Sample records for channel mass asymmetry

  1. Study of mass asymmetry effect in the entrance channel for deep inelastic collisions between heavy ions

    International Nuclear Information System (INIS)

    The reactions (52Cr+56Fe) and (16O+92Mo) were studied extensively to learn about the influence of the mass asymmetry of the entrance channel on Deep Inelastic Collisions (DIC). These two systems have very different entrance channel asymmetry but both of them lead to the same ensemble of nucleons. The incident energies were choosen to be 265 MeV for Cr and 187 MeV for O so that the maximum angular momentum is the same in both the cases. The experimental results of the quasi-symmetric system (Cr+Fe) show that a large number of fragments have the characteristic properties of fission fragments. However, comparison of these results with those of an asymmetric system (O+Mo), forming the same compound nucleus with higher excitation energy, leads to think that these events can not be accounted for fission. It has been shown that these events could be considered as DIC products. The distributions of different multidifferential observables were reproduced with the help of a diffusion model, and with the condition of introducing a notion of half life time of the composite system. The half-life, thus calculated, seems to vary as a function of mass asymmetry of the entrance channel: 20.10-22S for the system Cr+Fe, 2.10-22S for the system O+Mo and 10.10-22S for a third system 20Ca+64Ni which has an intermediate mass asymmetry. Further it seems that the evaporation residue cross section in symmetric systems is far less than what we can expect from classical calculations

    An experiment has been performed to explore the incomplete fusion (ICF) reaction dynamics in heavy ion induced reactions. Excitation functions (EFs) for eighteen evaporation residues (ERs) produced in the system {sup 20}Ne+{sup 165}Ho have been measured in the energy range Almost-Equal-To 88-164 MeV. Some of the ERs have significant contribution from precursor decay, which has been separated out from the measured cumulative cross-sections to get direct production cross-sections. Parameters of the statistical model code PACE-2 are optimized to reproduce the ERs populated in complete fusion reactions such as in xn and pxn channels. Using the same parameters, EFs for the residues produced in {alpha}-particle(s) emission channels have been calculated. A significant enhancement in the measured EFs of the ERs produced in {alpha}-particle(s) emission channels over the PACE-2 predictions have been observed which indicates the occurrence of incomplete fusion reaction process. In the ICF process the break-up of projectile {sup 20}Ne into {sup 4}He+{sup 16}O and/or {sup 8}Be+{sup 12}C takes place followed by fusion of one of the fragments with the target nucleus {sup 165}Ho. The present data analyses suggest that probability of incomplete fusion reaction increases with projectile energy. The ICF fraction F{sup ICF} has been estimated and found to increase with increasing mass-asymmetry [A{sub T}/(A{sub T}+A{sub P})] of the partners in entrance channel. It is also observed that critical angular momentum associated with incomplete fusion channels at higher projectile energy may be associated with Script-Small-L -values lower than that of peripheral collisions, indicating that the incomplete fusion competes with complete fusion even at angular momentum values little lower than critical angular momentum.

  3. Study of entrance channel mass-asymmetry effect on incomplete fusion of 16O with 175Lu at E < 10 MeV/nucleon

    International Nuclear Information System (INIS)

    In the present work, we have measured and analyzed the excitation functions of evaporation residues produced in 16O + 175Lu system at energies 4-7 Mev/nucleon. An attempt has been made to estimate the ICF contribution of the cross-section from the measured excitation function data and the dependence of ICF fraction on projectile energy and mass-asymmetry of the projectile-target combination

    A very general saddle point nuclear shape may be found as a solution of an integro-differential equation without giving apriori any shape parametrization. By introducing phenomenological shell corrections one obtains minima of deformation energy for binary fission of parent nuclei at a finite (non-zero) mass asymmetry. Results are presented for reflection asymmetric saddle point shapes of thorium and uranium even-mass isotopes with A=226-238 and A=230-238 respectively.

  5. Fish otolith mass asymmetry: morphometry and influence on acoustic functionality.

    Science.gov (United States)

    Lychakov, D V; Rebane, Y T

    2005-03-01

    The role of the fish otolith mass asymmetry in acoustic functionality is studied. The saccular, lagenar and utricular otoliths are weighted in two species of the Black Sea rays, 15 species of the Black Sea teleost fish and guppy fish. The dimensionless otolith mass asymmetry chi is calculated as ratio of the difference between masses of the right and left paired otoliths to average otolith mass. In the most fish studied the otolith mass asymmetry is within the range of -0.2 < chi < +0.2 (< 20%). We do not find specific fish species with extremely large or extremely small otolith asymmetry. The large otoliths do not belong solely to any particular side, left or right. The heavier otoliths of different otolithic organs can be located in different labyrinths. No relationship has been found between the magnitude of the otolith mass asymmetry and the length (mass, age) of the animal. The suggested fluctuation model of the otolith growth can interpret these results. The model supposes that the otolith growth rate varies slightly hither and thither during lifetime of the individual fish. Therefore, the sign of the relative otolith mass asymmetry can change several times in the process of the individual fish growth but within the range outlined above. Mathematical modeling shows that acoustic functionality (sensitivity, temporal processing, sound localization) of the fish can be disturbed by the otolith mass asymmetry. But this is valid only for the fish with largest otolith masses, characteristic of the bottom and littoral fish, and with highest otolith asymmetry. For most fish the values of otolith mass asymmetry is well below critical values. Thus, the most fish get around the troubles related to the otolith mass asymmetry. We suggest that a specific physicochemical mechanism of the paired otolith growth that maintains the otolith mass asymmetry at the lowest possible level should exist. However, the principle and details of this mechanism are still far from being

    We show that, if they exist, lepton number asymmetries ($L_\\alpha$) of neutrino flavors should be distinguished from the ones ($L_i$) of mass eigenstates, since Big Bang Nucleosynthesis (BBN) bounds on the flavor eigenstates cannot be directly applied to the mass eigenstates. Similarly, Cosmic Microwave Background (CMB) constraints on mass eigenstates do not directly constrain flavor asymmetries. Due to the difference of mass and flavor eigenstates, the cosmological constraint on the asymmetries of neutrino flavors can be much stronger than conventional expectation, but not uniquely determined unless at least the asymmetry of the heaviest neutrino is well constrained. Cosmological constraint on $L_i$ for a specific case is presented as an illustration.

  7. Top quark forward-backward asymmetry in the large invariant mass region

    International Nuclear Information System (INIS)

    The forward-backward asymmetry in top-pair production that was observed in 2008 gets a boost in a recent CDF publication. Not only has the forward-backward asymmetry been further confirmed, but also distributional preferences are shown. Strikingly, the forward-backward asymmetry is the most sizable in the large Mtt invariant mass region and in the large rapidity difference |Δy| region. Here we used our previously proposed t-channel exchanged W' boson to explain the new observations. We show that a new particle exchanged in the t channel generically gives rise to such observations. Furthermore, we show that the proposed W' can be directly produced in association with a top quark at the Tevatron and the LHC. We perform a signal-background analysis and show that such a W' is readily observed at the Tevatron with a 10 fb-1 luminosity and at the LHC-7 with just a 100 pb-1 luminosity.

  8. Influence of mass-asymmetry on incomplete fusion

    International Nuclear Information System (INIS)

    During the last few decades, fusion process in heavy ion induced reaction at energies near and above the Coulomb barrier has been extensively studied. At energies not too much above the barrier, the fusion process plays an important role in reaction dynamics. The widely used model PACE-2, describes the fusion cross-section. While at higher energies, fusion process gives the way to incomplete fusion (ICF), where projectile fragmentation takes place and decreasing the reaction cross-section corresponding to the fusion. The ICF cross-section as a function of entrance channel mass asymmetry has been explained in terms of the model based on the interaction barrier, critical angular momentum and critical distance of approach. In case of ICF, an incompletely fused composite system is formed, where partial linear momentum of the projectile is given to the target nucleus and relatively less nucleonic degrees-of-freedom are involved as compared to CF. This incompletely fused composite system having less charge and mass in-comparison to completely fuse composite nucleus

    We conjecture that three light Majorana neutrinos and their right-handed counterparts may have a universal geometric mass hierarchy. Incorporating this phenomenological conjecture with the Fritzsch texture of lepton mass matrices in a simple seesaw mechanism, we show that it is possible to simultaneously account for current neutrino oscillation data and the cosmological baryon number asymmetry via leptogenesis.

  10. Cold fission description with constant and varying mass asymmetries

    International Nuclear Information System (INIS)

    Different description for varying the mass asymmetry in the fragmentation process are used to calculate the cold fission barrier penetrability. The relevance of the appropriate choice for both the description of the pre-scission phase and inertia coefficient to unify alpha decay, cluster radioactivity, and spontaneous cold fission processes in the same theoretical framework is explicitly shown. We calculate the half-life of all possible partition modes of nuclei of A > 200 following the most recent Mass Table by Audi and Wapstra. It is shown that if one uses the description in which the mass asymmetry is maintained constant during the fragmentation process, the experimental half-life-values and mass yield of 234 U cold fission are satisfactorily reproduced.

  12. Channel Norm-Based User Scheduling Exploiting Channel Asymmetry in Base Station Cooperative Transmission Systems

    2010-01-01

    Base station cooperative transmission, which is also known as coordinated multi-point (CoMP) transmission, is a promising technique to improve spectrum efficiency in future cellular systems. However, they need large signalling overhead to gather the channel information. In this paper, we consider low feedback user scheduling in downlink coherent CoMP systems exploiting their inherent channel asymmetry. Through the analysis of the statistics of the angle between channel vectors and the tightness of a lower bound of the orthogonally projected norm, we show that channel norm provides sufficient information to judge the orthogonality among users in asymmetric channels. Based on this observation, we propose a channel norm-based user scheduler (NUS), a local channel aided NUS (LocalNUS) and a large-scale fading-based user scheduler (LUS). Simulation results show that the LocalNUS performs very close to the existing greedy user scheduler (GUS) and semi-orthogonal user scheduler (SUS) with full channel state informat...

    We demonstrate the role of the mass asymmetry on the balance energy (Ebal) by studying asymmetric reactions throughout the periodic table and over entire colliding geometry. Our results, which are almost independent of the system size and as well as of the colliding geometries indicate a sizeable effect of the asymmetry of the reaction on the balance energy.

    The forward-backward asymmetry (FBA) in top-pair production that was observed in 2008 gets a boost in a recent CDF publication. Not only has the FBA further been confirmed, but also distributional preferences are shown. Strikingly, the FBA is the most sizable in the large $M_{t\\bar t}$ invariant mass region and in the large rapidity difference $|\\Delta y|$ region. Here we used our previously proposed $t$-channel exchanged $W'$ boson to explain the new observations. We show that a new particle exchanged in the $t$-channel generically gives rise to such observations.

  15. Projectile - Mass asymmetry systematics for low energy incomplete fusion

    2015-01-01

    Full Text Available In the present work, low energy incomplete fusion (ICF in which only a part of projectile fuses with target nucleus has been investigated in terms of various entrance channel parameters. The ICF strength function has been extracted from the analysis of experimental excitation functions (EFs measured for different projectile-target combinations from near- to well above- barrier energies in 12C,16O(from 1.02Vb to 1.64Vb+169Tm systems. Experimental EFs have been analysed in the framework statistical model code PACE4 based on the idea of equilibrated compound nucleus decay. It has been found that the value of ICF fraction (FICF increases with incident projectile energy. A substantial fraction of ICF (FICF ≈ 7 % has been accounted even at energy as low as ≈ 7.5% above the barrier (at relative velocity νrel ≈0.027 in 12C+169Tm system, and FICF ≈ 10 % at νrel ≈0.014 in 16O+169Tm system. The probability of ICF is discussed in light of the Morgenstern’s mass-asymmetry systematics. The value of FICF for 16O+169Tm systems is found to be 18.3 % higher than that observed for 12C+169Tm systems. Present results together with the re-analysis of existing data for nearby systems conclusively demonstrate strong competition of ICF with CF even at slightly above barrier energies, and strong projectile dependence that seems to supplement the Morgenstern’s systematics.

  16. Influence of mass asymmetry in fusion cross section of intermediate weight ions

    International Nuclear Information System (INIS)

    The mass asymmetry degree effect on fusion, was investigated for different systems involving nucleus Aprojectie, Atarget ≤ 40, populating a compound nucleus. The following systems were studied: (19F + 19F), (12C + 26Mg) and (19F + 12C, 16O, 27Al, 40Ca) in the energy range of 32 ≤ Elab ≤ 72 MeV and angular range 60 ≤ Θ lab ≤ 280. The experimental method employed the time of flight technique, of the evaporation residuals. Analysis of excitation function indicate different behavior for symmetric and asymmetric systems suggesting that the presence of other more competitive processes is more pronounced in asymmetric entrance channels at high energies. These behaviors indicate that mass asymmetry is an important point in complete and incomplete fusion processes. (A.C.A.S.)

    We study the transverse flow throughout the mass asymmetry range as a function of the impact parameter, keeping the total mass of the system fixed.We find that the geometry of vanishing flow (GVF) i.e. the impact parameter at which flow vanishes and its mass dependence is quite sensitive to the mass asymmetry of the reaction. With increase in the mass asymmetry, the value of GVF decreases, while its mass dependence increases. Our results indicate the sizable role of mass asymmetry on GVF as o...

  18. Mass loss and asymmetries in the lines of Iota Coronae Borealis

    International Nuclear Information System (INIS)

    Recent observations by Smith and Parsons of the Hg--Mn star iota CrB have revealed slight asymmetries in the absorption lines. While these asymmetries are near the limits of detection at the resolution used, their appearance in several lines indicates that they are real. Proposed explanations of this phenomenon are not completely satisfactory. In this Letter it will be shown that the asymmetries are consistent with an accelerating radial flow of material in the photosphere of this star. The velocity needed to reproduce the observed asymmetry corresponds to a mass loss rate of roughly 10-7 M/sub solar mass/ yr-1

  19. Angular Anisotropy and Mass Asymmetry of Thorium-232 Fission Fragments

    International Nuclear Information System (INIS)

    A large number of experimental and theoretical papers on the angular distribution of the fission fragments of nuclei indicate that it is satisfactorily described by the parameters of the fissioning nucleus at the saddle point. The problem of the effect of these parameters on the distribution of the fragments according to mass has as yet found no generally accepted solution. It remains unclear to what extent the 'good' quantum numbers characteristic of the nucleus at the saddle point remain equally ''good'' when the nucleus passes from the saddle point to the moment of breakdown. If at the saddle point the nucleus has a set of different configurations, this must be apparent in some way in the distribution of the fragments by mass and in their angular distribution (via the moment of inertia of the nucleus). The paper investigates the angular anisotropy of fragments with different masses in the fission of thorium-232 by fast neutrons. The masses of the fragments were determined by simultaneous recording of the kinetic energy of paired fragments in a double ionization chamber with grids. The direction of flight of the fragments was determined using a mechanical collimator. The neutrons causing fission had an extended spectrum, but the contribution of fissions via the (n, n'f) reaction did not exceed a few per cent. The fragments were sorted out according to energy by a two-dimensional 128 x 128 channel analyser with a memory on ferrite. The dependence of angular anisotropy on the mass of the fragments and on their kinetic energy with fixed mass is discussed. The first dependence makes it possible to judge the degree to which the saddle point affects the distribution of the fragments according to mass, while the second gives information about the degree to which the configuration of the nucleus at the moment of breakdown affects the angular anisotropy of the fragments.

  20. Asymmetry and decoherence of a quantum channel in the quantum communication system of continuous variables

    International Nuclear Information System (INIS)

    Influences of an asymmetric noisy quantum channel on continuous variable entanglement and quantum teleportation are investigated. It is shown that when the resource of entanglement is a two-mode squeezed-vacuum state, the amount of the shared entanglement and the performance of the quantum teleportation are greater (smaller) in the symmetric quantum channel than in the asymmetric one if n-bar >n-barth (n-bar th) , where n-bar and n-barth are the average photon numbers of the two-mode squeezed-vacuum state and the thermal noise. When the quantum teleportation is carried out in the asymmetric quantum channel, introducing an additional loss makes better the performance of the quantum teleportation under certain conditions. The introduction of an additional loss makes smaller not only the shared entanglement but also the degree of the channel asymmetry

    The radiative neutrino mass model with an inert doublet scalar has been considered as a promising candidate which can explain neutrino masses, dark matter abundance and baryon number asymmetry if dark matter is identified with the lightest neutral component of the inert doublet. We reexamine these properties by imposing all the data of the neutrino oscillation, which are recently suggested by the reactor experiments. We find that the sufficient baryon number asymmetry seems not to be easily g...

  2. Microscopic-macroscopic models for fission of extreme mass asymmetry. Resume of Ph.D thesis

    International Nuclear Information System (INIS)

    This is an extended abstract of the Ph. D. thesis devoted to the microscopic-macroscopic nuclear models able to describe the fission processes with high mass asymmetry. The chapter one presents the pertinent research on nuclear cluster emission, both theoretical and experimental. The chapter two presents a new nuclear shape parametrization with three degrees of freedom: elongation, necking, and mass asymmetry. General features of three dimensional potential barrier behaviour are analysed for the case of high mass asymmetry for different neck geometries. The chapter number three gives the computing methods of the shell corrections adequate for the case of high mass asymmetries. A new extension of the two-center harmonic approach to the single-particle shell model in the case of high asymmetry is given. The fourth chapter is devoted to the nuclear dynamics of the decay processes in a broad range of mass asymmetry to include under the same formalism the cold fission, heavy-ion emission and alpha decay. Two original methods to obtain the likeliest fission pattern with the essential features of the three subdue processes are finally described. The methods developed in this thesis are illustrated on the case of 234 U fission with 28 Mg as cluster emission and with 100 Zr as light fission fragment. (M.I.C.). 9 Figs., 48 Refs

    The $t\\bar{t}$ charge asymmetry in proton-proton collisions at $\\sqrt{s}$=7 TeV is measured using the dilepton decay channel ($ee, e\\mu,$ or $\\mu\\mu$). The data correspond to a total integrated luminosity of 5.0 inverse-femtobarns, collected by the CMS experiment at the LHC. The top-antitop and lepton charge asymmetries, defined as the differences in absolute values of the rapidities between the reconstructed top quarks and antiquarks and of the pseudorapidities between the positive and negative leptons, respectively, are measured to be $A_C$ = -0.010 +/- 0.017 (stat.) +/- 0.008 (syst.) and $A_C^{lep}$ = 0.009 +/- 0.010 (stat.) +/- 0.006 (syst.). The lepton charge asymmetry is also measured as a function of the invariant mass, rapidity, and transverse momentum of the top-antitop system. All measurements are consistent with the expectations of the standard model.

  4. Top quark mass measurement in dilepton channel

    International Nuclear Information System (INIS)

    In this work, we measured the top quark mass in tt'-' events produced in pp'-' interactions at the center-of-mass energy 1.96 TeV using CDF detector. We used dilepton in tt'-' events where both W bosons from top quarks are decaying into leptons. The data sample corresponds to 340 pb-1. We found there 33 tt'-' candidates while expecting 10.5 ± 1.9 background events. In the measurement, we reconstruct one, representative mass for each event using the assumption about longitudinal momentum of in tt'-' system, in order to be able to kinematically solve the under-constrained system. The mass distributions (templates) are created for simulated signal and background events. Templates are parametrized in order to obtain smooth probability density functions. Likelihood maximization which includes these parametrized templates is then performed on reconstructed masses obtained from data sample in order to obtain final top quark mass estimate. The result of applying this procedure on data events is top quark mass estimate 169.5+7.7-7.2(stat.) ± 4.0(syst.) GeV/c2 for 30 out of 33 candidates, where the solution for top quark mass was found. This measurement was a part of first top quark mass measurement in dilepton channel at CDF in Run II. The top quark mass measured here is consistent with the CDF measurement in dilepton channel from Run I Mtop = 167.4 ± 10.3(stat.) ± 4.8(syst.) GeV/c2. Moreover, the combined result of four top quark mass measurements in dilepton channel from Run II (one of these four measurements is our measurement) Mtop = 167.9 ± 5.2(stat.) ± 3.7(syst.) GeV/c2 significantly (by ∼ 40%) improved the precision of top quark mass determination from Run I. It should be also noted, that this combined result is consistent with measurement obtained in 'lepton+jets' channel at CDF in Run II (Mtop = 173.5+3.9-3.8 GeV/c2). So, we don't have yet any indication about new physics beyond the Standard Model. My main contribution in this analysis was the optimization

    We perform a comprehensive analysis of target mass corrections (TMCs) to spin-averaged structure functions and asymmetries at next-to-leading order. Several different prescriptions for TMCs are considered, including the operator product expansion, and various approximations to it, collinear factorization, and xi-scaling. We assess the impact of each of these on a number of observables, such as the neutron to proton F{sub 2} structure function ratio, and parity-violating electron scattering asymmetries for protons and deuterons which are sensitive to gamma-Z interference effects. The corrections from higher order radiative and nuclear effects on the parity-violating deuteron asymmetry are also quantified.

  6. Cosmological measurement of neutrino mass in the presence of leptonic asymmetry

    International Nuclear Information System (INIS)

    We review some cosmological consequences of a relic lepton asymmetry in the form of neutrinos. A relic neutrino degeneracy enhances the contribution of massive neutrinos to the present energy density of the Universe, and modifies the power spectrum of radiation and matter. In particular we show that even the smallest neutrino mass consistent with the Super-Kamiokande data is relevant for cosmological models of structure formation and cosmic microwave background (CMB) anisotropies, provided that a relic neutrino asymmetry exists

  8. Influence of oscillatory quantum shielding on scattering-induced spin-asymmetry and spin-channel preference in quantum plasmas

    International Nuclear Information System (INIS)

    This paper is devoted to the oscillatory screening effect on the electron scattering spin-asymmetry and spin-channel preference in quantum plasmas. It is found that the oscillatory quantum screening effects enhance the spin-singlet electron-scattering channel, but suppress the spin-triplet electron-scattering channel for the forward and backward scattering directions with increasing wave number for small quantum wave numbers. It is also found that the preference of the spin-singlet scattering, including the influence of oscillatory quantum shielding, has been reduced with increasing quantum wave number. The variation of the angular averaged scattering spin-asymmetry phenomenon is also discussed. (paper)

  9. K+ Block Is the Mechanism of Functional Asymmetry in Bacterial Na(v) Channels.

    Crystal structures of several bacterial Na(v) channels have been recently published and molecular dynamics simulations of ion permeation through these channels are consistent with many electrophysiological properties of eukaryotic channels. Bacterial Na(v) channels have been characterized as functionally asymmetric, and the mechanism of this asymmetry has not been clearly understood. To address this question, we combined non-equilibrium simulation data with two-dimensional equilibrium unperturbed landscapes generated by umbrella sampling and Weighted Histogram Analysis Methods for multiple ions traversing the selectivity filter of bacterial Na(v)Ab channel. This approach provided new insight into the mechanism of selective ion permeation in bacterial Na(v) channels. The non-equilibrium simulations indicate that two or three extracellular K+ ions can block the entrance to the selectivity filter of Na(v)Ab in the presence of applied forces in the inward direction, but not in the outward direction. The block state occurs in an unstable local minimum of the equilibrium unperturbed free-energy landscape of two K+ ions that can be 'locked' in place by modest applied forces. In contrast to K+, three Na+ ions move favorably through the selectivity filter together as a unit in a loose "knock-on" mechanism of permeation in both inward and outward directions, and there is no similar local minimum in the two-dimensional free-energy landscape of two Na+ ions for a block state. The useful work predicted by the non-equilibrium simulations that is required to break the K+ block is equivalent to large applied potentials experimentally measured for two bacterial Na(v) channels to induce inward currents of K+ ions. These results illustrate how inclusion of non-equilibrium factors in the simulations can provide detailed information about mechanisms of ion selectivity that is missing from mechanisms derived from either crystal structures or equilibrium unperturbed free

    The scattering spin-asymmetry and spin channel preference in electron collisions are investigated in electron-hole plasmas. It is found that the Landau damping effect enhances the scattering channel preference for the spin-singlet electron scattering and suppresses the spin-triplet electron scattering except the scattering angle {theta}={pi}/2. It is also found that the spin-singlet electron scattering decreases with an increase of the quantum shielding distance. In addition, the Landau damping effect on the spin-asymmetry parameter is found to be more significant in the intermediate domain of the quantum Debye length.

    We discuss a model which would explain neutrino oscillation, dark matter, and baryon asymmetry of the Universe simultaneously by the physics at TeV scales. Tiny neutrino masses are generated at the three loop level due to the exact $Z_2$ symmetry, by which the stability of the dark matter candidate is also guaranteed. The extra Higgs doublet is required not only for the tiny neutrino masses but also for successful electroweak baryogenesis. The model provides various discriminative predictions...

  13. Nuclear-mass dependence of azimuthal beam-helicity and beam-charge asymmetries in deeply virtual Compton scattering

    The nuclear-mass dependence of azimuthal cross section asymmetries with respect to charge and longitudinal polarization of the lepton beam is studied for hard exclusive electroproduction of real photons. The observed beam-charge and beam-helicity asymmetries are attributed to the interference between the Bethe-Heitler and deeply virtual Compton scattering processes. For various nuclei, the asymmetries are extracted for both coherent and incoherent-enriched regions, which involve different (combinations of) generalized parton distributions. For both regions, the asymmetries are compared to those for a free proton, and no nuclear-mass dependence is found. (orig.)

    Full Text Available The influence of equal channel angular pressing on the tension–compression yield asymmetry of extruded Mg–5.3 Zn–0.6 Ca (weight percent alloy has been investigated. The microstructure was obviously refined by the large strain during the equal channel angular pressing, accompanied with very fine Ca2Mg6Zn3 phases with average diameter of 70 nm. The weak tension–compression yield asymmetry after equal channel angular pressing is mainly attributed to the reduced volume fraction of extension twinning during the compression, because the slope (k of twinning in Hall–Petch relationship is higher than that of dislocation slip, and the twinning deformation is difficult to take place with decreasing grain size. The basal slip is more active in the alloy after equal channel angular pressing, due to the non-basal texture components, which hinders the twinning activation and reduces the yield asymmetry. Furthermore, the presence of fine precipitate restricts the twinning activation, which also contributes to the reduction of yield asymmetry.

    The sagittae mass asymmetry was studied in the teleost Carangoides caeruleopinnatus. The value of the asymmetry was calculated as the difference between the mass of the right and left paired otoliths, divided by average otolith mass. The results show that the absolute value of X in C. caeruleopinnatus does not depend on fish length and otolith growth rate, as it does in other symmetrical fish species. However, the absolute value of otolith mass difference increases with the fish length. The v...

  16. Strategies for precision measurements of the charge asymmetry of the W boson mass at the LHC within the ATLAS experiment

    CERN Document Server

    Fayette, Florent

    This thesis dissertation presents a prospect for a measurement of the charge asymmetry of the W boson mass (MW+ - MW-) at the LHC within the ATLAS experiment. This measurement is of primordial importance for the LHC experimental program, both as a direct test of the charge sign independent coupling of the W bosons to the fermions and as a mandatory preliminary step towards the precision measurement of the charge averaged W boson mass. This last pragmatic point can be understood since the LHC specific collisions will provide unprecedented kinematics for the positive and negative channels while the SPS and Tevatron collider produced W+ and W- on the same footing. For that reason, the study of the asymmetries between W+ and W- in Drell--Yan like processes (production of single W decaying into leptons), studied to extract the properties of the W boson, is described thoroughly in this document. Then, the prospect for a measurement of MW+ - MW- at the LHC is addressed in a perspective intending to decrease as much ...

