthesized by a soft chemistry method, and the phase transitions from the hydrate (precursor) to the final product V 0.27W 0.73O 2.865have been studied by thermal analysis, X-ray powder diffraction, and high-resolution electron microscopy (HREM) techniques. Supermetastable, metastable, and stable oxides have been observed. H 0.27V 0.27W 0.73O 3· {1}/{3}H 2O possesses a structure related to WO 3· {1}/{3}H 2O. Dehydration of the precursor leads to a supermetastable phase, H 0.27V 0.27W 0.73O 3, with a structure similar to that of the hydrate. At 350°C this phase transforms to the metastable H 0.27V 0.27W 0.73O 3, with a structure isotypic with WO 3(hex). The phase transition between the hydrate and H 0.27V 0.27W 0.73O 3is both pseudomorphous and topotactic. Removal of hydrogen and oxygen from the metastable oxide induces a second phase transition at 500°C to a more stable phase, V 0.27W 0.73O 2.865, with an oxygen-deficient WO 3-type structure. The monoclinic symmetry of the latter oxide increases at higher temperature, first to orthorhombic and then to tetragonal. This transition is not pseudomorphous but of a topotactic nature. The obtained results suggest that the hydrogen content stabilizes the WO 3(hex)-related structure of the metastable phase. A hypothetical model based on HREM observations is proposed for the structural transformation H 0.27V 0.27W 0.73O 3→V 0.27W 0.73O 2.865.

The observation of exotic structures in the $J/\\psi p$ channel, refered to as pentaquark-charmonium states, in the decay $\\Lambda^0_b \\rightarrow J/\\psi K^- p$, are presented. An amplitude analysis is performed on the three-body final state that reproduces the two-body mass and angular distributions. To obtain a satisfactory fit of the structures seen in the $J/\\psi p$ mass spectrum, it is necessary to include two Breit-Wigner amplitudes that each describe a resonant state. The significance of each of these resonances is more than 9 standard deviations. One has a mass of 4380 $\\pm$ 8 $\\pm$ 29 MeV and a width of 205 $\\pm$ 18 $\\pm$ 86 MeV, while the second is narrower, with a mass of 4449.8 $\\pm$ 1.7 $\\pm$ 2.5 MeV and a width of 39 $\\pm$ 5 $\\pm$ 19. The preferred $J^P$ assignments are of opposite parity, with one state having spin 3/2 and the other 5/2.

Exposure of the cornea to UV radiation from sunlight evokes intraocular inflammation, photokeratitis. Photokeratitis is caused by UVB radiation. It is accompanied by changes of corneal hydration and light absorption. The aim of this study was to examine the effect of two UVB doses on corneal optics in rabbits and to compare these UVB doses with the equivalent exposure of UVB radiation reaching the human cornea from sunlight. Rabbit corneas were irradiated with a daily UVB dose of 0.25 J/cm(2) or 0.5 J/cm(2) for 4 days. One day after finishing the irradiations the rabbits were sacrificed and corneal light absorption measured using our spectrophotometrical method. Corneal hydration was examined using an ultrasonic Pachymeter every experimental day before the irradiation procedure and the last day before sacrificing the animals. Changes in corneal optics appeared after the repeated exposure of the cornea to a UVB dose of 0.25 J/ cm(2) and massively increased after the repeated exposure of the cornea to a UVB dose of 0.5 J/cm(2). The first significant changes in corneal hydration appeared after a single exposure of the cornea to a UVB dose of 0.25 J/cm(2). Changes in corneal hydration appeared after the exposure of the rabbit cornea to a single UVB dose equivalent to 2.6 hours of solar UVB radiation reaching the human cornea, as measured by UVB sensors embedded in the eyes of mannequin heads facing the sun on a beach at noon in July. Repeated exposure of the rabbit cornea to the same UVB dose evoked profound changes in corneal optics. Although comparison of experimental and outdoor conditions are only approximate, the results in rabbits point to the danger for the human eye from UVB radiation when short stays in sunlight are repeated for several consecutive days without UV protection.

The first measurement of C P asymmetries in the decay B{sub s}{sup 0}→J / ψ ( K)-bar {sup ∗}(892){sup 0} and an updated measurement of its branching fraction and polarisation fractions are presented. The results are obtained using data corresponding to an integrated luminosity of 3.0 fb{sup −1} of proton-proton collisions recorded with the LHCb detector at centre-of-mass energies of 7 and 8 TeV. Together with constraints from B{sup 0}→J / ψ ρ{sup 0}, the results are used to constrain additional contributions due to penguin diagrams in the C P-violating phase ϕ{sub s}, measured through B{sub s}{sup 0} decays to charmonium.

The influence of partial substitution of La by Dy on the magnetocaloric response of (La 1-x Dy x ) 0.67 Ca 0.33 Mn 0.9 V 0.1 O 3 , where x=0.03, 0.15 and 0.25 is studied. Rietveld refinement of X-ray diffraction pattern using GSAS method shows that the compounds adopt the orthorhombic structure with Pnma space group. The systematic change in lattice parameters and magnetic phase transition indicates the substitution effect of Dy. From the magnetization isotherms at different temperatures, magnetic entropy change close to their respective transition temperatures (T C ) has been evaluated. The maximum value of entropy change near T C is found to be about 4.8 J/kg K at 187.5 K for LCMVDy 0.03 , 2.45 J/kg K at 107.5 K for LCMVDy 0.15 and 2.15 J/kg K at 92.5 K for LCMVDy 0.25 at 4 T. Dy addition produces a reduction in T C and in magnitude of the magnetic entropy change. Even though the entropy change decreases with increasing Dy substitution the refrigerant temperature range, ΔT, is found to be 10 K for LCMVDy 0.03 , 31 K for LCMVDy 0.15 and 35 K for LCMVDy 0.25 compounds [90%] at 4 T. The field dependence of the magnetic entropy change is also analyzed showing the power law dependence, ΔS M ∞H n where n=0.75(2) for LCMVDy 0.03 , n=0.80(4) for LCMVDy 0.15 and n=0.92(8) for LCMVDy 0.25 compounds at their respective transition temperatures. The relative cooling power and its field dependance are also analyzed. - Highlights: → Studied magnetocaloric response of Dy substituted solid state synthesized LCMVO. → Studied the field dependence of the magnetic entropy change (ΔS M ∞H n ). → Studied the field dependence of Relative cooling power (RCP∞H 1+1/δ ). → Considerably large magnetocaloric effect and moderate relative cooling power.

A re-analysis of the INTEGRAL Galactic Bulge monitoring observation on February 13 (ATel #3172) shows that the flaring behaviour reported from SAX J1747.0-2853 is in fact due to a superburst. The event started on February 13, 2011 at 13:01:40 UTC with a 2 minutes spike, but the JEM-X (3-30 keV) s...

Observations of exotic structures in the $J/\\psi p$ channel, that we refer to as pentaquark-charmonium states, in $\\Lambda_b^0\\to J/\\psi K^- p$ decays are presented. The data sample corresponds to an integrated luminosity of 3/fb acquired with the LHCb detector from 7 and 8 TeV pp collisions. An amplitude analysis is performed on the three-body final-state that reproduces the two-body mass and angular distributions. To obtain a satisfactory fit of the structures seen in the $J/\\psi p$ mass spectrum, it is necessary to include two Breit-Wigner amplitudes that each describe a resonant state. The significance of each of these resonances is more than 9 standard deviations. One has a mass of $4380\\pm 8\\pm 29$ MeV and a width of $205\\pm 18\\pm 86$ MeV, while the second is narrower, with a mass of $4449.8\\pm 1.7\\pm 2.5$ MeV and a width of $39\\pm 5\\pm 19$ MeV. The preferred $J^P$ assignments are of opposite parity, with one state having spin 3/2 and the other 5/2.

Observations of exotic structures in the J/ψp channel, which we refer to as charmonium-pentaquark states, in Λ_{b}^{0}→J/ψK^{-}p decays are presented. The data sample corresponds to an integrated luminosity of 3 fb^{-1} acquired with the LHCb detector from 7 and 8 TeV pp collisions. An amplitude analysis of the three-body final state reproduces the two-body mass and angular distributions. To obtain a satisfactory fit of the structures seen in the J/ψp mass spectrum, it is necessary to include two Breit-Wigner amplitudes that each describe a resonant state. The significance of each of these resonances is more than 9 standard deviations. One has a mass of 4380±8±29 MeV and a width of 205±18±86 MeV, while the second is narrower, with a mass of 4449.8±1.7±2.5 MeV and a width of 39±5±19 MeV. The preferred J^{P} assignments are of opposite parity, with one state having spin 3/2 and the other 5/2.

The B{sup 0}–B{sup ¯0} oscillation frequency Δm{sub d} is measured by the LHCb experiment using a dataset corresponding to an integrated luminosity of 1.0 fb{sup −1} of proton–proton collisions at √(s)=7 TeV, and is found to be Δm{sub d}=0.5156±0.0051(stat.)±0.0033(syst.) ps{sup −1}. The measurement is based on results from analyses of the decays B{sup 0}→D{sup −}π{sup +} (D{sup −}→K{sup +}π{sup −}π{sup −}) and B{sup 0}→J/ψK{sup ⁎0} (J/ψ→μ{sup +}μ{sup −},K{sup ⁎0}→K{sup +}π{sup −}) and their charge conjugated modes.
Local Two-Photon Couplings and the J=0 Fixed Pole in Real and Virtual Compton Scattering

The local coupling of two photons to the fundamental quark currents of a hadron gives an energy-independent contribution to the Compton amplitude proportional to the charge squared of the struck quark, a contribution which has no analog in hadron scattering reactions. We show that this local contribution has a real phase and is universal, giving the same contribution for real or virtual Compton scattering for any photon virtuality and skewness at fixed momentum transfer squared t. The t-dependence of this J = 0 fixed Regge pole is parameterized by a yet unmeasured even charge-conjugation form factor of the target nucleon. The t = 0 limit gives an important constraint on the dependence of the nucleon mass on the quark mass through the Weisberger relation. We discuss how this 1=x form factor can be extracted from high energy deeply virtual Compton scattering and examine predictions given by models of the H generalized parton distribution.

Homotopy Theory contains all the published mathematical work of J. H. C. Whitehead, written between 1947 and 1955. This volume considers the study of simple homotopy types, particularly the realization of problem for homotopy types. It describes Whitehead's version of homotopy theory in terms of CW-complexes.This book is composed of 21 chapters and begins with an overview of a theorem to Borsuk and the homotopy type of ANR. The subsequent chapters deal with four-dimensional polyhedral, the homotopy type of a special kind of polyhedron, and the combinatorial homotopy I and II. These topics are

Using 4.479×10^{8} ψ(3686) events collected with the BESIII detector, we search for the decays ψ(3686)→e^{+}e^{-}χ_{cJ} and χ_{cJ}→e^{+}e^{-}J/ψ, where J=0, 1, 2. The decays ψ(3686)→e^{+}e^{-}χ_{cJ} and χ_{cJ}→e^{+}e^{-}J/ψ are observed for the first time. The measured branching fractions are B(ψ(3686)→e^{+}e^{-}χ_{cJ})=(11.7±2.5±1.0)×10^{-4}, (8.6±0.3±0.6)×10^{-4}, (6.9±0.5±0.6)×10^{-4} for J=0, 1, 2, and B(χ_{cJ}→e^{+}e^{-}J/ψ)=(1.51±0.30±0.13)×10^{-4}, (3.73±0.09±0.25)×10^{-3}, (2.48±0.08±0.16)×10^{-3} for J=0, 1, 2, respectively. The ratios of the branching fractions B(ψ(3686)→e^{+}e^{-}χ_{cJ})/B(ψ(3686)→γχ_{cJ}) and B(χ_{cJ}→e^{+}e^{-}J/ψ)/B(χ_{cJ}→γJ/ψ) are also reported. Also, the α values of helicity angular distributions of the e^{+}e^{-} pair are determined for ψ(3686)→e^{+}e^{-}χ_{c1,2} and χ_{c1,2}→e^{+}e^{-}J/ψ.

Objective: To compare the course of radiation pulmonary injury in C57BL/6J and C3H/HeN mice. Methods: C57BL/6J and C3H/HeN mice irradiated with 20 Gy 60 Co gamma rays were used as animal models. Sirius red staining and hydroxyproline measurement were used to detect the distribution of type I and III collagens and the content of pulmonary hydroxyproline. Immunohistochemistry was used to observe the changes of the expressions of fibronectin (FN) and laminin (LN) and alpha-smooth muscle actin (α-SMA) in the lung. Results: The changes in the lungs in C57BL/6J mice were as follows: the pathological changes undergone interstitial pneumonia, proliferation and fibrosis; significant increase of collagen deposition; FN increased rapidly to a significantly higher level at 1 and 3 months after irradiation than that in the control (P<0.01), and then decreased gradually to a normal level at 6 month after irradiation; LN elevated gradually after irradiation; the expressions of α-SMA were more intense than that in C3H/HeN mice. The changes in the lungs in C3H/HeN mice were as follows: the pathological changes mainly developed institial pneumonitis; no significant changes of FN expression was observed after irradiation compared to that in the control; LN increased significantly at 1 and 3 months after irradiation, and then decreased gradually. Conclusions: The models of radiation pulmonary fibrosis-sensitive and-resistant were established by irradiation with gamma rays, C57BL/6J mice developed late radiation pulmonary fibrosis, and were characterized by the significant accumulation of collagen. C3H/HeN mice did not develop radiation pulmonary fibrosis. (authors)
Recent results from Heliotron J

Recent 70-GHz, 0.4-MW ECH experiments in Heliotron J have revealed the existence of the spontaneous confinement transition, like that of H-mode, at rather low threshold line-averaged densities of 1.2-1.6 x 10 19 m -3 . The transition was discovered in two edge iota windows: one is 0.54<ι(a)/2π<0.56 at separatrix discharge plasmas and the other is 0.62<ι(a)/2π<0.63 at partial wall-limiter plasmas. The energy confinement time for the separatrix discharge plasmas was found to be enhanced beyond the normal ISS95 scaling in the transient H-mode phase, being 50% better than that in the ''before transition'' phase. The bootstrap current properties, ECCD experiments and the initial 0.7-MW NBI H-mode characteristics are also discussed. (orig.)

The shell-type supernova remnant HESS J1731 - 347 emits TeV gamma-rays, and is a key object for the study of the cosmic ray acceleration potential of supernova remnants. We use 0.5-1 arcmin Mopra CO/CS(1-0) data in conjunction with H I data to calculate column densities towards the HESS J1731 - 347 region. We trace gas within at least four Galactic arms, typically tracing total (atomic+molecular) line-of-sight H column densities of 2-3× 1022 cm-2. Assuming standard X-factor values and that most of the H I/CO emission seen towards HESS J1731 - 347 is on the near-side of the Galaxy, X-ray absorption column densities are consistent with H I+CO-derived column densities foreground to, but not beyond, the Scutum-Crux Galactic arm, suggesting a kinematic distance of ˜3.2 kpc for HESS J1731 - 347. At this kinematic distance, we also find dense, infrared-dark gas traced by CS(1-0) emission coincident with the north of HESS J1731 - 347, the nearby H II region G353.43-0.37 and the nearby unidentified gamma-ray source HESS J1729 - 345. This dense gas lends weight to the idea that HESS J1729 - 345 and HESS J1731 - 347 are connected, perhaps via escaping cosmic-rays.

Angular correlations in $B^+\\to X(3872) K^+$ decays, with $X(3872)\\to \\rho^0 J/\\psi$, $\\rho^0\\to\\pi^+\\pi^-$ and $J/\\psi \\to\\mu^+\\mu^-$, are used to measure orbital angular momentum contributions and to determine the $J^{PC}$ value of the $X(3872)$ meson. The data correspond to an integrated luminosity of 3.0 fb$^{-1}$ of proton-proton collisions collected with the LHCb detector. This determination, for the first time performed without assuming a value for the orbital angular momentum, confirms the quantum numbers to be $J^{PC}=1^{++}$. The $X(3872)$ is found to decay predominantly through S wave and an upper limit of $4\\%$ at $95\\%$ C.L. is set on the fraction of D wave.
The dual role of Candida glabrata Drug:H+ Antiporter CgAqr1 (ORF CAGL0J09944g in antifungal drug and acetic acid resistance

Full Text Available Opportunistic Candida species often have to cope with inhibitory concentrations of acetic acid, in the acidic environment of the vaginal mucosa. Given that the ability of these yeast species to tolerate stress induced by weak acids and antifungal drugs appears to be a key factor in their persistence and virulence, it is crucial to understand the underlying mechanisms.In this study, the Drug:H+ Antiporter CgAqr1 (ORF CAGL0J09944g, from Candida glabrata, was identified as a determinant of resistance to acetic acid, and also to the antifungal agents flucytosine and, less significantly, clotrimazole. These antifungals were found to act synergistically with acetic acid against this pathogen. The action of CgAqr1 in this phenomenon was analyzed. Using a GFP fusion, CgAqr1 was found to localize to the plasma membrane and to membrane vesicles when expressed in C. glabrata or, heterologously, in Saccharomyces cerevisiae. Given its ability to complement the susceptibility phenotype of its S. cerevisiae homolog, ScAqr1, CgAqr1 was proposed to play a similar role in mediating the extrusion of chemical compounds. Significantly, the expression of this gene was found to reduce the intracellular accumulation of 3H-flucytosine and, to a moderate extent, of 3H-clotrimazole, consistent with a direct role in antifungal drug efflux. Interestingly, no effect of CgAQR1 deletion could be found on the intracellular accumulation of 14C-acetic acid, suggesting that its role in acetic acid resistance may be indirect, presumably through the transport of a still unidentified physiological substrate. Although neither of the tested chemicals induces changes in CgAQR1 expression, pre-exposure to flucytosine or clotrimazole was found to make C. glabrata cells more sensitive to acetic acid stress. Results from this study show that CgAqr1 is an antifungal drug resistance determinant and raise the hypothesis that it may play a role in C. glabrata persistent colonization and
Evidence for Stable v = 0, j = 1 → 0 SiO Maser Emission from VY Canis Majoris

Observations of the SiO v = 0, J = 1 → 0 spectra from VY CMa from 2003 through 2006 indicate an unusually long-lived, highly linearly polarized maser emission at a V lsr of approximately 18.5 km s-1. A time series cross-correlation analysis has been developed for calculating the characteristic lifetime of linearly polarized spectra. Applying the cross-correlation to these spectra indicates a characteristic lifetime of 5600 ± 400 days. These emission characteristics may be generated in a region of relatively stable outflow geometry and magnetic field rather than in the more ephemeral circumstellar environment.

Graphene controlled H- and J-stacking of perylene dyes into highly stable supramolecular nanostructures for enhanced photocurrent generation

DEFF Research Database (Denmark)

2014-01-01

We report a new method for controlling H- and J-stacking in supramolecular self-assembly. Graphene nanosheets act as structure inducers to direct the self-assembly of a versatile organic dye, perylene into two distinct types of functional nanostructures, i.e. one-dimensional nanotubes via J......-stacking and two-dimensional branched nanobuds through H-stacking. Graphene integrated supramolecular nanocomposites are highly stable and show significant enhancement of photocurrent generation in these two configurations of photosensing devices, i.e. solid-state optoelectronic constructs and liquid...
Interference between Coulombic and CT-mediated couplings in molecular aggregates: H- to J-aggregate transformation in perylene-based π-stacks

The spectroscopic differences between J and H-aggregates are traditionally attributed to the spatial dependence of the Coulombic coupling, as originally proposed by Kasha. However, in tightly packed molecular aggregates wave functions on neighboring molecules overlap, leading to an additional charge transfer (CT) mediated exciton coupling with a vastly different spatial dependence. The latter is governed by the nodal patterns of the molecular LUMOs and HOMOs from which the electron (t{sub e}) and hole (t{sub h}) transfer integrals derive. The sign of the CT-mediated coupling depends on the sign of the product t{sub e}t{sub h} and is therefore highly sensitive to small (sub-Angstrom) transverse displacements or slips. Given that Coulombic and CT-mediated couplings exist simultaneously in tightly packed molecular systems, the interference between the two must be considered when defining J and H-aggregates. Generally, such π-stacked aggregates do not abide by the traditional classification scheme of Kasha: for example, even when the Coulomb coupling is strong the presence of a similarly strong but destructively interfering CT-mediated coupling results in “null-aggregates” which spectroscopically resemble uncoupled molecules. Based on a Frenkel/CT Holstein Hamiltonian that takes into account both sources of electronic coupling as well as intramolecular vibrations, vibronic spectral signatures are developed for integrated Frenkel/CT systems in both the perturbative and resonance regimes. In the perturbative regime, the sign of the lowest exciton band curvature, which rigorously defines J and H-aggregation, is directly tracked by the ratio of the first two vibronic peak intensities. Even in the resonance regime, the vibronic ratio remains a useful tool to evaluate the J or H nature of the system. The theory developed is applied to the reversible H to J-aggregate transformations recently observed in several perylene bisimide systems.

FeSe 0.5 Te 0.5 thin films were grown by pulsed laser deposition on CaF 2 , LaAlO 3 and MgO substrates and structurally and electro-magnetically characterized in order to study the influence of the substrate on their transport properties. The in-plane lattice mismatch between FeSe 0.5 Te 0.5 bulk and the substrate shows no influence on the lattice parameters of the films, whereas the type of substrate affects the crystalline quality of the films and, therefore, the superconducting properties. The film on MgO showed an extra peak in the angular dependence of critical current density J c (θ) at θ = 180° (H||c), which arises from c-axis defects as confirmed by transmission electron microscopy. In contrast, no J c (θ) peaks for H||c were observed in films on CaF 2 and LaAlO 3 . J c (θ) can be scaled successfully for both films without c-axis correlated defects by the anisotropic Ginzburg–Landau approach with appropriate anisotropy ratio γ J . The scaling parameter γ J is decreasing with decreasing temperature, which is different from what we observed in FeSe 0.5 Te 0.5 films on Fe-buffered MgO substrates. (paper)
Structural, magnetic and transport studies of Mn0.8Cr0.2CoGe alloy

Different physical and functional properties of Mn0.8Cr0.2CoGe alloy has been investigated through structural, magnetic and electrical transport measurements. Substitution of Cr for Mn results significant decrease in both structural and magnetic transition temperature and brings them well below the room temperature. A reasonable amount of conventional magnetocaloric effect (ΔS˜ - 2.22 J/kg-K for magnetic field (H) changing from 0 to 50 kOe) with large relative cooling power (251.7 J/kg for H changing from 0 to 50 kOe) has also been observed around the region of transition. On thermal cycling through the structural transition, noticeable training effect is found to be associated with the resistivity of the alloy.

Rotational excitation of the hydrogen cyanide (HCN) molecule by collisions with para-H{sub 2}( j = 0, 2) and ortho-H{sub 2}( j = 1) is investigated at low temperatures using a quantum time independent approach. Both molecules are treated as rigid rotors. The scattering calculations are based on a highly correlated ab initio 4-dimensional (4D) potential energy surface recently published. Rotationally inelastic cross sections among the 13 first rotational levels of HCN were obtained using a pure quantum close coupling approach for total energies up to 1200 cm{sup −1}. The corresponding thermal rate coefficients were computed for temperatures ranging from 5 to 100 K. The HCN rate coefficients are strongly dependent on the rotational level of the H{sub 2} molecule. In particular, the rate coefficients for collisions with para-H{sub 2}( j = 0) are significantly lower than those for collisions with ortho-H{sub 2}( j = 1) and para-H{sub 2}( j = 2). Propensity rules in favor of even Δj transitions were found for HCN in collisions with para-H{sub 2}( j = 0) whereas propensity rules in favor of odd Δj transitions were found for HCN in collisions with H{sub 2}( j ⩾ 1). The new rate coefficients were compared with previously published HCN-para-H{sub 2}( j = 0) rate coefficients. Significant differences were found due the inclusion of the H{sub 2} rotational structure in the scattering calculations. These new rate coefficients will be crucial to improve the estimation of the HCN abundance in the interstellar medium.
Crossed molecular beams study of the reaction D+H2→DH+H at collision energies of 0.53 and 1.01 eV

This paper reports the first product differential cross section (DCS) measurements for the D+H 2 →DH+H reaction as a function of laboratory (LAB) scattering angle with sufficient resolution to resolve product DH vibrational states. Using a D-atom beam produced by the photodissociation of DI at 248 nm, product velocity and angular distributions were measured at 12 LAB angles at a nominal collision energy of 0.53 eV and at 22 LAB angles at a nominal collision energy of 1.01 eV with a crossed molecular beams apparatus. After correction of the raw product time-of-flight (TOF) spectra for modulated background, a comparison with recent exact quantum mechanical scattering calculations was made using a Monte Carlo simulation of the experimental conditions. The simulation showed that although the theoretical predictions agree qualitatively with the measurements, some significant discrepancies exist. Using the Monte Carlo simulation, a best-fit set of DH(v,j) DCS's which showed good agreement with the measurements was found. At the detailed level of the state-to-state DCS, significant differences were observed between theory and experiment for rotationally excited DH(v, j) products. The discrepancies observed suggest that some regions of the current ab initio H 3 potential energy surfaces, particularly the bending potential at high energies, may need further examination

We report measurements of the carbon monoxide ground state rotational transition ({sup 12}C{sup 16}O J = 1-0) with the Zpectrometer ultrawideband spectrometer on the 100 m diameter Green Bank Telescope. The sample comprises 11 galaxies with redshifts between z = 2.1 and 3.5 from a total sample of 24 targets identified by Herschel-ATLAS photometric colors from the SPIRE instrument. Nine of the CO measurements are new redshift determinations, substantially adding to the number of detections of galaxies with rest-frame peak submillimeter emission near 100 {mu}m. The CO detections confirm the existence of massive gas reservoirs within these luminous dusty star-forming galaxies (DSFGs). The CO redshift distribution of the 350 {mu}m selected galaxies is strikingly similar to the optical redshifts of 850 {mu}m-selected submillimeter galaxies in 2.1 {<=} z {<=} 3.5. Spectroscopic redshifts break a temperature-redshift degeneracy; optically thin dust models fit to the far-infrared photometry indicate characteristic dust temperatures near 34 K for most of the galaxies we detect in CO. Detections of two warmer galaxies, and statistically significant nondetections, hint at warmer or molecule-poor DSFGs with redshifts that are difficult to determine from Herschel-SPIRE photometric colors alone. Many of the galaxies identified by H-ATLAS photometry are expected to be amplified by foreground gravitational lenses. Analysis of CO linewidths and luminosities provides a method for finding approximate gravitational lens magnifications {mu} from spectroscopic data alone, yielding {mu} {approx} 3-20. Corrected for magnification, most galaxy luminosities are consistent with an ultraluminous infrared galaxy classification, but three are candidate hyper-LIRGs with luminosities greater than 10{sup 13} L{sub Sun }.
Fitting law for the density shift of Q(J) transitinos of H2 in H2-X (X: H2, He, N2) mixtures

A variety of fitting laws have been developed for the purpose of modelling broadening effects in collisional processes, but only a few have been proposed for modelling collision-induced lineshifts in molecules. We analysed accurate stimulated Raman data obtained in several H 2 -X mixtures (X: H 2 , He and N 2 ). For the first time, we show that an empirical law provides a very good representation of collisional lineshift coefficients in the range 300-1200 K and for J quantum number up to 9.

On employing H216O, H217O, H218O, and D216O lines as frequency standards in the 15-170 cm-1 window

The protocol MARVEL, standing for measured active rotational-vibrational energy levels, is used to study high-accuracy measurements of rotational lines of four isotopologues of water, H 2 16 O, H 2 17 O, H 2 18 O, and D 2 16 O, obtained by spectroscopy in the far-infrared (FIR) region of 15-170 cm -1 by Matsushima et al. [Matsushima F, Odashima H, Iwasaki T, Tsunekawa S, Takagi K. Frequency measurement of pure rotational transitions of H 2 O from 0.5 to 5 THz. J Mol Struct 1995; 352/353, 371-8; Matsushima F, Nagase H, Nakauchi T, Odashima H, Takagi K. Frequency measurement of pure rotational transitions of H 2 17 O and H 2 18 O from 0.5 to 5 THz.

J Mol Spectrosc 2006;235: 190-5]. MARVEL validates the high accuracy of most of the measured line positions. It results in a considerable number of energy levels with an average internal uncertainty of only 40 kHz (2σ). It also supports serious inaccuracy problems when Watson-type A-reduced Hamiltonians are used for predicting the highly accurate rotational measurements for water. Finally, MARVEL suggests a large number of para-water levels, for example 41 for H 2 16 O, which are candidates for becoming frequency standards in the FIR region of 15-170 cm -1 (the 0.5-5 THz window) when an accuracy of about 0.1 MHz is deemed to be sufficient

The evolution of the rest-frame J- and H-band luminosity function of galaxies to z=3.5

2011-01-01

We present the rest-frame J- and H-band luminosity function (LF) of field galaxies, based on a deep multi-wavelength composite sample from the MUSYC, FIRES and FIREWORKS survey public catalogues, covering a total area of 450 arcmin^2. The availability of flux measurements in the Spitzer IRAC 3.6, 4.5, 5.8, and 8 um channels allows us to compute absolute magnitudes in the rest-frame J and H bands up to z=3.5 minimizing the dependence on the stellar evolution models. We compute the LF in the fo...

Supernova remnants exhibit shock fronts (shells) that can accelerate charged particles up to very high energies. In the past decade, measurements of a handful of shell-type supernova remnants in very high-energy gamma rays have provided unique insights into the acceleration process. Among those objects, RX J1713.7-3946 (also known as G347.3-0.5) has the largest surface brightness, allowing us in the past to perform the most comprehensive study of morphology and spatially resolved spectra of any such very high-energy gamma-ray source. Here we present extensive new H.E.S.S. measurements of RX J1713.7-3946, almost doubling the observation time compared to our previous publication. Combined with new improved analysis tools, the previous sensitivity is more than doubled. The H.E.S.S. angular resolution of 0.048° (0.036° above 2 TeV) is unprecedented in gamma-ray astronomy and probes physical scales of 0.8 (0.6) parsec at the remnant's location. The new H.E.S.S. image of RX J1713.7-3946 allows us to reveal clear morphological differences between X-rays and gamma rays. In particular, for the outer edge of the brightest shell region, we find the first ever indication for particles in the process of leaving the acceleration shock region. By studying the broadband energy spectrum, we furthermore extract properties of the parent particle populations, providing new input to the discussion of the leptonic or hadronic nature of the gamma-ray emission mechanism. All images (FITS files) are available at the CDS via anonymous ftp to http://cdsarc.u-strasbg.fr (http://130.79.128.5) or via http://cdsarc.u-strasbg.fr/viz-bin/qcat?J/A+A/612/A6
Electron paramagnetic resonance of Na, [(FeEDTA)2oJ-12H20] crystal electrons

International Nuclear Information System (INIS)

Esquivel, Darci Motta de Souza

1974-01-01

Crystals of Na [(Fe EDTA) 2 o] ·12H 2 0 were investigated by means of electron paramagnetic resonance spectroscopy. The spectra were obtained at various temperatures and crystals orientations. These spectra are very complex with many absorption bands. As the crystal orientation with respect to the magnetic field was changed the variations of the intensity and number of bands were recorded. The antiferromagnetic coupling between the iron atoms in the bridge Fe - 0 - Fe gives rise to states with total spin quantum number S= 0, 1, 2, 3, 4 and 5. Analyses of the EPR spectra as a function of temperature provided a means for the identification of the EPR absorption bands attributed to the states with S = 2. It was also possible to calculate the exchange parameter value J = 300 K. From the study of bands angular dependence in relation to the crystal orientation in the magnetic field it was found that the magnetic crystal axes X, Y, Z and the crystals axes a, b, c are related as (a, b, c) = (Y, Z, X) ! with a precision of 5 deg. Also the crystalline distortion parameters were calculated D = 0.21 ± 0.02 cm 1 ; E = 0.015 ± 0.005 cm 1 . (author)

The B^0_s differential production cross section is measured as functions of the transverse momentum and rapidity in pp collisions at sqrt(s) = 7 TeV, using the J/Psi phi decay, and compared with predictions based on perturbative QCD calculations at next-to-leading order. The data sample, collected by the CMS experiment at the LHC, corresponds to an integrated luminosity of 40 inverse picobarns. The B^0_s is reconstructed from the decays J/Psi to an oppositely charged muon pair and phi to K+ K-. The integrated B^0_s cross section times B^0_s to J/Psi phi branching fraction in the range 8 < pt(B) < 50 GeV/c and |y(b)| < 2.4 is measured to be 6.9 +/- 0.6 +/- 0.6 nb, where the first uncertainty is statistical and the second is systematic.