    Full Text Available Excitation functions for sixteen evaporation residues produced in the interaction of 20Ne with 165Ho have been measured in the projectile energy range ≈88-164 MeV, using catcher foil activation technique followed by gamma-ray spectrometry. It has been found in general that the excitation functions of evaporation residues produced via xn/pxn channels satisfactorily reproduced with the statistical model code PACE-2 after subtraction of precursor decay contribution. The significant enhancement in the measured excitation functions for the residues produced in alpha emission channels over the PACE-2 predictions has been observed. These alpha emission channels are attributed to incomplete fusion reaction process. The results indicate the occurrence of incomplete fusion involving break-up of projectile 20Ne into 4He + 16O and /or 8Be + 12C followed by fusion of one of the fragments with target nucleus 165Ho. The analysis of the present data suggest that probability of incomplete fusion increases with projectile energy. The ICF fraction FICF also increases with increasing mass-asymmetry of the entrance channel.

    2014-01-01

    In this work, we try to explain the neutrino mass and mixing data radiatively at three-loop by extending the standard model (SM) with two charged singlet scalars and three right handed (RH) neutrinos. Here, the lightest RH neutrino is a dark matter candidate that gives a relic density in agreement with the recent Planck data, the model can be consistent with the neutrino oscillation data, lepton flavor violating processes, the electroweak phase transition can be strongly first order; and the charged scalars may enhance the branching ratio $h\\rightarrow\\gamma\\gamma$, where as $h\\rightarrow\\gamma Z$ get can get few percent suppression. We also discuss the phenomenological implications of the RH neutrinos at the collider.

    2016-01-01

    This paper describes an approach to identify epicyclic and tricyclic motion during projectile flight caused by mass asymmetries in spin-stabilized projectiles. Flight video was captured following projectile launch of several M110A2E1 155 mm artillery projectiles. These videos were then analyzed using the automated flight video analysis method to attain their initial position and orientation histories. Examination of the pitch and yaw histories clearly indicates that in addition to epicyclic motion’s nutation and precession oscillations, an even faster wobble amplitude is present during each spin revolution, even though some of the amplitudes of the oscillation are smaller than 0.02 degree. The results are compared to a sequence of shots where little appreciable mass asymmetries were present, and only nutation and precession frequencies are predominantly apparent in the motion history results. Magnitudes of the wobble motion are estimated and compared to product of inertia measurements of the asymmetric projectiles.

    We present radial velocity analysis for 20 solar neighborhood RR Lyrae and 3 Population II Cepheids. High-resolution spectra were observed with either TNG/SARG or VLT/UVES over varying phases. To estimate the center of mass (barycentric) velocities of the program stars, we utilized two independent methods. First, the 'classic' method was employed, which is based on RR Lyrae radial velocity curve templates. Second, we provide the new method that used absorption line profile asymmetry to determine both the pulsation and the barycentric velocities even with a low number of high-resolution spectra and in cases where the phase of the observations is uncertain. This new method is based on a least squares deconvolution (LSD) of the line profiles in order to an- alyze line asymmetry that occurs in the spectra of pulsating stars. By applying this method to our sample stars we attain accurate measurements (+- 2 kms^-1) of the pulsation component of the radial velocity. This results in determination of the barycentric velocity to within 5 kms^-1 even with a low number of high- resolution spectra.

    We present radial velocity analysis for 20 solar neighborhood RR Lyrae and 3 Population II Cepheids. High-resolution spectra were observed with either TNG/SARG or VLT/UVES over varying phases. To estimate the center of mass (barycentric) velocities of the program stars, we utilized two independent methods. First, the 'classic' method was employed, which is based on RR Lyrae radial velocity curve templates. Second, we provide the new method that used absorption line profile asymmetry to determine both the pulsation and the barycentric velocities even with a low number of high-resolution spectra and in cases where the phase of the observations is uncertain. This new method is based on a Least Squares Deconvolution (LSD) of the line profiles in order to analyze line asymmetry that occurs in the spectra of pulsating stars. By applying this method to our sample stars we attain accurate measurements (± 1 km/s) of the pulsation component of the radial velocity. This results in determination of the barycentric velocity to within 5 km/s even with a low number of high-resolution spectra. A detailed investigation of LSD profile asymmetry shows the variable nature of the project factor at different pulsation phases, which should be taken into account in the detailed spectroscopic analysis of pulsating stars.

  5. New measurements of the antineutrino-spin asymmetry in beta decay of the neutron and restrictions on the mass of a right-handed gauge boson

    International Nuclear Information System (INIS)

    The results of new measurements of the neutron antineutrino spin asymmetry coefficient B in the beta decay of polarized neutrons are considered. The measurements were carried out on the polarized neutron vertical channel of the WWR-M-Gatchina reactor. Basing on the combination of the results of measurements of the observed asymmetry P · B 0.6617 ± 0.0044 with those of the measurements on the neutron beam polarization P = (66.88 ± 0.22)% the value B = 0.9894 ± 0.0083 is obtained. This value implies that the mass of a hypothetical right-handed charged gauge boson in the left-right symmetric model of the weak interaction is greater than 281 GeV/c2 (90% CL). The conclusion on the agreement of this value with restrictions from muon decay and direct searches for an additional vector boson W is made. 9 refs., 1 tab., 5 figs

    The discovery in the last few years of the $X, Y$ and $Z$ states of the extended charmonium family has highlighted the importance of the closeness of decay channels to an understanding of these mesons. We aid this debate by illustrating a simple calculational procedure for including the effect of open and nearby closed channels.

    Full Text Available The sagittae mass asymmetry was studied in the teleost Carangoides caeruleopinnatus. The value of the asymmetry was calculated as the difference between the mass of the right and left paired otoliths, divided by average otolith mass. The results show that the absolute value of X in C. caeruleopinnatus does not depend on fish length and otolith growth rate, as it does in other symmetrical fish species. However, the absolute value of otolith mass difference increases with the fish length. The value of x falls between -0.2 and +0.2.

    Examination of the pitch and yaw histories clearly indicates that in addition to epicyclic motion's nutation and precession oscillations, an even faster wobble amplitude is present during each spin revolution, even though some of the amplitudes of the oscillation are smaller than 0.02 degree. The results are compared to a sequence of shots where little appreciable mass asymmetries were present, and only nutation and precession frequencies are predominantly apparent in the motion history results. Magnitudes of the wobble motion are estimated and compared to product of inertia measurements of the asymmetric projectiles.

    We discuss a TeV scale model which would explain neutrino oscillation, dark matter, and baryon asymmetry of the Universe simultaneously by the dynamics of the extended Higgs sector and TeV-scale right-handed neutrinos with imposed an exact $Z_2$ symmetry. Tiny neutrino masses are generated at the three loop level, a singlet scalar field is a candidate of dark matter, and a strong first order phase transition is realized for successful electroweak baryogenesis. The model provides various discr...

  10. High mass asymmetry in spontaneous and induced desintegration of heavy nuclei

    International Nuclear Information System (INIS)

    The experimental and theoretical results related to a new rupture mode of heavy ions (A>230) in mass fragments more different than ordinary ission products, are presented and disussed. Experiences of long exposure time by nuclear emulsion technique, show that, the U238 is also a spontaneous emitter of ions with mass number between 20 and 70. The results are interpreted as a high mass asymmetry in fission process or as a nucleon cluster emission mechanism by potential barrier penetration. Preliminary estimation show good agreement with experimental results for U238. Glass laminas with uranium thin films prepared 16 years ago, are also analysed aiming to confirm these results. Several experiences with nuclear emulsions and mica sandwich, and radiochemical data show to be possible heavy ion emission from U238 induced by photons of low energy as well as neutrons of reactor (M.C.K.)

  11. Dependence of deep-inelastic processes on entrance channel asymmetry and excitation energy. [506 to 732 MeV, angular distribution

    Energy Technology Data Exchange (ETDEWEB)

    Schmitt, R.P.

    1978-05-01

    The dependence of deep-inelastic processes on entrance channel asymmetry and on excitation energy was investigated. Thin targets of /sup nat/At, /sup 159/Tb, /sup 181/Ta and /sup 197/Au were bombarded with 620 MeV /sup 86/Kr ions. Additional measurements were performed on the reactions /sup nat/Ag + /sup 86/Kr and /sup 197/Au + /sup 86/Kr at 506 and 732 MeV incident energy. The energy spectra, the charge distributions and the angular distributions of these fragments were measured. At 620 MeV the energy spectra show that the distinction between quasi-elastic and deep-inelastic processes diminishes as the target mass is increased. The charge distributions, which are peaked at symmetry for /sup nat/Ag, tend to become increasingly asymmetric for the heavier systems. Likewise, the angular distributions exhibit a strong dependence on the entrance channel asymmetry. For the lightest system, /sup nat/Ag + /sup 86/Kr, the angular distributions are essentially forward peaked, aside from a separable quasi-elastic component. For the heaviest system, /sup 197/Au + /sup 86/Kr, the angular distributions are side-peaked. The transition between these two regimes occurs smoothly with increasing target mass. The results at 506 and 732 MeV show that the widths of the charge distributions are strongly dependent on the excitation energy. The angular distributions for the reaction /sup nat/Ag + /sup 86/Kr become increasingly more forward peaked at higher bombarding energies. The angular distributions for /sup 197/Au + /sup 86/Kr, which are strongly focused at 506 MeV, also tend to be more forward peaked at the highest incident energy. The results are interpreted by assuming that the projectile and target form an intermediate complex and that they exchange mass via a diffusion process. Because of the systematic nature of this study, the data should serve as a guide in the development of models of deep-inelastic processes.

  12. Mass asymmetry of fusion and fission processes induced in heavy ion reaction

    International Nuclear Information System (INIS)

    Simple parametrisations of nuclear shapes able to describe the essential features of the fission and fusion processes were introduced. The Myers-Swiatecki (1967) liquid drop model and its generalisations: the Krape-Nix (1974) finite range of nuclear forces model and the Krappe-Nix-Sierk (1979) folded Yukawa-plus-exponential model, were extended for the nuclear systems with different charge densities. Some information concerning the interaction barrier (Esub(I)) the energy release (Q) and the fission barrier (Esub(b)) trends of variation with mass and charge asymmetry were obtained from the energy at infinite separation distance between ions (or fission fragments), at the touching point and at the fused spherical system. Good agreement with experimental data was obtained and an empirical relationship for the estimation of the interaction barriers was derived. The reaction parteners, for which it is important to take into account the charge density difference, were identified and the orders of magnitude of the errors on Esub(I), Q and Esub(b) made if this difference is ignored, were estimated. The nonaxiality of the nuclear shape at the first saddle point was demonstrated on a simple model allowing to decrease the computer running time by 3 orders of magnitude. The asymmetric spheroidal oscillator, introduced by the author, can be used to study the fission process. The fission theory was successfully applied to compute the Q-values and the life-times of the alpha decay. Good agreement (within +-0.8 orders of magnitude) of the theoretical half-lives with experimental ones, over a range of 24 orders of magnitude was obtained. This is a strong argument that the alpha decay could be considered a fission process with very high mass asymmetry and charge density asymmetry. (author)

  13. The east-west asymmetry in Coronal Mass Ejections: evidence for active longitudes

    Directory of Open Access Journals (Sweden)

    M. Skirgiello

    2005-11-01

    Full Text Available Various manifestations of solar activity are not uniformly distributed with heliographic longitude. By using east-west asymmetry in the occurrence rate of CMEs (coronal mass ejections, the longitudinal dependence in SOHO LASCO 1996-2004 data has been studied in this work. The solar rotation periodicity has been found, indicating the presence of active longitudes, whose phase is reversed twice during the studied period. It is more prominent in the Southern Hemisphere. The east-west asymmetry is also present when calculated for longer time periods. Sometimes (particularly during low solar activity, there is an alternation of the eastern and western domination every six months. Taking into account the orbital revolution of the Earth about the Sun, this indicates the existence of enhanced activity, fixed in space (not undergoing Carrington rotation. Moreover, there is about a 3.7% overall excess of western events, lasting for the entire reported time, suggesting some bias in the observations. A hypothesis to explain this phenomenon is proposed.

    We present a measurement of forward-backward asymmetries in top-antitop quark pairs produced in proton-antiproton collisions decaying via the lepton+jets channel. Using data recorded by the D0 experiment at the Fermilab Tevatron collider and corresponding to an integrated luminosity of 5.4 fb-1, we measure the forward-backward asymmetry in top-antitop quark events to be $\\left(9.2 \\pm 3.7\\right)\\%$, after background processes have been subtracted. After correcting for the effects of acceptance and detector reconstruction, we measure an asymmetry of $\\left(19.6 \\pm 6.5\\right)\\%$. In addition, we measure an acceptance-corrected asymmetry based on the lepton from top-antitop quark decay of $\\left(15.2 \\pm 4.0\\right)\\%$. We compare these results to predictions from the MC@NLO next-to-leading-order QCD simulation.

    We measure the particle-level forward-backward production asymmetry in $b\\bar{b}$ pairs with masses $m(b\\bar{b})$ larger than 150 GeV/$c^2$, using events with hadronic jets and employing jet charge to distinguish $b$ from $\\bar{b}$. The measurement uses 9.5/fb of ppbar collisions at a center of mass energy of 1.96 TeV recorded by the CDF II detector. The asymmetry as a function of $m(b\\bar{b})$ is consistent with zero, as well as with the predictions of the standard model. The measurement disfavors a simple model including an axigluon with a mass of 200 GeV/$c^2$ whereas a model containing a heavier 345 GeV/$c^2$ axigluon is not excluded.

    We present a measurement of the top quark mass in the dilepton channel based on approximately 370/pb of data collected by the D0 experiment during Run II of the Fermilab Tevatron collider. We employ two different methods to extract the top quark mass. We show that both methods yield consistent results using ensemble tests of events generated with the D0 Monte Carlo simulation. We combine the results from the two methods to obtain a top quark mass m_t = 178.1 +/- 8.2 GeV. The statistical uncertainty is 6.7 GeV and the systematic uncertainty is 4.8 GeV.

    2012-02-01

    We aim to understand the role of Coulomb interactions as well as different equations of state on the disappearance of transverse flow for various asymmetric reactions leading to the same total mass. For the present study, the total mass of the system is kept constant (A_{\\text{TOT}} = 152) and mass asymmetry of the reaction is varied between 0.2 and 0.7. The Coulomb interactions as well as different equations of state are found to affect the balance energy significantly for larger asymmetric reactions.

    We propose an extended version of the standard model, in which neutrino oscillation, dark matter, and the baryon asymmetry of the Universe can be simultaneously explained by the TeV-scale physics without assuming a large hierarchy among the mass scales. Tiny neutrino masses are generated at the three-loop level due to the exact Z2 symmetry, by which the stability of the dark matter candidate is guaranteed. The extra Higgs doublet is required not only for the tiny neutrino masses but also for successful electroweak baryogenesis. The model provides discriminative predictions especially in Higgs phenomenology, so that it is testable at current and future collider experiments. PMID:19257506

    We discuss the discrimination of the 125 GeV spin-parity 0{sup +} Higgs-like boson observed at the LHC, decaying into two photons, H → γγ, against the hypothesis of a minimally coupled J{sup P} = 2{sup +} narrow diphoton resonance with the same mass and giving the same total number of signal events under the peak. We apply, as the basic observable of the analysis, the center.edge asymmetry ACE of the cosine of the polar angle of the produced photons in the diphoton rest frame to distinguish between the tested spin hypotheses. We show that the center.edge asymmetry A{sub CE} should provide a strong discrimination between the possibilities of spin-0 and spin-2 with graviton-like couplings, depending on the fraction of q anti q production of the spin-2 signal, reaching CL{sub s} < 10{sup -6} for f{sub qq} = 0. Indeed, the A{sub CE} has the potential to do better than existing analyses for f{sub qq} < 0.4. (orig.)

    In light of the latest neutrino oscillation data, we revisit the minimal scenario of type-I seesaw model, in which only two heavy right-handed Majorana neutrinos are introduced to account for both tiny neutrino masses and the baryon number asymmetry in our Universe. In this framework, we carry out a systematic study of the Frampton-Glashow-Yanagida ansatz by taking into account the renormalization-group running of neutrino mixing parameters and the flavor effects in leptogenesis.

  4. Compound nucleus decay along the mass asymmetry coordinate and the role of the Businaro-Gallone point

    International Nuclear Information System (INIS)

    The sharp distinction between evaporation and fission in relatively heavy compound nuclei is a result of a specific topological feature of the liquid drop model potential energy surface V(Z) as a function of mass asymmetry Z. This feature is a deep minimum at symmetry (fission region) flanked at greater asymmetries by the Businaro-Gallone mountains which in turn descend at even larger asymmetries (evaporation region). The experimental cross sections for 530-MeV 74Ge, 782-MeV 93Nb and 1157-MeV 139La + 9Be systems are shown. The cross sections are plotted as a function of charge asymmetry (Z/sub asy/ = Z/sub detected//Z/sub total/). The lack of enhancement in yield near the target Z supports the compound nucleus origin of the products rather than a deep-inelastic origin. The yield from the 74Ge + 9Be system, with a fissility parameter of x = 0.31, decreases steadily as one moves towards symmetry. The yields from the 93Nb + 9Be system (x = 0.40) are essentially constant from Z/sub asy/ = 0.2 to 0.4 while the yields from the 139La + 9Be system (x = 0.50) show the characteristic fission peak at symmetry. These three systems clearly exhibit the qualitative trends expected from the topological changes in the potential energy surface predicted by the liquid drop model

    Mass distribution for the two-photon channel. The strongest evidence for this new particle comes from analysis of events containing two photons. The smooth dotted line traces the measured background from known processes. The solid line traces a statistical fit to the signal plus background. The new particle appears as the excess around 126.5 GeV. The full analysis concludes that the probability of such a peak is three chances in a million.

    Mass distribution for the four-lepton channel. The search with the purest expected signal is done by examining events with two Z bosons that have decayed to pairs of electrons or muons. In the region from 120 to 130 GeV, 13 events are seen where only 5.3 were expected. The complete analysis concludes that the probability of such an excess would be three times in ten thousand if there were no new particle.

  10. Mass asymmetry dependence of fusion time-scales in 11B+237Np and 12C, 16O, 19F+232Th reactions in a dynamical trajectory model

    International Nuclear Information System (INIS)

    Dynamical trajectory calculations were carried out for the reactions of 11B+237Np and 12C, 16O and 19F+232Th, having mass asymmetries on either side of the Businaro-Gallone critical mass asymmetry αBG, in order to examine the mass asymmetry dependence of fusion reactions in these systems. The compound nucleus formation times were calculated as a function of the partial wave of the reaction for all the systems. This study brings out that for systems with αBG, the formation times are significantly larger than for α>αBG, which is caused by the dynamical effects involved in the large scale shape changes taking place in the fusion process as well as due to the interplay between the thermal and the collective motion during the collision process. The calculated time scales are comparable to the experimental values derived from the pre-fission neutron multiplicity measurements. (author). 16 refs., 4 figs., 1 tab

    Transitional discs are a class of circumstellar discs around young stars with extensive clearing of dusty material within their inner regions on 10s of au scales. One of the primary candidates for this kind of clearing is the formation of planet(s) within the disc that then accrete or clear their immediate area as they migrate through the disc. Our sample included eight transitional discs. Using the Keck/NIRC2 instrument we utilised the Sparse Aperture Masking (SAM) interferometry technique to search for asymmetries indicative of ongoing planet formation. We searched for close-in companions using both model fitting and interferometric image reconstruction techniques. Using simulated data, we derived diagnostics that helped us to distinguish between point sources and extended asymmetric disc emission. In addition, we investigated the degeneracy between the contrast and separation that appear for marginally resolved companions. We found FP Tau to contain a previously unseen disc wall, and DM Tau, LkHa 330, and ...

    2016-01-01

    We discuss the neutrino mass matrix based on the Occam's Razor approach in the framework of the seesaw mechanism. We impose four zeros in the Dirac neutrino mass matrix, which give the minimum number of parameters needed for the observed neutrino masses and lepton mixing angles, while the charged lepton mass matrix and the right-handed Majorana neutrino mass matrix are taken to be real diagonal ones. The low-energy neutrino mass matrix has only seven physical parameters. We show successful predictions for the mixing angle $\\theta_{13}$ and the CP violating phase $\\delta_{CP}$ with the normal mass hierarchy of neutrinos by using the experimental data on the neutrino mass differences, the mixing angles $\\theta_{12}$ and $\\theta_{23}$. The most favored region of $\\sin\\theta_{13}$ is around $0.13\\sim 0.15$, which is completely consistent with the observed value. The CP violating phase $\\delta_{CP}$ is favored to be close to $\\pm \\pi/2$. We also discuss the Majorana phases as well as the effective neutrino mass fo...

    Using the improved scission-point model, the mass distributions are calculated for induced fission of several Po and Ir isotopes. The calculated mass distributions and mean total kinetic energies of fission fragments are compared with the existing experimental data. The revealed coexistence of both symmetric and asymmetric modes in the β -delayed fission of At,196194 is in agreement with the experimental observations. The change of the shape of mass distribution with increasing A of fissioning AIr nucleus from asymmetric for 185Ir to symmetric for 193Ir is found.

  14. Shell and pairing effects in spontaneous fission for a wide range of mass asymmetries

    International Nuclear Information System (INIS)

    The following main contributions are emphasized. Calculations of symmetrical cold fission barriers by using the macroscopic Yukawa-plus-Exponential Model and parametrization of the nuclear shapes of two intersected spheres. A second (shallow) minimum occurs in a certain region of heavy nuclei. The introduction of a correction term takes into account the shell and pairing effects in the calculation of half lives against cluster emission within the analytical superasymmetric fission model. In this way we gave more realistic predictions. The resulting tables, referring to emission of heavy ions, alpha decay and cold fission, served as a guide for experimenters. The emission of 14 C, 20 O, 23 F, 24-26 Ne, 28,30 Mg, 32,34 Si from some Fr, Ra, Ac, Th, Pa, U, Pu, Cm isotopes covering a half live range of 15 orders of magnitude (1011-1026 s) have been already confirmed and are in good agreement with our predictions. By considering that the cold fission process is a cluster emission phenomenon, we have been able to reproduce numerically the most probable fragments experimentally determined in two regions of parent nuclei: U, Np, Pu, Cm, and Fm, Md, No. The transition from asymmetry to symmetry for the heavy Fm isotopes has also been fairly well reproduced. It was shown that even some 'stable' nuclei and neutron-rich non alpha-emitters are metastable against cluster emission. A new island of proton-rich cluster emission leading to daughter nuclei in the neighbourhood of 100 Sn has been predicted. Preliminary measurements recently performed in JINR-Dubna and GSI-Darmstadt have confirmed the 12 C radioactivity of 114 Ba. (Author) 38 Figs., 4 Tabs., 123 Refs

    To understand the nature of supernovae and neutron star (NS) formation, as well as binary stellar evolution and their interactions, it is important to probe the distribution of NS masses. Until now, all double NS (DNS) systems have been measured to have a mass ratio close to unity (q $\\geq$ 0.91). Here we report the measurement of the individual masses of the 4.07-day binary pulsar J0453+1559 from measurements of the rate of advance of periastron and Shapiro delay: The mass of the pulsar is 1.559(5) $M_{\\odot}$ and that of its companion is 1.174(4) $M_{\\odot}$; q = 0.75. If this companion is also a neutron star (NS), as indicated by the orbital eccentricity of the system (e=0.11), then its mass is the smallest precisely measured for any such object. The pulsar has a spin period of 45.7 ms and a spin derivative of 1.8616(7) x$10^-19$; from these we derive a characteristic age of ~ 4.1 x $10^9$ years and a magnetic field of ~ 2.9 x $10^9$ G,i.e, this pulsar was mildly recycled by accretion of matter from the pr...

    We present a measurement of the forward–backward asymmetry in top quark–antiquark production using the full Tevatron Run II data set collected by the D0 experiment at Fermilab. The measurement is performed in lepton+jets final states using a new kinematic fitting algorithm for events with four or more jets and a new partial reconstruction algorithm for events with only three jets. Corrected for detector acceptance and resolution effects, the asymmetry is evaluated to be AFB=(10.6±3.0)%. Results are consistent with the standard model predictions which range from 5.0% to 8.8%. We also present the dependence of the asymmetry on the invariant mass of the top quark–antiquark system and the difference in rapidities of the top quark and antiquark.

    Correlation functions and transport coefficients of self-diffusion and shear viscosity of a binary Lennard-Jones mixture with components differing only in their particle mass are studied up to high values of the mass ratio mu, including the limiting case mu = infinity, for different mole fractions x. Within a large range of x and mu the product of the diffusion coefficient of the heavy species D(2) and the total shear viscosity of the mixture eta(m) is found to remain constant, obeying a generalized Stokes-Einstein relation. At high liquid density, large mass ratios lead to a pronounced cage effect that is observable in the mean square displacement, the velocity autocorrelation function, and the van Hove correlation function.

  20. Forward–backward asymmetry of Drell–Yan lepton pairs in pp collisions at √(s)=7 TeV

    International Nuclear Information System (INIS)

    A measurement of the forward–backward asymmetry (AFB) of Drell–Yan lepton pairs in pp collisions at √(s)=7 TeV is presented. The data sample, collected with the CMS detector, corresponds to an integrated luminosity of 5 fb−1. The asymmetry is measured as a function of dilepton mass and rapidity in the dielectron and dimuon channels. Combined results from the two channels are presented, and are compared with the standard model predictions. The AFB measurement in the dimuon channel and the combination of the two channels are the first such results obtained at a hadron collider. The measured asymmetries are consistent with the standard model predictions.

    2015-01-01

    The late time optical and near-IR line profiles of many core-collapse supernovae exhibit a red-blue asymmetry as a result of greater extinction by internal dust of radiation emitted from the receding parts of the supernova ejecta. We present here a new code, DAMOCLES, that models the effects of dust on the line profiles of core-collapse supernovae in order to determine the masses of newly formed dust. As noted by Lucy et al. (1989), the presence of an extended red scattering wing in late-time line profiles can also indicate dust formation. We find that dust-affected line profiles need not necessarily be flux-biased towards to the blue, although the profile peak will always be blue-shifted. We have collated optical spectra of SN 1987A from a variety of archival sources and have modelled the evolution of the H$\\alpha$ line from days 714 to 3604, as well as that of the [OI] 6300,6363A doublet between days 714 and 1478. A variety of evidence points to the presence of clumping and we find that our clumped dust mod...