We report a measurement of the Lambda b0 lifetime in the exclusive decay Lambda b0-->J/psi Lambda 0 in pp collisions at square root s=1.96 TeV using an integrated luminosity of 1.0 fb-1 of data collected by the CDF II detector at the Fermilab Tevatron. Using fully reconstructed decays, we measure tau(Lambda b0)=1.593(-0.078)(+0.083)(stat)+/-0.033(syst) ps. This is the single most precise measurement of tau(Lambda b0) and is 3.2sigma higher than the current world average.
Observation of B(0)(s)-->Psi(2S)Phi and measurement of the ratio of branching fractions Beta(B(0)(s)-->Psi(2S)Phi)/Beta(B(0)(s)-->J/PsiPhi).

The interference between $B_s^0$ decays to $J/\\psi \\phi$ either directly or via $B_s^0-\\bar{B}_s^0$ oscillation gives rise to a $CP$ violating phase $\\phi_s$. Using a sample of about $21,200$ $B_s^0\\to J/\\psi \\phi$ events extracted from 1$fb^{-1}$ of $pp$ collisions collected during the 2011 LHC run at a center of mass energy of $\\sqrt{s}=7$ TeV, we fit for nine physics parameters, including the phase $\\phi_s$, the mean decay width difference $\\Delta\\Gamma_s$ and the decay width $\\Gamma_s$.

Highlights: ► BDE(Se–H)s of C 6 H 5 SeH and its para and meta-substituted derivatives are calculated. ► A relationship between the BDE(Se–H)s and Mulliken atomic spin densities of YC 6 H 4 Se radical is found. ► Good correlations are also observed between the BDE(Se–H)s and the Hammett’s parameters. ► The proton affinity of C 6 H 5 SeH is evaluated to be in the range of 814–818 kJ/mol. ► Ionization energies (IE) of the substituted benzeneselenols are also evaluated. - Abstract: Bond dissociation enthalpies (BDE) of benzeneselenol (ArSe-H) and its para and meta-substituted derivatives are calculated using the (RO)B3LYP/6-311++G(2df,2p)//(U)B3LYP/6-311G(d,p) procedure. The computed BDE(Se–H) = 308 ± 8 kJ/mol for the parent PhSe-H is significantly smaller than the experimental value of 326.4 ± 16.7 kJ/mol [Kenttamaa and coworkers, J. Phys. Chem. 100 (1996) 6608] but larger than a previous value of 280.3 kJ/mol [Newcomb et al., J. Am. Chem. Soc. 113 (1991) 949]. The substituent effects on BDE’s are analyzed in terms of a relationship between BDE(Se–H) and Mulliken atomic spin densities at the Se radical centers of ArSe (π radicals). Good correlations between Hammett’s substituent constants with BDE(Se–H) are established. Proton affinity and ionization energy amount to PA(C 6 H 5 SeH) = 814 ± 4 kJ/mol and IE(C 6 H 5 SeH) = 8.0 ± 0.1 eV. IEs of the substituted benzeneselenols are also determined. Calculated results thus suggest that 4-amino-benzeneselenol derivatives emerge as efficient antioxidants

Recent evidence indicates that genetic hypertension in BPH/2J mice is sympathetically mediated, but these mice also have lower body weight (BW) and elevated locomotor activity compared with BPN/3J normotensive mice, suggestive of metabolic abnormalities. The aim of the present study was to determine whether hypertension in BPH/2J mice is associated with metabolic differences. Whole-body metabolic and cardiovascular parameters were measured over 24 h by indirect calorimetry and radiotelemetry respectively, in conscious young (10-13 weeks) and older (22-23 weeks) BPH/2J, normotensive BPN/3J and C57Bl6 mice. Blood pressure (BP) was greater in BPH/2J compared with both normotensive strains at both ages (PBPH/2J compared with BPN/3J mice (PBPH/2J and normotensive mice when adjusted for activity (P>0.1) suggesting differences in this relationship are not responsible for hypertension. EchoMRI revealed that percentage body composition was comparable in BPN/3J and BPH/2J mice (P>0.1) and both strains gained weight similarly with age (P=0.3). Taken together, the present findings indicate that hypertension in BPH/2J mice does not appear to be related to altered energy metabolism.
DsJ(2860) as the First Radial Excitation of Ds0*(2317)

2006-11-01

A coupled-channel model previously employed to describe the narrow Ds0*(2317) and broad D0*(2400) charmed scalar mesons is generalized so as to include all ground-state pseudoscalar-pseudoscalar and vector-vector two-meson channels. All parameters are chosen fixed at published values, except for the overall coupling constant, which is fine-tuned to reproduce the Ds0*(2317) mass. Thus, the radial excitations Ds0*(2850) and D0*(2740) are predicted, both with a width of about 50 MeV. The former state appears to correspond to the new DsJ(2860) resonance decaying to DK announced by BABAR in the course of this work. Also, the D0*(2400) resonance is roughly reproduced, though perhaps with a somewhat too low central resonance peak.

This note presents an update of the B$^0$ $\\rightarrow$ J/$\\psi$($\\mu\\mu$)K$^0_S$($\\pi^+\\pi^-$) analysis in order to obtain the LHCb sensitivity to sin(2$/beta$). We present two selection criteria, one considering only lifetime unbiased cuts and another which includes lifetime biased cuts to reduce further the background contamination. For an integrated luminosity of 2 fb$^-1$ and after L0 trigger, we estimate a yield of 193k events for the B$^0$ $\\rightarrow$ J/$\\psi$($\\mu\\mu$)K$^0_S$ channel with the lifetime unbiased selection criteria, with a total background to signal ration 3.43. For the lifetime biased selection, the signal yield is 208k events and the background to signal ratio is to 0.63. The statistical sensitivity on sin(2$/beta$) is found to be 0.023 and 0.020 for the unbiased and biased selections, respectively.

The first analysis of heavy flavour production measured by the LHCb experiment in fixed-target mode is presented. The $J/\\psi$ and $D^0$ production processes are studied in 6.5 TeV proton-beam-induced reactions on an argon gaseous target. About 500 $J/\\psi \\to \\mu^+ \\mu^-$ and 6500 $D^0 \\to K^- \\pi^+$ decays are reconstructed. Their yields are studied as a function of transverse momentum, rapidity, Bjorken-$x$ and Feynman-$x$. No strong dependence of the $J/\\psi / D^0$ cross-section ratio on rapidity is observed.
Tagged time-dependent angular analysis of $B^0_s \\to J/\\psi\\phi$ decays with the 2010 LHCb data

The interference between $B^0_s$ decays to $J\\psi\\phi$ either directly or via $B^0_s-\\bar{B}^0_s$ oscillation gives rise to a CP violating phase $\\phi_s^{J/\\psi\\phi}$. In the Standard Model, this phase is approximately -2$\\beta_s$, where $\\beta_s$ = arg (-$V_{ts}V_{tb}^*/V_{cs}V_{cb}^*$). We have performed a measurement of $\\phi^{J\\psi\\phi}_s$ using a sample that contains 836 $\\pm$ 60 $B^0_s\\to J/\\psi\\phi$ events extracted from 36 pb$^{-1}$ of $pp$ collisions collected during the 2010 LHC run at $\\sqrt{s}$ = 7 TeV. The result is presented as a two-dimensional region in the $\\phi_s$-$\\Delta\\Gamma_s$ plane. The probability of a fluctuation from the Standard Model expectation to the observed result for $\\phi_s$ and $\\Delta\\Gamma_s$ is 22% (``1.2$\\sigma$''). We derive a one-dimensional interval at 68% CL of $\\phi_s \\in$ [-2.7, -0.5] rad.

A search for time-integrated $CP$ violation in $D^0 \\rightarrow h^-h^+$ ($h=K$, $\\pi$) decays is presented using 0.62~fb$^{-1}$ of data collected by LHCb in 2011. The flavor of the charm meson is determined by the charge of the slow pion in the $D^{*+} \\rightarrow D^0 \\pi^+$ and $D^{*-} \\rightarrow \\overline{D}^0 \\pi^-$ decay chains. The difference in $CP$ asymmetry between $D^0 \\rightarrow K^- K^+$ and $D^0 \\rightarrow \\pi^- \\pi^+$, $\\Delta A_{CP} \\equiv A_{CP}(K^-K^+) \\, - \\, A_{CP}(\\pi^-\\pi^+)$, is measured to be $\\left[ -0.82 \\pm 0.21 (\\mathrm{stat.}) \\pm 0.11 (\\mathrm{syst.}) \\right]\\%$. This differs from the hypothesis of $CP$ conservation by $3.5$ standard deviations.
Estudio dinámico de un potencial perturbador dependiente de dos parámetros

Miloni, O.; Brunini, A.

El objeto del presente trabajo consiste en el estudio dinámico de un sistema dinámico caracterizado por la función hamiltoniana correspondiente a un satélite planetario perturbado por la acción del Sol y del achatamiento del planeta madre. Cuando dicha Hamiltoniana se promedia respecto de los términos de corto período, esta queda con dos grados de libertad, y su estudio puede ser realizado con las herramientas clásicas de la dinámica no-lineal. Se tratará de determinar regiones regulares y caóticas de movimiento. En el caso de estas últimas, es de particular interés la determinación de su orígen.
Observation of $J/\\psi$ p resonances consistent with pentaquark states in$\\wedge_ b^0$ → $J/\\psi K^−p$ decays

AUTHOR|(INSPIRE)INSPIRE-00400750

The observation of structures consistent with charmonium-pentaquark states decaying to $J/\\psi p$ in $\\wedge_b^0$ → $J/\\psi K^−p$ decays is presented. The data sample analyzed corresponds to an integrated luminosity of $3 fb^−1$ acquired with the LHCb detector from 7 and 8 TeV $pp$ collisions. An amplitude analysis was performed which utilized all six kinematic degrees of freedom in the decay. It was shown that adequate descriptions of the data are unattainable with only $K^−p$ resonances in the amplitude model. For satisfactory fits of the data, it was found to be necessary to include two $J/\\psi p$ resonances, with each having significances of over 9 standard deviations. One has a mass of $4449.8 \\pm1.7\\pm2.2 MeV$ and a width of $39\\pm5\\pm16 MeV$, while the second is broader, with a mass of $4380 \\pm8\\pm29 MeV$ and a width of $205\\pm18\\pm87 MeV$. The $J^P$ assignments could not be uniquely determined, though there is a preference for one to have spin 3/2 and the other spin 5/2 with an opposite parit...

LHCb: Measurement of the polarization amplitudes of the decay $B^0 \\rightarrow J/\\psi K^\\ast$

Using the data sample recorded with the LHCb detector in 2010 we perform a combined angular and lifetime analysis of the decay $B^0 \\rightarrow J/\\psi K^\\ast$. The data corresponds to an integrated luminosity of about 36 pb$^{-1}$ and was taken at the LHC at an centre-of-mass energy of $\\sqrt{s}$= 7 TeV. A total of 3909 $J/\\psi K^*$ candidates are found and are used to extract the polarisation amplitudes and the corresponding strong phases for the decays $B_d \\rightarrow J/\\psi K^\\ast$.

Magnetic refrigerants incorporating Gd 3+ ions and light organic ligands offer a good balance between isolation of the magnetic centers and their density. We synthesized the framework material Gd 2 (C 2 O 4 ) 3 (H 2 O) 6 ⋅0.6H 2 O by a hydrothermal route and characterized its structure. The honeycomb lattice of Gd 3+ ions interlinked by oxalate ligands in the (a,c) plane ensures their decoupling in terms of magnetic exchange interactions. This is corroborated by magnetic measurements indicating negligible interactions between the Gd 3+ ions in this material. The magnetocaloric effect was evaluated from isothermal magnetization measurements. The maximum entropy change −ΔS M max reaches 75.9 mJ cm −3 K −1 (around 2 K) for a moderate field change (2 T)

Density-functional theory calculations had been used to investigate the adsorption and dissociation of H 2 S on Mo(1 0 0) surface. Adsorption mechanisms of H 2 S, HS, S and H on the Mo(1 0 0) surface were analyzed. H 2 S was found to be adsorbed at bridge, hollow and top sites with adsorption energies of −1.25, −1.03 and −0.92 eV, respectively. HS was strongly chemically absorbed at hollow, bridge and top sites with adsorption energies of −4.51, −4.08 and −3.45 eV, respectively, and sulfur and hydrogen preferred to be absorbed at hollow and bridge sites, respectively. In addition, potential energy profiles of H 2 S dissociation on Mo(1 0 0) had been constructed by a climbing image nudged elastic band method. Four possible dissociation pathways of the first H 2 S dehydrogenation were examined with reaction barriers of 0.28, 0.37, 0.075, and 0.21 eV, respectively, while the energy barrier to break the S-H bond of HS with or without hydrogen co-adsorption was almost the same low. This work showed that the decomposition of H 2 S on the molybdenum surface was kinetically and thermodynamically facile. Local densities of electronic states were further used to characterize the interaction between H 2 S and substrate.

A search is performed for the charmless three-body decays of the $\\Lambda_b^0$ and $\\Xi_b^0$ baryons to the final states $\\Lambda h^+h^{\\prime -}$, where $h^{(\\prime)} = \\pi$ or $K$. The analysis is based on a data sample, corresponding to an integrated luminosity of $3 \\rm fb^{-1}$ of $pp$ collisions, collected by the LHCb experiment. The $\\Lambda_b^0 \\to \\Lambda K^+\\pi^-$ and $\\Lambda_b^0 \\to \\Lambda K^+K^-$ decays are observed for the first time and their branching fractions and $CP$ asymmetry parameters are measured. Evidence is seen for the $\\Lambda_b^0 \\to \\Lambda \\pi^+\\pi^-$ decay and limits are set on the branching fractions of $\\Xi_b^0$ baryon decays to the $\\Lambda h^+h^{\\prime -}$ final states.
Studying Higgs pair production in the process γγ→H0H0 in the two-Higgs-doublet model

International Nuclear Information System (INIS)

La-Zhen, S.; Yao-Yang, L.

1996-01-01

In the two-Higgs-doublet model the complete nonstandard Higgs boson helicity amplitudes for the Higgs boson pair production process γγ→H 0 H 0 is calculated and explicit formulas for nonstandard Higgs boson contributions to the helicity amplitudes are given. It is shown that the cross section is in the range of 0.03 endash 30 pb at √s=1 TeV, for Higgs boson masses of 350 H 0 <490 GeV in monochromatic γγ collisions. The angular distribution for Higgs pair production is strongly peaked in the forward and backward directions. In particular the angular dependence for Higgs pair production is due to the nonstandard Higgs boson getting larger where the box diagrams constitute the dominant part of the differential cross section. For studying heavy Higgs pair production the use of circularly polarized photon beams with equal helicities is advantageous. copyright 1996 The American Physical Society

The H.E.S.S. Collaboration has discovered a new very high energy (VHE, E > 0.1 TeV) γ-ray source, HESS J1741-302, located in the Galactic plane. Despite several attempts to constrain its nature, no plausible counterpart has been found so far at X-ray and MeV/GeV γ-ray energies, and the source remains unidentified. An analysis of 145-h of observations of HESS J1741-302 at VHEs has revealed a steady and relatively weak TeV source ( 1% of the Crab Nebula flux), with a spectral index of Γ = 2.3 ± 0.2stat ± 0.2sys, extending to energies up to 10 TeV without any clear signature of a cut-off. In a hadronic scenario, such a spectrum implies an object with particle acceleration up to energies of several hundred TeV. Contrary to most H.E.S.S. unidentified sources, the angular size of HESS J1741-302 is compatible with the H.E.S.S. point spread function at VHEs, with an extension constrained to be below 0.068° at a 99% confidence level. The γ-ray emission detected by H.E.S.S. can be explained both within a hadronic scenario, due to collisions of protons with energies of hundreds of TeV with dense molecular clouds, and in a leptonic scenario, as a relic pulsar wind nebula, possibly powered by the middle-aged (20 kyr) pulsar PSR B1737-30. A binary scenario, related to the compact radio source 1LC 358.266+0.038 found to be spatially coincident with the best fit position of HESS J1741-302, is also envisaged.

H ii regions are particularly interesting because they can generate dense layers of gas and dust, elongated columns or pillars of gas pointing toward the ionizing sources, and cometary globules of dense gas where triggered star formation can occur. Understanding the interplay between the ionizing radiation and the dense surrounding gas is very important to explain the origin of these peculiar structures, and hence to characterize triggered star formation. G46.5-0.2 (G46), a poorly studied galactic H ii region located at about 4 kpc, is an excellent target for performing this kind of study. Using public molecular data extracted from the Galactic Ring Survey ( 13 CO J = 1–0) and from the James Clerk Maxwell Telescope data archive ( 12 CO, 13 CO, C 18 O J = 3–2, HCO + , and HCN J = 4–3), and infrared data from the GLIMPSE and MIPSGAL surveys, we perform a complete study of G46, its molecular environment, and the young stellar objects (YSOs) placed around it. We found that G46, probably excited by an O7V star, is located close to the edge of the GRSMC G046.34-00.21 molecular cloud. It presents a horse-shoe morphology opening in the direction of the cloud. We observed a filamentary structure in the molecular gas likely related to G46 and not considerable molecular emission toward its open border. We found that about 10′ to the southwest of G46 there are some pillar-like features, shining at 8 μm and pointing toward the H ii region open border. We propose that the pillar-like features were carved and sculpted by the ionizing flux from G46. We found several YSOs likely embedded in the molecular cloud grouped in two main concentrations: one, closer to the G46 open border consisting of Class II type sources, and another mostly composed of Class I type YSOs located just ahead of the pillar-like features, strongly suggesting an age gradient in the YSO distribution

Avian leukosis virus subgroup J (ALV-J), first isolated in the late 1980s, has caused economic losses to the poultry industry in many countries. As all chicken lines studied to date are susceptible to ALV infection, there is enormous interest in developing resistant chicken lines. The ALV-J receptor, chicken Na + /H + exchange 1 (chNHE1) and the critical amino acid sequences involved in viral attachment and entry have already been characterized. However, there are no reported attempts to induce resistance to the virus by targeted genome modification of the receptor sequences. In an attempt to induce resistance to ALV-J infection, we used clustered regularly interspaced short palindromic repeats (CRISPR)-associated (CRISPR/Cas9)-based genome editing approaches to modify critical residues of the chNHE1 receptor in chicken cells. The susceptibility of the modified cell lines to ALV-J infection was examined using enhanced green fluorescent protein (EGFP)-expressing marker viruses. We showed that modifying the chNHE1 receptor by artificially generating a premature stop codon induced absolute resistance to viral infection, with mutations of the tryptophan residue at position 38 (Trp38) being very critical. Single-stranded oligodeoxynucleotide (ssODN)-mediated targeted recombination of the Trp38 region revealed that deletions involving the Trp38 residue were most effective in conferring resistance to ALV-J. Moreover, protein structure analysis of the chNHE1 receptor sequence suggested that its intrinsically disordered region undergoes local conformational changes through genetic alteration. Collectively, these results demonstrate that targeted mutations on chNHE1 alter the susceptibility to ALV-J and the technique is expected to contribute to develop disease-resistant chicken lines.

Aim. We present a multiwavelength study of two southern Galactic H II regions G346.056-0.021 and G346.077-0.056 which are located at a distance of 10.9 kpc. The distribution of ionized gas, cold and warm dust, and the stellar population associated with the two H II regions are studied in detail using measurements at near-infrared, mid-infrared, far-infrared, submillimeter and radio wavelengths. Methods: The radio continuum maps at 1280 and 610 MHz were obtained using the Giant Metrewave Radio Telescope to probe the ionized gas. The dust temperature, column density, and dust emissivity maps were generated using modified blackbody fits in the far-infrared wavelength range 160-500 μm. Various near- and mid-infrared color and magnitude criteria were adopted to identify candidate ionizing star(s) and the population of young stellar objects in the associated field. Results: The radio maps reveal the presence of diffuse ionized emission displaying distinct cometary morphologies. The 1280 MHz flux densities translate to zero age main sequence spectral types in the range O7.5V-O7V and O8.5V-O8V for the ionizing stars of G346.056-0.021 and G346.077-0.056, respectively. A few promising candidate ionizing star(s) are identified using near-infrared photometric data. The column density map shows the presence of a large, dense dust clump enveloping G346.077-0.056. The dust temperature map shows peaks towards the two H II regions. The submillimeter image shows the presence of two additional clumps, one being associated with G346.056-0.021. The masses of the clumps are estimated to range between 1400 and 15250 M⊙. Based on simple analytic calculations and the correlation seen between the ionized gas distribution and the local density structure, the observed cometary morphology in the radio maps is better explained invoking the champagne-flow model.

The present study has developed an efficient and eco-friendly protocol for the synthesis of aryl-14-H-dibenzo[a,j] xanthenes through a one-pot condensation reaction of 2-naphthol and arylaldehydes in aqueous media using the nanocatalytic MCM-41-SO3H under ultrasonic illumination. Using SEM and XRD analyses, MCM-41-SO3H nanoparticles were characterized. Therefore, for high magnification, taking the SEM image, the mesoporous surface of MCM-41-SO3H nanoparticles coated with gold for 2 minutes was characterized. Moreover, at a scan rate of 0.02° (2θ)/sec, XRD analysis from 1.5° (2θ) to 10.0° (2θ) was performed. For our considered sample, some well-ordered XRD patterns with one main peak as well as three minor peaks equal to those of MCM-41 materials were observed. The suggested route demonstrates very promising properties like higher yields, decrease in the time of reaction (5-10 min), mild and straightforward conditions, low level of toxicity, and inclusion of a cost-efficient and ecofriendly catalyst having considerable reusability.

Pair Identity and Smooth Variation Rules Applicable for the Spectroscopic Parameters of H2O Transitions Involving High-J States

Science.gov (United States)

Ma, Q.; Tipping, R. H.; Lavrentieva, N. N.

2010-01-01

Two basic rules (i.e. the pair identity and the smooth variation) applicable for H2O transitions involving high-J states have been discovered. The origins of these rules are the properties of the energy levels and wavefunctions of H2O states with the quantum number J above certain boundaries. As a result, for lines involving high-J states in individually defined groups, all their spectroscopic parameters (i.e. the transition wavenumber, intensity, pressure-broadened half-width, pressure-induced shift, and temperature exponent) must follow these rules. One can use these rules to screen spectroscopic data provided by databases and to identify possible errors. In addition, by using extrapolation methods within the individual groups, one is able to predict the spectroscopic parameters for lines in this group involving very high-J states. The latter are required in developing high-temperature molecular spectroscopic databases such as HITEMP.
Di-J/ψ Studies, Level 3 Tracking and the D0 Run IIb Upgrade

The D0 detector underwent an upgrade to its silicon vertex detector and triggering systems during the transition from Run IIa to Run IIb to maximize its ability to fully exploit Run II at the Fermilab Tevatron. This thesis describes improvements made to the tracking and vertexing algorithms used by the high level trigger in both Run IIa and Run IIb, as well as a search for resonant di-J/ψ states using both Run IIa and Run IIb data. Improvements made to the tracking and vertexing algorithms during Run IIa included the optimization of the existing tracking software to reduce overall processing time and the certification and testing of a new software release. Upgrades made to the high level trigger for Run IIb included the development of a new tracking algorithm and the inclusion of the new Layer 0 silicon detector into the existing software. The integration of Layer 0 into the high level trigger has led to an improvement in the overall impact parameter resolution for tracks of ∼50%. The development of a new parameterization method for finding the error associated to the impact parameter of tracks returned by the high level tracking algorithm, in association with the inclusion of Layer 0, has led to improvements in vertex resolution of ∼4.5 (micro)m. A previous search in the di-J/ψ channel revealed a unpredicted resonance at ∼13.7 GeV/c 2 . A confirmation analysis is presented using 2.8 fb -1 of data and two different approaches to cuts. No significant excess is seen in the di-J/ψ mass spectrum.

The perspectives of decoding the nature of the a0(980) and f0(980) mesons and of defining the relative phase between the three-gluon and one-photon amplitudes in the J/ψ decays

It is argued that the search of the J/ψ → f 0 (980)ω and J/ψ → a 0 (980)ρ decays and the more precise definition of B(J/ψ → f 0 (980)φ) are the urgent purposes in the J/ψ spectroscopy. It is shown that the study of the ω - ρ 0 interference pattern in the J/ψ → (ρ 0 + ω)η → π + π - η decay provides evidence for the large (nearly 90deg) relative phase between the isovector one-photon and three-gluon decay amplitudes.

Exposure of graphite to multispecies hydrogenic impact, as is the case in tokamaks, could lead to synergistic mechanisms resulting in an enhancement of methane formation, and consequently in increased carbon erosion. We present results obtained in controlled experiments in our laboratories in Toronto and Juelich for the synergistic methane production due to combined sub-eV H 0 atoms and energetic H + ion impact on pyrolytic graphite. Flux densities were 10 14 -2x10 16 H 0 /cm 2 s for the sub-eV H 0 atoms and 6x10 12 -5x10 15 H + /cm 2 for H + ions of 300 eV to 2.5 keV energy. Synergistic factors (defined as the ratio of methane formation rate due to combined H 0 and H + fluxes to the sum of the formation rates due to separate species impact) ranged from about 1.5-15 for the experimental parameters used. In addition, a spectrum of formed hydrocarbons in the synergistic reaction of H + and H 0 on graphite is presented

Inelastic scattering computations are presented for collisions of vibrationally and rotationally excited CO with H{sub 2} in full dimension. The computations utilize a newly developed six-dimensional potential energy surface (PES) and the previously reported four-dimensional V12 PES [P. Jankowski et al., J. Chem. Phys. 138, 084307 (2013)] and incorporate full angular-momentum coupling. At low collision energies, pure rotational excitation cross sections of CO by para-, ortho-, and normal-H{sub 2} are calculated and convolved to compare with recent measurements. Good agreement with the measured data is shown except for j{sub 1} = 0 → 1 excitation of CO for very low-energy para-H{sub 2} collisions. Rovibrational quenching results are presented for initially excited CO(v{sub 1}j{sub 1}) levels with v{sub 1} = 1, j{sub 1} = 1–5 and v{sub 1} = 2, j{sub 1} = 0 for collisions with para-H{sub 2} (v{sub 2} = 0, j{sub 2} = 0) and ortho-H{sub 2} (v{sub 2} = 0, j{sub 2} = 1) over the kinetic energy range 0.1–1000 cm{sup −1}. The total quenching cross sections are found to have similar magnitudes, but increase (decrease) with j{sub 1} for collision energies above ∼300 cm{sup −1} (below ∼10 cm{sup −1}). Only minor differences are found between para- and ortho-H{sub 2} colliders for rovibrational and pure rotational transitions, except at very low collision energies. Likewise, pure rotational deexcitation of CO yields similar cross sections for the v{sub 1} = 0 and v{sub 1} = 1 vibrational levels, while rovibrational quenching from v{sub 1} = 2, j{sub 1} = 0 is a factor of ∼5 larger than that from v{sub 1} = 1, j{sub 1} = 0. Details on the PES, computed at the CCSD(T)/aug-cc-pV5Z level, and fitted with an invariant polynomial method, are also presented.

Quantum mechanical study of the proton exchange in the ortho-para H2 conversion reaction at low temperature.

2011-11-14

Ortho-para H(2) conversion reactions mediated by the exchange of a H(+) proton have been investigated at very low energy for the first time by means of a time independent quantum mechanical (TIQM) approach. State-to-state probabilities and cross sections for H(+) + H(2) (v = 0, j = 0,1) processes have been calculated for a collision energy, E(c), ranging between 10(-6) eV and 0.1 eV. Differential cross sections (DCSs) for H(+) + H(2) (v = 0, j = 1) → H(+) + H(2) (v' = 0, j' = 0) for very low energies only start to develop a proper global minimum around the sideways scattering direction (θ≈ 90°) at E(c) = 10(-3) eV. Rate coefficients, a crucial information required for astrophysical models, are provided between 10 K and 100 K. The relaxation ortho-para process j = 1 → j' = 0 is found to be more efficient than the j = 0 → j' = 1 conversion at low temperatures, in line with the extremely small ratio between the ortho and para species of molecular hydrogen predicted at the temperature of interstellar cold molecular clouds. The results obtained by means of a statistical quantum mechanical (SQM) model, which has previously proved to provide an adequate description of the dynamics of the title reactions at a higher collision energy regime, have been compared with the TIQM results. A reasonable good agreement has been found with the only exception of the DCSs for the H(+) + H(2) (v = 0, j = 1) → H(+) + H(2) (v' = 0, j' = 0) process at very low energy. SQM cross sections are also slightly below the quantum results. Estimates for the rate coefficients, in good accord with the TIQM values, are a clear improvement with respect to pioneering statistical studies on the reaction.

Algebraic and Classical Topology contains all the published mathematical work of J. H. C. Whitehead, written between 1952 and 1960.This volume is composed of 21 chapters, which represent two groups of papers. The first group, written between 1952 and 1957, is principally concerned with fiber spaces and the Spanier-Whitehead S-theory. In the second group, written between 1957 and 1960, Whitehead returns to classical topology after a long interval, and participates in the renewed assault on the problems which fascinated him most. This book will prove useful to mathematicians.
Weighing 'El Gordo' with a precision scale: Hubble space telescope weak-lensing analysis of the merging galaxy cluster ACT-CL J0102–4915 at z = 0.87

We present a Hubble Space Telescope weak-lensing study of the merging galaxy cluster 'El Gordo' (ACT-CL J0102–4915) at z = 0.87 discovered by the Atacama Cosmology Telescope (ACT) collaboration as the strongest Sunyaev-Zel'dovich decrement in its ∼1000 deg 2 survey. Our weak-lensing analysis confirms that ACT-CL J0102–4915 is indeed an extreme system consisting of two massive (≳ 10 15 M ☉ each) subclusters with a projected separation of ∼0.7 h 70 −1 Mpc. This binary mass structure revealed by our lensing study is consistent with the cluster galaxy distribution and the dynamical study carried out with 89 spectroscopic members. We estimate the mass of ACT-CL J0102–4915 by simultaneously fitting two axisymmetric Navarro-Frenk-White (NFW) profiles allowing their centers to vary. We use only a single parameter for the NFW mass profile by enforcing the mass-concentration relation from numerical simulations. Our Markov-Chain-Monte-Carlo analysis shows that the masses of the northwestern (NW) and the southeastern (SE) components are M 200c =(1.38±0.22)×10 15 h 70 −1 M ⊙ and (0.78±0.20)×10 15 h 70 −1 M ⊙ , respectively, where the quoted errors include only 1σ statistical uncertainties determined by the finite number of source galaxies. These mass estimates are subject to additional uncertainties (20%-30%) due to the possible presence of triaxiality, correlated/uncorrelated large scale structure, and departure of the cluster profile from the NFW model. The lensing-based velocity dispersions are 1133 −61 +58 km s −1 and 1064 −66 +62 km s −1 for the NW and SE components, respectively, which are consistent with their spectroscopic measurements (1290 ± 134 km s –1 and 1089 ± 200 km s –1 , respectively). The centroids of both components are tightly constrained (∼4'') and close to the optical luminosity centers. The X-ray and mass peaks are spatially offset by ∼8'' (∼62 h 70 −1 kpc), which is

In this paper, we present the theoretical studies of a refractive index map to implement a Gauss to a J0-Bessel-Gauss convertor. We theoretically demonstrate the viability of a device that could be fabricated on a Si/Si1-yOy/Si1-x-yGexCy platform or by photo-refractive media. The proposed device is 200 ?m in length and 25 ?m in width, and its refractive index varies in controllable steps across the light propagation and transversal directions. The computed conversion efficiency and loss are 90%, and -0.457 dB, respectively. The theoretical results, obtained from the beam conversion efficiency, self-regeneration, and propagation through an opaque obstruction, demonstrate that a two-dimensional (2D) graded index map of the refractive index can be used to transform a Gauss beam into a J0-Bessel-Gauss beam. To the best of our knowledge, this is the first demonstration of such beam transformation by means of a 2D index-mapping that is fully integrable in silicon photonics based planar lightwave circuits (PLCs). The concept device is significant for the eventual development of a new array of technologies, such as micro optical tweezers, optical traps, beam reshaping and nonlinear beam diode lasers. © 2012 Optical Society of America.