    2008-09-01

    The authors present the first measurement of the top quark mass using simultaneously data from two decay channels. They use a data sample of {radical}s = 1.96 TeV collisions with integrated luminosity of 1.9 fb{sup -1} collected by the CDF II detector. They select dilepton and lepton + jets channel decays of t{bar t} pairs and reconstruct two observables in each topology. They use non-parametric techniques to derive probability density functions from simulated signal and background samples. The observables are the reconstructed top quark mass and the scalar sum of transverse energy of the event in the dilepton topology and the reconstructed top quark mass and the invariant mass of jets from the W boson decay in lepton + jets channel. They perform a simultaneous fit for the top quark mass and the jet energy scale which is constrained in situ by the hadronic W boson resonance from the lepton + jets channel. Using 144 dilepton candidate events and 332 lepton + jets candidate events they measure: M{sub top} = 171.9 {+-} 1.7 (stat. + JES) {+-} 1.1 (other sys.) GeV/c{sup 2} = 171.9 {+-} 2.0 GeV/c{sup 2}. The measurement features a robust treatment of the systematic uncertainties, correlated between the two channels and develops techniques for a future top quark mass measurement simultaneously in all decay channels. Measurements of the W boson mass and the top quark mass provide a constraint on the mass of the yet unobserved Higgs boson. The Higgs boson mass implied by measurement presented here is higher than Higgs boson mass implied by previously published, most precise CDF measurements of the top quark mass in lepton + jets and dilepton channels separately.

    We report a measurement of the forward-backward asymmetry, $A_{FB}$, in $b\\bar{b}$ pairs produced in proton-antiproton collisions and identified by muons from semileptonic $b$-hadron decays. The event sample was collected at a center-of-mass energy of $\\sqrt{s}=1.96$ TeV with the CDF II detector and corresponds to 6.9 fb$^{-1}$ of integrated luminosity. We obtain an integrated asymmetry of $A_{FB}(b\\bar{b})=(1.2 \\pm 0.7)$\\% at the particle level for $b$-quark pairs with invariant mass, $m_{b\\bar{b}}$, down to $40$ GeV/$c^2$ and measure the dependence of $A_{FB}(b\\bar{b})$ on $m_{b\\bar{b}}$. The results are compatible with expectations from the standard model.

    We report a measurement of the forward-backward asymmetry, $A_{FB}$, in $b\\bar{b}$ pairs produced in proton-antiproton collisions and identified by muons from semileptonic $b$-hadron decays. The event sample was collected at a center-of-mass energy of $\\sqrt{s}=1.96$ TeV with the CDF II detector and corresponds to 6.9 fb$^{-1}$ of integrated luminosity. We obtain an integrated asymmetry of $A_{FB}(b\\bar{b})=(1.2 \\pm 0.7)$\\% at the particle level for $b$-quark pairs with invariant mass, $m_{b\\bar{b}}$, down to $40$ GeV/$c^2$ and measure the dependence of $A_{FB}(b\\bar{b})$ on $m_{b\\bar{b}}$. The results are compatible with expectations from the standard model.

    New techniques in cross-layer wireless networks are building demand for ubiquitous channel sounding, that is, the capability to measure channel impulse response (CIR) with any standard wireless network and node. Towards that goal, we present a software-defined IEEE 802.11b receiver and CIR estimation system with little additional computational complexity compared to 802.11b reception alone. The system implementation, using the universal software radio peripheral (USRP) and GNU Radio, is described and compared to previous work. By overcoming computational limitations and performing direct-sequence spread-spectrum (DS-SS) matched filtering on the USRP, we enable high-quality yet inexpensive CIR estimation. We validate the channel sounder and present a drive test campaign which measures hundreds of channels between WiFi access points and an in-vehicle receiver in urban and suburban areas.

  7. A Probabilistic Mass Estimation Algorithm for a Novel 7- Channel Capacitive Sample Verification Sensor

    2012-01-01

    A document describes an algorithm created to estimate the mass placed on a sample verification sensor (SVS) designed for lunar or planetary robotic sample return missions. A novel SVS measures the capacitance between a rigid bottom plate and an elastic top membrane in seven locations. As additional sample material (soil and/or small rocks) is placed on the top membrane, the deformation of the membrane increases the capacitance. The mass estimation algorithm addresses both the calibration of each SVS channel, and also addresses how to combine the capacitances read from each of the seven channels into a single mass estimate. The probabilistic approach combines the channels according to the variance observed during the training phase, and provides not only the mass estimate, but also a value for the certainty of the estimate. SVS capacitance data is collected for known masses under a wide variety of possible loading scenarios, though in all cases, the distribution of sample within the canister is expected to be approximately uniform. A capacitance-vs-mass curve is fitted to this data, and is subsequently used to determine the mass estimate for the single channel s capacitance reading during the measurement phase. This results in seven different mass estimates, one for each SVS channel. Moreover, the variance of the calibration data is used to place a Gaussian probability distribution function (pdf) around this mass estimate. To blend these seven estimates, the seven pdfs are combined into a single Gaussian distribution function, providing the final mean and variance of the estimate. This blending technique essentially takes the final estimate as an average of the estimates of the seven channels, weighted by the inverse of the channel s variance.

    Disposable plastic electrospray chips are particularly attractive for the automated analysis of organic compounds and organometallic compounds. Automated multi-track chip-based infusion electrospray mass spectrometry of low molecular weight compounds using an eight-channel plastic chip is presented. For that purpose, the commercial interface of a triple quadrupole linear ion trap was modified. A dual-channel plastic microchip, where two physically separated channels arrive very close to each other at the chip tip, was used to perform lock-mass accurate mass measurements on a quadrupole-time-of-flight instrument. The same chip was used to demonstrate the formation of an organometallic complex in solution on the chip tip. Furthermore, the potential to control the flow rate of each channel individually, which opens new possibilities in the study of supramolecular complexes, is discussed. PMID:20065514

    The top quark discovery completed the present picture of the fundamental constituents of the nature. Since then, the Collider Detector at Fermilab and D0 Collaborations have been spending great efforts to measure its properties better. About 30 times larger than the second heaviest quark, the mass of the top has been measured with increased statistic and more and more sophisticated techniques in order to reduce as much as possible its uncertainty. This is because the top is expected to play a fundamental role in the Standard Model. The value of its mass sets boundaries on the mass of the unobserved Higgs boson, and perhaps more appealing, studies of its properties might lead to the discovery of new physics.

    Transmission distortion of disease-causing alleles in long QT syndrome (LQTS) has been reported, suggesting a potential role of KCNQ1 and KCNH2 in reproduction. This study sought to investigate parental transmission in LQTS families according to ethnicity, gene loci (LQT1-3: KCNQ1, KCNH2, and SCN5A) or severity of channel dysfunction. We studied 3782 genotyped members from 679 European and Japanese LQTS families (2748 carriers). We determined grandparental and parental origins of variant alleles in 1903 children and 624 grandchildren, and the grandparental origin of normal alleles in healthy children from 44 three-generation control families. LQTS alleles were more of maternal than paternal origin (61 vs 39%, Pgrandmother alleles. For LQT1, maternal transmission differs according to the variant level of dysfunction with 68% of maternal transmission for dominant negative or unknown functional consequence variants vs 58% for non-dominant negative and variants leading to haploinsufficiency, P<0.01; however, for LQT2 or LQT3 this association was not significant. An excess of disease-causing alleles of maternal origin, most pronounced in LQT1, was consistently found across ethnic groups. This observation does not seem to be linked to an imbalance in transmission of the LQTS subtype-specific grandparental allele, but to the potential degree of potassium channel dysfunction.

    We analyze CP asymmetries of B to phi K_S and B to eta' K_S in a supersymmetric grand unified theory in which only third generation sfermions contained in 10(Q, U^c, E^c) of SU(5) can have a different mass from the others. One of advantages of this nonuniversal mass model is that the first two generation sfermion masses can be large whereas both (left and right handed) stops are light so as to stabilize the weak scale. Therefore we studied on minimal supersymmetric standard model parameter region in which a fine tuning in Higgs sector is relaxed due to light masses of stops, gluino and higgsinos. In such the parameter region, the chargino contribution is as important as gluino one. We show that the CP asymmetries of B to phi K_S and B to eta' K_S can deviate from their standard model predicted values by O(0.1) because of constructive interference between gluino and chargino contributions.

  13. Meet me on the other side: trans-bilayer modulation of a model voltage-gated ion channel activity by membrane electrostatics asymmetry.

    Loredana Mereuta

    Full Text Available While it is accepted that biomembrane asymmetry is generated by proteins and phospholipids distribution, little is known about how electric changes manifested in a monolayer influence functional properties of proteins localized on the opposite leaflet. Herein we used single-molecule electrophysiology and investigated how asymmetric changes in the electrostatics of an artificial lipid membrane monolayer, generated oppositely from where alamethicin--a model voltage-gated ion channel--was added, altered peptide activity. We found that phlorizin, a membrane dipole potential lowering amphiphile, augmented alamethicin activity and transport features, whereas the opposite occurred with RH-421, which enhances the monolayer dipole potential. Further, the monolayer surface potential was decreased via adsorption of sodium dodecyl sulfate, and demonstrated that vectorial modification of it also affected the alamethicin activity in a predictive manner. A new paradigm is suggested according to which asymmetric changes in the monolayer dipole and surface potential extend their effects spatially by altering the intramembrane potential, whose gradient is sensed by distantly located peptides.

  14. Enhanced stability of hillslopes and channel beds to mass failure

    The stability of inclined, unconsolidated sediments subjected to groundwater flow on hillslopes and steep channel beds is important for both landscape evolution and natural hazards. Force-balance models have been used for seven decades to predict the stability of slopes, but they generally underpredict the degree of saturation required to destabilize the sediment. Researchers often appeal to heightened stabilizing forces from root and mineral cohesion, and friction acting on the margins of the failure to explain this underprediction. Surprisingly, infinite-slope stability models in their simplest form have never been tested under controlled laboratory conditions. To address this gap in data, we perform a set of controlled laboratory experiments with slope-parallel seepage in the simplest possible configuration. We performed 47 experiments in a 5 m laboratory flume with 4 grain sizes (D50 = 0.7, 2, 5, and 15 mm) and a wide range in bed angles (20° to 43°), spanning both Darcian and turbulent subsurface flow regimes. Our experiments show that granular slopes were more stable than predicted by simple force balance models in experiments that lack root or mineral cohesion. Despite the smooth plastic walls and the long aspect ratio of our flume, we calculate wall and toe friction to be important. Including these additional resistance terms in the model reduces the model misfit with our experimental results. However, there is considerable remaining misfit (up to 50% underestimation of the saturation level required for failure). We investigate two explanations of this heightened stability: 1) standard frictional resistance terms are underestimated, and 2) seepage stresses are overestimated. Both explanations require that we modify the models used to predict slope stability.

  15. Measurements of W Charge Asymmetry

    We discuss W boson and lepton charge asymmetry measurements from W decays in the electron channel, which were made using 9.7 fb$^{-1}$ of RunII data collected by the D0 detector at the Fermilab Tevatron Collider. The electron charge asymmetry is presented as a function of pseudo-rapidity out to |$\\eta$| $\\le$ 3.2, in five symmetric and asymmetric kinematic bins of electron transverse momentum and the missing transverse energy of the event. We also give the W charge asymmetry as a function of W boson rapidity. The asymmetries are compared with next-to-leading order perturbative quantum chromodynamics calculations. These charge asymmetry measurements will allow more accurate determinations of the proton parton distribution functions and are the most precise to date.

  16. Transverse top quark polarization and the forward-backward asymmetry

    Baumgart, Matthew; Tweedie, Brock

    2013-08-01

    The forward-backward asymmetry in top pair production at the Tevatron has long been in tension with the Standard Model prediction. One of the only viable new physics scenarios capable of explaining this anomaly is an s-channel axigluon-like resonance, with the quantum numbers of the gluon but with significant axial couplings to quarks. While such a resonance can lead to a clear bump or excess in the or dijet mass spectra, it may also simply be too broad to cleanly observe. Here, we point out that broad resonances generally lead to net top and antitop polarizations transverse to the production plane. This polarization is consistent with all discrete spacetime symmetries, and, analogous to the forward-backward asymmetry itself, is absent in QCD at leading order. Within the parameter space consistent with the asymmetry measurements, the induced polarization can be sizable, and might be observable at the Tevatron or the LHC.

    Models of how mountain belts grow and erode through time largely rely on the paradigm of fluvial bedrock incision as the main motor of response to differences in rock uplift, thus setting base levels of erosion in tectonically active landscapes. Dynamic feedbacks between rock uplift, bedrock river geometry, and mass wasting have been encapsulated within the concept of threshold hillslopes that attain a mechanically critical inclination capable of adjusting to fluvial incision rates via decreased stability and commensurately more frequent landsliding. Here we provide data that challenge the widely held view that channel steepness records tectonic forcing more faithfully than hillslope inclination despite much robust empirical evidence of such links between bedrock-river geometry and hillslope mass wasting. We show that the volume mobilized by mass wasting depends more on local topographic relief and the sinuosity of bedrock rivers than their mean normalized channel steepness. We derive this counterintuitive observation from an unprecedented inventory of ~300,000 landslides covering the tectonically active Japanese archipelago with substantial differences in seismicity, lithology, vertical surface deformation, topography, and precipitation variability. Both total landslide number and volumes increase nonlinearly with mean local relief even in areas where the fraction of steepest channel segments attains a constant threshold well below the maximum topographic relief. Our data document for the first time that mass wasting increases systematically with preferential steepening of flatter channel segments. Yet concomitant changes in mean channel steepness are negligible such that it remains a largely insensitive predictor of landslide denudation. Further, minute increases in bedrock-river sinuosity lead to substantial reduction in landslide abundance and volumes. Our results underline that sinuosity (together with mean local relief) is a key morphometric variable for

    The D0 collaboration at FermiLab has recently measured the top-quark pair forward-backward asymmetry in $\\bar p p \\to t \\bar t X$ reactions as a function of the $\\bar t t $ invariant mass $M_{t\\bar{t}}$. D0 observed that the asymmetry $A_{\\rm FB}(M_{t\\bar{t}})$ first increases and then decreases as $M_{t\\bar{t}}$ is increased. This behavior is not explained using conventional renormalization scale-setting, even by a next-to-next-to-leading order (N$^2$LO) QCD calculation -- one predicts a monotonically increasing behavior. In the conventional scale-setting method, one simply guesses a single renormalization scale $\\mu_r$ for the argument of the QCD running coupling and then varies it over an arbitrary range. However, the conventional method has inherent difficulties. ...... In contrast, if one fixes the scale using the Principle of Maximum Conformality (PMC), the resulting pQCD predictions are renormalization-scheme independent since all of the scheme-dependent $\\{\\beta_i\\}$-terms in the QCD perturbative seri...

    Mavromatos, Nick E

    2015-01-01

    We discuss here a specific field-theory model, inspired from string theory, in which the generation of a matter-antimatter asymmetry in the Cosmos is due to the propagation of fermions in a non-trivial, spherically asymmetric (and hence Lorentz violating) gravitational background that may characterise the epochs of the early universe. The background induces different dispersion relations, hence populations, between fermions and antifermions, and thus CPT Violation (CPTV) already in thermal equilibrium. Species populations may freeze out leading to leptogenesis and baryogenesis. More specifically, after reviewing some generic models of background-induced CPTV in early epochs of the Universe, we consider a string-inspired scenario, in which the CPTV is associated with a cosmological background with torsion provided by the Kalb-Ramond (KR) antisymemtric tensor field of the string gravitational multiplet. In a four-dimensional space time this field is dual to a pseudoscalar ``axion-like'' field. The thermalising ...

    We report on a measurement of the mass dependence of the forward-backward charge asymmetry, A(FB), and production cross section d sigma/dM for e(+)e(-) pairs with mass M(ee)>40 GeV/c(2). The data sample consists of 108 pb(-1) of pp macro collisions at square root of s = 1.8 TeV taken by the Collider Detector at Fermilab during 1992-1995. The measured asymmetry and d sigma/dM are compared with the predictions of the standard model and a model with an extra Z' gauge boson. PMID:11580576

  1. Simultaneous Heat and Mass Transfer in Inclined Channel with Asymmetrical Conditions

    Full Text Available The present work is a numerical study of simultaneous heat and mass transfer with phase change in an inclined channel formed by two parallel plates. The lower one is covered by a thin liquid water film and the upper one is considered impermeable. The plates are maintained at a constant temperature. The liquid film is assumed to be extremely thin and its temperature is uniform and equal to that of the wall. Thermo-physical properties are considered constant and the Boussinesq assumption is adopted. Results show that the effects of the buoyancy forces on the hydrodynamic, thermal and mass fraction fields are important. These effects depend on the channel inclination and may result on flow reversal when the channel approaches the vertical position. This phenomenon is addressed and a flow reversal chart, as well as the corresponding correlations, for different channel inclinations is given. These correlations give the values of Grashof numbers, which induce flow reversal for a given Reynolds number and inclination angle.

    Human mutations in the cytoplasmic C-terminal domain of Slack sodium-activated potassium (KNa) channels result in childhood epilepsy with severe intellectual disability. Slack currents can be increased by pharmacological activators or by phosphorylation of a Slack C-terminal residue by protein kinase C. Using an optical biosensor assay, we find that Slack channel stimulation in neurons or transfected cells produces loss of mass near the plasma membrane. Slack mutants associated with intellectual disability fail to trigger any change in mass. The loss of mass results from the dissociation of the protein phosphatase 1 (PP1) targeting protein, Phactr-1, from the channel. Phactr1 dissociation is specific to wild-type Slack channels and is not observed when related potassium channels are stimulated. Our findings suggest that Slack channels are coupled to cytoplasmic signaling pathways and that dysregulation of this coupling may trigger the aberrant intellectual development associated with specific childhood epilepsies.

    2016-01-01

    We use a fixed-order expansion of resummed soft-gluon corrections to determine an approximate NNLO formula for the partonic cross section of single-top production in the $s$-channel. This formula is implemented in the program Hathor for the numerical evaluation of hadronic cross sections. With the resulting code, we perform a fit of the top-quark mass to Tevatron cross section data. Results for $m_t$ are given in the pole-mass scheme and in the $\\overline{\\mathrm{MS}}$ scheme.

  7. Improving knowledge of water-mass circulation in the English Channel using radioactive tracers

    International Nuclear Information System (INIS)

    New tools are now available to make more accurate determinations of radio-tracer distribution. Recent campaigns carried out during the FluxManche II CCE (1994) programme show the general distribution of dissolved radionuclides 137Cs, 134Cs, 125Sb and 3H in the English Channel and Irish Sea. The re-utilization of data from previous campaigns (1983, 1986 and 1988) provides indication, at any given location in the English Channel, about the average dilution and distribution of releases derived form the La Hague reprocessing plant. Excesses and losses of radionuclides are now quantified with respect to known source-terms; estimates of losses are provided for non-conservative radionuclides, while and excess of 137Cs was observed in the English Channel during the period 1983 - 1994. This excess would represent about 1% of Sellafield releases entering the Channel. These results confirm and give a more detailed picture of the previously known distribution of water masses in the English Channel. (author)

  8. CHARACTERIZING THE BROWN DWARF FORMATION CHANNELS FROM THE INITIAL MASS FUNCTION AND BINARY-STAR DYNAMICS

    International Nuclear Information System (INIS)

    The stellar initial mass function (IMF) is a key property of stellar populations. There is growing evidence that the classical star-formation mechanism by the direct cloud fragmentation process has difficulties reproducing the observed abundance and binary properties of brown dwarfs and very-low-mass stars. In particular, recent analytical derivations of the stellar IMF exhibit a deficit of brown dwarfs compared to observational data. Here we derive the residual mass function of brown dwarfs as an empirical measure of the brown dwarf deficiency in recent star-formation models with respect to observations and show that it is compatible with the substellar part of the Thies-Kroupa IMF and the mass function obtained by numerical simulations. We conclude that the existing models may be further improved by including a substellar correction term that accounts for additional formation channels like disk or filament fragmentation. The term ''peripheral fragmentation'' is introduced here for such additional formation channels. In addition, we present an updated analytical model of stellar and substellar binarity. The resulting binary fraction and the dynamically evolved companion mass-ratio distribution are in good agreement with observational data on stellar and very-low-mass binaries in the Galactic field, in clusters, and in dynamically unprocessed groups of stars if all stars form as binaries with stellar companions. Cautionary notes are given on the proper analysis of mass functions and the companion mass-ratio distribution and the interpretation of the results. The existence of accretion disks around young brown dwarfs does not imply that these form just like stars in direct fragmentation

  10. Measurement of the forward-backward asymmetry in the distribution of leptons in $t\\bar{t}$ events in the lepton$+$jets channel

    Abazov, Victor Mukhamedovich; et al.

    2014-10-07

    We present measurements of the forward-backward asymmetry in the angular distribution of leptons from decays of top quarks and antiquarks produced in proton-antiproton collisions. We consider the final state containing a lepton and at least three jets. The entire sample of data collected by the D0 experiment during Run II of the Fermilab Tevatron Collider, corresponding to 9.7 inverse fb of integrated luminosity, is used. The asymmetry measured for reconstructed leptons is $A_{FB}^l = \\big(2.9 \\pm 2.1(stat.) ^{+1.5}_{-1.7}(syst.) \\big)$%. When corrected for efficiency and resolution effects within the lepton rapidity coverage of $|y_l|<1.5$, the asymmetry is found to be $A_{FB}^l = \\big(4.2 \\pm 2.3(stat.) ^{+1.7}_{-2.0}(syst.) \\big)$%. Combination with the asymmetry measured in the dilepton final state yields $A_{FB}^l = \\big(4.2 \\pm 2.0(stat.) \\pm 1.4(syst.) \\big)$%. We examine the dependence of $A_{FB}^l$ on the transverse momentum and rapidity of the lepton. The results are in agreement with predictions from the next-to-leading-order QCD generator \\mcatnlo, which predicts an asymmetry of $A_{FB}^l = 2.0$% for $|y_l|<1.5$.

  11. Entrance channel effect and fusion cross sections in the synthesis of heavy and superheavy nuclei

    International Nuclear Information System (INIS)

    The entrance channel effect, mainly involved the mass asymmetry, the neutron-excess and the collision orientation of the combined system, are presented by summarizing the recent theoretical results about the fusion reactions leading to the same compound nuclei and the neutron-rich fusion reactions in the synthesis of heavy and superheavy nuclei through various models. It is concluded that the system with large mass asymmetry and neutron-rich nuclear reactions is favorable for the compound nucleus formation. (author)

    The incomplete fusion reactions is a dynamic area of investigation due to complex nature of incomplete mass transfer and its dependence on various entrance channel parameters like type of projectile, energy of projectile, transfer of input angular momentum (ℓ), deformations of the interacting nuclides, mass-asymmetry and α-break up energy (Qα). The aim of this work is to investigate the dependence of ICF on different entrance channel parameters

  13. Constraint of baryon asymmetry on grand unified theories and X-X/sup c/ mass splitting scenario for baryon number generation

    International Nuclear Information System (INIS)

    An important constraint on Grand Unified Theories (GUTs) is the correct estimate of Baryon Asymmetry of the Universe (BAU), in the standard scenario and with a conventional energy-temperature behavior. This is proportional to the intrinsic maximal CP-violation at superhigh energies, which as the lore goes barely accounts for the observed baryon-to-entropy ratio. This is further controlled by some global features: a global symmetry, if broken inadequately, can unduely suppress the estimate and the problem is how to overwhelm the suppression. Illustrated variously, this possibility of the group-theoretical constraint is also contrasted with that of a dynamical constraint. Attention is focused on a specific constraint, that arising from the broken group-C invariance (C = Charge-conjugation), note its implications on neutrino mass and examine, in particular, how to overwhelm the resulting suppression by splitting the mass of the decaying scalar X from its charge conjugate X/sup c/ in an SO(10) theory with Written's mechanism for neutrino mass. This possibility of X-X/sup c/ mass-splitting was envisaged in the previous general study (with Haber and Segre) whose important conclusions are reviewed: some general observations on spontaneously unbroken C-invariance and a solution to the problem of BAU, in spontaneously broken C-invariant theories, by allowing no overlap between the contributions form the free-decays of X-anti X and S/sup c/-anti X/sup c/ pairs through nu-N/sup c/ mass splitting greater than or equal to m (X). Only the following details are now added

  14. Baryon asymmetry in inflationary universe

    International Nuclear Information System (INIS)

    The problem of the baryon asymmetry in inflationary universe is discussed. It is shown that the baryon asymmetry in inflationary universe under certain constrainsts on masses of superheavy bosons can be larger than that in the standard scenario. An important property of the model considered is that the final baryon asymmetry does not depend on initial conditions in the early universe in contrast to what occUrs in the standard scenario based on (B-L) conserving grand unified theories. The new scenario is realized in the framework of the SU(5) Coleman-Weinberg theory with the symmetry breaking

  15. Top quark mass measurement in the dilepton channel in the D0 experiment at the Tevatron

    International Nuclear Information System (INIS)

    The top quark is the heaviest standard model quark. Discovered in 1995 by the two Tevatron experiments it has atypical properties. In particular its time life is so short that it decays before hadronizing, so the top quark mass could be measured with a high precision. Data collected by the D0 experiment between 2002 and 2009, which represent an integrated luminosity of 5.4 fb-1, are used to measure the top quark mass by using the matrix element method in the three dilepton channels: dielectron, electron-muon and dimuon. The measured mass, (174,0 ± 1,8 (stat.) ± 2,4 (syst.)) GeV, is in a good agreement with other measurements and limited by the systematic uncertainties for the first time in these channels. In this thesis different approaches have been studied to improve the accuracy of this measurement: the use of b-quark jet identification in order to optimize the selection of top - anti-top events and a better determination of the main systematic uncertainties. A special attention has been paid to the Monte-Carlo simulation of muons in D0: the improved smearing procedure for the simulated muons, discussed in this thesis, will be used to increase the accuracy of the top properties measurements as well as the precision of many other D0 measurements.

  16. An SO(10) × SO(10)' model for common origin of neutrino masses, ordinary and dark matter-antimatter asymmetries

    International Nuclear Information System (INIS)

    We propose an SO(10) × SO(10)' model to simultaneously realize a seesaw for Dirac neutrino masses and a leptogenesis for ordinary and dark matter-antimatter asymmetries. A (16 × 1-bar 6-bar ')H scalar crossing the SO(10) and SO(10)' sectors plays an essential role in this seesaw-leptogenesis scenario. As a result of lepton number conservation, the lightest dark nucleon as the dark matter particle should have a determined mass around 15 GeV to explain the comparable fractions of ordinary and dark matter in the present universe. The (16 × 1-bar 6-bar ')H scalar also mediates a U(1)em × U(1)'em kinetic mixing after the ordinary and dark left-right symmetry breaking so that we can expect a dark nucleon scattering in direct detection experiments and/or a dark nucleon decay in indirect detection experiments. Furthermore, we can impose a softly broken mirror symmetry to simplify the parameter choice

    The present investigation addresses the simultaneous effects of heat and mass transfer in the mixed convection peristaltic flow of viscous fluid in an asymmetric channel. The channel walls exhibit the convective boundary conditions. In addition, the effects due to Soret and Dufour are taken into consideration. Resulting problems are solved for the series solutions. Numerical values of heat and mass transfer rates are displayed and studied. Results indicate that the concentration and temperature of the fluid increase whereas the mass transfer rate at the wall decreases with increase of the mass transfer Biot number. Furthermore, it is observed that the temperature decreases with the increase of the heat transfer Biot number.