We report on gamma-ray observations of the supernova remnant (SNR) RX J0852.0-4622 with the Large Area Telescope (LAT) on board the Fermi Gamma-ray Space Telescope. In the Fermi-LAT data, we find a spatially extended source at the location of the SNR. The extension is consistent with the SNR size seen in other wavelengths such as X-rays and TeV gamma rays, leading to the identification of the gamma-ray source with the SNR. The spectrum is well described as a power law with a photon index of Γ = 1.85 ± 0.06 (stat) +0.18 -0.19 (sys), which smoothly connects to the H.E.S.S. spectrum in the TeV energy band. We discuss the gamma-ray emission mechanism based on multiwavelength data. The broadband data can be fit well by a model in which the gamma rays are of hadronic origin. We also consider a scenario with inverse Compton scattering of electrons as the emission mechanism of the gamma rays. Although the leptonic model predicts a harder spectrum in the Fermi-LAT energy range, the model can fit the data considering the statistical and systematic errors.

We have studied the effect of Fe substitution on magnetic and magnetocaloric properties in La 0.7 Sr 0.3 Mn 1-x Fe x O 3 (x=0.05, 0.07, 0.10, 0.15, and 0.20) over a wide temperature range (T=10-400 K). It is shown that substitution by Fe gradually decreases the ferromagnetic Curie temperature (T C ) and saturation magnetization up to x=0.15 but a dramatic change occurs for x=0.2. The x=0.2 sample can be considered as a phase separated compound in which both short-range ordered ferromagnetic and antiferromagnetic phases coexist. The magnetic entropy change (-ΔS m ) was estimated from isothermal magnetization curves and it decreases with increase of Fe content from 4.4 J kg -1 K -1 at 343 K (x=0.05) to 1.3 J kg -1 K -1 at 105 K (x=0.2), under ΔH=5 T. The La 0.7 Sr 0.3 Mn 0.93 Fe 0.07 O 3 sample shows negligible hysteresis loss, operating temperature range over 60 K around room temperature with refrigerant capacity of 225 J kg -1 , and magnetic entropy of 4 J kg -1 K -1 which will be an interesting compound for application in room temperature refrigeration. - Research highlights: → We report magnetocaloric effect in La 0.7 Sr 0.3 Mn 1-x Fe x O 3 (x=0-0.2). → Magnetic entropy change (ΔS m ) decreases with increasing x. → A large ΔS m and refrigeration capacity are found around 300 K in x=0.07.

Precipitation-hardened 2:17-type SmCo permanent magnet has attracted much attention due to its high Curie temperature and excellent magnetic properties. Sm(Co_b_a_lFe_0_._2_4_5Cu_0_._0_7Zr_0_._0_2)_7_._8 (at%) sintered magnets with high remanence (B_r ~1.15 T) were prepared using a traditional powder metallurgy method. The intrinsic coercivity H_c_j of the magnets was increased from 429 to 994 kA m"−"1 with isothermal annealing time increasing from 10 to 40 h, which is different from the phenomenon that increasing aging time leads to a reduced coercivity mentioned in the Ref. [16]. In consideration of rarely report about the microstructure of the final magnet isothermally annealed for 40 h, we have tried to originally analyze the relationship between the microstructure and the magnetic properties. Besides, the lattice constants of sintered Sm(Co_b_a_lFe_0_._2_4_5Cu_0_._0_7Zr_0_._0_2)_7_._8 permanent magnet isothermally annealed for 40 h have been given by indexing the HRTEM results including the selected area electron diffraction (SAED) and HRTEM images.

We have searched for the b-flavored baryon decay Λ b →J/ψ Λ 0 in p bar p collisions at √s =1.8 TeV with the Collider Detector at Fermilab (CDF). In the J/ψ Λ 0 invariant-mass distribution we observe a flat distribution and a small number of events, consistent with no signal. Using the b-quark cross section measured by the CDF we put an upper limit on the b→Λ b production fraction times the branching ratio F(Λ b )B(Λ b →J/ψ Λ 0 ) of 0.50x10 -3 at 90% confidence level
Possible implications of small or large CP violation in Bd0 vs (anti B)d0→J/ΨKs decay

The author argue that a small or large CP-violating asymmetry in B d 0 vs (anti B) d 0 →J/ψK s decays, which seems to be favored by the recent BaBar or Belle data, might hint at the existence of new physics in B d 0 -(anti B) d 0 mixing. The authors present a model-independent framework to show how new physics modifies the standard-model CP-violating asymmetry. The particularly emphasize that the consistent of cp-violating asymmetry experimental result with standard model prediction must not imply the absence of new physics in B d 0 -(anti B) d 0 mixing

The large moment of inertia, large magnetic moment, and possible large permanent electric dipole moment of manganese monohydride, MnH, makes it a prime candidate for ultra-cold molecule production via Stark deceleration and magnetic trapping. Here we report the first molecular beam production of MnH and the analysis of the Stark effect in the (0,0) A^7 π -- X^ 7σ^+ band.

The J = 1 → 0 transition of HCO+ at 89 GHz has been mapped across the Helix Nebula (NGC 7293) with 70'' spatial resolution (1.68 km s-1 velocity resolution) using the Arizona Radio Observatory 12 m telescope. This work is the first large-scale mapping project of a dense gas tracer (n(H2) ~ 105 cm-3) in old planetary nebulae. Observations of over 200 positions encompassing the classical optical image were conducted with a 3σ noise level of ~20 mK. HCO+ was detected at most positions, often exhibiting multiple velocity components indicative of complex kinematic structures in dense gas. The HCO+ spectra suggest that the Helix is composed of a bipolar, barrel-like structure with red- and blue-shifted halves, symmetric with respect to the central star and oriented ~10° east from the line of sight. A second bipolar, higher velocity outflow exists as well, situated along the direction of the Helix "plumes." The column density of HCO+ across the Helix is N tot ~ 1.5 × 1010-5.0 × 1011 cm-2, with an average value N ave ~ 1 × 1011 cm-2, corresponding to an abundance, relative to H2, of f ~ 1.4 × 10-8. This value is similar to that observed in young PN, and contradicts chemical models, which predict that the abundance of HCO+ decreases with nebular age. This study indicates that polyatomic molecules readily survive the ultraviolet field of the central white dwarf, and can be useful in tracing nebular morphology in the very late stages of stellar evolution.

Non-invasive detection of 2-hydroxyglutarate (2HG) by magnetic resonance spectroscopy is attractive since it is related to tumor metabolism. Here, we compare the detection accuracy of 2HG in a controlled phantom setting via widely used localized spectroscopy sequences quantified by linear combination of metabolite signals vs. a more complex approach applying a J-difference editing technique at 9.4T. Different phantoms, comprised out of a concentration series of 2HG and overlapping brain metabolites, were measured with an optimized point-resolved-spectroscopy sequence (PRESS) and an in-house developed J-difference editing sequence. The acquired spectra were post-processed with LCModel and a simulated metabolite set (PRESS) or with a quantification formula for J-difference editing. Linear regression analysis demonstrated a high correlation of real 2HG values with those measured with the PRESS method (adjusted R-squared: 0.700, pJ-difference editing method (adjusted R-squared: 0.908, pJ-difference editing method however had a significantly higher explanatory value over the regression model with the PRESS method (pJ-difference editing 2HG was discernible down to 1mM, whereas with the PRESS method 2HG values were not discernable below 2mM and with higher systematic errors, particularly in phantoms with high concentrations of N-acetyl-asparate (NAA) and glutamate (Glu). In summary, quantification of 2HG with linear combination of metabolite signals shows high systematic errors particularly at low 2HG concentration and high concentration of confounding metabolites such as NAA and Glu. In contrast, J-difference editing offers a more accurate quantification even at low 2HG concentrations, which outweighs the downsides of longer measurement time and more complex postprocessing.

Isotopic variation of the rovibrational bound states of SO2 for the four stable sulfur isotopes 32-34,36S is investigated in comprehensive detail. In a two-part series, we compute the low-lying energy levels for all values of total angular momentum in the range J = 0-20. All rovibrational levels are computed, to an extremely high level of numerical convergence. The calculations have been carried out using the ScalIT suite of parallel codes. The present study (Paper I) examines the J = 0-10 rovibrational levels, providing unambiguous symmetry and rovibrational label assignments for each computed state. The calculated vibrational energy levels exhibit very good agreement with previously reported experimental and theoretical data. Rovibrational energy levels, calculated without any Coriolis approximations, are reported here for the first time. Among other potential ramifications, this data will facilitate understanding of the origin of mass-independent fractionation of sulfur isotopes in the Archean rock record-of great relevance for understanding the "oxygen revolution".

Five grids of stellar models have been calculated for masses ranging from 0.7 to 3.0 M/sub sun/ assuming, in turn, a metal abundance [Fe/H] = -1.0, -0.76, -0.46, -0.23, and 0.0. All of the calculations are based on a value of Y = 0.25 for the helium content and α = 1.6 for the ratio of the mixing length to the pressure scale height. The latest improvements in opacity data and nuclear reaction rates have been incorporated into the computations. Moreover, model atmospheres have been used to provide the boundary conditions for the stellar interior calculations as well as to transpose the isochrones, computed for ages from 0.3 x 10 9 to 15 x 10 9 yr, from the theoretical to the (M/sub v/, B-V)-plane. Cousins V-I and V-R colors are also predicted for each of the model sequences, which are extensively tabulated
Is HESS J1912+101 Associated with an Old Supernova Remnant?

HESS J1912+101 is a shell-like TeV source that has no clear counterpart in multiwavelength. Using CO and H i data, we reveal that V {sub LSR} ∼ +60 km s{sup −1} molecular clouds (MCs), together with shocked molecular gas and high-velocity neutral atomic shells, are concentrated toward HESS J1912+101. The prominent wing profiles up to V {sub LSR} ∼ +80 km s{sup −1} seen in {sup 12}CO ( J = 1–0 and J = 3–2) data, as well as the high-velocity expanding H i shells up to V {sub LSR} ∼ +100 km s{sup −1}, exhibit striking redshifted-broadening relative to the quiescent gas. These features provide compelling evidences for large-scale perturbation in the region. We argue that the shocked MCs and the high-velocity H i shells may originate from an old supernova remnant (SNR). The distance to the SNR is estimated to be ∼4.1 kpc based on the H i self-absorption method, which leads to a physical radius of 29.0 pc for the ∼(0.7–2.0) × 10{sup 5} years old remnant with an expansion velocity of ≳40 km s{sup −1}. The +60 km s{sup −1} MCs and the disturbed gas are indeed found to coincide with the bright TeV emission, supporting the physical association between them. Naturally, the shell-like TeV emission comes from the decay of neutral pions produced by interactions between the accelerated hadrons from the SNR and the surrounding high-density molecular gas.

We observed the X-ray counterpart of IGR J18538-0102 (Stephen et al., ATel #2441) in a pointed observation with XMM-Newton on 2004 October 8. This apparently steady source (in an 8 ks exposure) can be fitted with a power-law model of photon index 1.7+/-0.1, NH = (1.5+/-0.2)e22 cm-2, and unabsorbed 1-10 keV flux 5.6e-12 erg cm-2 s-1. Its coordinates 18h53m48.50s, -01d02'30.0" (J2000), with 90% confidence error radius of 3.2", coincide with an object in the 2MASS Point Source Catalog at 18h53m48.48s, -01d02'29.6" of magnitudes H=14.00+/-0.05 and K=12.50+/-0.05.

In a radio search with the Green Bank Telescope of three unidentified low Galactic latitude Fermi-LAT sources, we have discovered the middle-aged pulsar J2030+3641, associated with IFGL J2030.0+3641 (2FGL J2030.0+3640). Following the detection of gamma-ray pulsations using a radio ephemeris, we have obtained a phase-coherent timing solution based on gamma-ray and radio pulse arrival times that spans the entire Fermi mission. With a rotation period of 0.28, spin-down luminosity of 3 x 10(exp 34) erg/s, and characteristic age of 0.5 Myr, PSR J2030+3641 is a middle-aged neutron star with spin parameters similar to those of the exceedingly gamma-ray-bright and radio-undetected Geminga. Its gamma-ray flux is 1 % that of Geminga, primarily because of its much larger distance, as suggested by the large integrated column density of free electrons, DM = 246 pc/cu cm. We fit the gamma-ray light curve, along with limited radio polarimetric constraints, to four geometrical models of magnetospheric emission, and while none of the fits have high significance some are encouraging and suggest that further refinements of these models may be worthwhile. We argue that not many more non-millisecond radio pulsars may be detected along the Galactic plane that are responsible for LAT sources, but that modified methods to search for gamma-ray pulsations should be productive - PSR J2030+364 I would have been found blindly in gamma rays if only > or approx. 0.8 GeV photons had been considered, owing to its relatively flat spectrum and location in a region of high soft background.

Elastic and proton dissociative J/ψ photoproduction at low Wγp with the H1 detector at HERA

International Nuclear Information System (INIS)

Huber, Florian

2013-02-01

Elastic and proton dissociative photoproduction of J/ψ mesons is measured with the H1 detector at the HERA electron proton collider in the photon virtuality phase space of Q 2 2 . Two data sets are analysed, one measured with a nominal proton beam energy of 920 GeV, corresponding to an ep centre of mass energy of 318 GeV and one recorded with a reduced beam energy of 460 GeV, corresponding to an ep centre of mass energy of 225 GeV. The combination of the two data sets allow to perform the J/ψ measurement with central tracks in an extended kinematic phase space in a photon proton centre of mass energy range of 20 GeV γp -1 and 10.8 pb -1 , respectively, corresponding to more than two times the statistics used in previous H1 analyses. Due to an online selection purely based on tracks both leptonic decay channels J/ψ→ee and J/ψ→μμ are available for the analysis. Elastic (γp→ J/ψp) and proton dissociative (γp→ J/ψY) differential γp cross sections are determined in a simultaneous measurement as function of the squared momentum transfer at the proton vertex t and as function of W γp by means of an unfolding procedure, taking not only all bin correlations into account, but also the correlation between the elastic and proton dissociative process. The obtained elastic and proton dissociative differential cross sections are analysed in a simultaneous fit, taking the full statistical covariance matrices and systematic uncertainty sources into account.

Feeding the masses: H.J. Heinz and the creation of industrial food.

The H.J. Heinz Company's commitment to the purity and quality of its products in the late nineteenth and early twentieth century helped usher in an era of industrial food. While canning had been around for decades, it was not until both scientist and technologists innovations solved problems like bacterial contamination and mass-produced cans that Americans began to eat canned food on a regular basis. In addition to money-back guarantees, Heinz pioneered product tastings as a marketing tool in an attempt to convince skeptical housewives that his products were not only delicious, but were also safe to eat.

A search is performed for $D^{(*)+}_{sJ}$ mesons in the reactions $pp \\to D^{*+} K^0_{\\rm S} X$ and $pp \\to D^{*0} K^+ X$ using data collected at centre-of-mass energies of 7 and 8 TeV with the LHCb detector. For the $D^{*+} K^0_{\\rm S}$ final state, the decays $D^{*+} \\to D^0 \\pi^+$ with $D^0 \\to K^- \\pi^+$ and $D^0 \\to K^- \\pi^+ \\pi^+ \\pi^-$ are used. For $D^{*0} K^+$, the decay $D^{*0} \\to D^0 \\pi^0$ with $D^0 \\to K^- \\pi^+$ is used. A prominent $D_{s1}(2536)^+$ signal is observed in both $D^{*+} K^0_{\\rm S}$ and $D^{*0} K^+$ final states. The resonances $D^*_{s1}(2700)^+$ and $D^*_{s3}(2860)^+$ are also observed, yielding information on their properties, including spin-parity assignments. The decay $D^*_{s2}(2573)^+ \\to D^{*+} K^0_{\\rm S}$ is observed for the first time, at a significance of 6.9 $\\sigma$, and its branching fraction relative to the $D^*_{s2}(2573)^+ \\to D^+ K^0_{\\rm S}$ decay mode is measured.
Study of $B_{\\scriptscriptstyle (s)}^0 \\to K_{\\rm \\scriptscriptstyle S}^0 h^{+} h^{\\prime -}$ decays with first observation of $B_{\\scriptscriptstyle s}^0 \\to K_{\\rm \\scriptscriptstyle S}^0 K^{\\pm} \\pi^{\\mp}$ and $B_{\\scriptscriptstyle s}^0 \\to K_{\\rm \\scriptscriptstyle S}^0 \\pi^{+} \\pi^{-}$

A search for charmless three-body decays of $B^0$ and $B_{\\scriptscriptstyle s}^0$ mesons with a $K_{\\rm \\scriptscriptstyle S}^0$ meson in the final state is performed using the $pp$ collision data, corresponding to an integrated luminosity of $1.0\\mathrm{\\,fb}^{-1}$, collected at a centre-of-mass energy of $7\\mathrm{\\,Te\\kern -0.1em V}$ recorded by the LHCb experiment.

In view of the first measurement of the branching fraction for J /ψ →π0e+e- by the BESIII collaboration, we analyze what can be learned on the corresponding transition form factor using dispersion theory. We show that light-quark degrees of freedom dominate the spectral function, in particular two-pion intermediate states. Estimating the effects of multipion states as well as charmonium, we arrive at a prediction for the complete form factor that should be scrutinized experimentally in the future.

We present a Hubble Space Telescope weak-lensing study of the merging galaxy cluster 'El Gordo' (ACT-CL J0102–4915) at z = 0.87 discovered by the Atacama Cosmology Telescope (ACT) collaboration as the strongest Sunyaev-Zel'dovich decrement in its ∼1000 deg{sup 2} survey. Our weak-lensing analysis confirms that ACT-CL J0102–4915 is indeed an extreme system consisting of two massive (≳ 10{sup 15} M {sub ☉} each) subclusters with a projected separation of ∼0.7 h{sub 70}{sup −1} Mpc. This binary mass structure revealed by our lensing study is consistent with the cluster galaxy distribution and the dynamical study carried out with 89 spectroscopic members. We estimate the mass of ACT-CL J0102–4915 by simultaneously fitting two axisymmetric Navarro-Frenk-White (NFW) profiles allowing their centers to vary. We use only a single parameter for the NFW mass profile by enforcing the mass-concentration relation from numerical simulations. Our Markov-Chain-Monte-Carlo analysis shows that the masses of the northwestern (NW) and the southeastern (SE) components are M{sub 200c}=(1.38±0.22)×10{sup 15} h{sub 70}{sup −1} M{sub ⊙} and (0.78±0.20)×10{sup 15} h{sub 70}{sup −1} M{sub ⊙}, respectively, where the quoted errors include only 1σ statistical uncertainties determined by the finite number of source galaxies. These mass estimates are subject to additional uncertainties (20%-30%) due to the possible presence of triaxiality, correlated/uncorrelated large scale structure, and departure of the cluster profile from the NFW model. The lensing-based velocity dispersions are 1133{sub −61}{sup +58} km s{sup −1} and 1064{sub −66}{sup +62} km s{sup −1} for the NW and SE components, respectively, which are consistent with their spectroscopic measurements (1290 ± 134 km s{sup –1} and 1089 ± 200 km s{sup –1}, respectively). The centroids of both components are tightly constrained (∼4'') and close to the optical luminosity
Study of CP violation in the channel Bd0 → J/ψ(ee)KS0, identification and reconstruction of electrons in the LHCb experiment

LHCb experiment has been designed in order to do precise measurements of CP violation and rare decays with B mesons. In 2000, the collaboration decided to modify the spectrometer in order to minimize the amount of matter seen by particles and to optimize the trigger. This thesis was done in this context and is divided into 3 parts. The first part is relative to the electron identification and to the recovery of Bremsstrahlung photons emitted by electrons when they pass through matter. Electron identification is mainly based on information provided by calorimeter system but also uses RICH and muon system. A method based on reference histograms had been developed which combine information provided by these detectors. Electron identification efficiency, for electrons in ECAL acceptance is 95% and the pion mis-identification rates 0.8% with a 65% purity of electron sample. Bremsstrahlung recovery allows the selection of J/φ decaying in e + e - pair and of B d 0 → J/φ(ee)K S 0 channel which are described in the second part. The selection of this channel was developed in order to get an acceptable selection efficiency with a good rejection of background. A set of kinematic and topological cuts were designed and total selection efficiency is 0.176%, corresponding to 28000 untagged events reconstructed by year, with a ratio B/S belonging to [0.017;0.069] (at 90% of confidence level) for inclusive bb-bar background. In the third part, B meson flavour tagging is presented. The addition of information provided by the vertex locator allows to reject electron coming from conversion and to improve slightly the performances. The LHCb sensibility to sin(2β) from B 0 → J/ψK S 0 decay is also determined. The statistical error, expected after one year of data collecting, corresponding to an integrated luminosity of 2 fb -1 and bb-bar pair cross section of 0.5 mb, varies from 0.015 to 0.020 according to the values of sin(2β), |λ f | and B/S.

We present a study of J/{psi} meson production in collisions of 26.7 GeV electrons with 820 GeV protons, performed with the H1-detector at the HERA collider at DESY. The J/{psi} mesons are detected via their leptonic decays both to electrons and muons. Requiring exactly two particles in the detector, a cross section of {sigma}(ep{yields}J/{psi}X)=(8.8{+-}2.0{+-}2.2) nb is determined for 30 GeV{<=}W{sub {gamma}p}{<=}180 GeV and Q{sup 2}< or {approx}4 GeV{sup 2}. Using the flux of quasi-real photons with Q{sup 2}< or {approx}4 GeV{sup 2}, a total photoproduction cross section of {sigma}({gamma}p{yields}J/{psi}X)=(56{+-}13{+-}14) nb is derived at an average W{sub {gamma}p}=90 GeV. The distribution of the squared momentum transfer t from the proton to the J/{psi} can be fitted using an exponential exp(-bvertical stroke tvertical stroke ) below avertical stroke tvertical stroke of 0.75 GeV{sup 2} yielding a slope parameter of b=(4.7{+-}1.9) GeV{sup -2}.

H ii regions are particularly interesting because they can generate dense layers of gas and dust, elongated columns or pillars of gas pointing toward the ionizing sources, and cometary globules of dense gas where triggered star formation can occur. Understanding the interplay between the ionizing radiation and the dense surrounding gas is very important to explain the origin of these peculiar structures, and hence to characterize triggered star formation. G46.5-0.2 (G46), a poorly studied galactic H ii region located at about 4 kpc, is an excellent target for performing this kind of study. Using public molecular data extracted from the Galactic Ring Survey ({sup 13}CO J = 1–0) and from the James Clerk Maxwell Telescope data archive ({sup 12}CO, {sup 13}CO, C{sup 18}O J = 3–2, HCO{sup +}, and HCN J = 4–3), and infrared data from the GLIMPSE and MIPSGAL surveys, we perform a complete study of G46, its molecular environment, and the young stellar objects (YSOs) placed around it. We found that G46, probably excited by an O7V star, is located close to the edge of the GRSMC G046.34-00.21 molecular cloud. It presents a horse-shoe morphology opening in the direction of the cloud. We observed a filamentary structure in the molecular gas likely related to G46 and not considerable molecular emission toward its open border. We found that about 10′ to the southwest of G46 there are some pillar-like features, shining at 8 μm and pointing toward the H ii region open border. We propose that the pillar-like features were carved and sculpted by the ionizing flux from G46. We found several YSOs likely embedded in the molecular cloud grouped in two main concentrations: one, closer to the G46 open border consisting of Class II type sources, and another mostly composed of Class I type YSOs located just ahead of the pillar-like features, strongly suggesting an age gradient in the YSO distribution.

The thermodynamics of the gadolinium-hydrogen (Gd–H) binary system (H/Gd = 0.0–2.0) between 650 and 900 °C is studied by pressure composition isotherm measurement. Significant H dissolution in Gd is observed, up to H/Gd = 0.34 at 650 °C and 0.55 at 900 °C. The metal-rich phase boundary of nonstoichiometric gadolinium dihydride was found to occur with nominal composition of GdH{sub 1.80} at 650 °C and GdH{sub 1.53} at 900 °C. The results are in fairly good agreement with previous experimental work but with improved accuracy. The binary phase diagram is obtained using the CALPHAD method. The thermodynamic study here assists the understanding on the efficient deoxygenation effect by the H in Gd for Gd purification. - Highlights: • PCI measurements with high accuracy has been carried out. • A first assessment of Gd–H system has been carried out by the CALPHAD method. • A set of self-consistent thermodynamic parameters was derived for this system.
Theoretical status of J/ψ suppression

International Nuclear Information System (INIS)

Gavin, S.

High energy heavy ion collisions are expected to produce hadron densities far beyond the density in nuclei, ρ 0 = 0.16 fm -3 . Remarkably, no single measurement from the AGS and SPS light ion programs with projectiles A ≤ 32 stands out as unambiguous evidence of these extreme densities. To separate the high density signals from the background effects that result, e.g. from scattering with primary nucleons, careful systematic studies of hadron-nucleus, hA, and nucleus-nucleus, AB, data are needed. In this talk the author surveys the ongoing systematic study of the most notorious case in point -- J/ψ suppression. In principle, measurements of J/ψ suppression provide a probe of the densities obtained in AB collisions that is also sensitive to quark gluon plasma production. The latest results from SPS experiment NA38 reported by A. Romana in these proceedings show that the ratio of cross sections in the dimuon channel B μμ σ ψ /σ cont is reduced by a factor 0.50 ± 0.05 in central S+U compared to minimum bias pU collisions at 200 AGeV. This is precisely the sort of suppression that one expects if high densities are obtained. On the other hand, a target-mass dependence suggestive of this suppression is found in hA collisions where high densities are not expected. At 200 GeV, NA38 finds that B μμ σ ψ /σ cont falls to 0.84 ± 0.08 in pU compared to pCu. The hA suppression in this kinematic regime is likely due to a combination of nuclear effects: nucleon absorption and shadowing
Investigation of magnetocaloric effect in La0.45Pr0.25Ca0.3MnO3 by magnetic, differential scanning calorimetry and thermal analysis

We investigated magnetocaloric effect in La 0.45 Pr 0.25 Ca 0.3 MnO 3 by direct methods (changes in temperature and latent heat) and indirect method (magnetization isotherms). This compound undergoes a first-order paramagnetic to ferromagnetic transition with T C =200 K upon cooling. The paramagnetic phase becomes unstable and it transforms into a ferromagnetic phase under the application of magnetic field, which results in a field-induced metamagnetic transition (FIMMT). The FIMMT is accompanied by release of latent heat and temperature of the sample as evidenced from differential scanning calorimetry and thermal analysis experiments. A large magnetic entropy change of ΔS m =−7.2 J kg −1 K −1 at T=212.5 K and refrigeration capacity of 228 J kg −1 are found for a field change of ΔH=5 T. It is suggested that destruction of magnetic polarons and growth of ferromagnetic phase accompanied by a lattice volume change with increasing magnetic field is responsible for the large magnetocaloric effect in this compound. - Highlights: ► We report magnetic entropy change measured by indirect and direct methods in La 0.45 Pr 0.25 Ca 0.3 MnO 3. ► Anomalous field-induced induced metamagnetic transition is found in the paramagnetic state. ► A large reversible magnetic entropy change (ΔS m =7.2 J kg −1 K −1 for ΔH=5 T). ► A large refrigeration capacity (RC=228 J kg −1 ). ► Collapse of magnetic polarons is suggested as possible origin of the large MCE.

Measurement of CP violation in $B_s^0\\to J/\\psi \\phi$ decays using the full CDF data set

We report on the final measurement of the CP-violating $B_s^0$ mixing phase $\\beta_s^{J/ψφ}$ in √s = 1.96 TeV proton-antiproton collisions collected with the Collider Detector at the Fermilab Tevatron collider. Using a sample corresponding to 9.6 fb^-1 of integrated luminosity, we fit the decay-time evolution of $B_s^0$ → J/ψ (→ μ⁺ μ^-) φ (→ K⁺ K^₋) decays in which the b-quark content at production and the CP parity of the final state are identified. The interference of decays with and without mixing renders the $B_s^0$ mixing phase observable. The phase is determined to be -0.06 < $\\beta_s^{J/ψφ}$ < 0.30 at 68% confidence level. The decay-width difference between heavy and light $B_s^0$ eigenstates, and the average $B_s^0$ lifetime are also determined to be ΔΓ_s = 0.068 ± 0.027 ps^-1 and $\\tau_s$ = 1.528 ± 0.021 ps, respectively. These results are among the world’s most precise from a single experiment, and compatible with standard model predictions.

LHCb has been designed in order to perform precise measurements of CP violation and rare decays with B mesons. At the LHC start-up, one of the first tasks will be to check the expected apparatus performances. This thesis looks to the first recorded data by the LHCb experiment for two of the subjects developed: the photon reconstruction in the electromagnetic calorimeter assuming different experimental situations, and the calibration of the calorimeter. A photon identification tool is developed based on a Fisher discriminant method using informations from all the calorimeter sub-detectors (SPD, PS, ECAL, HCAL). The reconstructed photons are used for π 0 mass reconstruction parameters, able to evaluate the overall calibration level. For individual cell calibration, the constraint from the reconstructed π 0 mass is used. A 1% calibration can be achieved even starting from a 30% spread cell to cell calibration within a few tenth hours at the LHCb nominal luminosity. Two physics channels, for which the calorimeter calibration and neutral mesons decaying into photon pair reconstruction are key points, are studied. The channel B d 0 →p J/ψπ to measure β angle, where unexpected contributions beyond the standard model may occur. The channel B s 0 → J/ψη measures the χ angle. (author)
Measurement of the CP violating phase β_s in B⁰_s J/ΨΦ decays

The CP violating phase β^j/ΨΦ_s is measured in decays of B⁰_s → J/ΨΦ. This measurement uses 5.2 fb^-1 of data collected in √s = 1.96 TeV p$\\bar{p}$ collisions at the Fermilab Tevatron with the CDF Run-II detector. CP violation in the B_s⁰-$\\bar{B}$_s⁰ system is predicted to be very small in the Standard Model. However, several theories beyond the Standard Model allow enhancements to this quantity by heavier, New Physics particles entering second order weak mixing box diagrams. Previous measurements have hinted at a deviation from the Standard Model expectation value for β_s^J/ΨΦ with a significance of approximately 2σ. The measurement described in this thesis uses the highest statistics sample available to date in the B_s⁰ → J/ΨΦ decay channel, where J/Ψ → μ⁺μ^- and Φ → K⁺K^-. Furthermore, it contains several improvements over previous analyses, such as enhanced signal selection, fully calibrated particle ID and flavour tagging, and the inclusion of an additional decay component in the likelihood function. The added decay component considers S-wave states of KK pairs in the B_s⁰ → J/Ψ K⁺K^- channel. The results are presented as 2-dimensional frequentist confidence regions for β_s^J/ΨΦ and ΔΓ (the width difference between the B_s⁰ mass eigenstates), and as a confidence interval for β_s^J/ΨΦ of [0.02,0.52] U [1.08, 1.55] at the 68% confidence level. The measurement of the CP violating phase obtained in this thesis is complemented by the world's most precise measurement of the lifetime τ_s = 1.53 ± 0.025 (stat.) ± 0.012 (syst.) ps and decay width difference ΔΓ = 0.075 ± 0.035 (stat.) ± 0.01 (syst.) ps^-1 of the B

The resonant structure of the decay $\\overline{B}_s^0\\to J/\\psi\\pi^+\\pi^-$ is studied using data corresponding to 3 fb$^{-1}$ of integrated luminosity from $pp$ collisions by the LHC and collected by the LHCb detector. Five interfering $\\pi^+\\pi^-$ states are required to describe the decay: $f_0(980),~f_0(1500),~f_0(1790),~f_2(1270)$, and $f_2^{\\prime}(1525)$. An alternative model including these states and a non-resonant $J/\\psi \\pi^+\\pi^-$ component also provides a good description of the data. Based on the different transversity components measured for the spin-2 intermediate states, the final state is found to be compatible with being entirely $CP$-odd. The $CP$-even part is found to be $<2.3$% at 95% confidence level. The $f_0(500)$ state is not observed, allowing a limit to be set on the absolute value of the mixing angle with the $f_0(980)$ of $<7.7^{\\circ}$ at 90% confidence level, consistent with a tetraquark interpretation of the $f_0(980)$ substructure.

Polycrystalline NdFeAsO 0.88 F 0.12 superconductors prepared by high pressure (HP) and ambient pressure (AP) methods were comparatively studied by magnetization and transport measurements. Upper critical field H c2 , irreversibility field H irr and the anisotropy parameter Γ were estimated from resistance transition curves. The broadening of transition width was observed, and was ascribed to both H c2 anisotropy and superconductivity inhomogeneity of samples. Magnetic hysteresis loops (MHLs) in low fields were measured to detect the trace of weak-link behavior. The reclosed hysteresis loops in low fields indicate that there are weak links in both samples. Magnetization critical current density J cm were derived from MHLs. Sample HP shows higher J cm than sample AP. Direct transport I-V measurements show that the transport critical current density J ct are very low but persist up to 9 T, suggesting intrinsic strong-link existing in both samples.