    Mathematical modeling suggests that relatively large values of otolith mass asymmetry in fishes can alter acoustic functionality and may be responsible for abnormal fish behavior when subjected to weightlessness during parabolic or space flight [D.V. Lychakov, Y.T. Rebane, Otolith mass asymmetry in 18 species of fish and pigeon, J. Grav. Physiol. 11 (3) (2004) 17-34; D.V. Lychakov, Y.T. Rebane, Fish otolith mass asymmetry: morphometry and influence on acoustic functionality, Hear. Res. 201 (2005) 55-69]. The results of morphometric studies of otolith mass asymmetry suppose that the absolute value and the sign of the otolith mass asymmetry can change many times during the growth of individual fish within the range +/-20% [D.V. Lychakov, Y.T. Rebane, Otolith mass asymmetry in 18 species of fish and pigeon, J. Grav. Physiol. 11 (3) (2004) 17-34; D.V. Lychakov, Y.T. Rebane, Fish otolith mass asymmetry: morphometry and influence on acoustic functionality, Hear. Res. 201 (2005) 55-69]. This implies that the adverse effects of otolith asymmetry on acoustic and vestibular functionality could change during the lifetime of an individual fish. The aims of the present article were to examine the nature of otolith mass asymmetry fluctuation and to quantify otolith mass asymmetry in a large number of teleost fishes to verify our previous measurements. A dimensionless measure of otolith mass asymmetry, chi, was calculated as the difference between the masses of the right and left paired otoliths divided by average otolith mass. Saccular otolith mass asymmetry was studied in 59 Mediterranean teleost species (395 otolith pairs), 14 Black Sea teleost species (42 otolith pairs), red drum (196 otolith pairs) and guppy (30 otolith pairs). Utricular otolith mass asymmetry was studied in carp (103 otolith pairs) and goldfish (45 otolith pairs). In accordance with our previous results the value of chi did not depend on fish size (length or mass), systematic or ecological position of the

In our analysis we discuss the opposite sign same flavor leptons signal, as well as the background free channel with the tau contribution which can enhance the signal/background ratio for center of mass energies $\\sqrt{s}$= 8 \\textrm{TeV} and $\\sqrt{s}$ = 14 \\textrm{TeV}.

    2014-12-11

    Multiphoton photoelectron circular dichroism (MP-PECD) has been observed as an asymmetry in the angular distribution of photoelectrons emitted in the ionization of pure enantiomers of the small chiral molecule methyloxirane using a femtosecond laser operated at 420 nm. Energetically, this requires the uptake of four photons. By switching the laser between left- and right-circular polarization, and observing the differences in the full three-dimensional electron momentum distribution recorded in an electron-ion coincidence technique, the chiral (odd) terms in the angular distribution expression can be isolated. Electron events can additionally be filtered by coincident ion mass, providing mass-tagged electron distributions and quantitative measures of the MP-PECD asymmetry that help characterize the different ionization channels. For the production of ground state parent cation, the magnitude of the mean chiral asymmetry is measured to be 4.7%, with a peak magnitude exceeding 10% PMID:25402546

    A measurement of the forward-backward asymmetry (A{sub FB}) of Drell-Yan lepton pairs in pp collisions at {radical}(s)=7 TeV is presented. The data sample, collected with the CMS detector, corresponds to an integrated luminosity of 5 fb{sup -1}. The asymmetry is measured as a function of dilepton mass and rapidity in the dielectron and dimuon channels. Combined results from the two channels are presented, and are compared with the standard model predictions. The A{sub FB} measurement in the dimuon channel and the combination of the two channels are the first such results obtained at a hadron collider. The measured asymmetries are consistent with the standard model predictions.

    Numerical calculations were conducted to simulate the flow and mass transfer in narrow membrane channels with and without flow disturbers. The channel consists of an impermeable solid wall and a membrane surface with a spacing of 2.0 mm. The flow disturbers studied include rectangular winglets, which are often used as lon-gitudinal vortex generators to enhance heat transfer in heat exchanger applications, as wel as square prism, tri-angular prism, and circular cylinder, which are used here to mimic the traditional spacer filaments for comparison of their abilities in enhancing the convective mass transfer near the membrane surface to al eviate the concentration polarization. The disturber performance was evaluated in terms of concentration polarization factor versus consumed pumping power, with a larger factor meaning a more serious concentration polarization. Calculations were carried out for NaCl solution flow with Reynolds numbers ranging from 400 to 1000. The results show that the traditional flow disturbers can considerably reduce the concentration polarization but cause a substantial pressure drop, while the rectangular winglets can effectively reduce the concentration polarization with a much less pressure drop penalty. The rectangular winglets were optimized in geometry under equal pumping power condition.

  3. Study on Methanol Conversion Efficiency and Mass Transfer of Steam-Methanol Reforming on Flow Rate Variation in Curved Channel

    International Nuclear Information System (INIS)

    In this study, numerical analysis of curved channel steam-methanol reformer was conducted using the computational fluid dynamics (CFD) commercial code STAR-CCM. A pre-numerical analysis of reference model with a cylindrical channel reactor was performed to validate the combustion model of the CFD commercial code. The result of advance validation was in agreement with reference model over 95%. After completing the validation, a curved channel reactor was designed to determine the effects of shape and length of flow path on methanol conversion efficiency and generation of hydrogen. Numerical analysis of the curved-channel reformer was conducted under various flow rate (10/15/20 μl/min). As a result, the characteristics of flow and mass transfer were confirmed in the cylindrical channel and curved channel reactor, and useful information about methanol conversion efficiency and hydrogen generation was obtained for various flow rate.

    The authors present a measurement of the mass of the top quark using data corresponding to an integrated luminosity of 1.9 fb{sup -1} of p{bar p} collisions collected at {radical}s = 1.96 TeV with the CDF II detector at Fermilab's Tevatron. This is the first measurement of the top quark mass using top-antitop pair candidate events in the lepton + jets and dilepton decay channels simultaneously. They reconstruct two observables in each channel and use a non-parametric kernel density estimation technique to derive two-dimensional probability density functions from simulated signal and background samples. The observables are the top quark mass and the invariant mass of two jets from the W decay in the lepton + jets channel, and the top quark mass and the scalar sum of transverse energy of the event in the diletpon channel. They perform a simultaneous fit for the top quark mass and the jet energy scale, which is constrained in situ by the hadronic W boson mass. using 332 lepton + jets candidate events and 144 diletpon candidate events, they measure the top quark mass to be m{sub top} = 171.9 {+-} 1.7 (stat. + JES) {+-} 1.1 (other sys.) GeV/c{sup 2} = 171.9 {+-} 2.0 GeV/c{sup 2}.

    Particle-laden flows in a horizontal channel were investigated by means of a two-phase particle image velocimetry (PIV) technique.Experiments were performed at a Reynolds number of 6826 and the flow is seeded with polythene beads of two sizes,60μm and 110μm.One was slightly smaller than and the other was larger than the Kolmogorov length scale.The particle loadings were relatively low,with mass loading ratio ranging from 5×10-4 to 4×10-2 and volume fractions from 6×10-7 to 4.8×10-5,respectively.The results show that the presence of particles can dramatically modify the turbulence even under the lowest mass loading ratio of 5×10-4.The mean flow is attenuated and decreased with increasing particle size and mass loading The turbulence intensities are enhanced in all the cases concerned.With the increase of the mass loading,the intensities vary in a complicated manner in the case of small particles,indicating complicated particle-turbulence interactions;whereas they increase monotonously in the case of large particles.The particle velocities and concentrations are also given.The particles lag behind the fluid in the center region but lead in the wall region,and this trend is more prominent for the large particles.The streamwise particle fluctuations are larger than the gas fluctuations for both sizes of particles,however their varying trend with the mass loadings is not so clear.The wallnormal fluctuations increase with increasing mass loadings.They are smaller in the 60μm particle case but larger in the 110μm particle case than those of the gas phase.It seems that the small particles follow the fluid motion to certain extent while the larger particles are more likely dominated by their own inertia.Finally,remarkable non-uniform distributions of particle concentration are observed,especially for the large particles.The inertia of particles is proved to be very important for the turbulence modification and particles behaviors and thus should be considered in

    In this study, the D0 collaboration at FermiLab has recently measured the top-quark pair forward-backward asymmetry in p¯p → tt¯X reactions as a function of the tt¯ invariant mass Mtt¯. The D0 result for AFB(Mtt¯ > 650 GeV) is smaller than AFB(Mtt¯) obtained for small values of Mtt¯, which may indicate an “increasing-decreasing” behavior for AFB(Mtt¯ > Mcut). This behavior is not explained using conventional renormalization scale setting, or even by a next-to-next-to-leading order (N2LO) QCD calculation—one predicts a monotonically increasing behavior. In the conventional scale-setting method, one simply guesses a single renormalization scale μr for the argument of the QCD running coupling and then varies it over an arbitrary range. However, the conventional method has inherent difficulties.

    The measurements of R/sub b/= sigma (e/sup +/e/sup -/ to bb)/ sigma (e/sup +/e/sup -/ to qq) and of the b quark forward-backward charge asymmetry, A/sub fb//sup b/, at centre-of-mass energies above the Z pole are described. The measurement of R/sub b/ is performed at square root (s) between 130 and 189 GeV using a b-tagging method that exploits the relatively large decay length of b-hadrons. The measurement of A/sub fb//sup b/ is performed using the large statistics event sample collected at square root (s)=189 GeV with a lepton-tag analysis based on the selection of prompt muons and electrons. The results at square root (s)=189 GeV are R/sub b /=0.163+or-0.013(stat.)+or-0.005(syst.), A/sub fb//sup b /=0.61+or-0.18(stat.)+or-0.09(syst.). (22 refs).

  9. Hydrodynamics and morphodynamics of shallow tidal channels and intertidal flats. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Friedrichs, C.T.

    1993-02-01

    In this thesis, mechanisms which control morphodynamics of shallow tidal embayments are investigated analytically. In the process of exploring these mechanisms (specifically asymmetries in bottom stress), Tau, basis momentum and mass balances which govern flow in these systems are clarified. Temporal asymmetries in Tau are investigated via a new perturbation scheme which quantifies nonlinear processes and combines geometric controls on asymmetry into a single non-dimensional parameter. Implications of spatial asymmetries in Tau are investigated through stability criteria based on a uniform distribution of Tau. Morphologic observations of both tidal channels and intertidal flats are consistent with a uniform distribution of Tau at equilibrium. Investigation of morphodynamic mechanisms leads to scalings of momentum and continuity which diverge from classical models. Scalings for prismatic channels with strong tidal asymmetries indicate friction often dominates acceleration in the momentum equation. The resulting zero-inertia balance gives a time-varying diffusion equation which requires along-channel amplitude to decay. Uniform Tau justifies a new scaling of continuity for exponentially-shaped channels. In such channels, along-channel gradients in tidal velocity are small and are often dominated by gradients in cross-sectional area. The resulting first-order wave equation allows only amplitude, forward propagating waveforms which are independent of channel length. Tidal channels Hydrodynamics, Tidal flats.

  10. Modelling the water mass exchange through navigational channels connecting adjacent coastal basins - application to the Channel of Potidea (North Aegean Sea

    Full Text Available The research objective is the detection of the mechanism of the water mass exchange through a navigational channel connecting two adjacent coastal basins. The research involves the application of a mathematical model in parallel to in-situ measurements. The hydrodynamic circulation in the greater area of the NW Aegean Sea is modeled by means of a barotropic circulation model. Wind, Coriolis and Tide are the main forcings taken into account. The flow through the channel is resolved at a subgrid scale by means of a local open channel flow model. The comparison between field measurements, recorded during a limited period, and the model results supports the model verification. The study is integrated by an operational application of the model under various realistic forcings. The results help to gain a better understanding of the mechanisms regulating the water mass exchange and the consequent interaction between two adjacent connected coastal basins. From the case study of the Potidea channel it is revealed that the water mass exchange under mean wind forcing is of the same order as the one induced by the tidal forcing.

  11. Implementation of Linear Pipe Channel Network to Estimate Hydraulic Parameters of Fractured Rock Masses

    Modeling of fluid flow is important in geological, petroleum, environmental, civil and mining engineering. Fluid flow through fractured hard rock is very much dependent on the fracture network pattern in the rock mass and on the flow behavior through these fractures. This research deals with fluid flow behavior through fractures at an abandoned copper mine in southeast Korea. An injection well and three observation wells were installed at the mine site to monitor the hydraulic heads induced by injection of fresh water. A series of packer tests were performed to estimate the rock mass permeability and corresponding effective hydraulic aperture of the fractures. The three dimensional stochastic fracture network model was built and validated for the mine site. The two dimensional linear pipe network systems were constructed in directions of the observation wells using the fracture network model. A procedure of the fluid flow analysis on two dimensional discrete domain was applied to estimate the conductance, flow quantity and nodal head in the 2-D linear pipe channel network. The present results indicate that fracture geometry parameters (orientation, density and size) play an important role in the hydraulic characteristics of fractured rock masses.

    1. Summary In the framework of the EC funded project, PERSEUS (WP3, Subtask 3.3.1: Repeated glider sections in key channels and sub-basin) and with the support of JERICO TNA (EU-FP7), a deep water glider (up to 1000m) was deployed from the R/V Tethys in the Sardinia Channel and has carried out 3 return trips during the period spanning from the 16th of August 2014 to the 19th of September 2014. The Gilder was equipped with CTD, O2 sensors, Fluorometers (ChlA), back scattering from 470 to 880 nm and was programmed to follow a path close to SARAL satellite track #887. During this experiment, a significant dataset, as never obtained before for this area, has been collected. The innovation stands in the high spatial resolution, in the temporal repetitivity and in the number of parameters sampled simultaneously. The first step of the work will focuses on the analysis of the hydrological properties of the existing water masses in the area. 2. Frame and aim of the experiment The Sardinia Channel is a zonally oriented passage connecting the Algerian and the Tyrrhenian basins, with a sill depth of about 1900 m. In spite of the considerable amount of work achieved and accurate results obtained about the circulation in the Western Mediterranean Sea, during the last 20 years, the Sardinia Channel is still one of the region where the dynamical processes and water exchanges are not clearly identified. Previous studies (Garzoli S. and C. Maillard, 1979, and Ozturgut Erdogan, 1975) pointed out the complexity of the processes in the region and the role of the bottom topography in sustaining them, and provided a first estimation of the involved fluxes. The main knowledge about the water masses crossing this region mostly concerns the AW (Atlantic Water) and the LIW (Levantine Intermediate Water). Along the Algerian coast, the AW is transported mainly by the Algerian current (AC Millot, 1985) from which the anticyclonic Algerian eddies (AEs, Puillat et al., 2002; Taupier-Letage et al

  13. Heat-and-mass transfer during a laminar dissociating gas flow in eccentric annular channels

    International Nuclear Information System (INIS)

    An algorithm to calculate heat-and-mass transfer processes during dissociating gas laminar flow in an eccentric annular channels is considered. Analytical solutions of the heat transfer equations for a rod clodding and gap with boundary conditions of conjugation of temperatures and heat fluxes have been used to determine temperature field. This has made it possible to proceed from slution of the conjugate problem to solution of the equation of energy only for the coolant. The results of calculation of temperature distribution along the cladding for different values of its eccentricity and thermal conductivity coefficient both for the case of frozen flow and in the presence of chemical reactions in the flow are given. When calculating temperatures with conjugation boundary conditions temperature gradients in azimuthal direction are far less and heat transfer in concentration diffusion is carried out mainly in radial direction

    Recently, CMS and ATLAS collaborations at LHC announced a Higgs like particle with mass near $125$GeV. Regarding this, to explore its intrinsic properties, different observables are needed to be measured precisely at the LHC for various decay channels of the Higgs. In this context, we calculate the final state lepton polarization asymmetries, namely, single lepton polarization asymmetries ($P_i$) and double lepton polarization asymmetries ($P_{ij}$) in the SM for radiative semileptonic Higgs decay $H\\to\\gamma\\tau^+\\tau^-$. In the phenomenological analysis of these lepton polarization asymmetries both tree and loop level diagrams are considered and it is found that these diagrams give important contributions in the evaluation of said asymmetries. Interestingly, it is found that in $P_{ij}$ the tree level diagrams contribute separately, which however, are missing in the calculations of $P_i$ and the lepton forward-backward asymmetries ($A_{FB}$). Similar to the other observables such as the decay rate and the l...

  15. Puzzling asymmetries

    2012-01-01

    In a recently published paper, the LHCb Collaboration has reported on a possible deviation from the Standard Model. Theorists are now working to calculate precisely this effect and to evaluate the implications that such unexpected result could have on the established theory.   The Standard Model is able to predict the decay rates of particles with high precision. In most cases, experimentalists confirm the value predicted by theory and the figure is added to the official publications. However, this time, things seem to have taken a different route. Studying data collected in 2011, the LHCb Collaboration found that in a specific decay – a B particle transforming into a K particle plus two charged muons (B -> Kμ-μ+) – the branching ratio of the neutral B in the corresponding decay (i.e. B0 -> K0μ-μ+) is different from that of the positively charged B (i.e. B+ -> K+μ-μ+). Such an “isospin asymmetry&rdquo...

    Piani, Marco; Bromley, Thomas R; Napoli, Carmine; Johnston, Nathaniel; Adesso, Gerardo

    2016-01-01

    Quantum states may exhibit asymmetry with respect to the action of a given group. Such an asymmetry of states can be considered as a resource in applications such as quantum metrology, and it is a concept that encompasses quantum coherence as a special case. We introduce explicitly and study the robustness of asymmetry, a quantifier of asymmetry of states that we prove to have many attractive properties, including efficient numerical computability via semidefinite programming, and an operational interpretation in a channel discrimination context. We also introduce the notion of asymmetry witnesses, whose measurement in a laboratory detects the presence of asymmetry. We prove that properly constrained asymmetry witnesses provide lower bounds to the robustness of asymmetry, which is shown to be a directly measurable quantity itself. We then focus our attention on coherence witnesses and the robustness of coherence, for which we prove a number of additional results; these include an analysis of its specific rele...

  17. Transverse Top Quark Polarization and the ttbar Forward-Backward Asymmetry

    CERN Document Server

    Baumgart, Matthew

    2013-01-01

    The forward-backward asymmetry in top pair production at the Tevatron has long been in tension with the Standard Model prediction. One of the only viable new physics scenarios capable of explaining this anomaly is an s-channel axigluon-like resonance, with the quantum numbers of the gluon but with significant axial couplings to quarks. While such a resonance can lead to a clear bump or excess in the ttbar or dijet mass spectra, it may also simply be too broad to cleanly observe. Here, we point out that broad ttbar resonances generally lead to net top and antitop polarizations transverse to the production plane. This polarization is consistent with all discrete spacetime symmetries, and, analogous to the forward-backward asymmetry itself, is absent in QCD at leading order. Within the parameter space consistent with the asymmetry measurements, the induced polarization can be sizable, and might be observable at the Tevatron or the LHC.

  19. Magnetic asymmetries of unmagnetized planets

    International Nuclear Information System (INIS)

    This letter discusses the results produced by 3-D hybrid particle code simulations of the solar wind interaction with unmagnetized planets such as Venus and Mars. The solar wind velocity is perpendicular to the IMF in the cases studied. It is found that there are asymmetries in both the magnetic structure and shock location for spherical obstacles ranging in radius from 1,000 km to 6,000 km. The asymmetries found are due to differences in the electron and ion currents paths (diamagnetic behavior). Mass loading of 0+ was not included in these simulations

    The forward LHCb acceptance offers the possibility of measuring the top-quark pair asymmetry in a kinematic region that does not receive overwhelming dilution from the symmetric gluon-fusion channel. To investigate this possibility, two leptonic final states are identified, and analysis strategies are proposed for each channel with 14~TeV data. Leading fixed-order predictions are then provided for the relevant leptonic asymmetry variables in each channel. If backgrounds can be experimentally ...

  4. Probing the top-quark mass in the dilepton and lepton+jets channels using only lepton information

    International Nuclear Information System (INIS)

    A new method of extracting the top-quark mass is proposed. It uses only information on the transverse momentum of electrons and muons in the tt bar → dilepton and tt bar → lepton + jets decay channels. In is shown that this variable, among others, is sensitive to the top-quark mass. As it is very accurately measured, it can provide the top-quark mass with a very small systematic error and, at high enough integrated luminosity, with a very small total error

    In real economic activities,the factors that affect consumer demand are not only price,but also the services provided by retailers and the quality of the product that provided by suppliers. For their own profits,the retailers and supplies are likely to cheat,which leads to the problem of bilateral moral hazard in the supply chain activities. The authors set a linear demand function in which demand are decided by price,service and quality and investigate the issue of optimal contract design in the case of supplier-dominant channel and retailer-dominant channel respectively. The results confirms that the linear contract can solve the problem of moral hazard,what’s more,it points out that the terminal retail price and the mode of channel fees have direct impact on the design of optimal contract between retailers and suppliers in different channel power.%现实经济活动中,价格不是影响需求的唯一要素,产品质量与终端的分销服务也是重要因素。基于自身利益最大化的原则,供应商和零售商均会执行有利于自身收益的行为决策,其中可能会存在一些隐藏的欺诈行为,由此导致供应链活动中双边道德风险问题。本文分析了不同渠道力量背景下渠道活动中存在的双边道德风险问题,研究了供应商主导和零售商主导情况下的最优零供合同设计,认为线性合同可以很好地解决供应链活动中的双边道德风险问题;同时指出,终端零售价格以及通道费收取模式对不同主体拥有渠道势力下的零售商与供应商之间的最优合同设计会产生直接影响。

Two-dimensional probability density functions are derived using a kernel density estimate-based machinery.

  10. Asymmetry measures for QSOs and companions

    CERN Document Server

    Hutchings, J B

    2008-01-01

    An asymmetry index is derived from ellipse-fitting to galaxy images, that gives weight to faint outer features and is not strongly redshift-dependent. These measures are made on a sample of 13 2MASS QSOs and their neighbour galaxies, and a control sample of field galaxies from the same wide-field imaging data. The QSO host galaxy asymmetries correlate well with visual tidal interaction indices previously published. The companion galaxies have somewhat higher asymmetry than the control galaxy sample, and their asymmetry is inversely correlated with distance from the QSO. The distribution of QSO-companion asymmetry indices is different from that for matched control field galaxies at the $\\sim95%$ significance level. We present the data and discuss this evidence for tidal and other disturbances in the vicinity of QSOs.

  11. The Charge asymmetry in W bosons produced in p anti-p collisions at center of mass energy - 1.96 TeV

    Torborg, Julie M

    2005-07-01

    The primary mode of production of W{sup +} bosons in a p{bar p} collider is u + {bar d} {yields} W{sup +}. The u quark generally carries more momentum than the {bar d} and the resultant W{sup +} tends to be boosted in the proton direction. Similarly, W bosons are boosted in the anti-proton direction. This is observed as an asymmetry in the rapidity distributions of positive and negative W bosons. Measurement of this asymmetry serves as a probe of the momentum distribution of partons within the proton. These distributions are required as input to the calculation of every p{bar p} production cross section. This thesis presents the first measurement at D0 of the charge asymmetry of the W boson production cross section as measured in W {yields} ev decays in 0.3 fb{sup -1} of p{bar p} collisions collected with the D0 Detector. Theoretical predictions made using the CTEQ6.1M and MRST(2004) parton distribution functions are compared with the measurement.

  12. Effect of mass transfer on MHD free convective flow of a viscous fluid through a vertical channel

    International Nuclear Information System (INIS)

    Unsteady free convection and mass transfer flow of an incompressible, homogeneous, electrically conducting, viscous fluid through a porous medium in a vertical channel consisting of semi-infinite parallel plates is studied under the influence of uniform magnetic field applied normal to the flow. The solutions for velocity, temperature, concentration field and the expressions for skin-friction, Nusselt number and Sherwood number have been obtained using Laplace transform technique. As the solutions and the expressions obtained are in series form, the numerical values have been obtained by truncating the series when the absolute value of the last term is less than 10-6. The effects of Schmidt number, magnetic parameter, permeability parameter and time parameter on velocity field and skin-friction have been discussed for Grashof number Gr > 0 which corresponds to symmetrical cooling and Gr < 0 which corresponds to symmetrical heating of channel walls. In addition heat and mass transfer characteristics have also been discussed. (author)

  13. Beautiful asymmetry

    International Nuclear Information System (INIS)

    The LHCb experiment at CERN will allow researchers to study the difference between matter and antimatter with unprecedented accuracy, explains Roger Forty. Our current understanding of matter and forces at the subatomic scale, as embodied in the Standard Model of particle physics, is widely considered incomplete. Its most famous missing ingredient is the Higgs Boson, thought to endow all particles with mass, but there are strong indications that other pieces of the theoretical jigsaw puzzle are missing too. One of these concerns 'dark matter', the mysterious substance thought to make up more than a fifth of the universe. Postulated to account for gravitational effects that cannot be explained by the amount of visible matter alone, dark matter could be made up of exotic new particles that are not described by the Standard Model. Fortunately, there is a good chance that such particles - and the Higgs - will be created in the high-energy collisions between protons at the Large Hadron Collider (LHC). There are two approaches to discovering such new physics. The first is to try and observe the new particles directly by detecting their decay products, which will be the goal of the two giant 'general-purpose' LHC experiments ATLAS and CMS. The alternative approach is to make precision measurements of parameters that are predicted within the Standard Model and to look for deviations that could be due to as-yet-undetected particles. This is the goal of the LHCb (LHC beauty) experiment, which is dedicated to the precision study of particles that contain the bottom or beauty quark. (U.K.)

  14. Extraction of the top quark mass from the total top quark pair production cross section in the single lepton channel

    International Nuclear Information System (INIS)

    A measurement of the total t anti t production cross section in the single lepton channel is presented. The cross section is extracted in a profile likelihood fit of templates constructed from a likelihood classifier using four kinematic variables. For a top quark of mass mt=172.5 GeV, the measured cross section is 178.9±12 pb. The measurement agrees within one-standard deviation with the latest theoretical predictions. The cross section measurement is repeated for seven other values of the top quark mass ranging from 140 GeV to 200 GeV to obtain the mass dependence of the experimental cross section. By comparing this with the mass dependence of different higher-order predictions, the top quark mass is extracted. This method allows the determination of two different theoretical mass parameters: the top quark mass in the on-shell scheme mtpole and in the MS scheme anti mt(anti mt). The most precise measurement obtained is mtpole=171.2±4.5 GeV, obtained when employing the most precise higher-order calculations in the MS scheme. This value agrees within one-standard deviation with the latest Tevatron average of the best top quark mass measurements.

    High levels of gait asymmetry are associated with many pathologies. Our long-term goal is to improve gait symmetry through real-time biofeedback of a symmetry index. Symmetry is often reported as a single metric or a collective signature of multiple discrete measures. While this is useful for assessment, incorporating multiple feedback metrics presents too much information for most subjects to use as visual feedback for gait retraining. The aim of this article was to develop a global gait asymmetry (GGA) score that could be used as a biofeedback metric for gait retraining and to test the effectiveness of the GGA for classifying artificially-induced asymmetry. Eighteen participants (11 males; age 26.9 y [SD = 7.7]; height 1.8 m [SD = 0.1]; body mass 72.7 kg [SD = 8.9]) walked on a treadmill in 3 symmetry conditions, induced by wearing custom-made sandals: a symmetric condition (identical sandals) and 2 asymmetric conditions (different sandals). The GGA score was calculated, based on several joint angles, and compared between conditions. Significant differences were found among all conditions (P meaning that the GGA score is sensitive to different levels of asymmetry, and may be useful for rehabilitation and assessment.