The frustrated spin-1/2 J 1 -J 2 -J 3 antiferromagnet with exchange anisotropy on the two-dimensional square lattice is investigated. The exchange anisotropy is presented by η with 0 ≤ η J 1 , J 2 , J 3 and anisotropy on the possible phase transition of the Néel state and collinear state are studied comprehensively. Our results indicate that for J 3 > 0 there are upper limits [Formula: see text] and η c values. When 0 J 3 ≤ [Formula: see text] and 0 ≤ η ≤ η c , the Néel and collinear states have the same order-disorder transition point at J 2 = J 1 /2. Nevertheless, when the J 3 and η values beyond the upper limits, it is a paramagnetic phase at J 2 = J 1 /2. For J 3 J 2 = J 1 /2. Therefore, for J 2 = J 1 /2, under such parameters, a first-order phase transition between the two states for these two cases below the critical temperatures may occur. When J 2 ≠ J 1 /2, the Néel and collinear states may also exist, while they have different critical temperatures. When J 2 > J 1 /2, a first-order phase transition between the two states may also occur. However, for J 2 J 1 /2, the Néel state is always more stable than the collinear state.

Magnetic resonance spectroscopy (MRS) is a powerful tool capable of investigating the metabolic status of several tissues in vivo. In particular, single-voxel-based 1 H spectroscopy provides invaluable biochemical information from a volume of interest (VOI) and has therefore been used in a variety of studies. Unfortunately, typical one-dimensional MRS data suffer from severe signal overlap and thus important metabolites are difficult to distinguish. One method that is used to disentangle overlapping resonances is the two-dimensional J-resolved spectroscopy (JPRESS) experiment. Due to the long acquisition duration of the JPRESS experiment, a limited number of points are acquired in the indirect dimension, leading to poor spectral resolution along this dimension. Poor spectral resolution is problematic because proper peak assignment may be hindered, which is why the zero-filling method is often used to improve resolution as a post-processing step. However, zero-filling leads to spectral artifacts, which may affect visualization and quantitation of spectra. A novel method utilizing a covariance transformation, called covariance J-resolved spectroscopy (CovJ), was developed in order to improve spectral resolution along the indirect dimension (F 1 ). Comparison of simulated data demonstrates that peak structures remain qualitatively similar between JPRESS and the novel method along the diagonal region (F 1 = 0 Hz), whereas differences arise in the cross-peak (F 1 ≠0 Hz) regions. In addition, quantitative results of in vivo JPRESS data acquired on a 3T scanner show significant correlations (r 2 >0.86, pCOVariance Spectral Evaluation of 1 H Acquisitions using Representative prior knowledge' (Cov-SEHAR), was developed in order to quantify γ-aminobutyric acid and glutamate from the CovJ spectra. These preliminary findings indicate that the CovJ method may be used to improve spectral resolution without hindering metabolite quantitation for J-resolved spectra

Measurements of $b$-hadron lifetimes are reported using $pp$ collision data, corresponding to an integrated luminosity of 1.0fb$^{-1}$, collected by the LHCb detector at a centre-of-mass energy of $7$Tev. Using the exclusive decays $B^+\\to J/\\psi K^+$, $B^0\\to J/\\psi K^*(892)^0$, $B^0\\to J/\\psi K^0_{\\rm S}$, $\\Lambda_b^0\\to J/\\psi \\Lambda$ and $B^0_s\\to J/\\psi \\phi$ the average decay times in these modes are measured to be $\\tau_{B^+\\to J/\\psi K^+}$ = $1.637 \\pm$ 0.004 $\\pm$ 0.003 ps, $\\tau_{B^0\\to J/\\psi K^*(892)^0}$ = $1.524 \\pm$ 0.006 $\\pm$ 0.004 ps, $\\tau_{B^0\\to J/\\psi K^0_{\\rm S}}$ = $1.499 \\pm$ 0.013 $\\pm$ 0.005 ps, $\\tau_{\\Lambda_b^0\\to J/\\psi \\Lambda}$ = $1.415 \\pm$ 0.027 $\\pm$ 0.006 ps and $\\tau_{B^0_s\\to J/\\psi \\phi}$ = $1.480 \\pm$ 0.011 $\\pm$ 0.005 ps, where the first uncertainty is statistical and the second is systematic.

In the B s 0 → ψφ channel, the phase φ s is predicted to be significantly small in the Standard Model. This observable is an excellent probe for New Physics because the B s 0 -B-bar s 0 mixing takes place via a loop diagram where new particles are expected to intervene. These two reasons makes the φ s parameter an excellent probe for New Physics processes. We developed a simplified selection for the 2010 data. It avoids any bias on the proper time distribution in order to reduce systematic uncertainty. In addition, we control the tagging performance for B s 0 → J/ψφ events using the similar B d 0 → J/ψK *0 and B + → J/ψK + channels. With the 2010 data, we obtain 570 signal events in 36 pb -1 of integrated luminosity, a tagging power of (2.2 ± 0.4)% and a proper time resolution of 50 fs. We investigated an alternative selection which maximizes the φs sensitivity using a proper time biasing cuts. We proposed a data-driven method to correct the proper time acceptance. We designed a fitting program to determine the φ s phase. With the 2010 data, it is found to be: φ s belongs to [-2.7, -0.5] rad at 68% of confidence. This result is compatible with the Standard Model prediction. (author)

A search for direct $CP$ violation in $D^0\\rightarrow h^-h^+$ (where $h=K$ or $\\pi$) is presented using data corresponding to an integrated luminosity of 1.0 fb$^{-1}$ collected in 2011 by LHCb in $pp$ collisions at a centre-of-mass energy of 7 TeV. The analysis uses $D^0$ mesons produced in inclusive semileptonic $b$-hadron decays to the $D^0\\mu X$ final state, where the charge of the accompanying muon is used to tag the flavour of the $D^0$ meson. The difference in the $CP$-violating asymmetries between the two decay channels is measured to be \\begin{equation} \\Delta A_{CP} = A_{CP}(K^-K^+)-A_{CP}(\\pi^-\\pi^+) = (0.49\\pm 0.30\\,\\rm{(stat)} \\pm 0.14\\,\\rm{(syst)})\\% \\ . \

Cadmium is expected to be the solvent for pyrochemical processing of the metallic nuclear fuel. Therefore, thermodynamic properties of cadmium with various fuel and clad elements are of interest. Enthalpies of formation of the intermetallic compounds of Cd-Sr system, Cd 0.917 Sr 0.083 , Cd 0.857 Sr 0.143 and Cd 0.667 Sr 0.333 were determined by precipitation using Calvet calorimeter. Enthalpies of formation of the compounds were found to be -3.05 ± 0.5 kJ mol -1 at 723 K, -14.2 ± 0.7 kJ mol -1 at 843 K and -28.4 ± 0.8 kJ mol -1 at 863 K, respectively. Enthalpies of formation of Cd 0.917 Sr 0.083 and Cd 0.857 Sr 0.143 were also determined by partial enthalpy of formation measurements and the values were found to be -3.9 ± 1.1 kJ mol -1 at 723 K and -13.42 ± 1.2 kJ mol -1 at 843 K, respectively. Miedema model was used to estimate the enthalpies of formation of these compounds and the estimated values were compared with the experimentally determined values

Low J rotational transitions of 4 HeH + , 4 HeD + , 3 HeH + , and 3 HeD + were observed in the 2 endash 5THz region with a high-precision far-infrared spectrometer. Dunham coefficients Y kl and isotopically independent parameters U kl , Δ He kl , and Δ H kl were determined. In particular, Δ parameters with k=0 and l=1,2 were determined with unprecedented accuracy, and provide important information for breakdown of the Born-Oppenheimer approximation. The lowest J=1 left-arrow 0 transition of 4 HeH + observed at 2010.1839(2)GHz will be an important future probe for detecting this species in space. copyright 1997 The American Physical Society
A study of B(s)0 to J/psi phi in the D0 experiment and an example of HEP technology transfer

After years of preparation, data taking with the upgraded D0 detector at the Tevatron proton-antiproton collider has begun. The large amount of data produced in a p(bar p)-collider requires sophisticated triggers to filter out the interesting events. Described in this thesis is the development of trigger software for the newly implemented Silicon Microstrip Tracker. D0 is a multi-purpose detector with a broad physics program. One area being studied at D0 is B mesons. An algorithm for reconstructing the B s 0 and B d 0 mesons and for measuring their lifetimes has been developed and is described in this thesis. The results suggest that an improvement of the current lifetime measurements can be achieved within the next two years. The reconstruction of a J/ψ meson forms the basis for a wide range of b-physics. Data taken with the muon system during the commissioning period of the detector has been analyzed and a signal for the J/ψ meson has been found. Systematic transfer of HEP technologies into other areas and their commercial exploitation will play an important role in the future of particle physics. An area of particular interest is DNA sequencing as shown by the recent completion of the sequencing of the human genome. The final part of this thesis details the development of a simulation for a high throughput sequencing device which is currently being developed at Imperial College
Search for CP violation in BS0 → J/ψφ

The CDF experiment, which uses p(bar p) collisions at √s = 1.9 TeV produced at the Fermilab Tevatron, is unique in its ability to observe all flavors of B hadrons and measure their properties. Among them, CP violation is of fundamental interest. In the B + and B 0 systems, measurements of CP violation parameters performed essentially at B factories have borne out the predictions of CKM model. Little is known, experimentally, about CP violation in the B s 0 system. The standard model predicts very little CP violation there, thus any nonzero measurement could be an indication of new physics. In this thesis, we will report on the very first flavor-tagged analysis of approximately 2000 B s 0 → J/ψφ decays reconstructed in a 1.35 fb -1 data sample collected at CDF. This channel is sensitive not only to the width difference ΔΛ in the B s 0 system but also to the CP violation parameter β s . The final result we obtain is a confidence region in the two dimensional space of β s and ΔΛ. Assuming the standard model predictions of β s and ΔΛ, the probability is 15%, corresponding to 1.5 Gaussian standard deviations

An amplitude analysis of the final state structure in the $\\overline{B}_s^0 \\to J/\\psi K^+K^-$ decay mode is performed using $1.0~\\rm fb^{-1}$ of data collected by the LHCb experiment in 7 TeV center-of-mass energy $pp$ collisions produced by the LHC. A modified Dalitz plot analysis of the final state is performed using both the invariant mass spectra and the decay angular distributions. Resonant structures are observed in the $K^+K^-$ mass spectrum as well as a significant non-resonant S-wave contribution. The largest resonant component is the $\\phi(1020)$, accompanied by $f_0(980)$, $f_2'(1525)$, and four additional resonances. The overall branching fraction is measured to be $\\mathcal{B}(\\overline{B}_s^0 \\to J/\\psi K^+K^-)=(7.70\\pm0.08\\pm 0.39\\pm 0.60)\\times 10^{-4}$, where the first uncertainty is statistical, the second systematic, and the third due to the ratio of the number of $\\overline{B}_s^0$ to $B^-$ mesons produced. The mass and width of the $ f_2'(1525)$ are measured to be $1522.2\\pm 2.8^{+5....

The Tambaqui is a model neotropical teleost which is of great economic and cultural importance in artisanal fisheries and commercial aquaculture. It thrives in ion-poor, often acidic Amazonian waters and exhibits excellent regulation of physiology down to water pH 4.0. Curiously, however, it is reported to perform poorly in aquaculture at pH 8.0, an only slightly alkaline pH which would be benign for most freshwater fish. In initial experiments with Tambaqui of intermediate size (30-50 g), we found that ammonia excretion rate was unchanged at pH 4, 5, 6, and 7, but elevated after 20-24 h at pH 8, exactly opposite the pattern seen in most teleosts. Subsequent experiments with large Tambaqui (150-300 g) demonstrated that only ammonia, and not urea excretion was increased at pH 8.0, and that the elevation was proportional to a general increase in MO 2 . There was an accompanying elevation in net acidic equivalent excretion and/or basic equivalent uptake which occurred mainly at the gills. Net Na + balance was little affected while Cl - balance became negative, implicating a disturbance of Cl - versus base exchange rather than Na + versus acid exchange. Arterial blood pH increased by 0.2 units at pH 8.0, reflecting combined metabolic and respiratory alkaloses. Most parameters recovered to control levels by 18-24 h after return to pH 6.0. With respect to large Tambaqui, we conclude that a physiology adapted to acidic pH performs inappropriately at moderately alkaline pH. In small Tambaqui (4-15 g), the responses were very different, with an initial inhibition of ammonia excretion rate at pH 8.0 followed by a subsequent restoration of control levels. Elevated ammonia excretion rate occurred only after return to pH 6.0. Furthermore, MO 2 , plasma cortisol, and branchial vH + ATPase activities all declined during pH 8.0 exposure in small Tambaqui, in contrast to the responses in larger fish. Overall, small Tambaqui appear to cope better at pH 8.0, a difference that
A Chebyshev method for state-to-state reactive scattering using reactant-product decoupling: OH + H2 → H2O + H.

We extend a recently developed wave packet method for computing the state-to-state quantum dynamics of AB + CD → ABC + D reactions [M. T. Cvitaš and S. C. Althorpe, J. Phys. Chem. A 113, 4557 (2009)] to include the Chebyshev propagator. The method uses the further partitioned approach to reactant-product decoupling, which uses artificial decoupling potentials to partition the coordinate space of the reaction into separate reactant, product, and transition-state regions. Separate coordinates and basis sets can then be used that are best adapted to each region. We derive improved Chebyshev partitioning formulas which include Mandelshtam-and-Taylor-type decoupling potentials, and which are essential for the non-unitary discrete variable representations that must be used in 4-atom reactive scattering calculations. Numerical tests on the fully dimensional OH + H2 → H2O + H reaction for J = 0 show that the new version of the method is as efficient as the previously developed split-operator version. The advantages of the Chebyshev propagator (most notably the ease of parallelization for J > 0) can now be fully exploited in state-to-state reactive scattering calculations on 4-atom reactions.

Highlights: • We report calculation of the exact rovibrational energy levels of SO{sub 2} for J = 0–10. • We report sulfur isotope shifts of the SO{sub 2} isotopologues rovibrational frequencies. • Coriolis coupling is treated exactly. • All rovibrational levels are computed to a high level of numerical convergence. • All of the rovibrational data exhibit near-perfect mass-dependent fractionation. - Abstract: Isotopic variation of the rovibrational bound states of SO{sub 2} for the four stable sulfur isotopes {sup 32–34,36}S is investigated in comprehensive detail. In a two-part series, we compute the low-lying energy levels for all values of total angular momentum in the range J = 0–20. All rovibrational levels are computed, to an extremely high level of numerical convergence. The calculations have been carried out using the ScalIT suite of parallel codes. The present study (Paper I) examines the J = 0–10 rovibrational levels, providing unambiguous symmetry and rovibrational label assignments for each computed state. The calculated vibrational energy levels exhibit very good agreement with previously reported experimental and theoretical data. Rovibrational energy levels, calculated without any Coriolis approximations, are reported here for the first time. Among other potential ramifications, this data will facilitate understanding of the origin of mass-independent fractionation of sulfur isotopes in the Archean rock record—of great relevance for understanding the “oxygen revolution”.

A high resolution detector for H0 → γγ

SSC detectors represent a challenging departure, both in size and precision, from currently operating detectors. In this note we enumerate some of the benefits of using high magnetic fields both to simplify the detector and improve its resolution and sensitivity. We have chosen an arrangement optimized to search for the reaction H 0 → γγ. The arrangement also has the excellent momentum resolution for muons and electrons considered critical for the discovery of such processes as H 0 → Z 0 Z 0 → ell + ell - ell + ell - , H 0 → Z 0 Z 0 → ell + ell - ell + ell - , new and narrow vector bosons, and bound states of extra generational quarks. This detection scheme represents an improvement in the H 0 → γγ mass resolution of at least a factor of 7 beyond the best currently proposed detectors. In addition, we have a significantly improved rejection of common H 0 → γγ backgrounds. As indeed most experiments do not exceed their initial projections, this extra factor could insure the unambiguous discovery of this decay should it indeed occur. As no reasonably realistic detector can achieve excellent detection for all physics signatures we chose to give tip on excellent hadron calorimetry. For Higgs masses between 80 and 150 GeV/c 2 the Higgs decay into two photons is an excellent signature. To date, all attempts to search for this decay mode have centered on the use of electromagnetic calorimetry. We are proposing a different approach. We will convert the two photons close to the production point and measure the momenta of the electron pairs

To understand and simulate the dynamics behavior of the title reaction, QCT calculations were performed on a recently developed global analytical potential energy surface, PES-2017. These calculations combine the classical description of the dynamics with pseudoquantization in the reactants and products to perform a theoretical/experimental comparison on the same footing. Thus, in the products a series of constraints are included to analyze the HCl(v = 0,j) product, which is experimentally detected. At collision energies of 5.5 and 6.7 kcal mol -1 the largest fraction of available energy is deposited as translation, 67%, while the ethyl radical shows significant internal energy, 27%, and so it does not act as a spectator of the reaction, thus reproducing recent experimental evidence. The HCl(v=0, j) rotational distribution is cold, peaking at j = 2, only one unit hotter than experiment, which represents an error of 0.12 kcal mol -1 . At a collision energy of 5.5 kcal mol -1 product translational distribution is slightly hotter than experiment, but at 6.7 kcal mol -1 agreement with recent experiments is practically quantitative, suggesting that the first experiments should be revised. In addition, we observe that the HCl(v=0, j) scattering distribution shifts from isotropic at low values of j to backward at high values of j, which is in agreement with experimental data. Finally, no evidence was found for the "chattering" mechanism suggested to explain the low translational energy of the HCl product in the backward scattering region. In sum, agreement with experiments of a series of sensible dynamic properties permits us to be optimistic on the quality and accuracy of the theoretical tools used in the present work, QCT and PES-2017.

Detailed studies of I2(β1 g , v β = 13, J β ∼ D{0}u+, v D = 12, J D and D, 48, J D ∼ β, 47, J β ) rovibronic state coupling have been carried out using two-step two-color, hν 1 + hν 2 and hν 1 + 2hν 2, optical–optical double resonance excitation schemes, respectively. The hyperfine interaction satisfying the | {{Δ }}J| = 0, 1 selection rules (magnetic-dipole interaction) has been observed. No electric-quadrupole hyperfine coupling (| {{Δ }}J| = 2) has been found. The dependences of ratios of luminescence intensities from the rovibronic states populated due to the hyperfine coupling to those from optically populated ones on energy gaps between these states have been experimentally determined. The matrix elements as well as the hyperfine structure constant have been obtained using these dependences. It is shown that they increase slightly with the vibrational quantum number of the states.

A measurement of the number of J/ψ events collected with the BESIII detector in 2009 and 2012 is performed using inclusive decays of the J/ψ. The number of J/ψ events taken in 2009 is recalculated to be (223.7 ± 1.4) × 106, which is in good agreement with the previous measurement, but with significantly improved precision due to improvements in the BESIII software. The number of J/ψ events taken in 2012 is determined to be (1086.9 ± 6.0) × 106. In total, the number of J/ψ events collected with the BESIII detector is measured to be (1310.6 ± 7.0) × 106, where the uncertainty is dominated by systematic effects and the statistical uncertainty is negligible.

We demonstrate that dispersion theory allows one to deduce crucial information on πη scattering from the final-state interactions of the light mesons visible in the spectral distributions of the decays B̄ d 0 →J/ψ(π 0 η,K + K − ,K 0 K̄ 0 ). Thus high-quality measurements of these differential observables are highly desired. The corresponding rates are predicted to be of the same order of magnitude as those for B̄ d 0 →J/ψπ + π − measured recently at LHCb, letting the corresponding measurement appear feasible.

We have studied the effect of Fe substitution on magnetic and magnetocaloric properties in La{sub 0.7}Sr{sub 0.3}Mn{sub 1-x}Fe{sub x}O{sub 3} (x=0.05, 0.07, 0.10, 0.15, and 0.20) over a wide temperature range (T=10-400 K). It is shown that substitution by Fe gradually decreases the ferromagnetic Curie temperature (T{sub C}) and saturation magnetization up to x=0.15 but a dramatic change occurs for x=0.2. The x=0.2 sample can be considered as a phase separated compound in which both short-range ordered ferromagnetic and antiferromagnetic phases coexist. The magnetic entropy change (-{Delta}S{sub m}) was estimated from isothermal magnetization curves and it decreases with increase of Fe content from 4.4 J kg{sup -1} K{sup -1} at 343 K (x=0.05) to 1.3 J kg{sup -1} K{sup -1} at 105 K (x=0.2), under {Delta}H=5 T. The La{sub 0.7}Sr{sub 0.3}Mn{sub 0.93}Fe{sub 0.07}O{sub 3} sample shows negligible hysteresis loss, operating temperature range over 60 K around room temperature with refrigerant capacity of 225 J kg{sup -1}, and magnetic entropy of 4 J kg{sup -1} K{sup -1} which will be an interesting compound for application in room temperature refrigeration. - Research highlights: > We report magnetocaloric effect in La{sub 0.7}Sr{sub 0.3}Mn{sub 1-x}Fe{sub x}O{sub 3} (x=0-0.2). > Magnetic entropy change ({Delta}S{sub m}) decreases with increasing x. > A large {Delta}S{sub m} and refrigeration capacity are found around 300 K in x=0.07.

We report the discovery of an unusual stellar system SMSS J130522.47-293113.0. The optical spectrum is dominated by a blue continuum together with emission lines of hydrogen, neutral, and ionized helium, and the N III, C III blend at ˜4640-4650 Å. The emission-line profiles vary in strength and position on time-scales as short as 1 d, while optical photometry reveals fluctuations of as much as ˜0.2 mag in g on time-scales as short as 10-15 min. The system is a weak X-ray source (f0.3-10 = (1.2 ± 0.1) × 10-13 ergs cm2 s-1 in the 0.3-10 keV band) but is not detected at radio wavelengths (3σ upper limit of 50 μJy at 5.5 GHz). The most intriguing property of the system, however, is the existence of two `blobs', a few arcsec in size, that are symmetrically located 3{^'.}8 (2.2 pc for our preferred system distance of ˜2 kpc) each side of the central object. The blobs are detected in optical and near-IR broad-band images but do not show any excess emission in H α images. We discuss the interpretation of the system, suggesting that the central object is most likely a nova-like CV, and that the blobs are relics of a pc-scale accretion-powered collimated outflow.
High accuracy results for the energy levels of the molecular ions H+2, D+2 and HD+, up to J = 2

We present a nonrelativistic calculation of the rotation-vibration levels of the molecular ions H + 2 , D + 2 and HD + , relying on the diagonalization of the exact three-body Hamiltonian in a variational basis. The J = 2 levels are obtained with a very high accuracy of 10 -14 au (for most levels) representing an improvement by five orders of magnitude over previous calculations. The accuracy is also improved for the J = 1 levels of H + 2 and D + 2 with respect to earlier works. Moreover, we have computed the sensitivities of the energy levels with respect to the mass ratios, allowing these levels to be used for metrological purposes

Observation of H-bond mediated 3hJH2H3coupling constants across Watson-Crick AU base pairs in RNA

3h J H2H3 trans-hydrogen bond scalar coupling constants have been observed for the first time in Watson-Crick AU base pairs in uniformly 15 N-labeled RNA oligonucleotides using a new 2h J NN -HNN-E. COSY experiment. The experiment utilizes adenosine H2 (AH2) for original polarization and detection, while employing 2h J NN couplings for coherence transfer across the hydrogen bonds (H-bonds). The H3 protons of uracil bases are unperturbed throughout the experiment so that these protons appear as passive spins in E. COSY patterns. 3h J H2H3 coupling constants can therefore be accurately measured in the acquisition dimension from the displacement of the E. COSY multiplet components, which are separated by the relatively large 1 J H3N3 coupling constants in the indirect dimension of the two-dimensional experiment. The 3h J H2H3 scalar coupling constants determined for AU base pairs in the two RNA hairpins examined here have been found to be positive and range in magnitude up to 1.8 Hz. Using a molecular fragment representation of an AU base pair, density functional theory/finite field perturbation theory (DFT/FPT) methods have been applied to attempt to predict the relative contributions of H-bond length and angular geometry to the magnitude of 3h J H2H3 coupling constants. Although the DFT/FPT calculations did not reproduce the full range of magnitude observed experimentally for the 3h J H2H3 coupling constants, the calculations do predict the correct sign and general trends in variation in size of these coupling constants. The calculations suggest that the magnitude of the coupling constants depends largely on H-bond length, but can also vary with differences in base pair geometry. The dependency of the 3h J H2H3 coupling constant on H-bond strength and geometry makes it a new probe for defining base pairs in NMR studies of nucleic acids

We present new extinction maps and high-resolution Paschen-alpha images of G-0.02-0.07, a complex of compact H II regions located adjacent to the M-0.02-0.07 giant molecular cloud, 6 pc in projection from the center of the Galaxy. These H II regions, which lie in projection just outside the boundary of the Sgr A East supernova remnant, represent one of the most recent episodes of star formation in the central parsecs of the Galaxy. The 1.87 μm extinctions of regions A, B, and C are almost identical, approximately 3.7 mag. Region D, in contrast, has a peak extinction of A 1.87 = 5.9 mag. Adopting an extinction law specific to the Galactic center, we find that these extinctions correspond to visual extinctions of A V = 45 and A V = 71. The similar and uniform extinctions of regions A, B, and C are consistent with that expected for foreground extinction in the direction of the Galactic center, suggesting that they lie at the front side of the M-0.02-0.07 molecular cloud. Region D is more compact, has a higher extinction, and is thus suspected to be younger and embedded in a dense core in a compressed ridge on the western edge of this cloud.

We report on γ-ray analysis of the region containing the bright TeV source HESS J1640–465 and the close-by TeV source HESS J1641–463 using 64 months of observations with the Fermi Large Area Telescope (LAT). Previously only one GeV source was reported in this region and was associated with HESS J1640–465. With an increased data set and the improved sensitivity afforded by the reprocessed data (P7REP) of the LAT, we now report the detection, morphological study, and spectral analysis of two distinct sources above 100 MeV. The softest emission in this region comes from the TeV source HESS J1641–463 which is well fitted with a power law of index Γ = 2.47 ± 0.05 ± 0.06 and presents no significant γ-ray signal above 10 GeV, which contrasts with its hard spectrum at TeV energies. The Fermi-LAT spectrum of the second TeV source, HESS J1640–465 is well described by a power-law shape of index Γ = 1.99 ± 0.04 ± 0.07 that links up naturally with the spectral data points obtained by the High Energy Stereoscopic System (H.E.S.S.). These new results provide new constraints concerning the identification of these two puzzling γ-ray sources.

Magnesium hydride (MgH 2 ) is a hydrogen storage material that operates at temperatures above 300 °C. Unfortunately, magnesium sintering occurs above 420 °C, inhibiting its application as a thermal energy storage material. In this study, the substitution of fluorine for hydrogen in MgH 2 to form a range of Mg(H x F 1-x ) 2 (x = 1, 0.95, 0.85, 0.70, 0.50, 0) composites has been utilised to thermodynamically stabilise the material, so it can be used as a thermochemical energy storage material that can replace molten salts in concentrating solar thermal plants. These materials have been studied by in situ synchrotron X-ray diffraction, differential scanning calorimetry, thermogravimetric analysis, temperature-programmed-desorption mass spectrometry and Pressure-Composition-Isothermal (PCI) analysis. Thermal analysis has determined that the thermal stability of Mg-H-F solid solutions increases proportionally with fluorine content, with Mg(H 0.85 F 0.15 ) 2 having a maximum rate of H 2 desorption at 434 °C, with a practical hydrogen capacity of 4.6 ± 0.2 wt% H 2 (theoretical 5.4 wt% H 2 ). An extremely stable Mg(H 0.43 F 0.57 ) 2 phase is formed upon the decomposition of each Mg-H-F composition of which the remaining H 2 is not released until above 505 °C. PCI measurements of Mg(H 0.85 F 0.15 ) 2 have determined the enthalpy (ΔH des ) to be 73.6 ± 0.2 kJ mol -1 H 2 and entropy (ΔS des ) to be 131.2 ± 0.2 J K -1 mol -1 H 2 , which is slightly lower than MgH 2 with ΔH des of 74.06 kJ mol -1 H 2 and ΔS des = 133.4 J K -1 mol -1 H 2 . Cycling studies of Mg(H 0.85 F 0.15 ) 2 over six absorption/desorption cycles between 425 and 480 °C show an increased usable cycling temperature of ∼80 °C compared to bulk MgH 2 , increasing the thermal operating temperatures for technological applications.

To investigate the changes of Apo-J and Omi/HtrA2 protein expression in rats with intracerebral hemorrage. 150 SD adult rats were randomly divided into 3 groups: (1) Normal Control (NC) group, (2) Sham group, (3) Intracerebral Hemorrage (ICH) group. The data were collected at 6h, 12h, 1d, 2d, 3d, 5d and 7d. Apoptosis was measured by Tunel staining. The distributions of the Apo-J and Omi/HtrA2 proteins were determined by immunohistochemical staining. The levels of Apo-J mRNA and Omi/HtrA2 mRNA expressions were examined by RT-PCR. Apoptosis in ICH group was higher than Sham and NC groups (p＜0.05). Both the Apo-J and Omi/HtrA2 expression levels were increased in the peripheral region of hemorrhage, with a peak at 3d. The Apo-J mRNA level positively correlated with HtrA2 mRNA level in ICH group (r=0.883, p＜0.001). The expressions of Apo-J and Omi/HtrA2 paralelly increased in peripheral region of rat cerebral hemorrhage. Local high expressed Apo-J in the peripheral regions might play a neuroprotective role by inhibiting apoptosis via Omi/HtrA2 pathway after hemorrhage. Copyright © 2018. Published by Elsevier Inc.
Surface charges and J H Poynting’s disquisitions on energy transfer in electrical circuits

Science.gov (United States)

Matar, M.; Welti, R.

2017-11-01

In this paper we review applications given by J H Poynting (1884) on the transfer of electromagnetic energy in DC circuits. These examples were strongly criticized by O Heaviside (1887). Heaviside stated that Poynting had a misconception about the nature of the electric field in the vicinity of a wire through which a current flows. The historical review of this conflict and its resolution based on the consideration of electrical charges on the surface of the wires can be useful for student courses on electromagnetism or circuit theory.
Comment on 'A schematic model of crater modification by gravity' by H. J. Melosh

Pike, R.J.

1983-01-01

Size-dependent variations in the morphology of impact craters on planets and satellites pose controversial problems. H. J. Melosh has continued to emphasize theoretical analysis in modeling the morphologic transition from simple to complex craters. His latest results [Melosh, 1982] outline a comprehensive hypothesis wherein deep-seated collapse of the transient cavity as a Bingham plastic material to produce central peaks and, seemingly, slump terraces is brought about by acoustic fluidization. However, Melosh's paper also contains inconsistent or ambiguously reported observations and some statements and interpretations that need to be clarified

A comparison of the rates for ψ(2S)→π + π - J/ψ, J/ψ→l + l - and J/ψ→ anything is used to determine the J/ψ leptonic branching fractions. The results are B(J/ψ→e + e - )=(5.90±0.05±0.10)% and B(J/ψ→μ + μ - )=(5.84±0.06±0.10)%, where the first error is statistical and the second is systematic. Assuming lepton universality, the leptonic branching fraction of the J/ψ is B(J/ψ→l + l - )=(5.87±0.04±0.09)% per species. This result is used to estimate the QCD scale factor Λ MS (4) and the strong coupling constant α s . copyright 1998 The American Physical Society
A study of B$0\\atop{s}$ → J/ΨΦ in the D0 experiment and an example of HEP technology transfer

Energy Technology Data Exchange (ETDEWEB)

Bauer, Daniela Ursula [Imperial College, London (United Kingdom)

After years of preparation, data taking with the upgraded D0 detector at the Tevatron proton-antiproton collider has begun. The large amount of data produced in a p$\\bar{p}$-collider requires sophisticated triggers to filter out the interesting events. Described in this thesis is the development of trigger software for the newly implemented Silicon Microstrip Tracker. D0 is a multi-purpose detector with a broad physics program. one area being studied at D0 is B mesons. An algorithm for reconstructing the B$0\\atop{s}$ and B$0\\atop{d}$ mesons and for measuring their lifetimes has been developed and is described in this thesis. The results suggest that an improvement of the current lifetime measurements can be achieved within the next two years. The reconstruction of a J/Ψ meson forms the basis for a wide range of b-physics. Data taken with the muon system during the commissioning period of the detector has been analyzed and a signal for the J/Ψ meson has been found. Systematic transfer of HEP technologies into other areas and their commercial exploitation plays an important role in the future of particle physics. An area of particular interest is DNA sequencing as shown by the recent completion of the sequencing of the human genome. The final part of this thesis details the development of a simulation for a high throughput sequencing device which is currently being developed at Imperial College.

La 0.7 Ca 0.3−x Ba x MnO 3 nanoparticles with the crystalline size d = 38 and 39 nm for x = 0.025, and 0.05, respectively, were synthesized by utilizing the solid-state reaction and mechanical ball milling methods. We have used the Banerjee's criteria, the mean-field, and the thermodynamic theories, and isothermal magnetization, M(H), data around Curie temperature (T C ) to investigate the magnetic phase transformation and the temperature (T) and magnetic field (H) dependences of magnetic entropy change, ΔS m (T, H), for nanoparticles. These exhibit the samples undergoing a second-order magnetic phase transition with an existence of the short-range ferromagnetic order in the samples. Under an applied magnetic field change ΔH = 30 kOe, the maximum value of ΔS m (denoted as |ΔS max |) are obtained about 4.4 J kg −1 K −1 corresponding to a relative cooling power (RCP) value about 140 J kg −1 . Field dependences of |ΔS max | and RCP can be expressed by the power laws, |ΔS max | = a × H n and RCP = b × H N , where a and b are coefficients, n and N are the field exponents, respectively. Interestingly, all the ΔS m (T, H) curves measured at different applied fields are collapsed onto a universal curve, ΔS m (T, H)/ΔS max versus θ = (T − T C )/(T r − T C ), where T r is the reference temperature. - Highlights: • An existence of the short-range FM order in the La 0.7 Ca 0.3−x Ba x MnO 3 nanoparticles. • High magnetic entropy change, wide operative temperature range, and high RCP value. • Field dependences of |ΔS max | and RCP can be expressed by the power laws. • All the ΔS m (T, H) data are followed a universal master curve

Algae-based biodiesel is considered a promising alternative energy; therefore, the treatment of microalgae residues would be necessary. Anaerobic processes can be used for treating oil-extracted microalgae residues (OMR) and at the same time for recovering bioenergy. In this study, anaerobic batch experiments were conducted to evaluate the potential of recovering bioenergy, in the forms of butanol, H2, or CH4, from pretreated OMR. Using pretreated OMR as the only substrate, a butanol yield of 0.086 g/g-carbohydrate was obtained at carbohydrate of 40 g/L. With supplemented butyrate, a highest butanol yield of 0.192 g/g-carbohydrate was achieved at pretreated OMR containing 25 g/L of carbohydrate with 15 g/L of butyrate addition, attaining the highest energy yield of 3.92 kJ/g-OMR and energy generation rate of 0.65 kJ/g-OMR/d. CH4 production from pretreated OMR attained an energy yield of 8.83 kJ/g-OMR, but energy generation rate required further improvement. H2 production alone from pretreated OMR might not be attractive regarding energy yield, but it attained a superb energy generation rate of 0.68 kJ/g-OMR/d by combining H2 production from pretreated OMR and butanol production from pretreated OMR with supplementary butyrate from H2 fermentation supernatant. This study demonstrated an integrated system as an option for treating OMR and recovering bioenergy. Copyright © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Previous work has shown the Orion Bar to be an interface between ionized and molecular gas, viewed roughly edge-on, which is excited by the light from the Trapezium cluster. Much of the emission from any star-forming region will originate from such interfaces, so the Bar serves as a foundation test of any emission model. Here we combine X-ray, optical, infrared (IR), and radio data sets to derive emission spectra along the transition from H + to H 0 to H 2 regions. We then reproduce the spectra of these layers with a simulation that simultaneously accounts for the detailed microphysics of the gas, the grains, and molecules, especially H 2 and CO. The magnetic field, observed to be the dominant pressure in another region of the Orion Nebula, is treated as a free parameter, along with the density of cosmic rays. Our model successfully accounts for the optical, IR, and radio observations across the Bar by including a significant magnetic pressure and also heating by an excess density of cosmic rays, which we suggest is due to cosmic rays being trapped in the compressed magnetic field. In the Orion Bar, as we had previously found in M17, momentum carried by radiation and winds from the newly formed stars pushes back and compresses the surrounding gas. There is a rough balance between outward momentum in starlight and the total pressure in atomic and molecular gas surrounding the H + region. If the gas starts out with a weak magnetic field, the starlight from a newly formed cluster will push back the gas and compress the gas, magnetic field, and cosmic rays until magnetic pressure becomes an important factor.

We present a detailed study of the quasar-galaxy pair: J1243+4043-UGC 07904. The sight line of the background quasar ( zq = 1.5266) passes through a region of the galaxy (zg = 0.0169) at an impact parameter of 6.9 kpc with high metallicity (0.5 Z⊙) and negligible dust extinction. We detect H I 21-cm absorption from the foreground galaxy at arcsecond and milliarcsecond scales. For typical cold neutral medium (CNM) temperatures in the Milky Way, this 21-cm absorber can be classified as a damped Lyα absorber (DLA). We infer the harmonic mean spin temperature of the gas to be ˜400 K and for a simple two-phase medium we estimate the CNM fraction to be fCNM = 0.27. This is remarkably consistent with the CNM fraction observed in the Galaxy and less than that of high-redshift DLAs. The quasar exhibits a core-jet morphology on milliarcsecond scales, corresponding to an overall extent of ˜9 pc at zg. We show that the size of CNM absorbing clouds associated with the foreground galaxy is >5 pc and they may be part of cold gas structures that extend beyond ˜35 pc. Interestingly, the rotation measure of quasar J1243+4043 is higher than any other source in samples of quasars with high-z DLAs. However, we do not find any detectable differences in rotation measures and polarization fraction of sight lines with or without high-z (z ≥ 2) DLAs or low-z (z ≤ 0.3) 21-cm absorbers. Finally, the foreground galaxy UGC 07904 is also part of a galaxy group. We serendipitously detect H I 21-cm emission from four members of the group, and an ˜80 kpc long H I bridge connecting two of the other members. The latter, together with the properties of the group members, suggests that the group is a highly interactive environment.

Dynamics of the D(+) + H2 → HD + H(+) reaction at the low energy regime by means of a statistical quantum method.

The D(+) +H2(v = 0, j = 0, 1) → HD+H(+) reaction has been investigated at the low energy regime by means of a statistical quantum mechanical (SQM) method. Reaction probabilities and integral cross sections (ICSs) between a collisional energy of 10(-4) eV and 0.1 eV have been calculated and compared with previously reported results of a time independent quantum mechanical (TIQM) approach. The TIQM results exhibit a dense profile with numerous narrow resonances down to Ec ~ 10(-2) eV and for the case of H2(v = 0, j = 0) a prominent peak is found at ~2.5 × 10(-4) eV. The analysis at the state-to-state level reveals that this feature is originated in those processes which yield the formation of rotationally excited HD(v' = 0, j' > 0). The statistical predictions reproduce reasonably well the overall behaviour of the TIQM ICSs at the larger energy range (Ec ≥ 10(-3) eV). Thermal rate constants are in qualitative agreement for the whole range of temperatures investigated in this work, 10-100 K, although the SQM values remain above the TIQM results for both initial H2 rotational states, j = 0 and 1. The enlargement of the asymptotic region for the statistical approach is crucial for a proper description at low energies. In particular, we find that the SQM method leads to rate coefficients in terms of the energy in perfect agreement with previously reported measurements if the maximum distance at which the calculation is performed increases noticeably with respect to the value employed to reproduce the TIQM results.

The close-coupling hyperspherical (CCH) exact quantum method was used to study the title barrierless reaction up to a collision energy (E T ) of 0.75 eV, and the results compared with quasiclassical trajectory (QCT) calculations to determine the importance of quantum effects. The CCH integral cross section decreased with E T and, although the QCT results were in general quite similar to the CCH ones, they presented a significant deviation from the CCH data within the 0.2-0.6 eV collision energy range, where the QCT method did not correctly describe the reaction probability. A very good accord between both methods was obtained for the OH + vibrational distribution, where no inversion of population was found. For the OH + rotational distributions, the agreement between the CCH and QCT results was not as good as in the vibrational case, but it was satisfactory in many conditions. The kk ' angular distribution showed a preferential forward character, and the CCH method produced higher forward peaks than the QCT one. All the results were interpreted considering the potential energy surface and plots of a representative sampling of reactive trajectories
Investigation of the J/ψproduction via the decay J/ψ→μ+μ- at the ep storage ring HERA

The data taken with the H1-detector at the storage ring HERA in the year 1993 are analysed for events of the type ep →eJ/ψX; J/ψ→μ + μ - . In total 42±8 J/ψ→μ + μ - events are found. Only a few of these events (3±2) are produced via large momentum transfer (Q 2 >4 GeV 2 ). The main part is produced in the area of photoproduction with Q 2 2 (Q 2 ∼0). Half of the events (21±5) show no further activity inside the detector (acceptance region: 8 el (ep→eJ/ψX)=(9.5±2.5±2.5)nb is derived for this type of quasielastic J/ψ production in the region 30 GeV γp 2 2 this corresponds to a γp-cross-section of σ el (γp→J/ψX)=(60±15±15)nb at an average γp-CMS-energy of γP >∼90 GeV. The cross-section for the inelastic J/ψ-production is measured in the region 30 GeV γp ψ /E γ in the proton rest frame). In the region 0.5 in (ep→eJ/ψ/X)=(4.8±1.7±1.2)nb and σ in (γp→J/ψX)=(30± 11±7)nb respectively. The possibility to reconstruct the kinematics of inelastic events without detecting the scattered electron is demonstrated. Further results, e.g. the measurement of the gluon density distribution of the proton, can not be obtained due to the limited statistics. It is however shown, that with higher statistics very interesting results can be expected analysing the J/ψ production at HERA. (orig.)
Search for H-dibaryon at J-PARC with a Large Acceptance TPC

Sako H.

Full Text Available H-dibaryon has been predicted as a stable 6-quark color-singlet state. It has been searched for by many experiments but has never been discovered. Recent lattice QCD calculations predict H-dibaryon as a weakly bound or a resonant state close to the LL threshold. E224 and E522 experiments at KEK observed peaks in LL invariant mass spectra near the threshold in (K-, K+ reactions, which were statistically not significant. Therefore, we proposed a new experiment E42 at J-PARC. It will measure decay products of ΛΛ and Λπ-p in a (K-, K+ reaction. We design a large acceptance spectrometer based on a Time Projection Chamber (TPC immersed in a dipole magnetic field. The TPC surrounds a target to cover nearly 4π acceptance, and accepts K- beams up to 106 counts per second. To suppress drift field distortion at high beam rates, we adopt Gas Electron Multipliers (GEMs for electron amplification and a gating grid. We show an overview of the experiment, the design of the spectrometer, and the R&D status of the TPC prototype.

Proton nuclear magnetic resonance (NMR) spectra and spin-lattice relaxation rates for the solid solution α-MnH 0.06 have been measured over the temperature range 11-297 K and the resonance frequency range 20-90 MHz. A considerable shift and broadening of the proton NMR line and a sharp peak of the spin-lattice relaxation rate are observed near 130 K. These effects are attributed to the onset of antiferromagnetic ordering below the Néel temperature TN≈130 K. The proton NMR line does not disappear in the antiferromagnetic phase; this suggests a small magnitude of the local magnetic fields at H-sites in α-MnH 0.06. The spin-lattice relaxation rate in the paramagnetic phase is dominated by the effects of spin fluctuations.

The state-to-state dynamics of the H * (n) + HD → D * (n ′ ) + H 2 reactive scattering at the collision energy of 0.5 eV have been carried out for the first time by using H-atom Rydberg tagging time-of-flight technique. Experimental results show that the angular distribution of the total H 2 products presents clearly forward-backward asymmetric, which considerably differs from that of the corresponding H + + HD → D + + H 2 reaction predicted by previously theoretical calculations. Such disagreement between these two processes suggests that the Fermi independent-collider model is also not valid in describing the dynamics of isotopic variants of the H * + H 2 reaction. The rotational state distribution of the H 2 products demonstrates a saw-toothed distribution with odd-j ′ > even-j ′ . This interesting observation is strongly influenced by nuclear spin statistics

Highlights: • Ultrathin HSN Ns were first synthesized based on molten salt synthesis method. • HSN Ns Exhibit 5.5 times higher activity than that of the HSN Ps. • The enhanced photocatalytic activity of HSN Ns is due to the reduction in thickness. - Abstract: The SrBi{sub 2}Nb{sub 2}O{sub 9} platelets with a thickness of about 600 nm were synthesized by molten salt synthesis method. The treatment of the SrBi{sub 2}Nb{sub 2}O{sub 9} platelets with hydrochloric acid resulted in the formation of the protonated H{sub 1.78}Sr{sub 0.78}Bi{sub 0.22}Nb{sub 2}O{sub 7} platelets. Through a top–down approach in ethylamine solution, the H{sub 1.78}Sr{sub 0.78}Bi{sub 0.22}Nb{sub 2}O{sub 7} platelets were exfoliated into H{sub 1.78}Sr{sub 0.78}Bi{sub 0.22}Nb{sub 2}O{sub 7} nanosheets with a thickness of about 2.6 nm. The evolution of the structure, composition, morphology, optical, and photocatalytic properties of SrBi{sub 2}Nb{sub 2}O{sub 9} platelets was studied as it is converted into H{sub 1.78}Sr{sub 0.78}Bi{sub 0.22}Nb{sub 2}O{sub 7} platelets and subsequently exfoliated into H{sub 1.78}Sr{sub 0.78}Bi{sub 0.22}Nb{sub 2}O{sub 7} nanosheets. The absorption edge shifts to a lower wavelength accompanied by the protonation and exfoliation. The photocatalytic H{sub 2} evolution of the three samples were evaluated under the irradiation of a 300 W Xenon lamp from CH{sub 3}OH/H{sub 2}O solution, indicating that H{sub 1.78}Sr{sub 0.78}Bi{sub 0.22}Nb{sub 2}O{sub 7} nanosheets Exhibit 5.5 and 26.2 times higher activity than that of the H{sub 1.78}Sr{sub 0.78}Bi{sub 0.22}Nb{sub 2}O{sub 7} and SrBi{sub 2}Nb{sub 2}O{sub 9} platelets, respectively. The enhanced activity for the H{sub 1.78}Sr{sub 0.78}Bi{sub 0.22}Nb{sub 2}O{sub 7} nanosheets is mainly attributed to the higher separation efficiency of the photogenerated carriers and the larger specific surface area caused by the significant reduction in thickness.
Elastic and proton dissociative J/{psi} photoproduction at low W{sub {gamma}p} with the H1 detector at HERA

Huber, Florian

2013-02-15

Elastic and proton dissociative photoproduction of J/{psi} mesons is measured with the H1 detector at the HERA electron proton collider in the photon virtuality phase space of Q{sup 2}J/{psi} measurement with central tracks in an extended kinematic phase space in a photon proton centre of mass energy range of 20 GeVH1 analyses. Due to an online selection purely based on tracks both leptonic decay channels J/{psi}{yields}ee and J/{psi}{yields}{mu}{mu} are available for the analysis. Elastic ({gamma}p{yields} J/{psi}p) and proton dissociative ({gamma}p{yields} J/{psi}Y) differential {gamma}p cross sections are determined in a simultaneous measurement as function of the squared momentum transfer at the proton vertex t and as function of W{sub {gamma}p} by means of an unfolding procedure, taking not only all bin correlations into account, but also the correlation between the elastic and proton dissociative process. The obtained elastic and proton dissociative differential cross sections are analysed in a simultaneous fit, taking the full statistical covariance matrices and systematic uncertainty sources into account.

Decays of B(s)(0) and B(0) mesons into J/ψ π+π-π+π- final states, produced in pp collisions at the LHC, are investigated using data corresponding to an integrated luminosity of 3 fb-1 collected with the LHCb detector. B(s)(0) → J/ψ f1(1285) decays are seen for the first time, and the branching fractions are measured. Using these rates, the f1(1285) mixing angle between strange and nonstrange components of its wave function in the qq structure model is determined to be ±(24.0-2.6-0.8+3.1+0.6)°. Implications on the possible tetraquark nature of the f1(1285) are discussed.

Nano-silica supported titanium tetrachloride (TiCl4.SiO2) was prepared and used as an acid catalyst for the 14-aryl or alkyl-14H-dibenzo[a,,j]xanthenesreaction under solvent-free conditions. Compared to the classical 14-aryl or alkyl-14H-dibenzo[a,j]xanthenesreaction conditions, this method consistently has the advantage of excellent yields, mild reaction conditions, ease of workup, survival of different functional groups and short reaction times.

Time-dependent CP violation is measured in the $B^0\\rightarrow J/\\psi\\pi^+\\pi^-$ channel for each $\\pi^+\\pi^-$ resonant final state using data collected with an integrated luminosity of 3.0 fb$^{-1}$ in $pp$ collisions using the LHCb detector. The final state with the largest rate, $J/\\psi\\rho^0(770)$, is used to measure the CP-violating angle $2\\beta^{\\rm eff}$ to be $(41.7\\pm 9.6_{-6.3}^{+2.8})^{\\circ}$. This result can be used to limit the size of penguin amplitude contributions to CP violation measurements in, for example, $B_s^0\\rightarrow J/\\psi\\phi$ decays. Assuming approximate SU(3) flavour symmetry and neglecting higher order diagrams, the shift in the CP-violating phase $\\phi_s$ is limited to be within the interval [$-1.05^\\circ$, +$1.18^\\circ$] at 95% confidence level. Changes to the limit due to SU(3) symmetry breaking effects are also discussed.

$\\sin(2\\beta)$ with $B^0 \\rightarrow\\!J/\\!\\psi K_\\text{S}$ at the LHCb experiment

CERN Multimedia

Niet, Ramon

2015-01-01

The poster presents the recent measurement of $\\sin(2\\beta)$ using $B^0$ decays to the $J/\\!\\psi K_\\text{S}$ final state. The measurement is based on a dataset corresponding to an integrated luminosity of 3.0$\\,\\text{fb}^{-1}$ collected with the LHCb experiment in proton-proton collisions at center-of-mass energies of 7 and 8 TeV. To control penguin pollutions in the determination of $\\sin(2\\beta)$, $B_s^0$ decays to the same final state can be analysed. The results of the corresponding analysis are presented as well.
Discovery of the hard spectrum VHE γ-ray source HESS J1641-463

International Nuclear Information System (INIS)

Abramowski, A.; Ait Benkhali, F.

2014-10-01

This letter reports the discovery of a remarkably hard spectrum source, HESS J1641.463, by the High Energy Stereoscopic System (H.E.S.S.) in the very high energy (VHE) domain. HESS J1641.463 remained unnoticed by the usual analysis techniques due to confusion with the bright nearby source HESS J1640.465. It emerged at a significance level of 8.5 standard deviations after restricting the analysis to events with energies above 4 TeV. It shows a moderate flux level of φ (E>1 TeV)=(3.64 ± 0.44 stat ± 0.73 sys ) x 10 -13 cm -2 s -1 , corresponding to 1.8% of the Crab Nebula flux above the same energy, and a hard spectrum with a photon index of Γ=2.07±0.11 stat ±0.20 sys . It is a point-like source, although an extension up to a Gaussian width of σ=3 arcmin cannot be discounted due to uncertainties in the H.E.S.S. point-spread function. The VHE γ-ray flux of HESS J1641.463 is found to be constant over the observed period when checking time binnings from the year-by-year to the 28 minute exposure timescales. HESS J1641.463 is positionally coincident with the radio supernova remnant SNR G338.5+0.1. No X-ray candidate stands out as a clear association; however, Chandra and XMM-Newton data reveal some potential weak counterparts. Various VHE γ-ray production scenarios are discussed. If the emission from HESS J1641.463 is produced by cosmic ray protons colliding with the ambient gas, then their spectrum must extend close to 1 PeV. This object may represent a source population contributing significantly to the galactic cosmic ray flux around the knee.
Investigation of magnetocaloric effect in La{sub 0.45}Pr{sub 0.25}Ca{sub 0.3}MnO{sub 3} by magnetic, differential scanning calorimetry and thermal analysis

We investigated magnetocaloric effect in La{sub 0.45}Pr{sub 0.25}Ca{sub 0.3}MnO{sub 3} by direct methods (changes in temperature and latent heat) and indirect method (magnetization isotherms). This compound undergoes a first-order paramagnetic to ferromagnetic transition with T{sub C}=200 K upon cooling. The paramagnetic phase becomes unstable and it transforms into a ferromagnetic phase under the application of magnetic field, which results in a field-induced metamagnetic transition (FIMMT). The FIMMT is accompanied by release of latent heat and temperature of the sample as evidenced from differential scanning calorimetry and thermal analysis experiments. A large magnetic entropy change of {Delta}S{sub m}=-7.2 J kg{sup -1} K{sup -1} at T=212.5 K and refrigeration capacity of 228 J kg{sup -1} are found for a field change of {Delta}H=5 T. It is suggested that destruction of magnetic polarons and growth of ferromagnetic phase accompanied by a lattice volume change with increasing magnetic field is responsible for the large magnetocaloric effect in this compound. - Highlights: Black-Right-Pointing-Pointer We report magnetic entropy change measured by indirect and direct methods in La{sub 0.45}Pr{sub 0.25}Ca{sub 0.3}MnO{sub 3.} Black-Right-Pointing-Pointer Anomalous field-induced induced metamagnetic transition is found in the paramagnetic state.

IGR J17464-3213, already known as the HEAO 1 transient source H1743-322, has been detected during a state transition by INTEGRAL SPI. We describe the spectral evolution and flaring activity of IGR J17464-3213/H1743-322 from 2003 March 21 to 2003 April 22. During the first part, the source followed a continuous spectral softening, with the peak of the spectral energy distribution shifting from 100 keV down to ~a few keV. However, the thermal disk and the hard X-ray components had a similar intensity, indicating that the source was in an intermediate state throughout our observations and evolving toward the soft state. In the second part of our observations, the RXTE ASM and INTEGRAL SPI light curves showed a strong flaring activity. Two flare events lasting about 1 day each have been detected with SPI and are probably due to instabilities in the accretion disk associated with the state transition. During these flares, the low (1.5-12 keV) and high (20-200 keV) energy fluxes monitored with the RXTE ASM and INTEGRAL SPI are correlated, and the spectral shape (above 20 keV) remains unchanged while the luminosity increases by a factor greater than 2.

A newly discovered autosomal recessive mutation, generalized lymphoproliferative disease (gld), in the C3H/HeJ strain of mice, determines the development of early onset massive lymphoid hyperplasia with autoimmunity. Significant lymph node enlargement is apparent as early as 12 wk of age. By 20 wk, lymph nodes are 50-fold heavier than those of coisogenic C3H/HeJ-+/+ mice. There is a concomitant increase in the numbers of peripheral blood lymphocytes. Analysis of C3H-gld lymph node lymphocyte subsets by immunofluorescence indicates an increase in numbers of B cells, T cells, and null (Thy-1-, sIg-) lymphocytes by 6-, 15-, and 33-fold compared with congeneic control mice. Serologically, gld/gld mice develop antinuclear antibodies (including anti-dsDNA), thymocyte-binding autoantibody, and hypergammaglobulinemia with major increases in several immunoglobulin isotypes. Mutant gld mice live only one-half as long as normal controls (12 and 23 mo, respectively). Interstitial pneumonitis was found in virtually all C3H-gld mice autopsied when moribund. Although immune complexes were detected in the glomerulus by immunofluorescence techniques, only 14% of the autopsied mice had significant lupus-like nephritis. Vascular disease was not found. The pattern of early onset massive lymph node enlargement, hypergammaglobulinemia, and production of antinuclear autoantibodies resembles the basic abnormal phenotype induced by the lpr (lymphoproliferation) mutation. The mutations gld and lpr are not allelic. Linkage studies indicate that gld is located between Pep-3 and Lp on chromosome 1. This new mutation adds another genetically well-defined model to the list of murine lymphoproliferative/autoimmune disorders that may be exploited to gain a clearer understanding of immunoregulatory defects and for identifying common pathogenetic factors involved in systemic autoimmune diseases.

In this work, we report the effect of Na doping on the structural, magnetic and magnetocaloric properties in La{sub 0.8}Ca{sub 0.2−x}Na{sub x}MnO{sub 3} powder samples. Our polycristalline samples have been synthesized using the solid-state reaction method at high temperatures. The parent compound La{sub 0.8}Ca{sub 0.2}MnO{sub 3} crystallizes in the orthorhombic system with Pbnm space group. Na doping induces a structural transition from orthorhombic (Pbnm space group) to rhombohedral (R-3C space group) symmetry. Magnetization measurements versus temperature in a magnetic applied field of 50 mT showed that all our investigated samples display a paramagnetic-ferromagnetic transition with decreasing temperature. The Curie temperature T{sub C} increases with Na content from 240 K for x=0 to 330 K for x=0.2. A large magnetocaloric effect has been observed in all samples, the maximum entropy change, |∆S{sub M}|{sub max}, shifts to smaller values with increasing Na content, from4.56 J/kg K (x=0.05) to 2.3 J/kg K (x=0.2) under a magnetic field change ∆µ{sub 0}H of 2 T. For the same applied magnetic field of 2 T, the Relative Cooling Power (RCP) values are found to be constant around 91 J/kg. - Graphical abstract: Sodium doping induces an increase of T{sub C} from 240 K for x=0 to 330 K for x=0.2. - Highlights: • La{sub 0.8}Ca{sub 0.2−x}Na{sub x}MnO{sub 3} are synthesized using the ceramic method at high temperatures. • Na doping induces a structural transition from Pbnm to R-3C space group. • T{sub C} increases with Na content from 240 K for x=0 to 330 K for x=0.2. • RCP is constant around 91 J/kg for all compounds under 2 T.

When triaging a patient with acute chest pain at first medical contact, an electrocardiogram (ECG) is routinely made and inspected for signs of myocardial ischemia. The guidelines recommend comparison of the acute and an earlier-made ECG, when available. No concrete recommendations for this comparison exist, neither is known how to handle J-point identification difficulties. Here we present a J-point independent method for such a comparison. After conversion to vectorcardiograms, baseline and acute ischemic ECGs after 3minutes of balloon occlusion during elective PCI were compared in 81 patients of the STAFF III ECG database. Baseline vectorcardiograms were subtracted from ischemic vectorcardiograms using either the QRS onsets or the J points as synchronization instants, yielding vector magnitude difference signals, ΔH. Output variables for the J-point synchronized differences were ΔH at the actual J point and at 20, 40, 60 and 80ms thereafter. Output variables for the onset-QRS synchronized differences were the ΔH at 80, 100, 120, 140 and 160ms after onset QRS. Finally, linear regressions of all combinations of ΔHJ+… versus ΔHQRS+… were made, and the best combination was identified. The highest correlation, 0.93 (pJ point and 160ms after the onset of the QRS complex. With a ΔH ischemia threshold of 0.05mV, 66/81 (J-point synchronized differences) and 68/81 (onset-QRS synchronized differences) subjects were above the ischemia threshold, corresponding to sensitivities of 81% and 84%, respectively. Our current study opens an alternative way to detect cardiac ischemia without the need for human expertise for determination of the J point by measuring the difference vector magnitude at 160ms after the onset of the QRS complex.

Partial conductivities are presented for BaZr0.7Ce0.2Y0.1O3-δ, an important proton conductor for protonic-ceramic fuel cells and membrane reactors. Atmospheric dependencies of impedance performed in humidified and dry O2, air, N2 and H2(10%)/N2(90%) in the temperature range 300-900 °C, supported by the modified emf method, confirm significant electron-hole and protonic contributions to transport. For very reducing and wet atmospheres, the conductivity is predominantly ionic, with a higher participation of protons with decreasing temperature and increasing water-vapour partial pressure (pH2O). From moderately reducing conditions of wet N2 to wet O2, however, the conductivity is considerably influenced by electron holes as revealed by a significant dependence of total conductivity on oxygen partial pressure (pO2). With higher pH2O, proton transport increases, with a concomitant decrease of holes and oxygen vacancies. However, the effect of pH2O is also influenced by temperature, with a greater protonic contribution at both lower temperature and pO2. Values of proton transport number tH ≈ 0.63 and electronic transport number th ≈ 0.37 are obtained at 600 °C for pH2O = 0.022 atm and pO2 = 0.2 atm, whereas tH ≈ 0.95 and th ≈ 0.05 for pO2 = 10-5 atm. A hydration enthalpy of -109 kJ mol-1 is obtained in the range 600-900 °C.

Upper limits on the cross-section of the pair-production process e+e- -> h0A0 assuming 100% decays into hadrons, are derived from a new search for the h0A0 -> hadrons topology, independent of the hadronic flavour of the decay products. Searches for the neutral Higgs bosons h0 and A0, are used to obtain constraints on the Type II Two Higgs Doublet Model (2HDM(11)) with no CP violation in the Higgs sector and no additional non Standard Model particles besides the five Higgs bosons. The analysis combines LEP1 and LEP2 data collected with the OPAL detctor up to the highest available centre-of-mass energies. The searches are sensitive to the h0, A0 -> qq, gg,tau+tau- and h0 -> A0A0 decay modes of the Higgs bosons. The 2HDM(II) parameter space is explored in a detailed scan. Large regions of the 2HDM(II) parameter space are excluded at the 95% CL in the (mh, mA), (mh, tanb) and (mA, tanb) planes, using both direct neutral Higgs boson searches and indirect limits derived from Standard Model high precision measuremen...

The magnetocaloric effect along with magnetic phase transition in the peroveskite polycrystalline samples La0.7Ba0.2Ca0.1Mn1-xSnxO3 (x = 0 and 0.1) was investigated. The samples were synthesized using conventional solid state reaction at 1400 °C temperature. Magnetization vs. temperature measurements, under a magnetic field of μ0H = 0.05 T, showed a paramagnetic-ferromagnetic transition at Curie temperature, TC, which decreases from 310 K for x = 0-290 K for x = 0.1. A large magnetic entropy change | ΔSM | deduced from isothermal magnetization curves, has been observed in our samples with a peak centered on their respective TC. Interesting values of the relative cooling power (RCP), 237 J kg-1 for x = 0 and 248 J kg-1 x = 0.1, make these samples promising candidates for magnetic refrigeration around room temperature.

In an effort to thermodynamically stabilize the alane (i.e., to increase the desorption enthalpy), partial substitution of Mg for Al was investigated by ball milling the mixtures (1 - x)AlH 3 /xMgH 2 (x = 0.1, 0.2 and 0.3). Rietveld analysis of the XRD profiles showed that the cell volume of α-AlH 3 increased with the Mg substitution rate, and thereby formation of solid solutions was assumed (x ≤ 0.05). In agreement with the experimental results, theoretical calculations indicated that a hypothetical supercell structure (MgAl 15 )H 47 (x = 0.0625), which contained a hydrogen vacancy, was at least metastable. However, the effect of alane stabilization by Mg substitution for Al was not observed, either by experiment or by simulation, and only an increase in the activation energy was measured.

Using stimulated Raman adiabatic passage (SARP), it is possible, in principle, to transfer all the population in a rovibrational level of an isolated diatomic molecule to an excited rovibrational level. We use an overlapping sequence of pump (532 nm) and dump (683 nm) single-mode laser pulses of unequal fluence to prepare isolated H2 molecules in a molecular beam. In a first series of experiments we were able to transfer more than half the population to an excited rovibrational level [N. Mukherjee, W. R. Dong, J. A. Harrison, and R. N. Zare, J. Chem. Phys. 138(5), 051101-1051101-4 (2013)], 10.1063/1.4790402. Since then, we have achieved almost complete transfer (97% ± 7%) of population from the H2 (v = 0, J = 0) ground rovibrational level to the H2 (v = 1, J = 0) excited rovibrational level. An explanation is presented of the SARP process and how these results are obtained.