    The photoproduction of omega mesons off protons has been studied at the Bonn ELSA accelerator from threshold to E_gamma = 1700 MeV. Linearly polarized beams were produced via coherent bremsstrahlung. Large photon asymmtries in excess of 50% were obtained, whereas the pion asymmetries from omega \\to pi^0 gamma are close to zero. The asymmetries do characteristically depend on Theta_{cm} rather than |t| and indicate s-channel resonance formation on top of t-channel exchange processes.

  19. Jet calibration and top quark mass measurement in the semi-leptonic channel in the ATLAS experiment

    International Nuclear Information System (INIS)

    The main goal of this thesis is to provide a measurement as accurate as possible of the top quark mass in the semi-leptonic decay channel. This experimental measurement is made thanks to the ATLAS detector near LHC, a proton-proton collider. The main interests for this precision measurement are the physics constraints to the theoretical models of fundamental constituents. Besides, the top quark mass is a parameter allowing to have more information on the vacuum stability at the Planck scale within the Standard Model. Jet energy calibration is crucial to this measurement. The impact of real data taking conditions on this calibration and on jet performance is detailed. The top quark mass measurement using 2011 data collected at an energy in the center-of-mass of 7 TeV is presented. It is using a tri dimensional template analysis method. The measured top quark mass is: m(top) = 172.01 ± 0.92 (stat) ± 1.17 (syst) GeV. The 2012 data collected at an energy in the center-of-mass of 8 TeV are also analysed, and a preliminary result for the top quark mass is provided: m(top) = 172.82 ± 0.39 (stat) ± 1.12 (syst) GeV, the combination of both measurements being the most accurate result of this thesis: m(top) = 172.64 ± 0.37 (stat) ± 1.10 (syst) GeV.

    The top quark plays a special role in the Standard Model of Particle Physics. With its enormous mass of about 170 GeV it is as heavy as a gold atom and is the only quark with a mass near the electroweak scale. Together with the W boson mass, the top quark mass allows indirect constraints on the mass of the hypothetical Higgs boson, which might hold the clue to the origin of mass. Top pair production with a semileptonic decay t anti t{yields}W{sup {+-}}W{sup -+}b anti b{yields}q anti ql{nu}b anti b is the ''golden channel'' for mass measurements, due to a large branching fraction and a relatively low background contamination compared to other decay channels. Top mass measurements based on this decay, performed with the matrix element method, have always been among the single best measurements in the world. In 2007, the top mass world average broke the 1% level of precision. Its measurement is no longer dominated by statistical but instead by systematic uncertainties. The reduction of systematic uncertainties has therefore become a key issue for further progress. This thesis introduces two new developments in the treatment of b jets. The first improvement is an optimization in the way b identification information is used. It leads to an enhanced separation between signal and background processes and reduces the statistical uncertainty by about 16%. The second improvement determines differences in the detector response and thus the energy scales of light jets and b jets. Thereby, it addresses the major source of systematic uncertainty in the latest top mass measurements. The method was validated on Monte Carlo events at the generator level, calibrated with fully simulated events, including detector simulation, and applied to D0 Run II data corresponding to 1 fb{sup -1} of integrated luminosity. Possible sources of systematic uncertainties were studied. The top mass is measured to be: m{sub t}=(169.2{+-}3.5(stat.){+-}1.0(syst.)) GeV. The

    Oxytetracycline (OTC) has been extensively used for marking a variety of fish species, but has never been successfully used to mark channel catfish Ictalurus punctatus. Channel catfish fingerlings (~ 25 mm TL) obtained from the Oklahoma Department of Wildlife Conservation at Byron Fish Hatchery were kept in Living Streams (791 to 1,018 L) equipped with recirculation units. Marking trials consisted of immersing channel catfish in one of three concentrations (250, 450, and 700 mg/L) OTC hydrochloride [HCl] for 6 hours. Samples of channel catfish were obtained from each group at 1-week and 4-week postimmersion. Lapilli otoliths and pectoral spines were removed to assess mark presence with an epi-fluorescent compound microscope. After one week, no marks were detected on pectoral spines for all treatments, mark detection on otoliths depended on concentration, but never exceeded 43% (700 mg/L). After four weeks, all otoliths and pectoral spines were determined marked for 700 mg/L OTC, 20% for fish immersed in 450 mg/L OTC, and 0% were marked after four weeks at the 250 mg/L OTC. Results show, channel catfish fingerlings can be successfully marked with immersion in OTC at 700 mg/L for at least 6 hours.

  3. Measurement of Z0 lepton coupling asymmetries

    International Nuclear Information System (INIS)

    Polarized Z0's from e+e- collisions at the SLAC Linear Collider (SLC) have been used to determine the asymmetry parameters Ae, Aμ and Aτ from the leptonic decay channels. This is the first direct measurement of Aμ. The data have been gathered by the SLC Large Detector (SLD) with the electron polarization averaging 63% during the 1993 data taking period and 77% in 1994-95. A maximum likelihood procedure as well as cross section asymmetries was used to measure the asymmetry parameters from the differential cross sections for equal luminosities of left- and right-handed electron beams. The polarization-dependent muon-pair distributions give Aμ = 0.102 ±0.034 and the tau-pairs give Aτ = 0.195 ±0.034. The initial state electronic couplings in all three leptonic channels as well as the final state angular distribution in the e+e- final state measure Ae to be Ae = 0.152±0.012. Assuming lepton universality and defining a global leptonic asymmetry parameter Ae-μ-τ = 0.151±0.011. This global leptonic asymmetry value translates directly into sin2θWeff=0.2310±0.0014 at the Z0 pole

    The Faroe-Shetland Channel (FSC) is an important conduit for the poleward flow of Atlantic water towards the Nordic Seas and, as such, it plays an integral part in the Atlantic's thermohaline circulation. Mixing processes in the FSC are thought to result in an exchange of properties between the channel's inflow and outflow, with wider implications for this circulation; the nature of this mixing in the FSC is, however, uncertain. To constrain this uncertainty, we used a novel empirical method known as Parametric Optimum Multi-Parameter (POMP) analysis to objectively quantify the distribution of water masses in the channel in May 2013. This was achieved by using a combination of temperature and salinity measurements, as well as recently available nutrient and δ18O measurements. The outcomes of POMP analysis are in good agreement with established literature and demonstrate the benefits of representing all five water masses in the FSC. In particular, our results show the recirculation of Modified North Atlantic Water in the surface layers, and the pathways of Norwegian Sea Arctic Intermediate Water and Norwegian Sea Deep Water from north to south for the first time. In a final step, we apply the mixing fractions from POMP analysis to decompose the volume transport through the FSC by water mass. Despite a number of caveats, our study suggests that improved estimates of the volume transport of Atlantic inflow towards the Arctic and, thus, the associated poleward fluxes of salt and heat are possible. A new prospect to more accurately monitor the strength of the FSC branch of the thermohaline circulation emerges from this study.

  5. Measurement of the top quark mass in the fully hadronic top antitop decay channel with the ATLAS detector

    2013-07-30

    A measurement of the top quark mass in the fully hadronic top-antitop decay channel is presented. The measurement uses data recorded with the ATLAS detector from proton-proton collisions provided by the LHC in 2011. The data were taken at a centre-of-mass energy of {radical}(s)=7 TeV and correspond to an integrated luminosity of about 4.7 fb{sup -1}.To measure the top quark mass a template technique is used, based on the so-called R{sub 3/2} estimator which is built from the invariant mass ratio of the hadronically decaying top quarks and W bosons. A kinematic likelihood fit is performed to properly reconstruct the t anti t decay. The multijet background to the fully hadronic t anti t signal is modelled from data by means of an ABCD method, allowing for a precise prediction of kinematical distributions in background events. The top quark mass is measured to be m{sub top}=175.1{+-}1.4(stat.){+-}1.8(syst.) GeV/c{sup 2}, with the dominant sources of systematic uncertainty coming from the jet energy scale and the residual b-jet energy scale.

    We explore the effect of nuclear mass on the laser-driven electron localization process. We dissociate a mixed H2 and D2 target with intense, carrier-envelope-phase (CEP) stable 6 fs laser pulses and detect the products in a reaction microscope. We observe a very strong CEP-dependent asymmetry in proton and deuteron emission for low dissociation energy channels. This asymmetry is stronger for H2 than for D2. We also observe a large CEP offset between the asymmetry spectra for H2 and D2. Our theoretical simulations, based on a one-dimensional two-channel model, agree very well with the asymmetry spectra, but fail to account properly for the phase difference between the two isotopes.

  8. Hidden systematics of fission channels

    2013-12-01

    Full Text Available It is a common procedure to describe the fission-fragment mass distributions of fissioning systems in the actinide region by a sum of at least 5 Gaussian curves, one for the symmetric component and a few additional ones, together with their complementary parts, for the asymmetric components. These components have been attributed to the influence of fragment shells, e.g. in the statistical scission-point model of Wilkins, Steinberg and Chasman. They have also been associated with valleys in the potential-energy landscape between the outer saddle and the scission configuration in the multi-channel fission model of Brosa. When the relative yields, the widths and the mean mass-asymmetry values of these components are fitted to experimental data, the mass distributions can be very well reproduced. Moreover, these fission channels are characterised by specific values of charge polarisation, total kinetic energy and prompt-neutron yields. The present contribution investigates the systematic variation of the characteristic fission-channel properties as a function of the composition and the excitation energy of the fissioning system. The mean position of the asymmetric fission channels in the heavy fragment is almost constant in atomic number. The deformation of the nascent fragments at scission, which is the main source of excitation energy of the separated fission fragments ending up in prompt-neutron emission, is found to be a unique function of Z for the light and the heavy fragment of the asymmetric fission channels. A variation of the initial excitation energy of the fissioning system above the fission saddle is only seen in the neutron yield of the heavy fragment. The charge polarisation in the two most important asymmetric fission channels is found to be constant and to appreciably exceed the macroscopic value.

    Digital breast tomosynthesis (DBT) is a 3D mammography technique that promises better visualization of low contrast lesions than conventional 2D mammography. A wide range of parameters influence the diagnostic information in DBT images and a systematic means of DBT system optimization is needed. The gold standard for image quality assessment is to perform a human observer experiment with experienced readers. Using human observers for optimization is time consuming and not feasible for the large parameter space of DBT. Our goal was to develop a model observer (MO) that can predict human reading performance for standard detection tasks of target objects within a structured phantom and subsequently apply it in a first comparative study. The phantom consists of an acrylic semi-cylindrical container with acrylic spheres of different sizes and the remaining space filled with water. Three types of lesions were included: 3D printed spiculated and non-spiculated mass lesions along with calcification groups. The images of the two mass lesion types were reconstructed with 3 different reconstruction methods (FBP, FBP with SRSAR, MLTRpr) and read by human readers. A Channelized Hotelling model observer was created for the non-spiculated lesion detection task using five Laguerre-Gauss channels, tuned for better performance. For the non-spiculated mass lesions a linear relation between the MO and human observer results was found, with correlation coefficients of 0.956 for standard FBP, 0.998 for FBP with SRSAR and 0.940 for MLTRpr. Both the MO and human observer percentage correct results for the spiculated masses were close to 100%, and showed no difference from each other for every reconstruction algorithm.

  10. Disks in a narrow channel jammed by gravity and centrifuge: profiles of pressure, mass density and entropy density

    International Nuclear Information System (INIS)

    This work investigates jammed granular matter under conditions that produce heterogeneous mass distributions on a mesoscopic scale. We consider a system of identical disks that are confined to a narrow channel, open at one end and closed off at the other end. The disks are jammed by the local pressure in a gravitational field or centrifuge. All surfaces are hard and frictionless. We calculate the profiles of pressure, mass density and entropy density on a mesoscopic length scale under the assumption that the jammed states are produced by random agitations of uniform intensity along the channel. These profiles exhibit trends and features governed by the balancing of position-dependent forces and potential energies. The analysis employs a method of configurational statistics that uses interlinking two-disk tiles as the fundamental degrees of freedom. Configurational statistics weighs the probabilities of tiles according to competing potential energies associated with gravity and centrifugation. Amendments account for the effects of the marginal stability of some tiles due to competing forces. (paper)

  11. Studies on the top quark mass measurement in the all-hadronic t anti t decay channel with ATLAS

    International Nuclear Information System (INIS)

    Prospects for measuring the top quark mass in the t anti t all-hadronic channel with the ATLAS detector are investigated. A robust analysis is developed on Monte Carlo simulations at √(s)=10 TeV, considering 200 pb-1 of integrated luminosity. The event selection is based on a set of topological variables and on two b-tagged jets. The top quark mass is measured by a χ2 fitting procedure on the reconstructed invariant mass distribution and the fit result is corrected for missing b-jet energy calibration. With a top quark mass of mMCt=172.5 GeV as input to the simulation, the proposed method yields to a result of mt=173.4±2.1 vertical stroke stat±7.3 vertical stroke sys GeV for a typical pseudo-experiment. The main contribution to the systematic error comes from the jet energy scale uncertainty. Studies on the performance of the jet calibration method used, called Local Hadron Calibration, are performed both with Monte Carlo simulations and with first ATLAS data collected for pp collisions at √(s)=900 GeV.

    We present measurements of the top quark mass using the \\mT2, a variable related to the transverse mass in events with two missing particles. We use the template method applied to t\\tbar dilepton events produced in p\\pbar collisions at Fermilab's Tevatron and collected by the CDF detector. From a data sample corresponding to an integrated luminosity of 3.4 \\invfb, we select 236 t\\tbar candidate events. Using the \\mT2 distribution, we measure the top quark mass to be M_{Top} = 168.0^{+4.8}_{-4.0} $\\pm$ {2.9} GeV/c^{2}. By combining the \\mT2 with the reconstructed top mass distributions based on a neutrino weighting method, we measure M_{top}=169.3 $\\pm$ 2.7 $\\pm$ 3.2 GeV/c^{2}. This is the first application of the \\mT2 variable in a mass measurement at a hadron collider.

  15. Mass Transport Effects in Suspended Waveguide Biosensors Integrated in Microfluidic Channels

    Full Text Available Label-free optical biosensors based on integrated photonic devices have demonstrated sensitive and selective detection of biological analytes. Integrating these sensor platforms into microfluidic devices reduces the required sample volume and enables rapid delivery of sample to the sensor surface, thereby improving response times. Conventionally, these devices are embedded in or adjacent to the substrate; therefore, the effective sensing area lies within the slow-flow region at the floor of the channel, reducing the efficiency of sample delivery. Recently, a suspended waveguide sensor was developed in which the device is elevated off of the substrate and the sensing region does not rest on the substrate. This geometry places the sensing region in the middle of the parabolic velocity profile, reduces the distance that a particle must travel by diffusion to be detected, and allows binding to both surfaces of the sensor. We use a finite element model to simulate advection, diffusion, and specific binding of interleukin 6, a signaling protein, to this waveguide-based biosensor at a range of elevations within a microfluidic channel. We compare the transient performance of these suspended waveguide sensors with that of traditional planar devices, studying both the detection threshold response time and the time to reach equilibrium. We also develop a theoretical framework for predicting the behavior of these suspended sensors. These simulation and theoretical results provide a roadmap for improving sensor performance and minimizing the amount of sample required to make measurements.

    During 1993 and 1995 LEP was run at 3 energies near the Z$^0$ peak in order to give improved measurements of the mass and width of the resonance. During 1994, LEP operated only at the Z$^0$peak. In total DELPHI accumulated data corresponding to an integrated luminosity of approximately 116~pb$^{-1}$. Analyses ofthe hadronic cross-sections and of the cross-sections and forward-backward asymmetries in the leptonic channels used the most precise evaluations of the LEP energies. In the dimuon channel, events with a photon radiated from the initialstate have been used to probe the cross-sections and asymmetries down to PETRA energies.Model independent fits to all DELPHI lineshape and asymmetry data from 1990 to 1995have been carried out giving values ofthe resonance parameters:\\MZ & = & 91.1863\\pm0.0028~\\GeV \\\\\\GZ & = & ~2.4876\\pm0.0041~\\GeV \\\\ \\sigma_{0} & = & 41.578\\pm0.069~\

  19. Enhancement effect of asymmetry on the thermal conductivity of double-stranded chain systems

    International Nuclear Information System (INIS)

    Using nonequilibrium molecular dynamics simulations, we study the thermal conductivity of asymmetric double chains. We couple two different single chains through interchain coupling to build three kinds of asymmetric double-stranded chain system: intrachain interaction, external potential, and mass asymmetric double chains. It is reported that asymmetry is helpful in improving the thermal conductivity of the system. We first propose double-heat flux channels to explain the influence of asymmetric structures on the thermal conductivity. The phonon spectral behaviour and finite size effect are also included.

  1. Transverse Top Quark Polarization and the ttbar Forward-Backward Asymmetry

    OpenAIRE

    Baumgart, Matthew; Tweedie, Brock

    2013-01-01

    The forward-backward asymmetry in top pair production at the Tevatron has long been in tension with the Standard Model prediction. One of the only viable new physics scenarios capable of explaining this anomaly is an s-channel axigluon-like resonance, with the quantum numbers of the gluon but with significant axial couplings to quarks. While such a resonance can lead to a clear bump or excess in the ttbar or dijet mass spectra, it may also simply be too broad to cleanly observe. Here, we poin...

    Physical models for the hemispherical power asymmetry in the cosmic microwave background (CMB) reported by the Planck Collaboration must satisfy CMB constraints to the homogeneity of the Universe and quasar constraints to power asymmetries. We survey a variety of models for the power asymmetry and show that consistent models include a modulated scale-dependent isocurvature contribution to the matter power spectrum or a modulation of the reionization optical depth, gravitational-wave amplitude, or scalar spectral index. We propose further tests to distinguish between the different scenarios.

    The quality of measurement of heat capacity by differential scanning calorimetry (DSC) is based on strict symmetry of the twin calorimeter, which is important for temperature-modulated DSC. Heat capacities for sapphire-filled and empty aluminium calorimeters (pans) under designed cell imbalance caused by different pan-masses were measured. In addition, positive and negative signs of asymmetry were explored by analyzing the phase-shift between temperature and heat flow for sapphire and empty runs. The phase shifts change by more than 18{degree} depending on asymmetry sign. Once the asymmetry sign is determined, the asymmetry correction for modulated DSC can be made.

    By reversing the Schottky barrier-height asymmetry in hot-electron semiconductor-metal-semiconductor ballistic spin filtering spin detectors, we have achieved: 1. Demonstration of >50% spin polarization in silicon, resulting from elimination of the ferromagnet/silicon interface on the transport channel detector contact, and 2. Evidence of spin transport at temperatures as high as 260K, enabled by an increase of detector Schottky barrier height.

    To establish an automatic and online microfluidic chip-mass spectrometry (chip-MS) system, a device was designed and fabricated for microsampling by a hybrid capillary. The movement of the capillary was programmed by a computer to aspirate samples from different microfluidic channels in the form of microdroplets (typically tens of nanoliters in volume), which were separated by air plugs. The droplets were then directly analyzed by MS via paper spray ionization without any pretreatment. The feasibility and performance were demonstrated by a concentration gradient experiment. Furthermore, after eliminating the effect of nonuniform response factors by an internal standard method, determination of the association constant within a noncovalent protein-protein complex was successfully accomplished with the MS-based titration indicating the versatility and the potential of this novel platform for widespread applications.

    Indeed, in this mass region (A ~ 100 models predict that shape transitions can occur at high spin values and relatively scarce data exist in the literature about coincidence measurements between evaporation residues and light charged particles. Signals of shape transitions can be found in the variations of the lineshape of high energy gamma rays emitted from the de-excitation of GDR states gated on different region of angular momenta. For this purpose it is important to keep under control the FE and FF processes, to regulate the statistical model parameters and to control the onset of possible pre-equilibrium emissions from 300 to 600 MeV bombarding energy.

    A measurement of the top quark mass using events with one charged lepton, missing transverse energy, and jets in the final state, collected by the D0 detector from p-pbar collisions at sqrt{s} = 1.96 TeV at the Fermilab Tevatron collider, is presented. A constrained fit is used to fully reconstruct the kinematics of the events. For every event a top quark mass likelihood is calculated taking into account all possible jet assignments and the probability that an event is signal or background. Lifetime-based identification of b jets is employed to enhance the separation between t-tbar signal and background from other physics processes and to improve the assignment of the observed jets to the quarks in the t-tbar hypothesis. We extract a multiplicative jet energy scale factor JES in-situ, greatly reducing the systematic effect related to the jet energy measurement. In a data sample with an integrated luminosity of 425 pb-1, we observe 230 candidate events, with an estimated background of 123 events, and measure m...

  9. Asymmetry in the angular distributions of spectator-nucleons

    International Nuclear Information System (INIS)

    The asymmetry in the angular distributions of spectator-nucleons has been studied in dp interactions, and it has been found that the sign of the asymmetry depends on the reaction channel. It is shown that in the momentum interval 0-200 MeV/c of spectators basic features of the angular distributions can be reproduced in the framework of the spectator model taking into account the energy dependence of the NN cross section and the flux-factor

  10. Measurement of the top quark mass with the matrix element method in the semileptonic decay channel at D0

    The top quark plays a special role in the Standard Model of Particle Physics. With its enormous mass of about 170 GeV it is as heavy as a gold atom and is the only quark with a mass near the electroweak scale. Together with theW boson mass, the top quark mass allows indirect constraints on the mass of the hypothetical Higgs boson, which might hold the clue to the origin of mass. Top pair production with a semileptonic decay t $\\bar{t}$ →W±W b$\\bar{b}$ →q $\\bar{t}$lnb$\\bar{b}$ is the ”golden channel” for mass measurements, due to a large branching fraction and a relatively low background contamination compared to other decay channels. Top mass measurements based on this decay, performed with the matrix element method, have always been among the single best measurements in the world. In 2007, the top mass world average broke the 1% level of precision. Its measurement is no longer dominated by statistical but instead by systematic uncertainties. The reduction of systematic uncertainties has therefore become a key issue for further progress. This thesis introduces two new developments in the treatment of b jets. The first improvement is an optimization in the way b identification information is used. It leads to an enhanced separation between signal and background processes and reduces the statistical uncertainty by about 16%. The second improvement determines differences in the detector response and thus the energy scales of light jets and b jets. Thereby, it addresses the major source of systematic uncertainty in the latest top mass measurements. The method was validated on Monte Carlo events at the generator level, calibrated with fully simulated events, including detector simulation, and applied to D0 Run II data corresponding to 1 fb-1 of integrated luminosity. Possible sources of systematic uncertainties were studied. The top mass is measured to be: mt = (169.2±3.5(stat.)±1.0(syst.)) GeV . The

    We report our recent effort for the extraction of resonance parameters (complex pole mass and residues etc.) associated with Lambda* and Sigma* hyperons. This was accomplished via a comprehensive partial-wave analysis of the data for K^- p --> barK N, pi Sigma, pi Lambda, eta Lambda, K Xi reactions from the thresholds up to W=2.1 GeV within a dynamical coupled-channels approach. The results suggest a possible existence of new narrow J^P=3/2^+ \\Lambda resonance with pole mass 1671^{+2}_{-8} -i(5^{+11}_{-2}) MeV, located close to the eta Lambda threshold. This resonance is found to be responsible for reproducing the data for K^-p --> eta Lambda differential cross sections near the threshold, and thus the data seem favor its existence. The extracted poles for J^P=1/2^- Lambda resonances below the barK N threshold, including Lambda(1405), are also presented.

    Quantum states may exhibit asymmetry with respect to the action of a given group. Such an asymmetry of states can be considered a resource in applications such as quantum metrology, and it is a concept that encompasses quantum coherence as a special case. We introduce explicitly and study the robustness of asymmetry, a quantifier of asymmetry of states that we prove to have many attractive properties, including efficient numerical computability via semidefinite programming and an operational interpretation in a channel discrimination context. We also introduce the notion of asymmetry witnesses, whose measurement in a laboratory detects the presence of asymmetry. We prove that properly constrained asymmetry witnesses provide lower bounds to the robustness of asymmetry, which is shown to be a directly measurable quantity itself. We then focus our attention on coherence witnesses and the robustness of coherence, for which we prove a number of additional results; these include an analysis of its specific relevance in phase discrimination and quantum metrology, an analytical calculation of its value for a relevant class of quantum states, and tight bounds that relate it to another previously defined coherence monotone.

    The authors report a measurement of the top quark mass, m{sub t}, obtained from p{bar p} collisions at {radical}s = 1.96 TeV at the Fermilab Tevatron using the CDF II detector. They analyze a sample corresponding to an integrated luminosity of 1.9 rfb{sup -1}. They select events with an electron or muon, large missing transverse energy, and exactly four high-energy jets in the central region of the detector, at least one of which is tagged as coming from a b quark. They calculate a signal likelihood using a matrix element integration method, where the matrix element is modified by using effective propagators to take into account assumptions on event kinematics. The event likelihood is a function of m{sub t} and a parameter JES that determines in situ the calibration of the jet energies. They use a neural network discriminant to distinguish signal from background events. They also apply a cut on the peak value of each event likelihood curve to reduce the contribution of background and badly reconstructed events. Using the 318 events that pass all selection criteria, they find m{sub t} = 172.7 {+-} 1.8 (stat. + JES) {+-} 1.2(syst.) GeV/c{sup 2}.

  14. Suppressed $B \\to PV $ CP asymmetry: CPT constraint

    2016-01-01

    Charge Parity asymmetry in charmless B meson decays is a key issue to be understood. Many theoretical calculations have been performed using short distance factorization approaches which, in general, do not take into account the CPT invariance constraint. For each channel with CP violation there is an equal amount of CP asymmetry in another channel or other channels, with an opposite sign. This happens if these channels are coupled through final state interactions (FSI). In the specific process $B\\to PV$, involving one pseudo-scalar and one vector particle in the final state, we argue that the CP asymmetry, inherent from a short distance mechanism, could be suppressed due to the CPT constraint. In this case, we propose a sensitive and practical experimental method to identify even a small CP asymmetry, which provides the values for $A_{CP}$ without the need for an amplitude analysis. This method, if applied directly to data, will enable to extract the CP asymmetry information in a model independent way and ch...

  15. Sediment, water column, and open-channel denitrification in rivers measured using membrane-inlet mass spectrometry

    Riverine biogeochemical processes are understudied relative to headwaters, and reach-scale processes in rivers reflect both the water column and sediment. Denitrification in streams is difficult to measure, and is often assumed to occur only in sediment, but the water column is potentially important in rivers. Dissolved nitrogen (N) gas flux (as dinitrogen (N2)) and open-channel N2 exchange methods avoid many of the artificial conditions and expenses of common denitrification methods like acetylene block and 15N-tracer techniques. We used membrane-inlet mass spectrometry and microcosm incubations to quantify net N2 and oxygen flux from the sediment and water column of five Midwestern rivers spanning a land use gradient. Sediment and water column denitrification ranged from below detection to 1.8 mg N m-2 h-1 and from below detection to 4.9 mg N m-2 h-1, respectively. Water column activity was variable across rivers, accounting for 0-85% of combined microcosm denitrification and 39-85% of combined microcosm respiration. Finally, we estimated reach-scale denitrification at one Midwestern river using a diel, open-channel N2 exchange approach based on reach-scale metabolism methods, providing an integrative estimate of riverine denitrification. Reach-scale denitrification was 8.8 mg N m-2 h-1 (95% credible interval: 7.8-9.7 mg N m-2 h-1), higher than combined sediment and water column microcosm estimates from the same river (4.3 mg N m-2 h-1) and other estimates of reach-scale denitrification from streams. Our denitrification estimates, which span habitats and spatial scales, suggest that rivers can remove N via denitrification at equivalent or higher rates than headwater streams.