Constraining the dark energy models with H (z ) data: An approach independent of H0

We study the performance of the latest H (z ) data in constraining the cosmological parameters of different cosmological models, including that of Chevalier-Polarski-Linder w0w1 parametrization. First, we introduce a statistical procedure in which the chi-square estimator is not affected by the value of the Hubble constant. As a result, we find that the H (z ) data do not rule out the possibility of either nonflat models or dynamical dark energy cosmological models. However, we verify that the time varying equation-of-state parameter w (z ) is not constrained by the current expansion data. Combining the H (z ) and the Type Ia supernova data, we find that the H (z )/SNIa overall statistical analysis provides a substantial improvement of the cosmological constraints with respect to those of the H (z ) analysis. Moreover, the w0-w1 parameter space provided by the H (z )/SNIa joint analysis is in very good agreement with that of Planck 2015, which confirms that the present analysis with the H (z ) and supernova type Ia (SNIa) probes correctly reveals the expansion of the Universe as found by the team of Planck. Finally, we generate sets of Monte Carlo realizations in order to quantify the ability of the H (z ) data to provide strong constraints on the dark energy model parameters. The Monte Carlo approach shows significant improvement of the constraints, when increasing the sample to 100 H (z ) measurements. Such a goal can be achieved in the future, especially in the light of the next generation of surveys.
Temperature dependence of the minimum in AC power losses of (Nb/sub 0.99/Zr/sub 0.01/)3Sn in parallel AC and DC magnetic fields

1980-01-01

ac losses P/sub L/ of bronze-processed (Nb/sub 0.99/Zr/sub 0.01/) 3 Sn strips have been measured between 4.2 and 16.5 K in the presence of a dc magnetic field H 0 . The measurements were performed using an electronic wattmeter with both ac and dc fields parallel to the long flat surfaces of the sample. A minimum in the function P/sub L/(H 0 ) was observed for fixed ac amplitudes h 0 . This minimum was found to occur in the entire temperature range between 4.2 and 16.5 K. A similar minimum was recently reported in Nb 3 Ge [Thompson et al., J. Appl. Phys. 50, 3514 (1979)] at 4.2 K. The position of the minimum is explained here by the same physical model as in Thompson et al. [J. Appl. Phys. 50, 3514 (1979)]; and Clem (ibid. 3518), but extending the model to include the temperature dependence of the entry surface shielding fields ΔH/sub en/(B,T) for flux density in the sample B=0. It is also shown here that loss minimum measurements can be used for the determination of ΔH/sub en/(0,T) in the temperature range 4.2--16.5 K

High-temperature H2O/CO2 co-electrolysis through reversible solid oxide electrolysis cell (SOEC) provides potentially a feasible and eco-friendly way to convert electrical energy into chemicals stored in syngas. In this work, La0.8Sr0.2Co0.8Ni0.2O3-δ (LSCN) impregnated Gd0.1Ce0.9O1.95 (GDC)-(La0.8Sr0.2)0.95MnO3-δ (LSM) composite oxygen electrode is studied as high-performance electrode for H2O/CO2 co-electrolysis. The LSCN impregnated cell exhibits competitive performance with the peak power density of 1057 mW cm-2 at 800 °C in solid oxide fuel cell (SOFC) mode; in co-electrolysis mode, the current density can reach 1.60 A cm-2 at 1.5 V at 800 °C with H2O/CO2 ratio of 2/1. With LSCN nanoparticles dispersed on the surface of GDC-LSM to maximize the reaction active sites, the LSCN impregnated cell shows significant enhanced electrochemical performance at both SOEC and SOFC modes. The influence of feed gas composition (H2O-H2-CO2) and operating voltages on the performance of co-electrolysis are discussed in detail. The cell shows a very stable performance without obvious degradation for more than 100 h. Post-test characterization is analyzed in detail by multiple measurements.
Laser spectroscopic studies of the pure rotational U0(0) and W0(0) transitions of solid parahydrogen

International Nuclear Information System (INIS)

Chan, M.; Lee, S.S.; Okumura, M.; Oka, T.

1991-01-01

High resolution spectrum of multipole-induced transitions of solid parahydrogen was recorded using diode and difference frequency laser spectroscopy. The J=4 left-arrow 0 pure rotational U 0 (0) transition observed in the diode spectrum agrees well in frequency with the value reported by Balasubramanian et al. [Phys. Rev. Lett. 47, 1277 (1981)] but we observed a spectral width smaller by about a factor of 4. The J=6 left-arrow 0 W 0 (0) transition was observed to be exceedingly sharp, with a width of ∼70 MHz, using a difference frequency spectrometer with tone-burst modulation. This transition is composed of three components with varying relative intensity depending upon the direction of polarization of laser radiation. These components were interpreted as the splitting of the M levels in the J=6 state due to crystal field interactions. In addition, a new broad feature was found at 2452.4 cm -1 in the low resolution Fourier-transform infrared (FTIR) spectrum of solid hydrogen and was assigned to be the phonon branch W R (0) transition of the W 0 (0) line. The selection rules, crystal field splitting of J=4 and J=6 rotons, and the measured linewidth based on these observations are discussed

Given the bone tropism of prostate cancer, conventional imaging modalities poorly identify or quantify metastatic disease. 89 Zr-huJ591 positron emission tomography (PET) imaging was performed in patients with metastatic prostate cancer to analyze and validate this as an imaging biomarker for metastatic disease. The purpose of this initial study was to assess safety, biodistribution, normal organ dosimetry, and optimal imaging time post-injection for lesion detection. Ten patients with metastatic prostate cancer received 5 mCi of 89 Zr-huJ591. Four whole-body scans with multiple whole-body count rate measurements and serum activity concentration measurements were obtained in all patients. Biodistribution, clearance, and lesion uptake by 89 Zr-huJ591 immuno-PET imaging was analyzed and dosimetry was estimated using MIRD techniques. Initial assessment of lesion targeting of 89 Zr-huJ591 was done. Optimal time for imaging post-injection was determined. The dose was well tolerated with mild chills and rigors seen in two patients. The clearance of 89 Zr-huJ591 from serum was bi-exponential with biological half-lives of 7 ± 4.5 h (range 1.1-14 h) and 62 ± 13 h (range 51-89 h) for initial rapid and later slow phase. Whole-body biological clearance was 219 ± 48 h (range 153-317 h). The mean whole-body and liver residence time was 78.7 and 25.6 h, respectively. Dosimetric estimates to critical organs included liver 7.7 ± 1.5 cGy/mCi, renal cortex 3.5 ± 0.4 cGy/mCi, and bone marrow 1.2 ± 0.2 cGy/mCi. Optimal time for patient imaging after injection was 7 ± 1 days. Lesion targeting of bone or soft tissue was seen in all patients. Biopsies were performed in 8 patients for a total 12 lesions, all of which were histologically confirmed as metastatic prostate cancer. One biopsy-proven lesion was not positive on 89 Zr-huJ591, while the remaining 11 lesions were 89 Zr-huJ591 positive. Two biopsy-positive nodal lesions were noted only on 89 Zr-huJ591 study, while the

This LHCb Thesis consists of three main parts. First, characterisation studies of Medipix3 silicon detectors using charged-particle beams in the context of the VELO upgrade: average cluster size and resolution versus threshold have been found to not change significantly between irradiated and non-irradiated assemblies, proving that Medipix3 assemblies are hard-radiation suitable for the development of Timepix3 and Velopix assemblies. Second, measurement of penguin pollution to the $CP$-violating $\\phi_s$ phase using $B_s^0{\\to}J/\\psi{\\phi}$ decays: polarisation fractions and direct CP violation have been found to be in agreement with SM predictions, while penguin pollution have been found to be small and under control. Third, a search of $A_1^0{\\to}\\mu^+\\mu^-$ decays where $A_1^0$ is the light $CP$-odd Higgs boson in the NMSSM: the analysis is not finished yet, however, it is in good shape and a sensible improvement with respect to previous estimations is expected - updates can be found in the LHCb analysis ...
How to employ {\\overline{B}}_d^0\\to J/ψ (π η, \\overline{K}K) decays to extract information on π η scattering

We demonstrate that dispersion theory allows one to deduce crucial information on π η scattering from the final-state interactions of the light mesons visible in the spectral distributions of the decays {\\overline{B}}_d^0\\to J/ψ ({π}^0η, {K}+{K}-,{K}^0{\\overline{K}}^0) . Thus high-quality measurements of these differential observables are highly desired. The corresponding rates are predicted to be of the same order of magnitude as those for {\\overline{B}}_d^0\\to J/ψ {π}+{π}- measured recently at LHCb, letting the corresponding measurement appear feasible.

We observed this unique relativistic binary with the Chandra Advanced CCD Imaging Spectrometer detector for 31.6 ks. Surprisingly, not a single photon was detected within the 3'' radius from the J1906+0746 radio position. For a plausible range of hydrogen column densities, n H = (0.5-1) x 10 22 cm -2 , the nondetection corresponds to the 90% upper limit of (3-5) x 10 30 erg s -1 on the unabsorbed 0.5-8 keV luminosity for the power-law model with Γ = 1.0-2.0, and ∼10 32 erg s -1 on the bolometric luminosity of the thermal emission from the neutrons star surface. The inferred limits are the lowest known for pulsars with spin-down properties similar to those of PSR J1906+0746. We have also tentatively detected a puzzling extended structure which looks like a tilted ring with a radius of 1.'6 centered on the pulsar. The measured 0.5-8 keV flux of the feature, ∼3.1 x 10 -14 erg cm -2 s -1 , implies an unabsorbed luminosity of 1.2 x 10 32 erg s -1 (4.5 x 10 -4 of the pulsar's E-dot) for n H = 0.7 x 10 22 cm -2 . If the ring is not a peculiar noise artifact, the pulsar wind nebula around an unusually underluminous pulsar would be the most plausible interpretation.
Emittance measurements for optimum operation of the J-PARC RF-driven H{sup −} ion source

In order to satisfy the Japan Proton Accelerator Research Complex (J-PARC) second stage requirements of an H{sup −} ion beam of 60mA within normalized emittances of 1.5πmm•mrad both horizontally and vertically, a flat top beam duty factor of 1.25% (500μs×25Hz) and a life-time of longer than 1month, the J-PARC cesiated RF-driven H{sup −} ion source was developed by using an internal-antenna developed at the Spallation Neutron Source (SNS). The transverse emittances of the source were measured with various conditions to find out the optimum operation conditions minimizing the horizontal and vertical rms normalized emittances. The transverse emittances were most effectively reduced by operating the source with the plasma electrode temperature lower than 70°C. The optimum value of the cesium (Cs) density around the beam hole of the plasma electrode seems to be proportional to the plasma electrode temperature. The fine control of the Cs density is indispensable, since the emittances seem to increase proportionally to the excessiveness of the Cs density. Furthermore, the source should be operated with the Cs density beyond a threshold value, since the plasma meniscus shape and the ellipse parameters of the transverse emittances seem to be changed step-function-likely on the threshold Cs value.

The polarization of the neonlike germanium J = 0 - 1 laser line, which would arise from the existence of a directed beam of hot electrons in the amplifying plasma, is theoretically investigated. The relative populations of the magnetic sublevels in the lower J = 1 laser level have been determined by allowing for the processes of direct excitation from the 2p 6 ground level and collisional de-excitation from the upper J = 0 laser level. Elastic collisions leading to transitions between the M J = 0 and M J =1 sublevels within the lower level of the lasing line have also been taken into account. The required elastic and inelastic collision strengths for transitions between magnetic sublevels have been computed in a semi-relativistic distorted-wave approximation, for incident electron energies up to 15 keV. Our calculations predict a rather low degree of polarization for the J = 0 - 1 line, although the elastic collisions are found to play a negligibly small role in the redistribution of magnetic sublevel populations.

The optical vibrations of hydrogen in TbNiAlH 1.4 and UNiAlH 2.0 were investigated by means of inelastic neutron scattering. The experimental data were analysed, including multiphonon neutron scattering contributions, calculated in an isotropic harmonic approximation. At least two fundamental H optical peaks were observed in TbNiAlH 1.4 , and were assigned to the vibrational modes of hydrogen atoms occupying different interstitial sites in the metal sublattice. The high-energy part of the UNiAlH 2.0 spectra is characterized by strong anharmonicity, and a broad fundamental band. The latter can be accounted for by a large dispersion of phonon modes due to the strong H-H interactions, and/or different metal-hydrogen force constants, which may originate from different metal atoms surrounding the H atoms in the unit cell
Further study of CP violation and branching ratios for B-bar0 → J/ψKs and B-bar0 → φKs in the standard model and beyond

In this work we study the CP violation for B-bar 0 → J/ψK s and B-bar 0 → φK s up to leading and next-to-leading order QCD corrections in the standard model, two-Higgs-doublet model and the minimal supersymmetric extension of the standard model. We also study the effect of new physics on the branching ratios of these two decay modes. We find that within the parameter space constrained by the observation of the decay b→sγ, new physics does not affect the CP asymmetries greatly, and the prediction of new physics to the branching ratios of B-bar 0 → J/ψK s and B-bar 0 → φK s is the same as that of the standard model up to a minor discrepancy as far as the Yukama coupling constants are perturbative.

The differential branching fraction of the rare decay $\\Lambda^{0}_{b} \\rightarrow \\Lambda^0 \\mu^+\\mu^-$ is measured as a function of $q^{2}$, the square of the dimuon invariant mass. The analysis is performed using proton-proton collision data, corresponding to an integrated luminosity of $3.0 \\mbox{ fb}^{-1}$, collected by the LHCb experiment. Evidence of signal is observed in the $q^2$ region below the square of the $J/\\psi$ mass. Integrating over $15 < q^{2} < 20 \\mbox{ GeV}^2/c^4$ the branching fraction is measured as $d\\mathcal{B}(\\Lambda^{0}_{b} \\rightarrow \\Lambda^0 \\mu^+\\mu^-)/dq^2 = (1.18 ^{+ 0.09} _{-0.08} \\pm 0.03 \\pm 0.27) \\times 10^{-7} ( \\mbox{GeV}^{2}/c^{4})^{-1}$, where the uncertainties are statistical, systematic and due to the normalisation mode, $\\Lambda^{0}_{b} \\rightarrow J/\\psi \\Lambda^0$, respectively. In the $q^2$ intervals where the signal is observed, angular distributions are studied and the forward-backward asymmetries in the dimuon ($A^{l}_{\\rm FB}$) and hadron ($A^{h}_{\\r...

Huber, Florian

2010-05-01

In this diploma thesis the elastic J/ψ vector meson photoproduction (ep→eJ/ψp) is studied in the decay channel J/ψ→e + e - with the H1 detector at the electron proton collider HERA. The data from the runs of the year 2007 with an integrated luminosity of 62.4 pb -1 are used. In this time HERA operated with tree different proton energies E p called high (920 GeV), medium (575 GeV) and low (460 GeV) with integrated luminosities 45.5 (high), 5.96 (medium) and 10.9 pb -1 (low). The kinematical region of vertical stroke t vertical stroke 2 , where t is the four momentum transfer at the proton vertex, and Q e 2 γp , is restricted to 40 GeV γp γp γp -b 0 vertical stroke t vertical stroke , which yields to b 0 =4.4±0.2(stat.). The cross section as a function of W γp is fitted by a power law, dσ/dW γp ∝W δ γp , and gives δ=0.66±0.07(stat.). (orig.)
Detection of CO (J=1-0) in the dwarf elliptical galaxy NGC 185

Wiklind, Tommy; Rydbeck, Gustaf

1987-01-01

The detection of CO (J = 1-0) emission in the dwarf elliptical galaxy NGC 185 is reported. The presence of massive molecular clouds in this early-type galaxy supports the idea of recent or ongoing stellar formation indicated by the population of blue stars in the center. The CO was detected in two positions in the galaxy, the center, and a prominent dustcloud. The emission profile has two peaks, roughly centered around the systemic velocity. It is found that NGC 185 is overluminous in blue light for its CO luminosity compared with Sc galaxies. This might indicate a higher star-formation efficiency for NGC 185 than for the late-type galaxies.
THE J = 1-0 TRANSITIONS OF 12CH+, 13CH+, AND 12CD+

International Nuclear Information System (INIS)

Amano, T.

2010-01-01

A new set of laboratory experimental frequencies for the J = 1-0 rotational transition of 12 CH + , 13 CH + , and 12 CD + are obtained by using a liquid nitrogen cooled extended negative glow discharge in a gas mixture of CH 4 and He. These frequencies are found to be significantly different from those reported previously. The unexpectedly large Zeeman effect and the spin-rotation hyperfine interaction for a 1 Σ molecule are observed. The Zeeman effect and the hyperfine interaction appear to be distinctively different for each isotopic species. Theoretical considerations reveal the isotopic dependence of the magnitudes of these effects, and they also provide strong evidence for the identifications.

Full Text Available The reaction between NaAsO2 and oxalic acid was studied by pH-metric and conductometric measurements, applying the methods of continual variation and pH-metric and conductometric titration. It was found that oxalic acid forms a complex anion of the type [AsOC2O4]-. The relative stability constant of the complex at ionic strengths, I, of 0.10 (log Kr = 4.70, 0.20 (log Kr = 4.51, 0.50 (log Kr = 4.24 and 0 (log K0r = 5.05 and thermodynamic para¬meters were calculated using the data obtained by pH-metric measurements at 25.0±0.1 °C (DH = 10.5 kJ mol-1, DG = –29.0 kJ mol-1, DS = 133 J mol-1 K-1.

Protein folding in the cell is usually aided by molecular chaperones, from which the Hsp70 (Hsp = heat shock protein) family has many important roles, such as aiding nascent folding and participating in translocation. Hsp70 has ATPase activity which is stimulated by binding to the J-domain present in co-chaperones from the Hsp40 family. Hsp40s have many functions, as for instance the binding to partially folded proteins to be delivered to Hsp70. However, the presence of the J-domain characterizes Hsp40s or, by this reason, as J-proteins. The J-domain alone can stimulate Hsp70 ATPase activity. Apparently, it also maintains the same conformation as in the whole protein although structural information on full J-proteins is still missing. This work reports the 1 H, 15 N and 13 C resonance assignments of the J-domain of a Hsp40 from Saccharomyces cerevisiae, named Sis1. Secondary structure and order parameter prediction from chemical shifts are also reported. Altogether, the data show that Sis1 J-domain is highly structured and predominantly formed by α-helices, results that are in very good agreement with those previously reported for the crystallographic structure.
Rotational state modification and fast ortho-para conversion of H2 trapped within the highly anisotropic potential of Pd(210)

The rotational state and ortho-para conversion of H2 on a Pd(210) surface is investigated with rotational-state-selective temperature-programmed desorption (RS-TPD) and theoretical calculations. The isotope dependence of TPD shows a higher desorption energy for D2 than that for H2, which is ascribed to the rotational and zero-point vibrational energies. The RS-TPD data show that the desorption energy of H2(J =1 ) (J : rotational quantum number) is higher than that of H2(J =0 ). This is due to the orientationally anisotropic potential confining the adsorbed H2, which is in agreement with theoretical calculations. Furthermore, the H2 desorption intensity ratio in J =1 and J =0 indicates fast ortho-para conversion in the adsorption state, which we estimate to be of the order of 1 s.

We present a phase-coherent timing solution for RX J0420.0-5022, the coolest (kT ≅ 45 eV) and fastest-spinning (P = 3.45 s) of the seven so-called isolated neutron stars (INSs). Using 14 observations with the XMM-Newton spacecraft in 2010 and 2011, we were able to measure a spin-down rate ν-dot = (-2.3 ± 0.2) x 10 15 Hz s -1 (P-dot =(2.8±0.3)x10 -14 s s -1 ), from which we infer a dipolar magnetic field of 1.0 x 10 13 G. With reasonable confidence we were able to extend the timing solution back to archival XMM-Newton from 2002 and 2003, giving the same solution but with considerably more precision. This gives RX J0420.0-5022 the lowest dipole magnetic field of the INSs. Our spectroscopy does not confirm the broad absorption feature at 0.3 keV hinted at in earlier observations, although difficulties in background subtraction near that energy make conclusions difficult. With this, all six of the INSs that have confirmed periodicities now have constrained spin-downs from coherent solutions. The evidence that the INSs are qualitatively different from rotation-powered pulsars now appears robust, with the likely conclusion that their characteristic ages are systematically older than their true ages, because their fields have decayed. The field decay probably also causes them to be systematically hotter than pulsars of the same (true) age.

The comparative studies on grading in subarachnoid hemorrhage (SAH) had several limitations such as the unclear grading of Glasgow Coma Scale 15 with neurological deficits in World Federation of Neurosurgical Societies (WFNS), and the inclusion of systemic disease in Hunt and Hess (H&H) scales. Their differential incremental impacts and optimum cut-off values for unfavourable outcome are unsettled. This is a prospective comparison of prognostic impacts of grading schemes to address these issues. SAH patients were assessed using WFNS, H&H (including systemic disease), modified H&H (sans systemic disease) and followed up with Glasgow Outcome Score (GOS) at 3 months. Their performance characteristics were analysed as incremental ordinal variables and different grading scale dichotomies using rank-order correlation, sensitivity, specificity, positive predictive value, negative predictive value, Youden's J and multivariate analyses. A total of 1016 patients were studied. As univariate incremental variable, H&H sans systemic disease had the best negative rank-order correlation coefficient (-0.453) with respect to lower GOS (p H&H sans systemic disease had the greatest adjusted incremental impact of 0.72 (95% confidence interval (CI) 0.54-0.91) against a lower GOS as compared to 0.6 (95% CI 0.45-0.74) and 0.55 (95% CI 0.42-0.68) for H&H and WFNS grades, respectively. In multivariate categorical analysis, H&H grades 4-5 sans systemic disease had the greatest impact on unfavourable GOS with an adjusted odds ratio of 6.06 (95% CI 3.94-9.32). To conclude, H&H grading sans systemic disease had the greatest impact on unfavourable GOS. Though systemic disease is an important prognostic factor, it should be considered distinctly from grading. Appropriate cut-off values suggesting unfavourable outcome for H&H and WFNS were 4-5 and 3-5, respectively, indicating the importance of neurological deficits in addition to level of consciousness.

Do We Really Have an Age/H_0 Conflict?

Two independent methods for estimating the age of the universe can both be linked to the absolute magnitudes of the RR Lyrae stars, one based on stellar evolution in globular clusters and the other based on the Hubble Constant derived from globular clusters as distance indicators. The latter has recently been extracted from HST-WFPC2 data for globular clusters in the Coma Cluster galaxy IC 4051 (Baum et al. 1997, AJ, 113, 1483). If RR Lyrae stars are brighter than we have previously thought, the stellar-evolution age estimate is shortened whereas the Hubble age is increased, so we can ask a very simple question: For what RR Lyrae magnitude zero point would the stellar-evolution age coincide with the Hubble age, and is it a reasonable value? Allowing 1 Gyr for globular clusters to have formed, and assuming a classical Einstein-deSitter universe with Lambda = 0, I find the two ages to coincide if M_V(RR) ~ 0.16[Fe/H] + 0.46, which (among other things) puts the Large Magellanic Cloud at (m-M) = 18.78 +/- 0.17 mag. The implied age of the universe is 11.0 +/- 1.4 Gyr, and the corresponding H_0 = 59 +/- 8 km/s per Mpc.

We observe two distinct phases of Na x CoO 2 in the large Na-doping region (x≥0.75), a pure phase H 2 , and a mixed phase H 2 +H 3 . The H 2 phase is characterized by a steep increase of the Peltier conductivity α defined as J=α(-∇T), where J the thermoelectric current driven by the temperature gradient -∇T. The mixed-phase state H 2 +H 3 exhibits an unusual layered phase separation with conducting layers existing in parallel with insulating ones. At the critical doping x p ∼0.85, the figure-of-merit Z at 80 K is 40 times larger than that of the as-grown sample (x∼0.7). The Hall coefficient and magnetoresistance are also reported

We present new, high-quality multicolor observations of four recently discovered contact binaries, 1SWASP J064501.21+342154.9, 1SWASP J155822.10-025604.8, 1SWASP J212808.86+151622.0, and UCAC4 436-062932, and analyze their light curves to determine orbital and physical parameters using the modeling program of G. Djurašević. In the absence of spectroscopic observations, the effective temperatures of the brighter components are estimated from the color indices, and the mass ratios are determined with the q -search method. The analysis shows that all four systems are W UMa type binaries in shallow contact configurations, consisting of late-type main-sequence primaries and evolved secondaries with active surface regions (dark or bright spots) resulting from magnetic activity or ongoing transfer of thermal energy between the components. We compare the derived orbital and stellar parameters for these four variables with a large sample of previously analyzed W UMa stars and find that our results fit it well.

Using these rates, the $f_1(1285)$ mixing angle between strange and non-strange components of its wave function in the $q\\overline{q}$ structure model is determined to be $\\pm(24.0^{\\,+3.1\\,+0.6}_{\\,-2.6\\,-0.8})^{\\circ}$. Implications on the possible tetraquark nature of the $f_1(1285)$ are discussed.

Alopecia areata (AA) is a common autoimmune disease that presents with non-scarring alopecia. It is characterized by intra- or peri-follicular lymphocytic infiltrates composed of CD4+ and CD8+ T-cells on histology. To this day, few treatments are effective for AA. Here we present findings of using a low-level laser comb to alleviate the symptoms of AA in a C3H/HeJ mouse model for AA. Fourteen C3H/HeJ mice with induced AA were used in this study. Two were killed to confirm AA through histology. The remaining 12 mice were randomized into two groups; group I received HairMax LaserComb (wavelength: 655 nm, beam diameter lasers) for 20 s daily, three times per week for a total of 6 weeks; group II was treated similarly, except that the laser was turned off (sham-treated). After 6 weeks of LaserComb treatment, hair regrowth was observed in all the mice in group I (laser-treated) but none in group II (sham-treated). On histology, increased number of anagen hair follicles was observed in laser-treated mice. On the other hand, sham-treated mice demonstrated hair follicles in the telogen phase with no hair shaft. LaserComb seems to be an effective and convenient device for the treatment of AA in the C3H/HeJ mouse model. Human studies are required to determine the efficacy and safety of this device for AA therapy.

Given the bone tropism of prostate cancer, conventional imaging modalities poorly identify or quantify metastatic disease. {sup 89}Zr-huJ591 positron emission tomography (PET) imaging was performed in patients with metastatic prostate cancer to analyze and validate this as an imaging biomarker for metastatic disease. The purpose of this initial study was to assess safety, biodistribution, normal organ dosimetry, and optimal imaging time post-injection for lesion detection. Ten patients with metastatic prostate cancer received 5 mCi of {sup 89}Zr-huJ591. Four whole-body scans with multiple whole-body count rate measurements and serum activity concentration measurements were obtained in all patients. Biodistribution, clearance, and lesion uptake by {sup 89}Zr-huJ591 immuno-PET imaging was analyzed and dosimetry was estimated using MIRD techniques. Initial assessment of lesion targeting of {sup 89}Zr-huJ591 was done. Optimal time for imaging post-injection was determined. The dose was well tolerated with mild chills and rigors seen in two patients. The clearance of {sup 89}Zr-huJ591 from serum was bi-exponential with biological half-lives of 7 ± 4.5 h (range 1.1-14 h) and 62 ± 13 h (range 51-89 h) for initial rapid and later slow phase. Whole-body biological clearance was 219 ± 48 h (range 153-317 h). The mean whole-body and liver residence time was 78.7 and 25.6 h, respectively. Dosimetric estimates to critical organs included liver 7.7 ± 1.5 cGy/mCi, renal cortex 3.5 ± 0.4 cGy/mCi, and bone marrow 1.2 ± 0.2 cGy/mCi. Optimal time for patient imaging after injection was 7 ± 1 days. Lesion targeting of bone or soft tissue was seen in all patients. Biopsies were performed in 8 patients for a total 12 lesions, all of which were histologically confirmed as metastatic prostate cancer. One biopsy-proven lesion was not positive on {sup 89}Zr-huJ591, while the remaining 11 lesions were {sup 89}Zr-huJ591 positive. Two biopsy-positive nodal lesions were noted only on

LHCb experiment has been designed in order to do precise measurements of CP violation and rare decays with B mesons. In 2000, the collaboration decided to modify the spectrometer in order to minimize the amount of matter seen by particles and to optimize the trigger. This thesis was done in this context and is divided into 3 parts. The first part is relative to the electron identification and to the recovery of Bremsstrahlung photons emitted by electrons when they pass through matter. Electron identification is mainly based on information provided by calorimeter system but also uses RICH and muon system. A method based on reference histograms had been developed which combine information provided by these detectors. Electron identification efficiency, for electrons in ECAL acceptance is 95% and the pion mis-identification rates 0.8% with a 65% purity of electron sample. Bremsstrahlung recovery allows the selection of J/{phi} decaying in e{sup +}e{sup -} pair and of B{sub d}{sup 0} {yields} J/{phi}(ee)K{sub S}{sup 0} channel which are described in the second part. The selection of this channel was developed in order to get an acceptable selection efficiency with a good rejection of background. A set of kinematic and topological cuts were designed and total selection efficiency is 0.176%, corresponding to 28000 untagged events reconstructed by year, with a ratio B/S belonging to [0.017;0.069] (at 90% of confidence level) for inclusive bb-bar background. In the third part, B meson flavour tagging is presented. The addition of information provided by the vertex locator allows to reject electron coming from conversion and to improve slightly the performances. The LHCb sensibility to sin(2{beta}) from B{sup 0} {yields} J/{psi}K{sub S}{sup 0} decay is also determined. The statistical error, expected after one year of data collecting, corresponding to an integrated luminosity of 2 fb{sup -1} and bb-bar pair cross section of 0.5 mb, varies from 0.015 to 0.020 according to

Canonical grids of stellar evolutionary sequences have been computed for the helium mass-fraction abundances Y = 0.25, 0.29, and 0.33, and for iron abundances that vary from –2.4 to +0.4 (in 0.2 dex increments) when [α/Fe] =+0.4, or for the ranges –2.0 ≤ [Fe/H] ≤+0.6, –1.8 ≤ [Fe/H] ≤+0.6 when [α/Fe] =0.0 and –0.4, respectively. The grids, which consist of tracks for masses from 0.12 M{sub ⊙} to 1.1-1.5 M{sub ⊙} (depending on the metallicity) are based on up-to-date physics, including the gravitational settling of helium (but not metals diffusion). Interpolation software is provided to generate isochrones for arbitrary ages between ≈5 and 15 Gyr and any values of Y, [α/Fe], and [Fe/H] within the aformentioned ranges. Comparisons of isochrones with published color-magnitude diagrams (CMDs) for the open clusters M67 ([Fe/H] ≈0.0) and NGC 6791 ([Fe/H] ≈0.3) and for four of the metal-poor globular clusters (47 Tuc, M3, M5, and M92) indicate that the models for the observed metallicities do a reasonably good job of reproducing the locations and slopes of the cluster main sequences and giant branches. The same conclusion is reached from a consideration of plots of nearby subdwarfs that have accurate Hipparcos parallaxes and metallicities in the range –2.0 ≲ [Fe/H] ≲ –1.0 on various CMDs and on the (log T {sub eff}, M{sub V} ) diagram. A relatively hot temperature scale similar to that derived in recent calibrations of the infrared flux method is favored by both the isochrones and the adopted color transformations, which are based on the latest MARCS model atmospheres.

We present the results of a program to map the Sh2-235 molecular cloud complex in the CO and 13CO J = 2 - 1 transitions using the Heinrich Hertz Submillimeter Telescope. The map resolution is 38″ (FWHM), with an rms noise of 0.12 K brightness temperature, for a velocity resolution of 0.34 km s-1. With the same telescope, we also mapped the CO J = 3 - 2 line at a frequency of 345 GHz, using a 64 beam focal plane array of heterodyne mixers, achieving a typical rms noise of 0.5 K brightness temperature with a velocity resolution of 0.23 km s-1. The three spectral line data cubes are available for download. Much of the cloud appears to be slightly sub-thermally excited in the J = 3 level, except for in the vicinity of the warmest and highest column density areas, which are currently forming stars. Using the CO and 13CO J = 2 - 1 lines, we employ an LTE model to derive the gas column density over the entire mapped region. Examining a 125 pc2 region centered on the most active star formation in the vicinity of Sh2-235, we find that the young stellar object surface density scales as approximately the 1.6-power of the gas column density. The area distribution function of the gas is a steeply declining exponential function of gas column density. Comparison of the morphology of ionized and molecular gas suggests that the cloud is being substantially disrupted by expansion of the H II regions, which may be triggering current star formation.

We have calculated highly accurate elastic and charge transfer cross sections for proton-hydrogen scattering at energies 0.0001-10 eV, using fully quantal approach (P.S. Krstic and D.R. Schultz, J. Phys. B 32, 3485 (1999)). A number of resonances are observed. We calculate the positions and widths of the shape resonances in the effective potentials for various orbital angular momenta (J. H. Macek and S. Yu. Ovchinnikov, Phys. Rev. A 50, 468 (1994)). These correlate well with the observed resonances.

With increasing annealing temperature (T anneal ), the magnitude of the electric fields for the antiferroelectric-to-ferro-electric (E AF ) and ferroelectric-to-antiferroelectric (E FA ) transition of a 9.2 nm thick Hf 0.3 Zr 0.7 O 2 film decreased. The energy storage densities of the Hf 0.3 Zr 0.7 O 2 films crystallized at 400 C, 500 C, and 600 C were as large as 42.2 J/cm 3 , 40.4 J/cm 3 , and 28.3 J/cm 3 , respectively, at the electric field of 4.35 MV/cm. The maximum dielectric constant of the Hf 0.3 Zr 0.7 O 2 film crystallized at 600 C was the largest (∝46) as it had the smallest E AF and E FA , whereas the leakage current density of the film crystallized at 400 C was the smallest. The 400 C of T anneal was the optimum condition for energy storage application. (copyright 2014 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim) (orig.)

In this work, we study systems composed of a ρ/ω and B* meson pair. We find three bound states in isospin, spin-parity channels (1/2, 0{sup +}), (1/2, 1{sup +}), and (1/2, 2{sup +}). The state with J = 2 can be a good candidate for the B{sub 2}{sup *} (5747). We also study the ρB system, and a bound state with mass 5728 MeV and width around 20 MeV is obtained, which can be identified with the B1(5721) resonance. In the case of I = 3/2, one obtains repulsion and, thus, no exotic (molecular) mesons in this sector are generated in the approach. (orig.)

Absorption spectra of H2-H2 pairs in the fundamental band

Meyer, W.; Borysow, A.; Frommhold, L.

1989-01-01

For the computation of the induced-dipole moment, the collisional complex consisting of two H 2 molecules is treated like one molecule in the self-consistent-field and size-consistent, coupled electron pair approximations that separates correctly at distant range. The basis set accounts for 95% of the correlation energies. The radial transition matrix elements of the induced-dipole components are obtained for the two cases v 1 =v 2 =0 and v 1 =0,v 2 =1, where the v i are the vibrational quantum numbers of the interacting H 2 molecules (i=1 or 2). The dependence of these elements on the most important rotational states (j 1 , j 1 ',j 2 ,j 2 '=0,...,3) involved is obtained and seen to be significant in the fundamental band. The results are recast in a simple, but accurate analytical form that is used in a quantum formalism for computations of the spectral moments (sum rules) and line shapes of the collision-induced absorption spectra of molecular hydrogen pairs in the infrared 2.4-μm band. The calculations are based on a proven isotropic potential model that we have extended to account for effects of vibrational excitations. Numerical consistency of the line-shape calculations with the sum rules is observed at the 1% level. The comparison of the computational results with the available measurements at temperatures from 20 to 300 K shows agreement within the estimated uncertainties of the best measurements (∼10%). This fact suggests that theory is capable of predicting these spectra reliably at temperatures for which no measurements exist, with an accuracy that compares favorably with that of good laboratory measurements

We demonstrate that dispersion theory allows one to deduce crucial information on πη scattering from the final-state interactions of the light mesons visible in the spectral distributions of the decays B̄{sub d}{sup 0}→J/ψ(π{sup 0}η,K{sup +}K{sup −},K{sup 0}K̄{sup 0}). Thus high-quality measurements of these differential observables are highly desired. The corresponding rates are predicted to be of the same order of magnitude as those for B̄{sub d}{sup 0}→J/ψπ{sup +}π{sup −} measured recently at LHCb, letting the corresponding measurement appear feasible.
COMMENT ON THE BLACK HOLE RECOIL CANDIDATE QUASAR SDSS J092712.65+294344.0

The Sloan Digital Sky Survey (SDSS) quasar J092712.65+294344.0 has been proposed as a candidate for a supermassive black hole (∼10 8.8 M sun ) ejected at high speed from the host galactic nucleus by gravitational radiation recoil, or alternatively for a supermassive black hole binary. This is based on a blueshift of 2650 km s -1 of the broad emission lines ('b-system') relative to the narrow emission lines ('r-system') presumed to reflect the galaxy velocity. New observations with the Hobby-Eberly Telescope (HET) confirm the essential features of the spectrum. We note a third redshift system, characterized by weak, narrow emission lines of [O III] and [O II] at an intermediate velocity 900 km s -1 redward of the broad-line velocity ('i-system'). A composite spectrum of SDSS QSOs similar to J0927+2943 illustrates the feasibility of detecting the calcium K absorption line in spectra of sufficient quality. The i-system may represent the QSO host galaxy or a companion. Photoionization requires the black hole to be ∼3 kpc from the r-system emitting gas, implying that we are observing the system only 10 6 yr after the recoil event and contributing to the low probability of observing such a system. The HET observations give an upper limit of 10 km s -1 per year on the rate of change of the velocity difference between the r- and b-systems, constraining the orbital phase in the binary model. These considerations and the presence of a cluster of galaxies apparently containing J0927+2943 favor the idea that this system represents a superposition of two active galactic nuclei.
Treatment of H0 and H- beams spilled at the stripper foil at full energy charge-exchange injection scheme

1991-01-01

The charge-exchange injection into a synchrotron to generate high-intensity pulsed proton beams for a spallation neutron source is reviewed while focusing on the treatment of H 0 and H - beams spilled at the stripper foil. After charge-exchange injection is briefly outlined, scattering by foil atoms and causes to spill H 0 and H - beams are described. These spilled beams can amount to several μA and should be carefully treated. It is then shown that a direct H - injection system needs to be considerably long and requires a very long straight section. Because of its simplicity, two-step H 0 injection has very wide applicability to various types of rings. However, it has a problem of emittance growth due to angular divergence in the stripper magnet and an ionoptical mismatch at the stripper foil. These problems are discussed, including a new proposal for a measure to remedy this problem. The laser photoionization injection is also briefly mentioned. (author)

To explore the effects of HbJ Bangkok, HbE, HbG Taipei, and α-thalassemia HbH on the results of HbA1c assessment using ion-exchange high-performance liquid chromatography (IE-HPLC). We enrolled five patients in which the results of the IE-HPLC HbA1c assay were inconsistent with the average levels of FBG. We performed hemoglobin capillary (Hb) electrophoresis using whole-blood samples. We also sequenced the genes encoding Hb using dideoxy-mediated chain termination and analyzed HbA1c using borate affinity HPLC (BA-HPLC) and turbidimetric inhibition immunoassay (TINIA). Two patients had the HbJ Bangkok variant. Hb genotypes of these patients were β 41-42 /β J Bangkok and β N /β J Bangkok , and the content of HbJ Bangkok was 93.9% and 52.4%, respectively. The remaining three patients had the following: HbE (β N /β E Hb genotype, 23.6% HbE content), HbG Taipei (β N /β G Taipei Hb genotype, 39.4% HbG Taipei content), and α-thalassemia HbH (6.1% HbH content, 2.8% Hb Bart's content). In the patients with β-thalassemia and HbJ Bangkok variants, the presence of the variants interfered with the results of HbA1c analyses using IE-HPLC and TINIA; in the remaining four patients, there was interference with the results of HbA1c IE-HPLC but not with the TINIA assay. There was no interference with BA-HPLC HbA1c results. HbJ Bangkok, HbE, HbG Taipei Hb, and α-thalassemia HbH disease cause varying degrees of interference with the analysis of HbA1c using IE-HPLC. In these patients, we suggest using methods free from such interference for the analysis of HbA1c and other indicators to monitor blood glucose levels. © 2017 Wiley Periodicals, Inc.

The cracking behavior in H-implanted Si/B-doped Si0.70Ge0.30/Si structures after thermal annealing was investigated. The crack formation position is found to closely correlate with the thickness of the buried Si0.70Ge0.30 layer. For H-implanted Si containing a buried 3-nm-thick B-doped Si0.70Ge0.30 layer, localized continuous cracking occurs at the interfaces on both sides of the Si0.70Ge0.30 interlayer. Once the thickness of the buried Si0.70Ge0.30 layer increases to 15 and 70 nm, however, a continuous sharp crack is individually observed along the interface between the Si substrate and the B-doped Si0.70Ge0.30 interlayer. We attribute this exceptional cracking behavior to the existence of shear stress on both sides of the buried Si0.70Ge0.30 layer and the subsequent trapping of hydrogen, which leads to a crack in a well-controlled manner. This work may pave the way for high-quality Si or SiGe membrane transfer in a feasible manner, thus expediting its potential applications to ultrathin silicon-on-insulator (SOI) or silicon-germanium-on-insulator (SGOI) production.
Variation of the Moyer Model Parameter, H0, with primary proton energy

1982-08-01

Experimental values of the Moyer Model Parameter H 0 were summarized and presented as a function of proton energy, E/sub p/. The variation of H 0 (E/sup p/) with E/sup p/ was studied by regression analysis. Regression Analysis of the data under log-log transformation gave a best value for the exponent m of 0.77 +- 0.26, but a t-test did not reject m = 1 (p +- 20%). Since m = 1 was not excluded, and a Fisher's F-test did not exclude linearity, a linear regression analysis was performed. A line passing through the origin was not rejected (Student's t-test, p = 30%) and has the equation: H 0 (E/sup p/ = (1.61 +- 0.19) x 10 -13 Sv.m 2 /GeV to be compared with a value of (1.65 +- 0.21) x 10 -13 Sv.m 2 /GeV published by Stevenson et al

SDSS J080531.84+481233.0 is a closely separated, very-low-mass (VLM) binary identified through combined-light spectroscopy and confirmed as an astrometric variable. Here we report four years of radial velocity monitoring observations of the system that reveal significant and periodic variability, confirming the binary nature of the source. We infer an orbital period of 2.02 ± 0.03 years, a semimajor axis of 0.76{}-0.06+0.05 au, and an eccenticity of 0.46 ± 0.05, consistent with the amplitude of astrometric variability and prior attempts to resolve the system. Folding in constraints based on the spectral types of the components (L4 ± 0.7 and T5.5 ± 1.1), corresponding effective temperatures, and brown dwarf evolutionary models, we further constrain the orbital inclination of this system to be nearly edge-on (90° ± 19°), and deduce a large system mass ratio (M 2/M 1 = {0.86}-0.12+0.10), substellar components (M 1 = {0.057}-0.014+0.016 M ⊙, M 2 = {0.048}-0.010+0.008 M ⊙), and a relatively old system age (minimum age = {4.0}-1.2+1.9 Gyr). The measured projected rotational velocity of the primary ({V}{rot}\\sin I = 34.1 ± 0.7 km s-1) implies that this inactive source is a rapid rotator (period ≲ 3 hr) and a viable system for testing spin-orbit alignment in VLM multiples. Robust model-independent constraints on the component masses may be possible through measurement of the reflex motion of the secondary at wavelengths in which it contributes a greater proportion of the combined luminence, while the system may also be resolvable through sparse-aperature mask interferometry with adaptive optics. The combination of well-determined component atmospheric properties and masses near and/or below the hydrogen minimum mass make SDSS J0805+4812AB an important system for future tests of brown dwarf evolutionary models. Some of the data presented herein were obtained at the W.M. Keck Observatory, which is operated as a scientific partnership among the California

We present measurements of the dust attenuation of H{alpha}-selected emission-line galaxies at z = 0.8 from the NewH{alpha} narrowband survey. The analysis is based on deep follow-up spectroscopy with Magellan/IMACS, which captures the strong rest-frame optical emission lines from [O II] {lambda}3727 to [O III] {lambda}5007. The spectroscopic sample used in this analysis consists of 341 confirmed H{alpha} emitters. We place constraints on the active galactic nucleus (AGN) fraction using diagnostics that can be applied at intermediate redshift. We find that at least 5% of the objects in our spectroscopic sample can be classified as AGNs and 2% are composite, i.e., powered by a combination of star formation and AGN activity. We measure the dust attenuation for individual objects from the ratios of the higher order Balmer lines. The H{beta} and H{gamma} pair of lines is detected with S/N > 5 in 55 individual objects and the H{beta} and H{delta} pair is detected in 50 individual objects. We also create stacked spectra to probe the attenuation in objects without individual detections. The median attenuation at H{alpha} based on the objects with individually detected lines is A(H{alpha}) = 0.9 {+-} 1.0 mag, in good agreement with the attenuation found in local samples of star-forming galaxies. We find that the z = 0.8 galaxies occupy a similar locus of attenuation as a function of magnitude, mass, and star formation rate (SFR) as a comparison sample drawn from the SDSS DR4. Both the results from the individual z = 0.8 galaxies and from the stacked spectra show consistency with the mass-attenuation and SFR-attenuation relations found in the local universe, indicating that these relations are also applicable at intermediate redshift.

Biochar as ecologically clean and stable form of carbon has complex of physical and chemical properties which make it a potentially powerful soil amendment (Mutezo, 2013). Therefore during the last decade the biochar application as soil amendment has been a matter for a great number of investigations. For the ecological viewpoint the trend of decreasing of soil organic matter in European agricultural land is a major problem. Society is faced with the task to find possibilities to stabilize or increase soil organic matter content in soil and quality. The availability of different functional groups (e.g. carboxylic, phenolic, acidic, alcoholic, amine, amide) allows soil organic matter to buffer over a wide range of soil pH values (Krull et al. 2004). Therefore the loss of soil organic matter also reduces cation exchange capacity resulting in lower nutrient retention (Kimetu et al. 2008). Biochar can retain elements in soil directly through the negative charge that develops on its surfaces, and this negative charge can buffer acidity in the soil. There are lack of investigations about the effect of biochar to soil pH buffering properties, The aim of our investigation was to investigate the changes in soil pH buffer capacity in a result of addition of carbonizated material to temperate region soils. In the experiment different kind of softwood biochars, activated carbon and different soil types with various organic matter and pH were used. The study soils were Albeluvisols, Leptosols, Cambisols, Regosols and Histosols . In the experiment the series of the soil: biochar mixtures with the biochar content 0 to 100% were used. The times of equiliberation between solid and liquid phase were from 1 to 168 hours. The suspension of soil: biochar mixtures was titrated with HCl solution. The titration curves were established and pH buffer capacities were calculated for the pH interval from 3.0 to 10.0. The results demonstrate the dependence of pH buffer capacity from soil type
Dynamics of the D++ H2→ HD + H+ reaction at the low energy regime by means of a statistical quantum method

The D + +H 2 (v= 0, j= 0, 1) → HD+H + reaction has been investigated at the low energy regime by means of a statistical quantum mechanical (SQM) method. Reaction probabilities and integral cross sections (ICSs) between a collisional energy of 10 −4 eV and 0.1 eV have been calculated and compared with previously reported results of a time independent quantum mechanical (TIQM) approach. The TIQM results exhibit a dense profile with numerous narrow resonances down to E c ∼ 10 −2 eV and for the case of H 2 (v= 0, j= 0) a prominent peak is found at ∼2.5 × 10 −4 eV. The analysis at the state-to-state level reveals that this feature is originated in those processes which yield the formation of rotationally excited HD(v′= 0, j′ > 0). The statistical predictions reproduce reasonably well the overall behaviour of the TIQM ICSs at the larger energy range (E c ⩾ 10 −3 eV). Thermal rate constants are in qualitative agreement for the whole range of temperatures investigated in this work, 10–100 K, although the SQM values remain above the TIQM results for both initial H 2 rotational states, j= 0 and 1. The enlargement of the asymptotic region for the statistical approach is crucial for a proper description at low energies. In particular, we find that the SQM method leads to rate coefficients in terms of the energy in perfect agreement with previously reported measurements if the maximum distance at which the calculation is performed increases noticeably with respect to the value employed to reproduce the TIQM results

Provided that care is taken in adjusting the WATERGATE element of a {sup 1}H–{sup 15}N TROSY-HSQC experiment, such that neither the water magnetization nor the {sup 1}H{sup α} protons are inverted by its final 180° pulse, {sup 3}J{sub HNHα} couplings can be measured directly from splittings in the {sup 1}H dimension of the spectrum. With band-selective {sup 1}H decoupling, very high {sup 15}N resolution can be achieved. A complete set of {sup 3}J{sub HNHα} values, ranging from 3.4 to 10.1 Hz was measured for the 56-residue third domain of IgG-binding protein G (GB3). Using the H–N–C{sup α}–H{sup α} dihedral angles extracted from a RDC-refined structure of GB3, {sup 3}J{sub HNHα} values predicted by a previously parameterized Karplus equation agree to within a root-mean-square deviation (rmsd) of 0.37 Hz with the experimental data. Values measured for the Alzheimer’s implicated Aβ{sup 1−40} peptide fit to within an rmsd of 0.45 Hz to random coil {sup 3}J{sub HNHα} values.

A comparative analysis of understanding of the game by J. Huizinga, H. Hesse, E. Berne and L. Wittgenstein is being held. The result of this analysis is the assumption that H. Hesse and J. Huizinga are united by the fact that they both seek to ensure that the games remained appolonian element as a harmonious start in their understanding of the game - is a cultural universal. The position of the L.Wittgenstein differs significantly from the above indicated. For him the game - this is a language game that does not always harmonious, is not always clearly constructed composition typical for the games by H. Hesse. Playing field for L.Wittgenstein are «forms of life», which may indicate that his game as well as J. Huizinga, existential, the difference is only in the position of the interpreter, in a shift of emphasis from meaning to the action. J. Huizinga focuses on the classification of games that are played by the representatives of different cultures and L.Wittgenstein focuses on communication, without which it is impossible to play as such.

Low-temperature heat capacities of the 9-fluorenemethanol (C 14 H 12 O) have been precisely measured with a small sample automatic adiabatic calorimeter over the temperature range between T=78 K and T=390 K. The solid-liquid phase transition of the compound has been observed to be T fus =(376.567±0.012) K from the heat-capacity measurements. The molar enthalpy and entropy of the melting of the substance were determined to be Δ fus H m =(26.273±0.013) kJ · mol -1 and Δ fus S m =(69.770±0.035) J · K -1 · mol -1 . The experimental values of molar heat capacities in solid and liquid regions have been fitted to two polynomial equations by the least squares method. The constant-volume energy and standard molar enthalpy of combustion of the compound have been determined, Δ c U(C 14 H 12 O, s)=-(7125.56 ± 4.62) kJ · mol -1 and Δ c H m compfn (C 14 H 12 O, s)=-(7131.76 ± 4.62) kJ · mol -1 , by means of a homemade precision oxygen-bomb combustion calorimeter at T=(298.15±0.001) K. The standard molar enthalpy of formation of the compound has been derived, Δ f H m compfn (C 14 H 12 O,s)=-(92.36 ± 0.97) kJ · mol -1 , from the standard molar enthalpy of combustion of the compound in combination with other auxiliary thermodynamic quantities through a Hess thermochemical cycle

This Letter reports the discovery of a remarkably hard spectrum source, HESS J1641–463, by the High Energy Stereoscopic System (H.E.S.S.) in the very high energy (VHE) domain. HESS J1641–463 remained unnoticed by the usual analysis techniques due to confusion with the bright nearby source HESS J1640–465. It emerged at a significance level of 8.5 standard deviations after restricting the analysis to events with energies above 4 TeV. It shows a moderate flux level of φ(E>1 TeV) = (3.64 ± 0.44{sub stat} ± 0.73{sub sys}) × 10{sup –13} cm{sup –2} s{sup –1}, corresponding to 1.8% of the Crab Nebula flux above the same energy, and a hard spectrum with a photon index of Γ = 2.07 ± 0.11{sub stat} ± 0.20{sub sys}. It is a point-like source, although an extension up to a Gaussian width of σ = 3 arcmin cannot be discounted due to uncertainties in the H.E.S.S. point-spread function. The VHE γ-ray flux of HESS J1641–463 is found to be constant over the observed period when checking time binnings from the year-by-year to the 28 minute exposure timescales. HESS J1641–463 is positionally coincident with the radio supernova remnant SNR G338.5+0.1. No X-ray candidate stands out as a clear association; however, Chandra and XMM-Newton data reveal some potential weak counterparts. Various VHE γ-ray production scenarios are discussed. If the emission from HESS J1641–463 is produced by cosmic ray protons colliding with the ambient gas, then their spectrum must extend close to 1 PeV. This object may represent a source population contributing significantly to the galactic cosmic ray flux around the knee.

The protonated argon ion, {sup 36}ArH{sup +}, was recently identified in the Crab Nebula from Herschel spectra. Given the atmospheric opacity at the frequency of its J = 1-0 and J = 2-1 rotational transitions (617.5 and 1234.6 GHz, respectively), and the current lack of appropriate space observatories after the recent end of the Herschel mission, future studies on this molecule will rely on mid-infrared observations. We report on accurate wavenumber measurements of {sup 36}ArH{sup +} and {sup 38}ArH{sup +} rotation-vibration transitions in the v = 1-0 band in the range 4.1-3.7 μm (2450-2715 cm{sup –1}). The wavenumbers of the R(0) transitions of the v = 1-0 band are 2612.50135 ± 0.00033 and 2610.70177 ± 0.00042 cm{sup –1} (±3σ) for {sup 36}ArH{sup +} and {sup 38}ArH{sup +}, respectively. The calculated opacity for a gas thermalized at a temperature of 100 K and with a linewidth of 1 km s{sup –1} of the R(0) line is 1.6 × 10{sup –15} × N({sup 36}ArH{sup +}). For column densities of {sup 36}ArH{sup +} larger than 1 × 10{sup 13} cm{sup –2}, significant absorption by the R(0) line can be expected against bright mid-IR sources.
DISSECTING THE REGION OF 3EG J1837-0423 AND HESS J1841-055 WITH INTEGRAL

3EG J1837-0423 and HESS J1841-055 are two unidentified and peculiar high-energy sources located in the same region of the sky, separated by ∼1.4 deg. Specifically, 3EG J1837-0423 is a transient MeV object detected by EGRET only once during flaring activity that lasted a few days while HESS J1841-055 is a highly extended TeV source. We attempted to match the high-energy emission from the unidentified sources 3EG J1837-0423 and HESS J1841-055 with X-rays (4-20 keV) and soft γ-rays (20-100 keV) candidate counterparts detected through deep International Gamma-Ray Astrophysics Laboratory observations of the sky region. As a result we propose the Supergiant Fast X-ray Transient (SFXT) AX J1841.0-0536 as a possible candidate counterpart of 3EG J1837-0423, based on spatial proximity and transient behavior. Alternatively, AX J1841.0-0536 could be responsible for at least a fraction of the entire TeV emission from the extended source HESS J1841-055, based on a striking spatial correlation. In either case, the proposed association is also supported from an energetic standpoint by a theoretical scenario where AX J1841.0-0536 is a low magnetized pulsar which, due to accretion of massive clumps from the supergiant companion donor star, undergoes sporadic changes to transient Atoll-states where a magnetic tower can produce transient jets and as a consequence high-energy emission. In either case (by association with 3EG J1837-0423 or alternatively with HESS J1841-055), AX J1841.0-0536 might be the prototype of a new class of Galactic transient MeV/TeV emitters.

La{sub 0.7}Ca{sub 0.3−x}Ba{sub x}MnO{sub 3} nanoparticles with the crystalline size d = 38 and 39 nm for x = 0.025, and 0.05, respectively, were synthesized by utilizing the solid-state reaction and mechanical ball milling methods. We have used the Banerjee's criteria, the mean-field, and the thermodynamic theories, and isothermal magnetization, M(H), data around Curie temperature (T{sub C}) to investigate the magnetic phase transformation and the temperature (T) and magnetic field (H) dependences of magnetic entropy change, ΔS{sub m}(T, H), for nanoparticles. These exhibit the samples undergoing a second-order magnetic phase transition with an existence of the short-range ferromagnetic order in the samples. Under an applied magnetic field change ΔH = 30 kOe, the maximum value of ΔS{sub m} (denoted as |ΔS{sub max}|) are obtained about 4.4 J kg{sup −1} K{sup −1} corresponding to a relative cooling power (RCP) value about 140 J kg{sup −1}. Field dependences of |ΔS{sub max}| and RCP can be expressed by the power laws, |ΔS{sub max}| = a × H{sup n} and RCP = b × H{sup N}, where a and b are coefficients, n and N are the field exponents, respectively. Interestingly, all the ΔS{sub m}(T, H) curves measured at different applied fields are collapsed onto a universal curve, ΔS{sub m}(T, H)/ΔS{sub max} versus θ = (T − T{sub C})/(T{sub r} − T{sub C}), where T{sub r} is the reference temperature. - Highlights: • An existence of the short-range FM order in the La{sub 0.7}Ca{sub 0.3−x}Ba{sub x}MnO{sub 3} nanoparticles. • High magnetic entropy change, wide operative temperature range, and high RCP value. • Field dependences of |ΔS{sub max}| and RCP can be expressed by the power laws. • All the ΔS{sub m}(T, H) data are followed a universal master curve.

Non-invasive detection of 2-hydroxyglutarate (2HG) by magnetic resonance spectroscopy is attractive since it is related to tumor metabolism. Here, we compare the detection accuracy of 2HG in a controlled phantom setting via widely used localized spectroscopy sequences quantified by linear combination of metabolite signals vs. a more complex approach applying a J-difference editing technique at 9.4 T. Different phantoms, comprised out of a concentration series of 2HG and overlapping brain metabolites, were measured with an optimized point-resolved-spectroscopy sequence (PRESS) and an in-house developed J-difference editing sequence. The acquired spectra were post-processed with LCModel and a simulated metabolite set (PRESS) or with a quantification formula for J-difference editing. Linear regression analysis demonstrated a high correlation of real 2HG values with those measured with the PRESS method (adjusted R-squared: 0.700, p < 0.001) as well as with those measured with the J-difference editing method (adjusted R-squared: 0.908, p < 0.001). The regression model with the J-difference editing method however had a significantly higher explanatory value over the regression model with the PRESS method (p < 0.0001). Moreover, with J-difference editing 2HG was discernible down to 1 mM, whereas with the PRESS method 2HG values were not discernable below 2 mM and with higher systematic errors, particularly in phantoms with high concentrations of N-acetyl-asparate (NAA) and glutamate (Glu). In summary, quantification of 2HG with linear combination of metabolite signals shows high systematic errors particularly at low 2HG concentration and high concentration of confounding metabolites such as NAA and Glu. In contrast, J-difference editing offers a more accurate quantification even at low 2HG concentrations, which outweighs the downsides of longer measurement time and more complex postprocessing.

We report on the first broadband (1-200 keV) simultaneous Chandra-INTEGRAL observations of the recently discovered hard X-ray transient IGR J17177-3656 that took place on 2011 March 22, about two weeks after the source discovery. The source had an average absorbed 1-200 keV flux of about 8 x 10 -10 erg cm -2 s -1 . We extracted a precise X-ray position of IGR J17177-3656, α J2000 = 17 h 17 m 42. s 62, δ J2000 = -36 0 56'04.''5 (90% uncertainty of 0.''6). We also report Swift, near-infrared, and quasi-simultaneous radio follow-up observations. With the multi-wavelength information at hand, we propose IGR J17177-3656 is a low-mass X-ray binary, seen at high inclination, probably hosting a black hole.
Observations of the J = 2 → 1 transition of carbon monoxide in interstellar clouds

International Nuclear Information System (INIS)

Goldsmith, P.F.

1975-01-01

A spectral line radiometer system for operation at a wavelength of 1.3 mm (ν = 230 GHz) was constructed and used for astronomical observations. Observations were made of the 12 CO J = 2 → 1 line in nine astronomical sources. The 13 CO J = 2 → 1 line was measured in three molecular clouds--Orion A, NGC 2024, and OMC 2. The 12 C 18 O J = 2 → 1 line has been searched for, but not detected in Orion A. It was found that the temperatures of the 12 CO J = 1 → 0 lines are equal to or slightly lower than those of the corresponding J = 1 → 0 lines. The significance of the differences observed is reduced by the uncertainties in the calibrations at the two frequencies. These measurements are consistent with the 12 CO transitions being optically thick and thermalized. The 13 CO J = 2 → 1 lines are also approximately equal in intensity to the J = 1 → 0 lines. This is not consistent with both transitions being optically thin. The implications of these measurements in terms of clumped and low density models are discussed. In the proposed low density model which fits the CO data but encounters difficulties explaining the emission from other molecules, the molecular hydrogen density in the CO-emitting region is about 2 x 10 3 cm -3 . The nondetection of the J = 2 → 1 line of the 12 C 18 O species in Orion A places an upper limit on the hydrogen density of between 2 x 10 3 cm -3 and 4 x 10 +3 cm -3 , depending on the kinetic temperature in the cloud, for that component which is optically thin. A model for the central region of the Orion A molecular cloud is proposed in which high density (n/sub H/ greater than or equal to 10 6 cm -3 ) clumps occupying a few percent of the volume are embedded in a low density (n/sub H 2 / approximately 2 x 10 3 cm -3 ) interclump medium

Aims: We performed a multi-wavelength study toward the filamentary cloud G47.06+0.26 to investigate the gas kinematics and star formation. Methods: We present the 12CO (J = 1-0), 13CO (J = 1-0) and C18O (J = 1-0) observations of G47.06+0.26 obtained with the Purple Mountain Observation (PMO) 13.7 m radio telescope to investigate the detailed kinematics of the filament. Radio continuum and infrared archival data were obtained from the NRAO VLA Sky Survey (NVSS), the APEX Telescope Large Area Survey of the Galaxy (ATLASGAL), the Galactic Legacy Infrared Mid-Plane Survey Extraordinaire (GLIMPSE) survey, and the Multi-band Imaging Photometer Survey of the Galaxy (MIPSGAL). To trace massive clumps and extract young stellar objects in G47.06+0.26, we used the BGPS catalog v2.0 and the GLIMPSE I catalog, respectively. Results: The 12CO (J = 1-0) and 13CO (J = 1-0) emission of G47.06+0.26 appear to show a filamentary structure. The filament extends about 45' (58.1 pc) along the east-west direction. The mean width is about 6.8 pc, as traced by the 13CO (J = 1-0) emission. G47.06+0.26 has a linear mass density of 361.5 M⊙pc-1. The external pressure (due to neighboring bubbles and H II regions) may help preventing the filament from dispersing under the effects of turbulence. From the velocity-field map, we discern a velocity gradient perpendicular to G47.06+0.26. From the Bolocam Galactic Plane Survey (BGPS) catalog, we found nine BGPS sources in G47.06+0.26, that appear to these sources have sufficient mass to form massive stars. We obtained that the clump formation efficiency (CFE) is 18% in the filament. Four infrared bubbles were found to be located in, and adjacent to, G47.06+0.26. Particularly, infrared bubble N98 shows a cometary structure. CO molecular gas adjacent to N98 also shows a very intense emission. H II regions associated with infrared bubbles can inject the energy to surrounding gas. We calculated the kinetic energy, ionization energy, and thermal energy
J0023+0307: A Mega Metal-poor Dwarf Star from SDSS/BOSS

Only a handful of stars have been identified with an iron abundance [Fe/H] support from theoretical modeling, as the result of a top-heavy initial mass function. With zero or very low metal abundance limiting radiative cooling, the formation of low-mass stars could be inhibited. Currently, the star SDSS J1029+1729 sets the potential metallicity threshold for the formation of low-mass stars at {log}Z/{Z}ȯ ∼ -5. In our quest to push down the metallicity threshold we have identified SDSS J0023+0307, a primitive star with T eff = 6188 ± 84 K, and {log}g=4.9+/- 0.5, an upper limit [Fe/H] < ‑6.6, and a carbon abundance A(C) < 6.3. We find J0023+0307 to be one of the two most iron-poor stars known, and it exhibits less carbon that most of the stars at [Fe/H] < ‑5. Based on observations made with William Herschel Telescope (WHT) and the Gran Telescopio de Canarias (GTC), at the Observatorio del Roque de los Muchachos of the Instituto de Astrofísica de Canarias, in La Palma.

Using deep narrow-band and broad-band imaging, we identify 401 z approximately 0.40 and 249 z approximately 0.49 H-alpha line-emitting galaxies in the Subaru Deep Field. Compared to other H-alpha surveys at similar redshifts, our samples are unique since they probe lower H-alpha luminosities, are augmented with multi-wavelength (rest-frame 1000AA--1.5 microns) coverage, and a large fraction (20%) of our samples has already been spectroscopically confirmed. Our spectra allow us to measure the Balmer decrement for nearly 60 galaxies with H-beta detected above 5-sigma. The Balmer decrements indicate an average extinction of A(H-alpha)=0.7(uparrow){+1.4}_{-0.7} mag. We find that the Balmer decrement systematically increases with higher H-alpha luminosities and with larger stellar masses, in agreement with previous studies with sparser samples. We find that the SFRs estimated from modeling the spectral energy distribution (SED) is reliable---we derived an "intrinsic" H-alpha luminosity which is then reddened assuming the color excess from SED modeling. The SED-predicted H-alpha luminosity agrees with H-alpha narrow-band measurements over 3 dex (rms of 0.25 dex). We then use the SED SFRs to test different statistically-based dust corrections for H-alpha and find that adopting one magnitude of extinction is inappropriate: galaxies with lower luminosities are less reddened. We find that the luminosity-dependent dust correction of Hopkins et al. yields consistent results over 3 dex (rms of 0.3 dex). Our comparisons are only possible by assuming that stellar reddening is roughly half of nebular reddening. The strong correspondence argue that with SED modeling, we can derive reliable intrinsic SFRs even in the absence of H-alpha measurements at z approximately 0.5.