  16. Sharing but not caring: dark matter and the baryon asymmetry of the universe

    Bernal, Nicolás; Fong, Chee Sheng; Fonseca, Nayara

    2016-09-01

    We consider scenarios where Dark Matter (DM) particles carry baryon and/or lepton numbers, which can be defined if there exist operators connecting the dark to the visible sector. As a result, the DM fields become intimately linked to the Standard Model (SM) ones and can be maximally asymmetric just like the ordinary matter. In particular, we discuss minimal scenarios where the DM is a complex scalar or a Dirac fermion coupled to operators with nonzero baryon and/or lepton numbers, and that consist of only SM fields. We consider an initial asymmetry stored in either the SM or the DM sector; the main role of these operators is to properly share the asymmetry between the two sectors, in accordance with observations. After the chemical decoupling, the DM and SM sectors do not care about each other as there is only an ineffective communication between them. Once the DM mass is specified, the Wilson coefficients of these operators are fixed by the requirement of the correct transfer of the asymmetry. We study the phenomenology of this framework at colliders, direct detection and indirect detection experiments. In particular, the LHC phenomenology is very rich and can be tested in different channels such as the two same-sign leptons with two jets, monojet and monojet with a monolepton.

  17. Top quark mass measurement in the lepton+jets channel using full simulation of the CMS detector

    International Nuclear Information System (INIS)

    In summer 2008 the world largest proton-proton storage ring, the Large Hadron Collider (LHC), at CERN close to Geneva (Switzerland) will go into service. With a collision energy of 14 TeV the production cross section for top/antitop quarks (t anti t) is about 830 pb (NLO). The top quarks almost exclusively decay into a W boson and a b quark via the weak interaction. In about 44.4% of all events one of the top quarks decays into a lepton and neutrino while the other one decays into two light quarks (semileptonic decay chain). This channel therefore provides a good selection purity (lepton b tagging) and the possibility for the complete reconstruction of the hadronically decaying top quark into three jets. After a short introduction of top quark physics at the LHC and the Compact Muon Solenoid (CMS) detector, this thesis deals with the analyses of top quark reconstruction and mass measurement in two different scenarios. In the first analysis a first physics scenario is taken as a basis where no jet flavour information (e.g. b tagging) and only a reduced detector acceptance region for electron identification is assumed. It is shown that semileptonic top quark pair decays can nevertheless be identified with a signal over background ratio of about S/B=2.4. For this study signal and main background processes using full simulation of the CMS detector have been produced for an integrated luminosity of 0.1 fb-1. Especially event shape variables are adequate to compensate the missing b jet tagging. The semileptonic channel is the most promising one to rediscover the top quark at the LHC due to the lepton in the final state. In this scenario the needed integrated luminosity has been calculated to be about 2 pb-1 assuming Poisson distributions for the number of signal and background events. A second analysis focusses on the top quark mass measurement in a scenario where the CMS detector is fully equipped and has almost reached its design performance. Therefore data for an

  19. Entropy generation minimization (EGM) to optimize mass flow rate in dual channel cable-in-conduit conductors (CICCs) used for fusion grade magnets

    International Nuclear Information System (INIS)

    Highlights: • Entropy generation in CICCs is estimated using CFD. • Entropy generation minimization technique is used to optimize the mass flow rate in CICCs. • In dual channel CICC, contribution of thermal gradients to rate of entropy generation is higher as compared to contribution of velocity gradients. • At a mass flow rate of 13 g/s, higher heat transfer rate and optimum pumping power is observed. • The factors that affect entropy generation in CICCs are identified. - Abstract: Dual channel cable-in-conduit conductors (CICCs) used in tokamaks such as International Thermonuclear Experimental Reactor (ITER) consist of annular channel packed with superconducting strands and a clear central channel separated by a spiral from the annular channel. Supercritical helium (SHe) operating at 4.5 K and 0.5 MPa is used for forced convective cooling of CICC. Pressure drop is inevitable in the process of forced convective cooling, leading to the development of velocity gradients and temperature gradients. These velocity gradients and thermal gradients result in entropy generation in CICCs. The present work aims at estimating volumetric rate of entropy generation (EG) in dual channel CICC. Subsequently, entropy generation minimization (EGM) technique is used to find optimum mass flow rate at which volumetric rate of EG is minimum. Pumping power and heat transfer corresponding to minimum rate of EG are also calculated. Computational fluid dynamics (CFD) is used as a tool to estimate EG as the analytical solution for turbulent forced convective flows requires inaccurate simplifications. A three dimensional model of dual channel CICC is developed in GAMBIT-2.1 and solved using a compatible solver FLUENT-6.3.26. The annular region of CICC is assumed to be porous and the central channel is assumed as clear region for EG analysis using CFD. The pressure gradients and heat transfer coefficient estimated from the simulations are validated against relevant experimental

    The present communication describes the application of bilateral asymmetry in forensic casework and anthropological research. Bilateral asymmetry is normal in the human body. The body's asymmetry is attributable to genetic and environmental (evolutionary) reasons. Handedness is a factor related to bilateral asymmetry. Gutnik et al. (2015) supported previous research, showing that the dominant side of the body is stronger than the other side due to additional stress and strain, and thus has augmented musculature and increased mass. The note is intended to elaborate on the applications of body asymmetry in forensic and anthropological practice. PMID:27166335

    2013-10-11

    In addition to explaining the masses of elementary particles, the Higgs boson may have far-reaching implications for the generation of the matter content in the Universe. For instance, the Higgs boson plays a key role in two main theories of baryogenesis, namely, electroweak baryogenesis and leptogenesis. In this Letter, we propose a new cosmological scenario where the Higgs chemical potential mediates asymmetries between visible and dark matter sectors, either generating a baryon asymmetry from a dark matter asymmetry or vice versa. We illustrate this mechanism with a simple model with two new fermions coupled to the Higgs boson and discuss the associated signatures. PMID:24160589

    In 2010, the COMPASS experiment at CERN took data with a 160 GeV μ{sup +} beam and a transversely polarized NH{sub 3} target. In this thesis, this data is analyzed for azimuthal target spin asymmetries, including five single spin and three double spin asymmetries in hard exclusive ω meson production. This thesis is the worldwide first analysis investigating on azimuthal asymmetries in exclusive ω muoproduction (μ'p→μ'+p'+ω→μ'+p'+π{sup +}π{sup -}π{sup 0}). The analysis is confronted with several challenges beside the small cross section of the examined process. The detection of two photons in the final state requires an excellent performance of the electromagnetic calorimeters as well as a good understanding of the detector. To increase the yield of reconstructed γ pairs from a decaying π{sup 0} meson, a decay product of the ω meson, extensive studies relating to performance of the calorimeters were necessary. Firstly the time information of the calorimeters had to be parametrized in dependence of the cluster energy to ensure the assignment of beam particle and photon due to a correlation in time. Secondly, a parametrization of the invariant mass of the photon pair was performed in terms of the energy of the reconstructed π{sup 0}, for the better discrimination of signal and background. In the setup with the transversely polarized target, the recoiled proton cannot be detected. Thus in order to ensure the exclusivity of the process, the missing energy is calculated. The signal region, defined at vertical stroke E{sub miss} vertical stroke < 3GeV, contains ω mesons from exclusive events as well as from semi-inclusive production. Hence the understanding of non-exclusive background is essential for the further analysis. For this purpose, a semiinclusive Monte Carlo sample is studied. In order to reach a better agreement of the Monte Carlo and data, like-sign samples from both, real data and Monte Carlo, are compared and the

    Full Text Available Asymmetry and symmetry coexist in natural and human processes.  The vital role of symmetry in art has been well demonstrated. This article highlights the complementary role of asymmetry. Further we show that the interaction of asymmetric action (recursion and symmetric opposition (sinusoidal waves are instrumental in generating creative features (relatively low entropy, temporal complexity, novelty (less recurrence in the data than in randomized copies and complex frequency composition. These features define Bios, a pattern found in musical compositions and in poetry, except for recurrence instead of novelty. Bios is a common pattern in many natural and human processes (quantum processes, the expansion of the universe, gravitational waves, cosmic microwave background radiation, DNA, physiological processes, animal and human populations, and economic time series. The reduction in entropy is significant, as it reveals creativity and contradicts the standard claim of unavoidable decay towards disorder. Artistic creations capture fundamental features of the world.

The events are obtained from nearly 230 pb{sup -1} of p{bar p} collision data collected by the D0 experiment between 2002 and 2004 during Run II. In this decay channel two neutrinos remain undetected. Extraction of the mass of the top quark by kinematic reconstruction is not possible because the event is under-constrained. Therefore, a dynamical likelihood method is developed to obtain the mass of the top quark. The mass of top quark obtained from the candidate events selected in the di-electron channel and the e{mu} channel is: 154.1 {sup +14.2}{sub -12.8}(stat.) {+-}6.6 (syst.) GeV.

    We review the concept of Bessel weighted asymmetries for semi-inclusive deep inelastic scattering and focus on the cross section in Fourier space, conjugate to the outgoing hadron’s transverse momentum, where convolutions of transverse momentum dependent parton distribution functions and fragmentation functions become simple products. Individual asymmetric terms in the cross section can be projected out by means of a generalized set of weights involving Bessel functions. The procedure is applied to studies of the double longitudinal spin asymmetry in semi-inclusive deep inelastic scattering using a new dedicated Monte Carlo generator which includes quark intrinsic transverse momentum within the generalized parton model. We observe a few percent systematic offset of the Bessel-weighted asymmetry obtained from Monte Carlo extraction compared to input model calculations, which is due to the limitations imposed by the energy and momentum conservation at the given energy and hard scale Q2. We find that the Bessel weighting technique provides a powerful and reliable tool to study the Fourier transform of TMDs with controlled systematics due to experimental acceptances and resolutions with different TMD model inputs.

Elite alpine skiers with ACL-R (n = 9; 26.2 ± 11.8 months post-op) and uninjured skiers (n = 9) participated in neuromuscular screening. Vertical ground reaction force during the CMJ and SJ was assessed using dual force plate methodology to obtain phase-specific bilateral asymmetry indices (AIs) for...... kinetic impulse (CMJ and SJ phase-specific kinetic impulse AI). Dual x-ray absorptiometry scanning was used to assess asymmetry in lower body muscle mass. Compared with controls, ACL-R skiers had increased AI in muscle mass (P < 0.001), kinetic impulse AI in the CMJ concentric phase (P < 0.05), and the...

    Mechanosensitive ion channels are sensors probing membrane tension in all species; despite their importance and vital role in many cell functions, their gating mechanism remains to be elucidated. Here, we determined the conditions for releasing intact mechanosensitive channel of large conductance (M

  13. The Small Observed Baryon Asymmetry from a Large Lepton Asymmetry

    1999-01-01

    Primordial Big-Bang Nucleosynthesis (BBN) tightly constrains the existence of any additional relativistic degrees of freedom at that epoch. However a large asymmetry in electron neutrino number shifts the chemical equilibrium between the neutron and proton at neutron freeze-out and allows such additional particle species. Moreover, the BBN itself may also prefer such an asymmetry to reconcile predicted element abundances and observations. However, such a large asymmetry appears to be in conflict with the observed small baryon asymmetry if they are in sphaleron mediated equilibrium. In this paper we point out the surprising fact that in the Standard Model, if the asymmetries in the electron number and the muon number are equal (and opposite) and of the size required to reconcile BBN theory with observations, a baryon asymmetry of the Universe of the correct magnitude and sign is automatically generated within a factor of two. This small remaining discrepancy is naturally remedied in the supersymmetric Standard...

    This paper reports inclusive and differential measurements of the t anti t charge asymmetry A{sub C} in 20.3 fb{sup -1} of √(s) = 8 TeV pp collisions recorded by the ATLAS experiment at the Large Hadron Collider at CERN. Three differentialmeasurements are performed as a function of the invariant mass, transverse momentum and longitudinal boost of the t anti t system. The t anti t pairs are selected in the single-lepton channels (e or μ) with at least four jets, and a likelihood fit is used to reconstruct the t anti t event kinematics. A Bayesian unfolding procedure is performed to infer the asymmetry at parton level from the observed data distribution. The inclusive t anti t charge asymmetry is measured to be A{sub C} = 0.009 ± 0.005 (stat. + syst.). The inclusive and differential measurements are compatible with the values predicted by the Standard Model. (orig.)

    The authors study the heat and mass transfer by permanent and laminar natural convection in a channel formed by two vertical plates. At the inflow end of the channel, the plates are wet and adiabatic over a length x{sub 1}, dry and adiabatic over a central portion defined by x{sub 1}< x mass fraction of water steam distributions as a function of the different parameters are given and commented upon. It is noted that there is a diminution of the longitudinal flow rate of the air when getting closer to the out flow. (authors). 9 refs., 10 figs.

  16. Search for the Higgs boson at center-of-mass energies between 161 and 184 GeV in the 4-jet channel with OPAL

    International Nuclear Information System (INIS)

    A search for the Standard Model Higgs boson using data from e+e- collisions collected at center-of-mass energies from 161 to 184 GeV with the OPAL detector at LEP is presented. The search is applied to events in the four-jet-channel, in which the Higgs boson decays into a bb pair and the associated Z0 decays into quark and anti-quark. The data analyzed corresponds to an integrated luminosity of 75.0 pb-1. Five candidate events are observed, in agreement with the Standard Model background expectation of 6.61±0.42 (stat.) ±1.72 (syst.) events. A lower limit of 74.0 GeV is derived for the mass of the Standard Model Higgs boson at the 95% confidence level. In combination with OPAL searches in other channels a limit of 86.9 GeV is obtained.

  17. The effect of coupled mass transport and internal reforming on modeling of solid oxide fuel cells part I: Channel-level model development and steady-state comparison

    2016-02-01

    Dynamic modeling and analysis of solid oxide fuel cell systems can provide insight towards meeting transient response application requirements and enabling an expansion of the operating envelope of these high temperature systems. SOFC modeling for system studies are accomplished with channel-level interface charge transfer models, which implement dynamic conservation equations coupled with additional submodels to capture the porous media mass transport and electrochemistry of the cell. Many of these models may contain simplifications in order to decouple the mass transport, fuel reforming, and electrochemical processes enabling the use of a 1-D model. The reforming reactions distort concentration profiles of the species within the anode, where hydrogen concentration at the triple-phase boundary may be higher or lower than that of the channel altering the local Nernst potential and exchange current density. In part one of this paper series, the modeling equations for the 1-D and 'quasi' 2-D models are presented, and verified against button cell electrochemical and channel-level reforming data. Steady-state channel-level modeling results indicate a 'quasi' 2-D SOFC model predicts a more uniform temperature distribution where differences in the peak cell temperature and maximum temperature gradient are experienced. The differences are most prominent for counter-flow cell with high levels of internal reforming. The transient modeling comparison is discussed in part two of this paper series.

  19. Energy dependence of complete and incomplete fusion for mass 56 entrance channel systems at E/sub lab/ > 10 MeVnucleon

    International Nuclear Information System (INIS)

    Three entrance channels 16O + 40Ca, 28Si + 28Si, and 32S + 24Mg forming the 56Ni compound nucleus have been studied in the energy range 5 to 17 MeVnucleon. Time-of-flight measurements provided mass identification and allowed for extraction of velocity distributions. These distributions were used to identify evaporation residues and to decompose the evaporation residues yeilds into complete and incomplete fusion components using evaporation code calculations. The velocity centroids as function of angle and mass are found to put constraints on the possible pre-equilibrium emission of light particles. 16 refs., 6 figs

  20. Observation of a Higgs boson and measurement of its mass in the di-photon decay channel with the ATLAS detector at the LHC

    International Nuclear Information System (INIS)

    The Standard Model of particle physics predicts the existence of a massive scalar boson, referred to as the Higgs boson, resulting from the introduction of a doublet of complex scalar fields and the Spontaneous Symmetry Breaking mechanism, needed to generate the mass of the particles. The Higgs boson, whose mass is theoretically undetermined, has been searched for experimentally since almost half a century by various experiments. The search for the Higgs boson is one of the goals of the LHC physics program. One of the most important decay channels at the LHC is the di-photon channel, because the final state can be completely reconstructed with high precision. In this thesis, a detailed study of the photon energy response, using the ATLAS electromagnetic calorimeter has been performed. In particular, the stability and uniformity of the energy response has been tested. This study has provided a better understanding of the photon energy resolution and scale, which are very important for the determination of the systematic uncertainties on the mass and production rate in the di-photon channel. This channel had a prominent role in the discovery of a new particle compatible with the Standard Model Higgs boson by the ATLAS and CMS experiments. Using this channel as well as the improved understanding of the photon energy response, a measurement of the mass of this particle is proposed in this thesis, with the data collected in 2011 and 2012 at a center-of-mass energy of 7 TeV and 8 TeV. A mass of [126.8 ± 0.2(stat) ± 0.7(syst)] GeV/c2 is found. The calibration of the photon energy measurement with the calorimeter is the source of the largest systematic uncertainty on this measurement. Strategies to reduce this systematic error are discussed. Among them, a method to measure the amount of material upstream of the calorimeter, which provides the largest contribution to the uncertainty on the energy scale, has been developed. The energy scale measurement of the different

  1. Facial Asymmetry and Emotional Expression

    Pickin, Andrew

    2011-01-01

    This report is about facial asymmetry, its connection to emotional expression, and methods of measuring facial asymmetry in videos of faces. The research was motivated by two factors: firstly, there was a real opportunity to develop a novel measure of asymmetry that required minimal human involvement and that improved on earlier measures in the literature; and secondly, the study of the relationship between facial asymmetry and emotional expression is both interesting in its own right, and important because it can inform neuropsychological theory and answer open questions concerning emotional processing in the brain. The two aims of the research were: first, to develop an automatic frame-by-frame measure of facial asymmetry in videos of faces that improved on previous measures; and second, to use the measure to analyse the relationship between facial asymmetry and emotional expression, and connect our findings with previous research of the relationship.

  2. Measurement of Z{sup 0} lepton coupling asymmetries

    1997-07-01

    Polarized Z{sup 0}`s from e{sup +}e{sup {minus}} collisions at the SLAC Linear Collider (SLC) have been used to determine the asymmetry parameters A{sub e}, A{sub {mu}} and A{sub {tau}} from the leptonic decay channels. This is the first direct measurement of A{sub {mu}}. The data have been gathered by the SLC Large Detector (SLD) with the electron polarization averaging 63% during the 1993 data taking period and 77% in 1994-95. A maximum likelihood procedure as well as cross section asymmetries was used to measure the asymmetry parameters from the differential cross sections for equal luminosities of left- and right-handed electron beams. The polarization-dependent muon-pair distributions give A{sub {mu}} = 0.102 {+-}0.034 and the tau-pairs give A{sub {tau}} = 0.195 {+-}0.034. The initial state electronic couplings in all three leptonic channels as well as the final state angular distribution in the e{sup +}e{sup {minus}} final state measure A{sub e} to be A{sub e} = 0.152{+-}0.012. Assuming lepton universality and defining a global leptonic asymmetry parameter A{sub e-{mu}-{tau}} = 0.151{+-}0.011. This global leptonic asymmetry value translates directly into sin{sup 2}{theta}{sub W}{sup eff}=0.2310{+-}0.0014 at the Z{sup 0} pole.

  3. Same sign dimuon charge asymmetry in Bq0 - Bq0-bar system

    International Nuclear Information System (INIS)

    The recent observation of same-sign dimuon charge asymmetry (Aslb in the B meson decays by the DO collaboration has 3.9σ deviation from the Standard Model (SM) prediction. Any non-trivial contribution beyond the SM expectations is a signal of new physics (NP). The measured dimuon charge asymmetry is a linear combination of the individual flavor-specific charge asymmetries asls and asld in the Bs and Bd sectors respectively. The flavor-specific charge asymmetry is related to the mass and width difference in the Bq0 - B-barq0 system. In this paper, using the recent data on individual flavor-specific charge asymmetries, same-sign dimuon charge asymmetry is calculated. We find the same-sign dimuon charge asymmetry is enhanced from its SM value and provides signals for new physics beyond the SM. (author)

  4. Poloidal asymmetries of heavy impurities in the ASDEX upgrade plasma

    International Nuclear Information System (INIS)

    For heavy and highly charged impurities multiple mechanisms exist that produce non-constant impurities densities on the flux surfaces. As for neoclassical and turbulent transport models such an asymmetry is highly importance an effort is launched to experimentally characterize the asymmetries comparing them with theoretical expectations. In the ASDEX upgrade tokamak (AUG) is routinely observed increase of outboard tungsten density in fast rotating plasma. This asymmetry is caused by the centrifugal force pushing tungsten ions outward due to its high mass. Furthermore, the high charge makes heavy impurities sensitive to poloidal variations of the plasma potential. The variation can be generated by magnetic trapped ions heated by RF heating. In such a case, the presence of an inboard asymmetry or at least the absence of an outboard asymmetry due to the centrifugal force can be observed. Finally, ion-impurity friction enhanced by the large charge of the impurity ions may cause a relatively weak up-down asymmetry of the impurity density. The aim of this poster is to show first evidence of these asymmetries in the AUG plasmas, the description of the used methodology, and to compare with theoretical models based on the parallel force balance.

      Asymmetry is considered a challenge and often the reason for which the optimal result cannot be obtained. The explanations are many. Only rarely, the cause of the asymmetry is localized and camouflage is frequently resulting in the development a different type of asymmetry occurring in all three...... planes of space. A systematic approach to the identification of the cause of the asymmetry head precede the decision whether to correct or to camouflage. The definition of a specific treatment goal should be done only following an analysis of the likelihood that the force system necessary to perform the...

  6. Fission fragment mass distribution studies for 28Si + 197Au, 209Bi, 235U reactions

    International Nuclear Information System (INIS)

    In reactions with heavy ions, complete fusion and quasi-fission are the competing processes at energies above the Coulomb barrier. The quasi-fission process, in which the system reseparates before reaching a compact compound nucleus, is a major hurdle in forming heavy and superheavy evaporation residues (ER) in heavy-ion reactions. Fission fragment mass distribution for the fully equilibrated compound nucleus is decided at the scission point due to a long descent from saddle to scission. At higher excitation energies, the shell effects are washed out and the mass distribution is expected to be symmetric. The width of the distribution strongly depends on the entrance channel properties, such as mass asymmetry, deformation of interacting nuclei, collision energy, and the Coulomb factor Z1 Z2. Any sudden change in the width of the mass distribution would indicate departure from full equilibration, while onset of mass asymmetry or a sudden increase in width would be a strong signal of quasi fission

  7. Gaussian quantum steering and its asymmetry in curved spacetime

    2016-06-01

    We study Gaussian quantum steering and its asymmetry in the background of a Schwarzschild black hole. We present a Gaussian channel description of quantum state evolution under the influence of Hawking radiation. We find that thermal noise introduced by the Hawking effect will destroy the steerability between an inertial observer Alice and an accelerated observer Bob who hovers outside the event horizon, while it generates steerability between Bob and a hypothetical observer anti-Bob inside the event horizon. Unlike entanglement behaviors in curved spacetime, here the steering from Alice to Bob suffers from a "sudden death" and the steering from anti-Bob to Bob experiences a "sudden birth" with increasing Hawking temperature. We also find that the Gaussian steering is always asymmetric and the maximum steering asymmetry cannot exceed ln 2 , which means the state never evolves to an extremal asymmetry state. Furthermore, we obtain the parameter settings that maximize steering asymmetry and find that (i) s =arccosh cosh/2r 1 -sinh2r is the critical point of steering asymmetry and (ii) the attainment of maximal steering asymmetry indicates the transition between one-way steerability and both-way steerability for the two-mode Gaussian state under the influence of Hawking radiation.

  8. Symmetry and Asymmetry in Bouncing Gaits

    Directory of Open Access Journals (Sweden)

    Giovanni A. Cavagna

    2010-06-01

    Full Text Available In running, hopping and trotting gaits, the center of mass of the body oscillates each step below and above an equilibrium position where the vertical force on the ground equals body weight. In trotting and low speed human running, the average vertical acceleration of the center of mass during the lower part of the oscillation equals that of the upper part, the duration of the lower part equals that of the upper part and the step frequency equals the resonant frequency of the bouncing system: we define this as on-offground symmetric rebound. In hopping and high speed human running, the average vertical acceleration of the center of mass during the lower part of the oscillation exceeds that of the upper part, the duration of the upper part exceeds that of the lower part and the step frequency is lower than the resonant frequency of the bouncing system: we define this as on-off-ground asymmetric rebound. Here we examine the physical and physiological constraints resulting in this on-off-ground symmetry and asymmetry of the rebound. Furthermore, the average force exerted during the brake when the body decelerates downwards and forwards is greater than that exerted during the push when the body is reaccelerated upwards and forwards. This landing-takeoff asymmetry, which would be nil in the elastic rebound of the symmetric spring-mass model for running and hopping, suggests a less efficient elastic energy storage and recovery during the bouncing step. During hopping, running and trotting the landing-takeoff asymmetry and the mass-specific vertical stiffness are smaller in larger animals than in the smaller animals suggesting a more efficient rebound in larger animals.