In as-cast Sm 2 Fe 17 the high amount of α-Fe caused by a peritectic reaction can be considerably reduced by a small addition of about 1 at% Zr. X-ray diffraction showed that as-cast Sm 10.5 Fe 88.5 Zr 1.0 mainly consists of a phase with the Th 2 Zn 17 -type structure and SmFe 3 . Non-homogenized Sm 10.5 Fe 88.5 Zr 1.0 was milled and (i) annealed in vacuum or (ii) treated with a hydrogenation-disproportionation-desorp tion-recombination (HDDR) process. The annealed and subsequently nitrogenated powder is magnetically anisotropic and has a coercivity μ 0J H C up to 2.0 T and an energy product (BH) max up to 136 kJ/m 3 . HDDR-treated and nitrogenated powder is isotropic and exhibits values of μ 0J H C = 3.1 T and (BH) max 103 kJ/m 3 . Consequently, Sm 10.5 Fe 88.5 Zr 1.0 N y (y ∼ 16) permanent magnets with very good properties can be prepared without the time-consuming homogenization procedure. (orig.)

1987-01-01

In this contribution the path independent J-integral according to J.R. Rice, respective J.D. Landes and J.A. Begley due to ASTME 813 is calculated by the product J pl = d v J el for 3 point bend type specimen. Here d v is the load point displacement up to the point of the onset of stable crack growth V, which is taken from the load versus load point displacement diagram and J el a value which is equivalent to K 2 /E, where K is the stress intensity factor (ASTME 399) and E is Young's modulus. The advantage of the new procedure is the simplicity of the test arrangement and of the evaluation with the determination of initiation point V without computer or other auxiliary equipment. (orig.)

Using a sample of 1.31 ×109 J /ψ events collected with the BESIII detector at the BEPCII collider, we study the decays of J /ψ →KSKL and KSKS . The branching fraction of J /ψ →KSKL is determined to be B (J /ψ →KSKL)=(1.93 ±0.01 (stat )±0.05 (syst ))×10-4 , which significantly improves on previous measurements. No clear signal is observed for the J /ψ →KSKS process, and the upper limit at the 95% confidence level for its branching fraction is determined to be B (J /ψ →KSKS)<1.4 ×10-8 , which improves on the previous searches by 2 orders in magnitude and reaches the order of the Einstein-Podolsky-Rosen expectation.

Measurement of the mixing-induced $CP$-violating phase $\\phi_s$ in $B^0_s$ decays is of prime importance in probing new physics. Here $7421 \\pm 105$ signal events from the dominantly $CP$-odd final state $J/\\psi\\pi^+\\pi^-$ are selected in 1 fb$^{-1}$ of $pp$ collision data collected at sqrt{s} = 7 TeV with the LHCb detector. A time-dependent fit to the data yields a value of $\\phi_s =-0.019^{+0.173+0.004}_{-0.174-0.003}$ rad, consistent with the Standard Model expectation. No evidence of direct $CP$ violation is found.

Extracellular vesicles (EVs) are now recognized as a fundamental way for cell-to-cell horizontal transfer of properties, in both physiological and pathological conditions. Most of EV-mediated cross-talk among cells depend on the exchange of proteins, and nucleic acids, among which mRNAs, and non-coding RNAs such as different species of miRNAs. Cancer cells, in particular, use EVs to discard molecules which could be dangerous to them (for example differentiation-inducing proteins such as histone H1.0, or antitumor drugs), to transfer molecules which, after entering the surrounding cells, are able to transform their phenotype, and even to secrete factors, which allow escaping from immune surveillance. Herein we report that melanoma cells not only secrete EVs which contain a modified form of H1.0 histone, but also transport the corresponding mRNA. Given the already known role in tumorigenesis of some RNA binding proteins (RBPs), we also searched for proteins of this class in EVs. This study revealed the presence in A375 melanoma cells of at least three RBPs, with apparent MW of about 65, 45 and 38 kDa, which are able to bind H1.0 mRNA. Moreover, we purified one of these proteins, which by MALDI-TOF mass spectrometry was identified as the already known transcription factor MYEF2.

The extended gamma-ray source MGRO J1908+06, discovered by the Milagro air shower detector in 2007, has been observed for {approx}4 years by the ARGO-YBJ experiment at TeV energies, with a statistical significance of 6.2 standard deviations. The peak of the signal is found at a position consistent with the pulsar PSR J1907+0602. Parameterizing the source shape with a two-dimensional Gauss function, we estimate an extension of {sigma}{sub ext} = 0.{sup 0}49 {+-} 0.{sup 0}22, which is consistent with a previous measurement by the Cherenkov Array H.E.S.S. The observed energy spectrum is dN/dE = 6.1 {+-} 1.4 Multiplication-Sign 10{sup -13} (E/4 TeV){sup -2.54{+-}0.36} photons cm{sup -2} s{sup -1} TeV{sup -1}, in the energy range of {approx}1-20 TeV. The measured gamma-ray flux is consistent with the results of the Milagro detector, but is {approx}2-3 times larger than the flux previously derived by H.E.S.S. at energies of a few TeV. The continuity of the Milagro and ARGO-YBJ observations and the stable excess rate observed by ARGO-YBJ and recorded in four years of data support the identification of MGRO J1908+06 as the steady powerful TeV pulsar wind nebula of PSR J1907+0602, with an integrated luminosity over 1 TeV {approx} 1.8 times the luminosity of the Crab Nebula.
State-to-state dynamics of the H{sup *}(n) + HD → D{sup *}(n{sup ′}) + H{sub 2} reactive scattering

The state-to-state dynamics of the H{sup *}(n) + HD → D{sup *}(n{sup ′}) + H{sub 2} reactive scattering at the collision energy of 0.5 eV have been carried out for the first time by using H-atom Rydberg tagging time-of-flight technique. Experimental results show that the angular distribution of the total H{sub 2} products presents clearly forward-backward asymmetric, which considerably differs from that of the corresponding H{sup +} + HD → D{sup +} + H{sub 2} reaction predicted by previously theoretical calculations. Such disagreement between these two processes suggests that the Fermi independent-collider model is also not valid in describing the dynamics of isotopic variants of the H{sup *} + H{sub 2} reaction. The rotational state distribution of the H{sub 2} products demonstrates a saw-toothed distribution with odd-j{sup ′} > even-j{sup ′}. This interesting observation is strongly influenced by nuclear spin statistics.
Vibrational inelasticity in H2 collisions with He and Li+

The partially averaged version of classical S-matrix theory was applied to three-dimensional collisions of H 2 with He and Li + . For H 2 -Li + , cross-sections for the de-excitation of H 2 from (n 1 ,j 1 ) = (1,0) to the ground vibrational manifold were computed at a total energy of 1.2 eV and compared to previously done coupled channel calculations of Schaefer and Lester. The agreement is very good. For H 2 -He, the Kutzelnigg-Tsapline interaction potential was extended to small atom-diatom separations, the ab initio points were then fit to an analytic form, and cross sections for the de-excitation of H 2 from the states (n 1 ,j 1 ), n 1 = 1, j 1 = 0,2,4 to the ground vibrational manifold were computed at total energies of .9, 1.1, 1.3 and 1.5 eV. For comparison, coupled channel calculations were also performed on the system at the same energies. The agreement was poorer than in the H 2 -Li + case, for identifiable reasons. The cross sections were used to compute rate constants and relaxation times for the H 2 -He system. Comparison of these results with the results of experiment and of other calculations shows good agreement, certainly within the expected errors. (7 figs., 30 refs., 3 tables)
A model-independent analysis of final-state interactions in {overline{B}}_{d/s}^0to J/ψ π π

Exploiting B-meson decays for Standard Model tests and beyond requires a precise understanding of the strong final-state interactions that can be provided model-independently by means of dispersion theory. This formalism allows one to deduce the universal pion-pion final-state interactions from the accurately known ππ phase shifts and, in the scalar sector, a coupled-channel treatment with the kaon-antikaon system. In this work an analysis of the decays {overline{B}}_d^0to J/ψ {π}+{π}- and {overline{B}}_s^0to J/ψ {π}+{π}- is presented. We find very good agreement with the data up to 1.05 GeV in the ππ invariant mass, with a number of parameters reduced significantly compared to a phenomenological analysis. In addition, the phases of the amplitudes are correct by construction, a crucial feature for many CP violation measurements in heavy-meson decays.
Frequency-modulation transient absorption spectrum of the HCCl A 1A double-prime(0,0,0)left-arrow X 1A'(0,0,0) transition

The rotationally resolved spectrum of the HCCl A 1 A double-prime(0,0,0)left-arrow X 1 A'(0,0,0) transition between 12 230 and 12 410 cm -1 was obtained for the first time at Doppler-limited resolution using a frequency-modulation (FM) transient absorption technique. Five major subbands (K a =0 left-arrow 1, 1 left-arrow 0, 1 left-arrow 2, 2 left-arrow 1, and 2 left-arrow 3) of HC 35 Cl and one subband (K a =0 left-arrow 1) of HC 37 Cl were observed and assigned. In addition, the forbidden subband (K a =0 left-arrow 0) of HC 35 Cl was also observed. Thus far, we have assigned most (more than 70%) of the strong lines. The analysis of these subbands determines the geometry for the HCCl A(0,0,0) level: angle HCCl=134.7 degree and R C-Cl =1.623 A while R C-H is fixed at the corresponding value of CH 2 . The height of the barrier to linearity was found to be approximately 2170 cm -1 above the vibrationless level of the A state. The rotational structure of this spectrum shows irregular perturbations. Both random and J-dependent (anomalous K-type doubling) effects were observed. As in methylene, the perturbations most likely arise from Renner--Teller effect between the two singlet states in combination with spin--orbit coupling between the singlet and triplet states

BPH/2J hypertensive mice have an exaggerated sympathetic contribution to blood pressure (BP). Premotor sympathetic neurons within the rostroventrolateral medulla (RVLM) are a major source of sympathetic vasomotor tone and major site of action of the centrally acting sympatholytic agent, rilmenidine. The relative cardiovascular effect of rilmenidine in BPH/2J versus normotensive BPN/3J mice was used as an indicator of the involvement of the RVLM in the sympathetic contribution to hypertension in BPH/2J mice. BPH/2J and BPN/3J mice were pre-implanted with telemetry devices to measure BP in conscious unrestrained mice. Rilmenidine was administered acutely (n=7-9/group), orally for 14 days, at a wide range of doses (n=5/group), and also infused intracerebroventricularly for 7 days (n=6/group). Acute intraperitoneal rilmenidine induced greater depressor and bradycardic responses in BPH/2J than BPN/3J mice (PstrainBPH/2J mice during the dark (active) period (-6.5 ± 2 mmHg; P=0.006). Chronic orally administered rilmenidine (1-12 mg/kg per day) also had minimal effect on 24-h BP in both strains (P>0.16). The sympathetic vasomotor inhibitory effect of rilmenidine is minimal in both strains and similar in hypertensive BPH/2J and BPN/3J mice. Thus, hypertension in BPH/2J mice is not likely mediated by greater neuronal activity in the RVLM, and agents such as rilmenidine would be an ineffective treatment for this form of neurogenic hypertension.

In order to understand the excitation mechanisms of silicon monoxide (SiO) masers around long-period variables (LPVs), we have investigated distributions of the SiO v = 2 and v = 3 J = 1 → 0 masers around 12 LPVs by very long baseline interferometry (VLBI) observations with the VLBI Exploration of Radio Astrometry (VERA) and the Nobeyama 45 m telescopes. VLBI fringes of the v = 3 maser emission were detected for five LPVs. The composite maps of the v = 2 and v = 3 masers were made for T Cep, W Hya, WX Psc, and R Leo using the spectral line phase-referencing technique. The v = 2 maser spots were distributed in a ring-like form around the central stars, while it is difficult to recognize any specific morphology in the v = 3 maser distributions due to the small number of v = 3 spots detected. However in T Cep, we find that the distribution of the v = 3 maser spots correlates well with the v = 2 masers within a few milliarcseconds (0.2-0.3 au) in position and 1 km s-1 in line-of-sight velocity at the light curve phase of ϕ = 0.28 (ϕ = 0.0 and 1.0 correspond to the visible light maxima). This correlation implies that the mechanism of line-overlapping between the mid-infrared lines of H2O and SiO molecules works in T Cep at ϕ = 0.28. We discuss the possibility that the line-overlapping may work at the limited duration from the maximum to the minimum of the stellar light curve.

A study was made of the possibility of making Nb/sub 3/Al wires by interdiffusion between Al and Nb at relatively low temperatures (lower than 1000/sup 0/C). This method should allow the fabrication of a copper stabilized wire by coworking Nb and Al composites in a copper matrix before the diffusion treatment. Results concerning the diffusion temperature and time dependence of J/sub c/ and T/sub c/ are presented. While J/sub c/(64 kG) is quite high, of the order of 1.5 x 10/sup 5/ A/cm/sup 2/, T/sub c/ is 15.56/sup 0/K, lower than the usually reported value. X-ray measurements of the lattice parameter are also reported and correlated with the measured value of T/sub c/.

Angola has an extremely diverse HIV-1 epidemic fueled in part by the frequent interchange of people with the Democratic Republic of Congo (DRC) and Republic of Congo (RC). Characterization of HIV-1 strains circulating in Angola should help to better understand the origin of HIV-1 subtypes and recombinant forms and their transmission dynamics. In this study we characterize the first near full-length HIV-1 genomic sequences from HIV-1 infected individuals from Angola. Samples were obtained in 1993 from three HIV-1 infected patients living in Cabinda, Angola. Near full-length genomic sequences were obtained from virus isolates. Maximum likelihood phylogenetic tree inference and analyses of potential recombination patterns were performed to evaluate the sequence classifications and origins. Phylogenetic and recombination analyses revealed that one virus was a pure subtype J, another mostly subtype J with a small uncertain region, and the final virus was classified as a H/U/CRF02_AG recombinant. Consistent with their epidemiological data, the subtype J sequences were more closely related to each other than to other J sequences previously published. Based on the env gene, taxa from Angola occur throughout the global subtype J phylogeny. HIV-1 subtypes J and H are present in Angola at low levels since at least 1993. Low transmission efficiency and/or high recombination potential may explain their limited epidemic success in Angola and worldwide. The high diversity of rare subtypes in Angola suggests that Angola was part of the early establishment of the HIV-1 pandemic.

Full Text Available Los jóvenes son un colectivo de especial importancia para la prevención de enfermedades de transmisión sexual y para la promoción de la salud en general, por ello resulta de interés estudiar las causas y determinantes de sus conductas de salud. El objetivo de esta investigación consistió en estudiar el grado de relación existente entre la conducta de uso del preservativo y otros hábitos de salud, en jóvenes españoles de 14 a 24 años. La muestra estuvo formada por 2171 jóvenes de las comunidades autónomas de Galicia, Andalucía y Madrid. Los resultados indican la existencia de diferencias estadísticamente significativas en función del género. En general las chicas presentan hábitos más saludables, a excepción de la práctica deportiva y el uso sistemático del preservativo masculino. Asimismo, las variables práctica deportiva e higiene buco-dental se muestran como predictores confiables de la conducta de usar el preservativo.

A search for direct CP violation in D{sup 0}→h{sup −}h{sup +} (where h=K or π) is presented using data corresponding to an integrated luminosity of 1.0 fb{sup −1} collected in 2011 by LHCb in pp collisions at a centre-of-mass energy of 7 TeV. The analysis uses D{sup 0} mesons produced in inclusive semileptonic b-hadron decays to the D{sup 0}μX final state, where the charge of the accompanying muon is used to tag the flavour of the D{sup 0} meson. The difference in the CP-violating asymmetries between the two decay channels is measured to be ΔA{sub CP}=A{sub CP}(K{sup −}K{sup +})−A{sub CP}(π{sup −}π{sup +})=(0.49±0.30(stat)±0.14(syst))%. This result does not confirm the evidence for direct CP violation in the charm sector reported in other analyses.

This work presents measurements of two diffractive production ratio for heavy flavour physics with the use of a reconstructed J/Ψ → μ⁺μ^- sample in p$\\bar{p}$ collisions at √s = 1.96 TeV using the D0 detector at Fermilab Tevatron. These events were selected using the Luminosity Monitor detectors, the calorimeter system and the muon system in a pseudo-rapidity region with range 2.7 ≤ |η| ≤ 4.4. The measured ratio were estimated to be N$J/Ψ\\atop{diff}$/N$J/Ψ\\atop{total}$ = (1.74 ± 0.16(stat) {+-} 0.13(syst))% e N$b\\atop{diff}$/N$b\\atop{total}$ = (0.79 ± 0.11(stat) ± 0.23(syst))%.

Excitation relaxation and structure of TPPS4 J-aggregates

The energy relaxation kinetics and the structure of the J-aggregates of water-soluble porphyrin 5,10,15,20-tetrasulphonatophenyl porphine (TPPS 4 ) were investigated in aqueous medium by means of time-resolved fluorescence spectroscopy and confocal laser-scanning fluorescence microscopy. The excitation of the J-aggregates, at excitation intensities higher than ∼10 15 photons/cm 2 per pulse, results in a remarkable decrease of the fluorescence quantum yield and in the appearance of an additional, non-exponential energy relaxation channel with a decay constant that depends on the excitation intensity. This relaxation mechanism was attributed to the exciton single-singlet annihilation. The exciton lifetime in the absence of the annihilation was calculated to be ∼150 ps. Using exciton annihilation theory, the exciton migration within the J-aggregates could be characterized by determining the exciton diffusion constant (1.8±0.9) 10 -3 cm 2 /s and the hopping time (1.2±0.6) ps. Using the experimental data, the size of the J-aggregate could be evaluated and was seen to yield at least 20 TPPS 4 molecules per aggregate. It was shown by means of confocal fluorescence laser scanning microscopy that TPPS 4 does self-associate in polyvinyl alcohol (PVA) at acidic pH forming molecular macro-assemblies on a scale of ∼1 μm in PVA matrices

The statistical significance for both signals is in excess of 9 standard deviations. The following ratios of branching fractions are measured to be \\begin{equation*}BR( B^+_c \\rightarrow J/\\psi D_s^+)/BR( B^+_c \\rightarrow J/\\psi \\pi+ ) = 2.90 \\pm 0.57 \\pm 0.24$,\\end{equation*} \\begin{equation*}BR( B^+_c \\rightarrow J/\\psi D_s^{*+} ) / BR ( B^+_c \\rightarrow J/\\psi D_s^+ ) = 2.37 \\pm 0.56 \\pm 0.10, \\end{equation*} where the first uncertainties are statistical and the second systematic.

Rotational transitions in molecular hydrogen collisions are computed. The two most recently developed potential energy surfaces for the H 2 -H 2 system are used from the following works: [A.I. Boothroyd, P.G. Martin, W.J. Keogh, M.J. Peterson, J. Chem. Phys., 116 (2002) 666; P. Diep, J.K. Johnson, J. Chem. Phys., 113 (2000) 3480; P. Diep, J.K. Johnson, J. Chem. Phys., 112 (2000) 4465]. Cross-sections for rotational transitions 00 → 20, 22, 40, 42, 44 and corresponding rate coefficients are calculated using a quantum-mechanical approach. Results are compared for a wide range of kinetic temperatures 300 K ≤ T≤ 3000 K

CP violation and the mass generation problem, will be the two fundamental points for Particle Physics at the dawn of the third millennium. The BABAR experiment, which is installed at PEP-II SLAC B-factory, aims to study CP violation in the B meson systems. It will be then possible to test the standard model explanation of CP violation and may be to highlight new sources. In order to study CP violation with the BABAR experiment it is mandatory to identify most of the produced particles. The first part of this thesis presents the study we carried out on a project of Cherenkov aerogel threshold counters for separating pions from kaons in the momentum region between 0.5 and 4.3 GeV/c. This study includes: preliminary search on materials (reflecting wrappings, wavelength shifters and aerogel), cells and light guides geometry and prototype simulation. Test beam results have shown the feasibility of such a detector. The second part of this thesis deals with the CP parameter measurement that could be achieved at the BABAR experiment for the B{sup 0} {yields} J/{psi}K{sub S}{sup 0} channel, where the J/{psi} decays in lepton mode. The reconstruction efficiency, background level, tagging efficiency as well as the resolution on the B vertex positions are studied. The measurement of the expected asymmetry is made with a probabilistic method or a fit and the resolution on the parameter sin 2{beta} that could be achieved is estimated. It is then shown that an uncertainty of 0.075 on sin 2{beta} could be reached in 1 year of data taking at the BABAR experiment, corresponding to an integrated luminosity of 30 fbarn{sup -1}.

Influenza viruses are responsible for high morbidities in humans and may, eventually, cause pandemics. Herein, we compared the pathogenesis and host innate immune responses of a seasonal H1N1, two 2009 pandemic H1N1, and a human H5N1 influenza virus in experimental BALB/c and C57BL/6J mouse models. We found that both 2009 pandemic H1N1 isolates studied (A/Hamburg/05/09 and A/Hamburg/NY1580/09) were low pathogenic in BALB/c mice [log mouse lethal dose 50 (MLD(50)) >6 plaque-forming units (PFU)] but displayed remarkable differences in virulence in C57BL/6J mice. A/Hamburg/NY1580/09 was more virulent (logMLD(50) = 3.5 PFU) than A/Hamburg/05/09 (logMLD(50) = 5.2 PFU) in C57BL/6J mice. In contrast, the H5N1 influenza virus was more virulent in BALB/c mice (logMLD(50) = 0.3 PFU) than in C57BL/6J mice (logMLD(50) = 1.8 PFU). Seasonal H1N1 influenza revealed marginal pathogenicity in BALB/c or C57BL/6J mice (logMLD(50) >6 PFU). Enhanced susceptibility of C57BL/6J mice to pandemic H1N1 correlated with a depressed cytokine response. In contrast, enhanced H5N1 virulence in BALB/c mice correlated with an elevated proinflammatory cytokine response. These findings highlight that host determinants responsible for the pathogenesis of 2009 pandemic H1N1 influenza viruses are different from those contributing to H5N1 pathogenesis. Our results show, for the first time to our knowledge, that the C57BL/6J mouse strain is more appropriate for the evaluation and identification of intrinsic pathogenicity markers of 2009 pandemic H1N1 influenza viruses that are "masked" in BALB/c mice.

Highlights: • The H{sub 2} consumption of the catalyst increases after aging. • The availability of surface lattice oxygen could be improved after aging. • Sintering and encapsulation of Pt weaken H{sub 2} spillover mechanism. • Soot oxidation activity is closely related to reduction temperature. - Abstract: Pt/Ce{sub 0.27}Zr{sub 0.73}O{sub 2} and Pt/Ce{sub 0.27}Zr{sub 0.70}La{sub 0.03}O{sub x} catalysts, prepared by co-precipitation and impregnation methods, were thermally treated at different temperatures for 10 h and then characterized by X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET), X-ray photoelectron spectroscopy (XPS), H{sub 2} temperature-programmed reduction (H{sub 2}-TPR), thermogravimetric analysis (TGA) and soot temperature-programmed oxidation (soot-TPO). Due to thermal effect on the structural and textural properties, the aged catalysts show increased reduction temperatures. But, interestingly, more H{sub 2} consumption is detected, which would be ascribed to the increased mobility of bulk oxygen and surface lattice oxygen. The promoting and synergistic roles of Pt in H{sub 2}-TPR are discussed and it reveals that the sintering and encapsulation of Pt would weaken the H{sub 2} spillover mechanism and the addition of La is beneficial to stabilize the synergistic effect between Pt and Ce. On the other hand, a humble role of Pt on promoting soot oxidation activity is found in this study. Not all oxygen species available in H{sub 2}-TPR can be used for soot oxidation. The deactivation of the aged catalysts is closely related to the reduction temperature.

Effects of reagent rotational excitation on the H + CHD3 → H2 + CD3 reaction: A seven dimensional time-dependent wave packet study

International Nuclear Information System (INIS)

Zhang, Zhaojun; Zhang, Dong H.

2014-01-01

Seven-dimensional time-dependent wave packet calculations have been carried out for the title reaction to obtain reaction probabilities and cross sections for CHD 3 in J 0 = 1, 2 rotationally excited initial states with k 0 = 0 − J 0 (the projection of CHD 3 rotational angular momentum on its C 3 axis). Under the centrifugal sudden (CS) approximation, the initial states with the projection of the total angular momentum on the body fixed axis (K 0 ) equal to k 0 are found to be much more reactive, indicating strong dependence of reactivity on the orientation of the reagent CHD 3 with respect to the relative velocity between the reagents H and CHD 3 . However, at the coupled-channel (CC) level this dependence becomes much weak although in general the K 0 specified cross sections for the K 0 = k 0 initial states remain primary to the overall cross sections, implying the Coriolis coupling is important to the dynamics of the reaction. The calculated CS and CC integral cross sections obtained after K 0 averaging for the J 0 = 1, 2 initial states with all different k 0 are essentially identical to the corresponding CS and CC results for the J 0 = 0 initial state, meaning that the initial rotational excitation of CHD 3 up to J 0 = 2, regardless of its initial k 0 , does not have any effect on the total cross sections for the title reaction, and the errors introduced by the CS approximation on integral cross sections for the rotationally excited J 0 = 1, 2 initial states are the same as those for the J 0 = 0 initial state

The temperature dependence of the rate constants, for the reactions of hydrated electrons with H atoms, OH radicals and H2O2 has been determined. The reaction with H atoms, studied in the temperature range 20-250-degrees-C gives k(20-degrees-C) = 2.4 x 10(10) M-1 s-1 and the activation energy E......-1 and E(A) = 15.6 kJ mol-1 (3.7 kcal mol-1) measured from 5-150-degrees-C. Thus, the activation energy for all three fast reactions is close to that expected for diffusion controlled reactions. As phosphates were used as buffer system, the rate constant and activation energy for the reaction......(A) = 14.0 kJ mol-1 (3.3 kcal mol-1). For reaction with OH radicals the corresponding values are, k(20-degrees-C) = 3.1 x 10(10) M-1 s-1 and E(A) = 14.7 kJ mol-1 (3.5 kcal mol-1) determined in the temperature range 5-175-degrees-C. For reaction with H2O2 the values are, k(20-degrees-C) = 1.2 x 10(10) M-1 s...

$\\mathcal{CP}$ violating phase $\\phi_s$ and penguin pollution in $B_s^0\\to J/\\psi K^+K^-$ with LHCb

CERN Multimedia

Vazquez Sierra, Carlos

2015-01-01

CP violating phase φs appears in b → anti(c)cs transitions due to the interference between the direct decay and the decay after the Bs⁰-anti(Bs⁰) mixing. In SM, φs = -2βs + δP, where -2βs is related to CKM matrix elements and δP is the penguin phase where contributions due to penguin diagrams are taken into account, being this δP phase also the main source of theoretical uncertainty in φs. This φs phase is very sensitive to possible NP (new particles contributing to box diagrams during the mixing, several possible BSM scenarios are presented), so δP should be estimated in order to disentangle these penguin pollution contributions from possible NP contributions, φs(LHCb) = -2βs + δP + δNP. The decay Bs⁰ → J/ψ K⁺K⁻ is a golden decay for φs measurement: latest LHCb combined result also including Bs⁰ → J/ψ π⁺π⁻ measurements is φs = -0.010 ± 0.039 rad, which is in excellent agreement with SM. The penguin pollution phase δP can be estimated using B⁰ → J/ψ ρ⁰ and B...

The magnetic properties and magnetocaloric effect (MCE) in HoNi 1−x Cu x In (x=0, 0.1, 0.3, 0.4) compounds have been investigated. With the substitution of Cu for Ni, the Ho magnetic moment will cant from the c-axis, and form a complicated magnetic structure. These compounds exhibit two successive magnetic transitions with the increase in temperature. The large reversible magnetocaloric effects have been observed in HoNi 1−x Cu x In compounds around T ord , with no thermal and magnetic hysteresis loss. The large reversible isothermal magnetic entropy change (−ΔS M ) is 20.2 J/kg K and the refrigeration capacity (RC) reaches 356.7 J/kg for field changes of 5 T for HoNi 0.7 Cu 0.3 In. Especially, the value of −ΔS M (12.5 J/kg K) and the large RC (132 J/kg) are observed for field changes of 2 T for HoNi 0.9 Cu 0.1 In. Additionally, the values of RC are improved to 149 J/K for the field changes of 2 T due to a wide temperature span for the mix of HoNi 0.9 Cu 0.1 In and HoNi 0.7 Cu 0.3 In compounds with the mass ratio of 1:1. These compounds with excellent MCE are expected to have effective applications in magnetic refrigeration around 20 K. - Highlights: • For magnetic-field changes of 2 T, the values of RC are improved to 149 J/K. • MCEs of these compounds show no thermal and magnetic hysteresis. • Compounds show two successive magnetic transitions with the increase in temperature. • With the substitution of Cu for Ni, compounds form a complicated magnetic structure

A measurement of the parity-violating decay asymmetry parameter, $\\alpha_b$, and the helicity amplitudes for the decay $\\Lambda_b^0\\to J/\\psi(\\mu^+\\mu^-) \\Lambda^0 (p\\pi^-)$ is reported. The analysis is based on 1400 $\\Lambda_b^0$ and $\\bar{\\Lambda}_b^0$ baryons selected in $4.6~\\rm{fb}^{-1}$ of proton--proton collision data with a center-of-mass energy of 7 TeV recorded by the ATLAS experiment at the LHC. By combining the $\\Lambda_b^0$ and $\\bar{\\Lambda}_b^0$ samples under the assumption of $CP$ conservation, the value of $\\alpha_b$ is measured to be $0.30\\pm0.16 ({\\rm stat})\\pm 0.06 ({\\rm syst})$. This measurement provides a test of theoretical models based on perturbative QCD or heavy-quark effective theory.
Pressure-composition isotherms and thermodynamic properties of TiF3-enhanced Na2LiAlH6

The mixed alanate Na 2 LiAlH 6 was prepared by ball-milling and subsequent heat-treatment under H 2 pressure. After the synthesis, 2 mol% TiF 3 was added by ball-milling. Pressure-composition isotherms were measured for the Ti-enhanced material in the temperature range of 170-250 deg C. A van't Hoff plot was constructed using the equilibrium desorption plateau pressures. From this plot, a dissociation enthalpy of 56.4 ± 0.4 kJ/mol H 2 and a corresponding entropy of 137.9 ± 0.7 J/K mol H 2 was found for Na 2 LiAlH 6

We report the detection of {gamma}-ray pulsations ({ge}0.1 GeV) from PSR J2229+6114 and PSR J1048-5832, the latter having been detected as a low-significance pulsar by EGRET. Data in the {gamma}-ray band were acquired by the Large Area Telescope (LAT) aboard the Fermi Gamma-ray Space Telescope, while the radio rotational ephemerides used to fold the {gamma}-ray light curves were obtained using the Green Bank Telescope, the Lovell telescope at Jodrell Bank, and the Parkes Telescope. The two young radio pulsars, located within the error circles of the previously unidentified EGRET sources 3EG J1048-5840 and 3EG J2227+6122, present spin-down characteristics similar to the Vela pulsar. PSR J1048-5832 shows two sharp peaks at phases 0.15 {+-} 0.01 and 0.57 {+-} 0.01 relative to the radio pulse confirming the EGRET light curve, while PSR J2229+6114 presents a very broad peak at phase 0.49 {+-} 0.01. The {gamma}-ray spectra above 0.1 GeV of both pulsars are fit with power laws having exponential cutoffs near 3 GeV, leading to integral photon fluxes of (2.19 {+-} 0.22 {+-} 0.32) x 10{sup -7} cm{sup -2} s{sup -1} for PSR J1048-5832 and (3.77 {+-} 0.22 {+-} 0.44) x 10{sup -7} cm{sup -2} s{sup -1} for PSR J2229+6114. The first uncertainty is statistical and the second is systematic. PSR J1048-5832 is one of the two LAT sources which were entangled together as 3EG J1048-5840. These detections add to the growing number of young {gamma}-ray pulsars that make up the dominant population of GeV {gamma}-ray sources in the Galactic plane.