  9. Measurements of the Top Anti-Top Production Cross Section and Top Quark Mass in the Hadronically Decaying Tau + Jets Decay Channel at CDF

    Energy Technology Data Exchange (ETDEWEB)

    Hare, Daryl Curtis [Rutgers Univ., Piscataway, NJ (United States)

    2011-01-01

    In this thesis, we present the first exclusive observation of the t-t → hadronic τ + jets decay channel. Using these events, we measure the t-t pair production cross section and the top quark mass in 2.2 fb-1 of data collected with the Collider Detector at Fermilab (CDF). The Tevatron accelerator at Fermilab provides collisions of protons and anti-protons at a center-of-mass energy of √s = 1.96 TeV and is one of only two accelerators in the world with enough energy to produce top quarks. With a branching fraction of nearly 10%, the hadronic τ + jets decay channel is the third largest t-t decay mode, and it has only been minimally explored. This the first measurement of the t-t pair production cross section in this decay channel at CDF and the first measurement of the top quark mass in this decay channel in the world. The analysis introduces a new method to recover the total momentum of the ν produced in the τ decay and an artificial neural network to reduce the contribution from the largest background source, QCD multijet background. The t-t pair production cross section is extracted by minimizing a negative log likelihood function which compares the number of observed events to the number of expected events for a given t-t cross section. The top quark mass is extracted by minimizing a negative log likelihood function built from signal and ii background probabilities which are based on the matrix elements for t-t production and decay and W + 4 parton production, respectively. Using events selected with exactly 1 hadronically decaying τ, exactly 4 jets with at least 1 identified as having originated from a b quark, and large missing transverse energy, we measure the t-t pair production cross section to be 8.8 ± 3.3 (stat.) ± 2.2 (syst.) pb and the top quark mass to be 172.7±9.3 (stat.) ±3.7 (syst.) GeV. We find both values to be in good agreement with

  10. Final Results on Electroweak Asymmetries from SLD

    International Nuclear Information System (INIS)

    I present the final measurements of the Z boson-lepton coupling asymmetry parameters Ae, Aμ, and Aτ, obtained from the complete sample of polarized Z bosons collected by the SLD detector at the SLAC Linear Collider. The measurements use leptonic Z decays and the results are Ae = 0.1544 ± 0.0060, Aμ = 0.142 ± 0.015, and Aτ = 0.136 ± 0.015. The Ae result is combined with the left-right asymmetry using Z decays to hadrons, ALR0 (''' Ae), and is found to be Ae = 0.1516 ± 0.0021. Assuming lepton universality, a combined effective weak mixing angle of sin2 θWeff = 0.23098 ± 0.00026 is obtained. Using additional Standard-Model parameters an upper limit on the Higgs mass is given

  11. Matter-antimatter asymmetry

    2002-07-01

    The Conference is devoted to a multidisciplinary study of matter-antimatter asymmetry and, in particular, from the point of view of particle physics, astrophysics and cosmology. A number of topics, such as the practical applications of antimatter in medical imaging, of particular interest to non-specialists, will also be briefly covered. More than thirty years after the discovery of CP violation in the kaon system, precision experiments with kaons at CERN and Fermilab have demonstrated the existence of direct CP violation, opening a window on a hitherto poorly explored part of particle physics. On the one hand, two experiments devoted mainly to CP violation in B mesons, BABAR and Belle, are beginning to test CP violation in the Standard Model in a decisive way. On the other hand, balloon experiments and the space-based AMS project are circumscribing precise limits on the cosmological abundance of antimatter. Finally, the fundamental problem of cosmological matter-antimatter asymmetry at a Grand Unification scale or at the Electroweak phase transition has been the object of intense theoretical activity in recent years. This document gathers most of the slides that have been presented in the plenary and parallel sessions.

    2016-01-01

    The top-quark mass is measured in the all-hadronic top-antitop quark decay channel using proton--proton collisions at a centre-of-mass energy of sqrt(s )= 8 TeV with the ATLAS detector at the CERN Large Hadron Collider. The data set used in the analysis corresponds to an integrated luminosity of 20.2 fb-1. The analysis is performed on events containing at least six jets, at least two of which must be originating from b-quarks. The reconstruction of the top quark pair and the W bosons in each event is performed using a chi^2 method. The large QCD multi-jet background is modelled using a data-driven method. The top-quark mass is obtained from template fits to the ratio of the three-jet to the dijet mass. The three-jet mass is obtained from the three jets assigned to the top quark decay. From these three jets the dijet mass is obtained using the two jets assigned to the W boson decay. The top-quark mass is measured to be 173.80 +/- 0.55 (stat.) +/- 1.01 (syst.) GeV.

    A first measurement of the top quark spin asymmetry, sensitive to the top quark polarisation, in $t$-channel single top quark production is presented. It is based on a sample of pp collisions at a centre-of-mass energy of 8 TeV corresponding to an integrated luminosity of 19.7 fb$^{-1}$. A high-purity sample of $t$-channel single top quark events with an isolated muon is selected. Signal and background components are estimated using a fit to data. A differential cross section measurement, corrected for detector effects, of an angular observable sensitive to the top quark polarisation is performed. The differential distribution is used to extract a top quark spin asymmetry of 0.26 $\\pm$ 0.03 (stat) $\\pm$ 0.10 (syst), which is compatible with a $p$-value of 4.6% with the standard model prediction of 0.44.

The differential distribution is used to extract a top quark spin asymmetry of 0.26 ± 0.03 (stat) ± 0.10 (syst), which is compatible with a p-value of 4.6% with the standard model prediction of 0.44.

    The potential of the LHC for investigation of anomalous top quark interactions with gluon ($tug,tcg$) through the production of $tW$-channel of single top quark is studied. In the Standard Model, the single top quarks in the $tW$-channel mode are charge symmetric meaning that $\\sigma(pp\\to t+W^{-}) = \\sigma(pp\\to \\bar{t}+W^{+})$. However, the presence of anomalous FCNC couplings leads to charge asymmetry. In this paper a method is proposed in which this charge asymmetry may be used to constrain anomalous FCNC couplings. The strength of resulting constraints is estimated for the LHC for the center of mass energies of 7 and 14 TeV.

    The top quark mass is measured in the $t\\bar{t}\\to\\mbox{dilepton}$ channel ($\\mbox{lepton}=e, \\mu$) using ATLAS data recorded in the year 2012 at the LHC. The data were taken at a proton--proton centre-of-mass energy of $\\sqrt{s}=8$ TeV and correspond to an integrated luminosity of about 20.2fb$^{-1}$. Exploiting the template method, and using the distribution of invariant masses of lepton--b-jet pairs, the top quark mass is measured to be $m_{\\mathrm{top}} = 172.99 \\pm 0.41 \\mathrm{(stat)} \\pm 0.74 \\mathrm{(syst)}$ GeV, with a total uncertainty of 0.84 GeV. Finally, a combination with previous ATLAS $m_{\\mathrm{top}}$ measurements from $\\sqrt{s}=7$ TeV data in the $t\\bar{t}\\to\\mbox{dilepton}$ and $t\\bar{t}\\to\\mbox{lepton+jets}$ channels results in $m_{\\mathrm{top}}=172.84 \\pm 0.34 \\mathrm{(stat)} \\pm 0.61 \\mathrm{(syst)}$ GeV, with a total uncertainty of 0.70 GeV.

  17. Calculations of asymmetries in electron-alkali scattering

    International Nuclear Information System (INIS)

    In this work it is shown that in order to calculate spin asymmetries at projectile energies above the ionization threshold, the target continuum needs to be taken into account. However, this does not imply that in the experiment, intermediate excitation into the continuum plays a major role. Rather, any theory, such as the standard close-coupling method, that does not allow for electron flux to be in all open channels is likely to have difficulty in reproducing the measured spin asymmetries. 30 refs., 2 figs

    Torticollis can arise from nonocular (usually musculoskeletal) and ocular conditions. Some facial asymmetries are correlated with a history of early onset ocular torticollis supported by the presence of torticollis on reviewing childhood photographs. When present in an adult, this type of facial asymmetry with an origin of ocular torticollis should help to confirm the chronicity of the defect and prevent unnecessary neurologic evaluation in patients with an uncertain history. Assessment of facial asymmetry consists of a patient history, physical examination, and medical imaging. Medical imaging and facial morphometry are helpful for objective diagnosis and measurement of the facial asymmetry, as well as for treatment planning. The facial asymmetry in congenital superior oblique palsy is typically manifested by midfacial hemihypoplasia on the side opposite the palsied muscle, with deviation of the nose and mouth toward the hypoplastic side. Correcting torticollis through strabismus surgery before a critical developmental age may prevent the development of irreversible facial asymmetry. Mild facial asymmetry associated with congenital torticollis has been reported to resolve with continued growth after early surgery, but if asymmetry is severe or is not treated in the appropriate time, it might remain even with continued growth after surgery.

    We study Gaussian quantum steering and its asymmetry in the background of a Schwarzschild black hole. We present a Gaussian channel description of quantum state evolution under the influence of Hawking radiation. We find that thermal noise introduced by Hawking effect will destroy the steerability between an inertial observer Alice and an accelerated observer Bob who hovers outside an event horizon, while it generates steerability between Bob and a hypothetical observer Anti-Bob inside the event horizon. Besides, unlike entanglement behaviors in curved spacetime, here the steering from Alice to Bob suffers from a ``sudden death" and the steering from Anti-Bob to Bob appears a ``sudden birth" with the increasing of Hawking temperature. We also find that the Gaussian steering is always asymmetric and the maximum steering asymmetry can \\emph{ exceed} $\\ln 2$ in curved spacetime, which is quite different from the flat spacetime case [Phys. Rev. Lett. 114, 060403 (2015)] where the steering asymmetry can \\emph{neve...

  20. L-R asymmetry in gut's

    International Nuclear Information System (INIS)

    An idea of L-R asymmetry is proposed for the grand unification schemes. The idea provides an intrinsic mechanism to obtain standard model charges of fermions in the case of more than one weak gauge boson. It is elaborated within a scheme based on the partial symmetry SU(4)sub(C)xSU(2)sub(L)xSU(2)sub(R) where the coupling constants gsub(L) and gsub(R) corresponding to the chiral SU(2) factors are assumed to be different from each other. Then, the embedding of this structure within the simple symmetry SO(10) is shown. In both cases, a consistent description of vector particle masses is given. These two schemes are considered as primary models to realize the L-R asymmetry idea due to the lack of family unification. However, in a subsequent work, we will show that the SO(14) unification of the three families can be obtained within the framework of L-R asymmetry. All formulations are carried out with the aid of a mathematical method that we recently proposed for the Lie algebra representations of classical groups. (author)

  1. Hemispheric and longitudinal asymmetries in CME occurrence

    International Nuclear Information System (INIS)

    Complete text of publication follows. A considerable amount of evidence has accumulated in support of the existence of persistent, systematic north-south (hemispherical) and longitudinal (active longitudes) asymmetries in the Sun. These features have been observed, e.g., in sunspots, solar flares, solar wind and the heliospheric magnetic field. In this work we analyze the occurrence of Coronal Mass Ejections (CMEs) observed by the SOHO LASCO instrument during the solar cycle 23. We use the manually compiled LASCO CME catalog maintained at the CDAW Data Center and for comparison the CACTus CME catalog based on automatic detection of CMEs by the CACTus software developed at SIDC in the Royal Observatory of Belgium. We discuss the temporal evolution of the occurrence rate of CMEs and study the north-south and east-west asymmetries and their temporal change. We also present a preliminary analysis of CME occurrence in a rotating coordinate system. We discuss the observations in view of the earlier evidence for hemispherical asymmetries and active longitudes.

  2. Shell correction energy and the entrance channel effect on the formation of superheavy nuclei

    International Nuclear Information System (INIS)

    Based on the improved isospin dependent molecular dynamics model in which the shell correction energy of the system is calculated by using deformed two-center shell model and the surface energy of the system is improved by introducing a switch function that combines the surface energies of projectile and target with the one of the compound nucleus. The effects of the shell correction energy on synthesis of superheavy nuclei and the fusion cross sections in asymmetric and nearly symmetric reaction systems leading to the same compound nuclei 62Zn, 76Kr, and 202Pb are studied. The entrance channel mass asymmetry dependence of compound nucleus formation is found by analyzing the shell correction energies, Coulomb barriers and fusion cross sections. The experimental data are described quantitatively by the present model. It is found that the compound nucleus formation is favorable for the systems with larger mass asymmetry. (author)

    The purpose of present investigation is to study the Hall and MHD effects on peristaltic flow of Carreau-Yasuda fluid in a convectively curved configuration. Thermal radiation, Soret and Dufour effects are also accounted. The channel walls comprised the no slip and compliant properties. Constitutive equations for mass, momentum, energy and concentration are first modeled in view of considered assumptions and then simplified under long wavelength and low Reynolds number approximation. Solution of the resulting system of equations is carried out via a regular perturbation technique. Physical behaviors of velocity, temperature, concentration and streamlines are discussed with the help of graphical representation.

    Full Text Available This paper is devoted to the study of the peristaltic motion of non-Newtonian fluid with heat and mass transfer through a porous medium in the channel under the effect of magnetic field. A modified Casson non-Newtonian constitutive model is employed for the transport fluid. A perturbation series’ method of solution of the stream function is discussed. The effects of various parameters of interest such as the magnetic parameter, Casson parameter, and permeability parameter on the velocity, pressure rise, temperature, and concentration are discussed and illustrated graphically through a set of figures.

  5. Quantifying asymmetry: ratios and alternatives.

    Traditionally, the study of metric skeletal asymmetry has relied largely on univariate analyses, utilizing ratio transformations when the goal is comparing asymmetries in skeletal elements or populations of dissimilar dimensions. Under this approach, raw asymmetries are divided by a size marker, such as a bilateral average, in an attempt to produce size-free asymmetry indices. Henceforth, this will be referred to as "controlling for size" (see Smith: Curr Anthropol 46 (2005) 249-273). Ratios obtained in this manner often require further transformations to interpret the meaning and sources of asymmetry. This model frequently ignores the fundamental assumption of ratios: the relationship between the variables entered in the ratio must be isometric. Violations of this assumption can obscure existing asymmetries and render spurious results. In this study, we examined the performance of the classic indices in detecting and portraying the asymmetry patterns in four human appendicular bones and explored potential methodological alternatives. Examination of the ratio model revealed that it does not fulfill its intended goals in the bones examined, as the numerator and denominator are independent in all cases. The ratios also introduced strong biases in the comparisons between different elements and variables, generating spurious asymmetry patterns. Multivariate analyses strongly suggest that any transformation to control for overall size or variable range must be conducted before, rather than after, calculating the asymmetries. A combination of exploratory multivariate techniques, such as Principal Components Analysis, and confirmatory linear methods, such as regression and analysis of covariance, appear as a promising and powerful alternative to the use of ratios.

    The LHCb experiment observed B+ --> pi+ mu+ mu- decay with 1.0 fb^-1 data, which is the first measurement of a flavor changing neutral current b --> d l+ l- decay (l = e, mu). Based on QCD factorization, we give Standard Model predictions for the branching ratios, direct CP asymmetries, and isospin asymmetry for B --> pi l+ l- decays, in the kinematic region where the dilepton invariant mass is small. We find that the contribution from weak annihilation enhances the direct CP asymmetry for low l+ l- pair mass. Anticipating improved measurements, we assess the utility of B+ --> pi+ l+ l- observables, when combined with B0 --> pi- l+ nu and B+ --> K+ l+ l-, for determining CKM parameters in the future.

    A measurement of the top-quark mass is presented using Tevatron data from proton-antiproton collisions at center-of-mass energy $\\sqrt{s}=1.96$ TeV collected with the CDF II detector. Events are selected from a sample of candidates for production of $t\\bar t$ pairs that decay into the lepton+jets channel. The top-quark mass is measured with an unbinned maximum likelihood method where the event probability density functions are calculated using signal and background matrix elements, as well as a set of parameterized jet-to-parton transfer functions. The likelihood function is maximized with respect to the top-quark mass, the signal fraction in the sample, and a correction to the jet energy scale (JES) calibration of the calorimeter jets. The simultaneous measurement of the JES correction ($\\JES$) amounts to an additional \\textit{in situ} jet energy calibration based on the known mass of the hadronically decaying $W$ boson. Using the data sample of 578 lepton+jets candidate events, corresponding to 3.2 $fb^{-1}...

  8. Measurement of the Double Spin Asymmetry in {pi}{sup -} Electroproduction with CLAS

    The double spin asymmetry {sigma}{sub et}/{sigma}{sub 0} has been measured in {pi}{sup -} electro-production using a polarized electron beam and a polarized ND{sub 3} target, and using a CEBAF Large Acceptance Spectrometer (CLAS). The electron beam was polarized using a GaAs-cathode and the target was polarized via Dynamic Nuclear Polarization. The beam polarization was around 70% and the target polarization was between 10 and 20 percent. The data at 2.5 GeV beam energy and two different magnetic field settings (2250 A and -1500 A) were collected in Hall B at Jefferson Lab in the Fall of 1998. The e{pi}{sup -} channel was selected using the missing mass technique and applying a cut around the proton peak (0.78 GeV{sup 2} < MM{sup 2} < 0.95 GeV{sup 2}). The asymmetry (A{sub 1} + {eta}A{sub 2})/(1+{epsilon}R), where both A{sub 1} and A{sub 2} depend on {theta}*, has been extracted as a function of the invariant mass W for two Q{sup 2} (four-momentum-transfer-squared) bins (0.08 GeV{sup 2} < Q{sup 2} < 0.4 GeV{sup 2} and 0.4 GeV{sup 2} < Q{sup 2} < 1.2 GeV{sup 2}). The results were integrated over the angular acceptance of the channel as well as for a narrower range in {theta}* (0.17 < cos{theta}* < 1). The data have been compared to two phenomenological models, MAID and AO.

  9. Analysis of some mass and momentum transfer correlations applicability in an adiabatic model of flooding of a reactor channel

    International Nuclear Information System (INIS)

    In this paper an analysis of the applicability of entrainment inception, entrainment rate and interfacial friction correlation in case of counter current annular flow and flooding in a reactor channel has been performed. The thermo-hydraulic model formulation consists of separate treatment of the liquid film and gas droplet mixture in the channel core, while droplet phase of the gas-droplet mixture has been treated with drift-flux model. The results of the analysis have been compared and verified with the correspondingly selected experimental data. In this paper some modifications of the before mentioned correlations in the model have been suggested to achieve better agreement of the results with the experimental data. (author)

  10. Steady Free Convection and Mass Transfer MHD Flow of a Micropolar Fluid in a Vertical Channel with Heat Source and Chemical Reaction

    2014-10-01

    Full Text Available This paper reports a numerical study of steady free convection and mass transfer flow of a conducting micropolar fluid between two vertical walls in the presence of temperature dependent heat source/sink and chemical reaction under the influence of a transverse magnetic field. The numerical solution of the governing differential equations are obtained by using a fourth-order Runge-Kutta method along with the shooting technique for a wide range of emerging parameters. A striking result is to note that microrotation is independent of the material property and vortex viscosity in the middle layers of the channel. The conformity of the findings of the present study is in good agreement with the results reported earlier in the absence of mass transfer associated with a chemical reaction.

    The dreams of 103 children and adolescents, aged 10-17 years, have been studied. The test group included 78 patients with neurotic disorders; control one consisted of 25 healthy subjects. Dream features, which were common for those with preferentially left asymmetry profile both in patients as well as in healthy subjects, were: less expressed novelty factor and frequent appearance of rare phenomena, such as "déjà vu in wakefulness", reality, "mixed" (overlapped) dreams, prolonged dreams in repeat sleep, frequent changes of personages and scenes of action. Left-hander dream peculiarities, being detected only in neurotic patients but not in healthy subjects, emerged as lucid phenomena deficit, "dream in dreams" and "dream reminiscence in dream" syndrome, which have been found only in left-handers. Right and left hemispheres seem to contribute in different ways to a dream formation. In authors believe that the left hemisphere seems to provide dream origin while the right hemisphere provides dream vividness, figurativeness and affective activation level. PMID:11811128

  12. Hemispheric asymmetries: The comparative view

    Full Text Available Hemispheric asymmetries play an important role in almost all cognitive functions. For more than a century, they were considered to be uniquely human but now an increasing number of findings in all vertebrate classes make it likely that we inherited our asymmetries from common ancestors. Thus, studying animal models could provide unique insights into the mechanisms of lateralization. We outline three such avenues of research by providing an overview of experiments on left-right differences in the connectivity of sensory systems, the embryonic determinants of brain asymmetries, and the genetics of lateralization. All these lines of studies could provide a wealth of insights into our own asymmetries that should and will be exploited by future analyses.

    Little is known about the genetic nature of human psychometric intelligence (IQ), but it is widely assumed that IQ's heritability is at loci for intelligence per se. We present evidence consistent with a hypothesis that interindividual IQ differences are partly due to heritable vulnerabilities to environmental sources of developmental stress, an indirect genetic mechanism for the heritability of IQ.

    Reasonably large relic neutrino asymmetries can be generated by active-sterile neutrino oscillations. After briefly discussing possible applications, I describe the Quantum Kinetic Equation formalism used to compute the asymmetry growth curves. I then show how the basic features of these curves can be understood on the basis of the adiabatic limit approximation in the collision dominated epoch, and the pure MSW effect at lower temperatures.

    The first measurement of the top-antitop production cross section in proton-antiproton collisions at {radical}s = 1.96 TeV using 243 pb{sup -1} of data collected with the D0 detector at Fermilab is presented. In this analysis, only the dielectron final state is considered. Five events are observed, and 0.93 background events are expected. The measured cross section, after accounting for the expected branching ratio to the dielectron channel, is {sigma}{sub t{bar t}} = 14.9{sub -7.0}{sup +9.4}(stat){sub -1.8}{sup +2.5}(syst) {+-} 1.0 (lumi) pb, which agrees with the predicted cross section for top quarks with a mass of 175 GeV. In addition, a first-pass at a measurement of the top mass using the neutrino-weighting method is presented. This measurement is also performed in the dielectron channel using the five events observed in the cross section measurement.

    Fallout radionuclides and their ratios, such as beryllium-7 (7Be) and lead-210 (210Pb), are used to determine suspended sediment source and age in catchments. The ratio of beryllium-7 to lead-210 (7Be/210Pb) on suspended sediment has been used to estimate the fraction of "new" sediment in suspension. In the application of this model, "new" suspended sediment is often assumed to originate from recent landscape surface erosion that is delivered to the stream network. Fallout radionuclide deposition can vary across watersheds and on an event basis in a single watershed due to factors such as storm type, atmospheric height, and storm origin. In the White Clay Creek watershed within the mid-Atlantic USA, single-event deposition of 7Be varies from 15 - 177 Bq m-2 and 210Pb varies from 0 - 10 Bq m-2. 7Be/210Pb ratios vary from 7.9 to 17 within event precipitation and from 0.8 to 12.8 on suspended sediment. "New" sediment varies from 6 - 100% over the course of these events. 7Be mass balance during events shows that the majority of 7Be is retained within the catchment and not exported on suspended sediment. During summer thunderstorms, less than 1% of 7Be deposited on the watershed exits the stream channel. By comparing this flux with the direct channel interception of 7Be deposition in precipitation and throughfall we can determine the minimum amount of 7Be leaving the watershed that could occur in the absence of surface erosion. For example in summer thunderstorms, the entirety of the 7Be exiting the watershed on suspended sediment is less than the total activity deposited on the channel in direct precipitation. Channel-intercepted fallout radionuclides can exit the catchment by multiple mechanisms including the tagging of subaerial fluvial deposits with event precipitation; hence "new" suspended sediment originates from within the channel rather than from surface erosion. During extreme events, such as Hurricane Irene, less of the suspended sediment has been newly

    2010-10-01

    This dissertation describes a measurement of the mass of the top quark using a method developed by G. Goldstein and R.H. Dalitz. It is based on 2.0 fb{sup -1} of data collected by the Collider Detector Facility at Fermi National Accelerator Laboratories. Di-lepton events were observed from colliding protons with anti-protons with {radical}s = 1.96 TeV in the Tevatron Collider. A total of 145 candidate events were observed with 49 expected to be from background. These events include two neutrinos which elude detection. The method begins by assuming an initial top quark mass and solves for the neutrino momenta using a geometrical construction. The method samples over a range of likely top quark masses choosing the most consistent mass via a likelihood function. An important distinguishing feature of this method from others is its lack of dependence on the missing transverse energy, a quantity that is poorly measured by the experiment. This analysis determines the top quark mass to be M{sub top} = 172.3 {+-} 3.4(stat.) {+-} 2.0(syst.) GeV/c{sup 2} (M{sub top} = 170.5 {+-} 3.7(stat.) {+-} 1.8(syst.) GeV/c{sup 2} with b-tagging).

  2. Entrance channel effect in the incomplete fusion reactions

    International Nuclear Information System (INIS)

    In the present work the effect of various entrance channel parameters on incomplete fusion strength and the reaction dynamics in 12C+159Tb system at energies ∼ 4-7 MeV/A have been investigated by measuring the excitation functions of individual reaction channels. Experimental excitation functions have been analyzed in the framework of compound nucleus decay using statistical model code PACE4. Analysis of data suggests the production of xn/pxn-channels via complete fusion of 12C with 159Tb, as these are found to be well reproduced by PACE4 predictions, while, a significant enhancement in the excitation functions of α-emitting channels has been observed over the theoretical ones. This enhancement has been attributed due to incomplete fusion. For better insight into the underlying dynamics, the fraction of incomplete fusion to the total fusion has been deduced and compared with 16O+159Tb and other nearby systems as a function of various entrance channel parameters. The fraction of incomplete fusion has been found to be sensitive to the projectile type, energy and entrance-channel mass-asymmetry. (authors)

  4. Measurement of the top quark mass in the dilepton channel using the neutrino weighting algorithm at CDF II

    Sabik, Simon

    We measure the top quark mass using approximately 359 pb-1 of data from pp¯ collisions at s = 1.96 GeV at CDF Run II. We select tt¯ candidates that are consistent with two W bosons decaying to a charged lepton and a neutrino following tt¯ → W+W-bb¯ → l+l- nn¯ bb¯. Only one of the two charged leptons is required to be identified as an electron or a muon candidate, while the other is simply a well measured track. We use a neutrino weighting algorithm which weighs each possibility of neutrino direction to reconstruct a top quark mass in each event. We compare the resulting distribution to Monte Carlo templates to obtain a top quark mass of 170.8+6.9-6.5 (stat) +/- 4.6 (syst) GeV/c 2.

    The top-quark mass M_top is measured using top quark-antiquark pairs produced in proton-antiproton collisions at a center-of-mass energy of 1.96 TeV and decaying into a fully hadronic final state. The full data set collected with the CDFII detector at the Fermilab Tevatron Collider, corresponding to an integrated luminosity of 9.3 fb-1, is used. Events are selected that have six to eight jets, at least one of which is identified as having originated from a b quark. In addition, a multivariate algorithm, containing multiple kinematic variables as inputs, is used to discriminate signal events from background events due to the strong interaction. Templates for the reconstructed top-quark mass are combined in a likelihood fit to measure M_top with a simultaneous calibration of the jet-energy scale. A value of M_top = 175.07+- 1.19(stat)+1.55-1.58(syst) GeV/c^2 is obtained for the top-quark mass.

    2012-01-01

    We use a global pixel based estimator to identify the axis of the residual Maximum Temperature Asymmetry (MTA) (after the dipole subtraction) of the WMAP 7 year Internal Linear Combination (ILC) CMB temperature sky map. The estimator is based on considering the temperature differences between opposite pixels in the sky at various angular resolutions (4 degrees-15 degrees and selecting the axis that maximizes this difference. We consider three large scale Healpix resolutions (N_{side}=16 (3.7 degrees), N_{side}=8 (7.3 degrees) and N_{side}=4 (14.7 degrees)). We compare the direction and magnitude of this asymmetry with three other cosmic asymmetry axes (\\alpha dipole, Dark Energy Dipole and Dark Flow) and find that the four asymmetry axes are abnormally close to each other. We compare the observed MTA axis with the corresponding MTA axes of 10^4 Gaussian isotropic simulated ILC maps (based on LCDM).

    The dominant contributions to W∓H± production at the LHC are the tree-level bb¯ annihilation and the gg fusion. We perform for the case of the complex minimal supersymmetric standard model (MSSM) a complete calculation of the next-to-leading order (NLO) electroweak corrections to the bb¯ annihilation channel and a consistent combination with other contributions including the standard and supersymmetric-QCD (SUSY-QCD) corrections and the gg fusion, with resummation of the leading radiative corrections to the bottom-Higgs couplings and the neutral Higgs boson propagators. We observe a large CP-violating asymmetry, arising mainly from the gg channel.

    Full Text Available Abstract Background Trunk asymmetry (TA is a common phenomenon in children, but its incidence in juveniles is not known. The present cross sectional study reports TA in normal juveniles and provides data which describe the evolution of TA from early childhood to adolescence. Materials and methods The scoliometer readings in both standing and sitting forward bending position (FBP of 3301 children, (1645 boys, and 1656 girls aged from 3 to 9 years old were studied. TA was quantified by measuring angle of trunk rotation (ATR and children were categorized as symmetric (ATR = 0°, mild asymmetric (ATR 1° – 6° and severely asymmetric (ATR ≥ 7°. The difference of TA between standing and sitting FBP as well as differences between boys and girls in frequency of TA were also calculated. The scoliometer readings were analyzed by age to reveal at which age the juvenile pattern of TA changes into the adolescent one. Results 74.2% of boys and 77% of girls were symmetric (ATR = 0° in the thoracic region in standing FBP, while 82.7% of boys and 84.1% of girls were symmetric in the thoracic region in sitting FBP. Juvenile girls are more symmetric than boys but severe TA was found almost the same between the two genders. A significant reduction in the frequency of mild TA from standing into sitting FBP, in all the examined regions in both boys and girls was found, but in severe TA this reduction is very small. Analysing scoliometer readings by age it appears that significant TA changes take place between 8–9 years of age for boys and between 6–7 and 8–9 years for girls. TA in boys is changing into the adolescent pattern at a later age than in girls. Conclusion Juveniles were found more symmetric than adolescents, who were studied previously in a different study. Furthermore, juvenile girls were found more symmetric than boys. Juvenile TA pattern seems to be in accordance with the higher incidence of juvenile idiopathic scoliosis in boys. Furthermore

  9. On development of analytical closure relationships for local wall friction, heat and mass transfer coefficients for sub-channel codes

    International Nuclear Information System (INIS)

    The purpose has been to describe an approach suggested for constructing generalized closure relationships for local and subchannel wall friction, heat and mass transfer coefficients, with not only axial and transversal parameters taken into account, but azimuthal substance transfer effects as well. These constitutive relations that are primary for description of one- and two-phase one-dimensional flow models can be derived from the initial 3-D drift flux formulation. The approach is based on the Reynolds flux, boundary layer and generalized coefficient of substance transfer. One more task has been to illustrate the validity of the 'conformity principle' for the limiting cases. The method proposed is based on the similarity theory, boundary layer model, and a phenomenological description of the regularities of the substance transfer (momentum, heat, and mass), as well as on an adequate simulation of the forms of flow structure by a generalized approach to build (an integrated in form and semi-empirical in maintenance structure) analytical relationships for wall friction, heat and mass transfer coefficients.

  10. Top-quark mass measurement in the tt-bar-dilepton channel using the full CDF Run II data set

    International Nuclear Information System (INIS)

    We present a measurement of the top-quark mass with tt-bar-dilepton events using the full CDF Run II data set, which corresponds to an integrated luminosity of 9.1 fb-1 collected from √s = 1.96 TeV pp-bar collisions at the Fermilab Tevatron. A sample of 520 events is obtained after all selection requirements. The top-quark mass is estimated by a fit of the distribution of some variable to a sum of signal and background contributions. This variable is defined using special approach to reduce the systematic error due to the jet energy scale uncertainty. Templates are built from simulated tt-bar and background events, and parameterized in order to provide probability distribution functions. A likelihood fit of the data returns the top-quark mass of (170.80∓1.83 (stat.)∓2.69 (syst.)) GeV/c2 (or (170.80∓3.25) GeV/c2).

  12. Baryomorphosis: Relating the Baryon Asymmetry to the "WIMP Miracle"

    CERN Document Server

    McDonald, John

    2010-01-01

    We present a generic framework, "baryomorphosis", which modifies the baryon asymmetry to be naturally of the order of a typical thermal relic WIMP density. We consider a simple scalar-based model to show how this is possible. This model introduces a sector in which a large initial baryon asymmetry is injected into particles ("annihilons"), phi_{B}, phi_{B, hat}, of mass ~ 100 GeV - 1 TeV. phi_{B}-phi_{B, hat} annihilations convert the initial phi_{B}, phi_{B, hat} asymmetry to a final asymmetry with a thermal relic WIMP-like density. This subsequently decays to a conventional baryon asymmetry whose magnitude is naturally related to the density of thermal relic WIMP dark matter. In this way the two coincidences of baryons and dark matter i.e. why their densities are similar to each other and why they are both similar to a WIMP thermal relic density (the "WIMP miracle"), may be understood. The model can be tested by the production of annihilons at colliders.

    We explore the hemispherical asymmetry predicted in cosmic microwave background polarization when there is an asymmetry in temperature anisotropies due to primordial perturbations. We consider the cases of asymmetries due to adiabatic and isocurvature modes, and tensor perturbations. We show that the asymmetry in the TE, EE and/or BB correlations can be substantially larger than those in the TT power spectrum in certain cases. The relative asymmetry in the different cross-correlations, as well as the angular scale dependence, can in principle distinguish between different origins for the asymmetry.

  14. Search for a High Mass Higgs Boson in the Channel H - ZZ - llbb and digital filtering for the ATLAS level-1 calorimeter trigger

    CERN Document Server

    Hadley, David Richard; Thompson, Paul

    The Standard Model of particle physics predicts the existence of a new massive state: the Higgs Boson. The discovery or exclusion of this particle is one of the main goals of the ATLAS experiment. One of the greatest experimental challenges at the LHC is to achieve efficient triggering. The ATLAS rst level calorimeter trigger uses reduced granularity information from the calorimeters to search for high ET e, y,t and jets as well as identifying high Emiss T and total ET events. A Finite Impulse Response (FIR) lter combined with a peak nder is applied to identify signals, determine their correct bunch-crossing and improve the energy measurement. A study to determine the optimum lter coecients is presented. The performance of these lters is investigated with commissioning data and cross-checks of the calibration with initial beam data are shown. In this thesis a study of the search sensitivity in the channel H - ZZ - llbb is presented. This channel can contribute to the Higgs search in the high mass region tha...

    We analyze the Sivers asymmetry in both Drell-Yan (DY) production and semi-inclusive deep inelastic scattering (SIDIS), while considering properly defined transverse momentum dependent parton distribution and fragmentation functions and their QCD evolution. After finding a universal non-perturbative spin-independent Sudakov factor that can describe reasonably well the world's data of SIDIS, DY lepton pair and $W/Z$ production in unpolarized scatterings, we perform a global fitting of all the experimental data on the Sivers asymmetry in SIDIS from HERMES, COMPASS and Jefferson Lab. Then we make predictions for the asymmetry in DY lepton pair and $W$ boson production, which could be compared to the future experimental data in order to test the sign change of the Sivers function.

  17. Autophoretic locomotion from geometric asymmetry

    CERN Document Server

    Michelin, Sebastien

    2015-01-01

    Among the few methods which have been proposed to create small-scale swimmers, those relying on self-phoretic mechanisms present an interesting design challenge in that chemical gradients are required to generate net propulsion. Building on recent work, we propose that asymmetries in geometry are sufficient to induce chemical gradients and swimming. We illustrate this idea using two different calculations. We first calculate exactly the self-propulsion speed of a system composed of two spheres of unequal sizes but identically chemically homogeneous. We then consider arbitrary, small-amplitude, shape deformations of a chemically-homogeneous sphere, and calculate asymptotically the self-propulsion velocity induced by the shape asymmetries. Our results demonstrate how geometric asymmetries can be tuned to induce large locomotion speeds without the need of chemical patterning.

  19. Two lunar global asymmetries

    1984-01-01

    The Moon's center of mass is displaced from its center of figure about 2 km in a roughly earthward direction. Most maria are on the side of the Moon which faces the Earth. It is assumed that the Moon was initially spherically symmetric. The emplacement of mare basalts transfers mass which produces most of the observed center of mass displacement toward the Earth. The cause of the asymmetric distribution of lunar maria was examined. The Moon is in a spin orbit coupled relationship with the Earth and the effect of the Earth's gravity on the Moon is asymmetric. The earth-facing side of the Moon is a gravitational favored location for the extrusion of mare basalt magma in the same way that the topographically lower floor of a large impact basin is a gravitationally favored location. This asymmetric effect increases inversely with the fourth power of the Earth Moon distance. The history of the Earth-Moon system includes: formation of the Moon by accretion processes in a heliocentric orbit ner that of the Earth; a gravitational encounter with the Earth about 4 billion years ago resulting in capture of the Moon into a geocentric orbit and heating of the Moon through dissipation of energy related to tides raised during close approaches to the Earth(5) to produce mare basalt magma; and evolution of the Moon's orbit to its present position, slowly at first to accommodate more than 500 million years during which magmas were extruded.

  20. In situ Gelation of Monodisperse Alginate Hydrogel in Microfluidic Channel Based on Mass Transfer of Calcium Ions

    International Nuclear Information System (INIS)

    A microfluidic method for the in situ production of monodispersed alginate hydrogels using biocompatible polymer gelation by crosslinker mass transfer is described. Gelation of the hydrogel was achieved in situ by the dispersed calcium ion in the microfluidic device. The capillary number (Ca) and the flow rate of the disperse phase which are important operating parameters mainly influenced the formation of three distinctive flow regions, such as dripping, jetting, and unstable dripping. Under the formation of dripping region, monodispersed alginate hydrogels having a narrow size distribution (C.V=2.71%) were produced in the microfluidic device and the size of the hydrogels, ranging from 30 to 60 µm, could be easily controlled by varying the flow rate, viscosity, and interfacial tension. This simple microfluidic method for the production of monodisperse alginate hydrogels shows strong potential for use in delivery systems of foods, cosmetics, inks, and drugs, and spherical alginate hydrogels which have biocompatibility will be applied to cell transplantation

  2. Search for high mass resonances in the dimuon channel using the muon spectrometer of the atlas experiment at CERN

    International Nuclear Information System (INIS)

    This thesis covers the search of new neutral gauge bosons decaying into a pair of muons in the ATLAS detector. The Large Hadron Collider (LHC) at CERN will produce parton collisions with very high center of mass energy and may produce Z' predicted by many theories beyond the standard model. Such a resonance should be detected by the ATLAS experiment. For the direct search of Z' decaying into two muons, a small number of events is enough for its discovery, which is possible with the first data. We shall study in particular the effects of the muon spectrometer alignment on high pT tracks and on the Z' discovery potential in the ATLAS experiment. The discovery potentials computed with this method have been officially approved by the ATLAS collaboration and published. At the start of the LHC operation, the muon spectrometer alignment will not have reached the nominal performances. This analysis aims at optimizing the discovery potential of ATLAS for a Z' boson in this degraded initial conditions. The impact on track reconstruction of a degraded alignment is estimated with simulated high pT tracks. Results are given in terms of reconstruction efficiency, momentum and invariant mass resolutions, charge identification and sensitivity to discovery or exclusion. With the first data, an analysis using only the muon spectrometer in stand alone mode will be very useful. Finally, a study on how to determine the initial geometry of the spectrometer (needed for its absolute alignment) is performed. This study uses straight tracks without a magnetic field and also calculates the beam time necessary for reaching a given accuracy of the alignment system. (author)

  3. Neighboring Galaxies' Influence on Rotation Curve Asymmetry

    2003-01-01

    The rotation velocity asymmetry v observed in spiral galaxy HI rotation curves linearly correlates with the effective potential force from the 10 closest neighboring galaxies normalized for the test particle mass and the gravitational constant. The magnitude of the potential force from a close galaxy is proportional to the luminosity of the close galaxy and inversely proportional to the square of the distance from the close galaxy to the target galaxy. The correlation coefficient is 0.99 and F test is 0.99. Also, the slope of the rotation curve in the disk region of a galaxy from rising to flat to declining is qualitatively correlated with increasing asymmetry and, hence, to the net force from other galaxies. The result is based on a sample of nine spiral galaxies with published Cepheid distances and rotation curves and with a wide range of characteristics. These relationships are interesting not only for their predictive power but also because (1) they suggest a galaxy's dynamics and the shape of its rotatio...

  4. Lepton asymmetry and the cosmic QCD transition

    International Nuclear Information System (INIS)

    We study the influence of lepton asymmetries on the evolution of the early Universe. The lepton asymmetry l is poorly constrained by observations and might be orders of magnitudes larger than the observed baryon asymmetry b ≅ 10−10, |l|/b ≤ 2 × 108. We find that lepton asymmetries that are large compared to the tiny baryon asymmetry, can influence the dynamics of the QCD phase transition significantly. The cosmic trajectory in the μB−T phase diagram of strongly interacting matter becomes a function of lepton (flavour) asymmetry. For tiny or vanishing baryon and lepton asymmetries lattice QCD simulations show that the cosmic QCD transition is a rapid crossover. However, for large lepton asymmetry, the order of the cosmic transition remains unknown

  5. Measurement of gluon polarization through spin asymmetry in the production of charmed mesons

    International Nuclear Information System (INIS)

    The main aim of the COMPASS experiment is the measurement of the gluon polarization in the nucleon, which can be accessed by the spin asymmetry in the scattering of a polarized muon beam on a polarized nucleon target. The process sensitive to the gluon polarization is the photon-gluon fusion, which can be tagged in the cleanest way by looking at the production of D0 mesons. At COMPASS, D0 mesons are reconstructed from the invariant mass of their decay products. However, it is a rare process, dominated by a large combinatorial background. This thesis presents some studies devoted to the improvement of the charmed mesons reconstruction. The measurement of the efficiency and the space resolution of the 3 drift chamber stations of the COMPASS spectrometer is a necessary step in understanding the performances of the reconstruction of particle trajectories. The hadron identification, which is fundamental in the reconstruction of charmed meson decay, is performed by a RICH detector. A statistical treatment of signal and background, together with an upgrade project to replace the present front-end electronics, have been developed in order to improve the particle identification performances. The second part of this work concerns the spin asymmetry measurement, which requires the application of event selection criteria in order to minimize the noise over signal ratio in the D0 invariant mass, and the development of event-weighting methods to reduce the statistical error. This work presents a preliminary result, based on 2002-2004 statistics, which is the ΔG/G measurement from open charm production. Although the error bars are large, the measured gluon polarization is compatible with zero. Given the present accuracy, this result is compatible with the existing direct measurements from other channels. However, it does not allow to distinguish between different theoretical models.

  10. Composite asymmetry as an indicator of quality in the beneficial wasp Trichogramma nr. brassicae (Hymenoptera: Trichogrammatidae).

    Hewa-Kapuge, S; Hoffmann, A A

    2001-08-01

    Trichogramma are egg parasitoids that are widely cultured for the control of moth pests in commercial insectaries. Stock quality is often maintained by releasing wasps from a mass culture in an area with target host eggs and initiating fresh stocks from parasitized eggs. Here we test if variability among individuals as measured by fluctuating asymmetry can be used as an additional method of quality control in Trichogramma nr. brassicae by comparing fluctuating asymmetry levels between a random sample of wasps before release and wasps that successfully reach host eggs. Although the asymmetry of individual traits was not associated with wasp fitness, a total asymmetry measure based on combining the uncorrelated asymmetries of nine traits did predict the ability of wasps to reach the eggs.

  11. On the Origin of System III Asymmetries in the Io Torus

    Schneider, N. M.; Delamere, P. A.

    2006-01-01

    The Io plasma torus exhibits several intriguing asymmetries which offer insights to the processes that transport mass and energy through the system. While these asymmetries are increasingly well described observationally, most still lack physical explanations. One important asymmetry is fixed in the coordinate system corotating with Jupiter's magnetic field. Space-based and ground-based observations have shown that torus ions are hotter and more highly ionized around System III 20 deg. Our simulations show that this type of torus asymmetry can be caused by enhanced pickup of fresh ions from Io's neutral clouds near these longitudes. The enhancement is caused primarily by the tilt and offset of the torus relative to the neutral clouds. We will report on the model parameters required to match the observed asymmetries, and offer predictions which will allow a test of this hypothesis.

    2013-01-01

    Using hourly station rain gauge data in the warm season (May-October) during 1961-2006,the climatological features of the evolution of the rainfall process are analyzed by compositing rainfall events centered on the maximum hourly rainfall amount of each event.The results reveal that the rainfall process is asymmetric,which means rainfall events usually reach the maximum in a short period and then experience a relatively longer retreat to the end of the event.The effects of rainfall intensity,duration and peak time,as well as topography,are also considered.It is found that the asymmetry is more obvious in rainfall events with strong intensity and over areas with complex terrain,such as the eastern margin of the Tibetan Plateau,the Hengduan Mountains,and the Yungui Plateau.The asymmetry in short-duration rainfall is more obvious than that in long-duration rainfall,but the regional differences are weaker.The rainfall events that reach the maximum during 14:00-02:00 LST exhibit the strongest asymmetry and those during 08:00-14:00 LST show the weakest asymmetry.The rainfall intensity at the peak time stands out,which means that the rainfall intensity increases and decreases quickly both before and after the peak.These results can improve understanding of the rainfall process and provide metrics for the evaluation of climate models.Moreover,the strong asymmetry of the rainfall process should be highly noted when taking measures to defending against geological hazards,such as collapses,landslides and debris flows throughout southwestern China.

  14. Study of anomalous top quark flavor-changing neutral current interactions via the tW channel of single-top-quark production

    International Nuclear Information System (INIS)

    The potential of the LHC for investigation of anomalous top quark interactions with gluon (tug,tcg) through the production of tW channel of single top quarks is studied. In the standard model, the single top quarks in the tW-channel mode are charge symmetric, meaning that σ(pp→t+W-)=σ(pp→t+W+). However, the presence of anomalous flavor-changing neutral current (FCNC) couplings leads to charge asymmetry. In this paper, a method is proposed in which this charge asymmetry may be used to constrain anomalous FCNC couplings. The strength of resulting constraints is estimated for the LHC for the center of mass energies of 7 and 14 TeV.

  16. Fish inner ear otolith size and bilateral asymmetry during development.

    1998-07-01

    Size and bilateral asymmetry (i.e. size difference between the left and the right hand side) of inner ear otoliths of larval mouthbreeding cichlid fish were determined during the ontogenetic development of larvae from hatching to the free swimming stage. Animals of two batches were raised in aquarium hatch baskets. The basket containing one batch was placed directly above aeration equipment, resulting in random water circulation within the basket, which constantly shifted the specimens around ('shifted' specimens). The second batch of animals was raised in parallel without shifting. Due to the weight of the yolk-sacs, these animals lay on their sides until the yolk-sacs were resorbed ('stationary' specimens). The groups of larvae did not differ from one another in respect of individual general development, nor in otolith size. Contrasting results were obtained regarding bilateral otolith asymmetry: In both shifted and stationary animals, asymmetry of utricular and saccular otoliths (lapilli and sagittae, respectively) ranged at comparatively low values throughout development. However, by comparison with shifted individuals, lapillar asymmetry of stationary animals showed a highly significant increase during early development when larvae were forced to lay on their sides due to their prominent yolk-sacs. In later developmental stages, when they began to swim freely, a dramatic decrease in lapillar asymmetry was apparent. These findings indicate that development of lapillar asymmetry depends on the direction of the acting gravity vector relative to the positioning of the larvae, suggesting that the size (or mass) of a given otolith is regulated via a feedback mechanism.

  17. Lepton asymmetry from mixing and oscillations

    Kartavtsev, Alexander; Vogel, Hendrik

    2016-01-01

    We show how the two physically-distinct sources of CP-asymmetry relevant to scenarios of leptogenesis: (i) resonant mixing and (ii) oscillations between different flavours can be unambiguously identified within the Kadanoff-Baym formalism. These contributions are isolated by analyzing the spectral structure of the non-equilibrium propagators without relying on the definition of particle number densities. The mixing source is associated with the usual mass shells, whereas the oscillation source is identified with a third intermediate shell. In addition, we identify terms lying on the oscillation shell that can be interpreted as the destructive interference between mixing and oscillation. We confirm that identical shell structure is obtained in both the Heisenberg- and interaction-picture realizations of the Kadanoff-Baym formalism. In so doing, we illustrate the self-consistency and complementarity of these two approaches. The interaction-picture approach in particular has the advantage that it may be used to ...

  18. Peculiar seasonal effects in the neutrino day-night asymmetry

    Kharlanov, Oleg G

    2015-01-01

    We analyze peculiar effects in the day-night asymmetry of solar neutrinos taking place due to their continuous observation during the night and/or the year. Namely, we show that the day-night effect contains both a trivial, cumulative contribution from the whole observation term and a number of localized terms originating from around the midnights (during the nights) and the two solstices (during the year). We estimate the latter contributions using asymptotical methods and discuss the prospects of their isolation, i.e., magnification, by contraction of the neutrino observation term to small neighborhoods of the localization points. In order to complement our asymptotical predictions derived analytically, we also perform a full numerical analysis of a temporally-weighted observation of the day-night effect, including the energy spectrum of the day-night asymmetry and an estimation of the recoil energy distributions for the elastic-scattering detection channel. According to both analytical and numerical result...

    International Nuclear Information System (INIS)

    The Jefferson Lab Experiment E05-102 'Measurement of Ax' and Az' asymmetries in the quasi-elastic 3He(e,e'd) reaction' was performed in Hall A in 2009. The main physics motivation of the experiment was to investigate the effects of small components of the 3He ground-state wave-function by a simultaneous measurement of double-polarization asymmetries in quasi-elastic kinematics for three exclusive channels, (e,e'd), (e,e'p), and (e,e'n), at almost identical momentum transfers, as well as for (e,e'). This experiment will help map the spin structure of the 3He nucleus onto the picture of the ''free'' polarized neutron. As such, it is of great relevance to the polarized-neutron programs at Jefferson Lab and beyond.

    Asymmetry in gymnastics underpins successful performance and may also have implications as an injury mechanism; therefore, understanding of this concept could be useful for coaches and clinicians. The aim of this study was to examine kinematic and external kinetic asymmetry of the arm segments during the contact phase of a fundamental skill, the forward handspring on floor. Using a repeated single subject design six female National elite gymnasts (age: 19 ± 1.5 years, mass: 58.64 ± 3.72 kg, height: 1.62 ± 0.41 m), each performed 15 forward handsprings, synchronised 3D kinematic and kinetic data were collected. Asymmetry between the lead and non-lead side arms was quantified during each trial. Significant kinetic asymmetry was observed for all gymnasts (p asymmetry being related to the lead leg. All gymnasts displayed kinetic asymmetry for ground reaction force. Kinematic asymmetry was present for more gymnasts at the shoulder than the distal joints. These findings provide useful information for coaching gymnastics skills, which may subjectively appear to be symmetrical. The observed asymmetry has both performance and injury implications.

    While the cosmic baryon asymmetry has been measured at high accuracy to be 6.1*10^-10, a corresponding lepton asymmetry could be as large as 10^-2 if it hides in the neutrino sector. It has been known for some time that a large asymmetry can be generated from a small initial asymmetry given the existence of a sterile neutrino with a mass less than the mass of the active neutrino. While the magnitude of the final lepton asymmetry is deterministic, its sign has been conjectured to be chaotic in nature. This has been proven in the single momentum approximation, also known as the quantum rate equations, but has up to now not been established using the full momentum dependent quantum kinetic equations. Here we investigate this problem by solving the quantum kinetic equations for a system of 1 active and 1 sterile neutrino on an adaptive grid. We show that by increasing the resolution oscillations in the lepton asymmetry are eliminated and that the sign of the lepton asymmetry is in fact deterministic. This paper a...

This has been proven in the single momentum approximation, also known as the quantum rate equations, but has up to now not been established using the full momentum dependent quantum kinetic equations. Here we investigate this problem by solving the quantum kinetic equations for a system of 1 active and 1 sterile neutrino on an adaptive grid. We show that by increasing the resolution, oscillations in the lepton asymmetry can be eliminated so the sign of the final lepton asymmetry is in fact deterministic. This paper also serves as a launch paper for the adaptive solver LASAGNA which is available at http://users-phys.au.dk/steen

  6. The role of asymmetry in formation of the superfluid state in electron–hole systems

    International Nuclear Information System (INIS)

    We consider a system of two coaxial nanotubes separated by a dielectric with the spatially separated electrons and holes confined on each nanotube. The pairing conditions in such systems are studied in the weak coupling limit. It is found that the electron–hole asymmetry caused by electron and hole mass difference and the difference in the radii of the nanotubes can adversely affect the pairing in the system. It is also found that under certain conditions these two asymmetries can effectively compensate each other, therefore significantly increasing the range of the system's parameters for which the superfluid state can exist. - Highlights: • Two coaxial nanotubes with spatially separated carriers are considered. • Mass and geometry asymmetry can adversely affect the pairing and superfluidity. • These two asymmetries can effectively compensate each other to support superfluidity

    The distribution of the azimuthal angle for the charged hadrons has been studied in the hadronic centre-of-mass system for neutral current deep inelastic positron-proton scattering with the ZEUS detector at HERA. Measurements of the dependence of the moments of this distribution on the transverse momenta of the charged hadrons are presented. Asymmetries that can be unambiguously attributed to perturbative QCD processes have been observed for the first time.

  9. Optimal Collusion under Cost Asymmetry

    2005-01-01

    Cost asymmetry is generally thought to hinder collusion because a more efficient firm has both more to gain from a deviation and less to fear from retaliation than less efficient firms. Our paper reexamines this conventional wisdom and characterizes optimal collusion without any prior restriction on the class of strategies. We first stress that firms can credibly agree on retaliation schemes that maximally punish even the most efficient firm. This implies that whenever collusion is sustainabl...

    Capsaicin is the most abundant pungent molecule present in red peppers and it is widely used for food flavoring, in pepper spray in self-defense devices and more recently in ointments for the relief of neuropathic pain. Capsaicin is a selective agonist of transient receptor potential channel, vanilloid subfamily member 1. A selective and sensitive quantitative method for the determination of capsaicin by LC-ESI/MS/MS was developed. The method consisted of a protein precipitation extraction followed by analysis using liquid chromatography electrospray quadrupole ion trap mass spectrometry. The chromatographic separation was achieved using a 100 x 2 mm C(18) Waters Symmetry column combined with a gradient mobile phase composed of acetonitrile and 0.1% formic acid aqueous solution at a flow rate of 220 microL/min. The mass spectrometer was operating in full-scan MS/MS mode using two-segment analysis. An analytical range of 10-5000 ng/mL was used in the calibration curve constructed in rat plasma. The interbatch precision and accuracy observed were 6.5, 6.7, 5.3 and 101.2, 102.7, 103.5% at 50, 500 and 5000 ng/mL, respectively. An in vitro metabolic stability study was performed in rat, dog and mouse liver microsomes and the novel analytical method was adapted and used to determine intrinsic clearance of capsaicin. Results suggest very rapid degradation with T(1/2) ranging from 2.3 to 4.1 min and high clearance values suggesting that drug bioavailability will be considerably reduced, consequently affecting drug response and efficacy.

    Study design Are there neuro-anatomical abnormalities associated with idiopathic scoliosis (IS)? Posterior Basicranium (PBA) reflects cerebellum growth and contains vestibular organs, two structures suspected to be involved in scoliosis. Objective The aim of this study was to compare posterior basicranium asymmetry (PBA) in Idiopathic scoliosis (IS) and normal subjects. Method: To measure the shape of PBA in 3D, we defined an intra-cranial frame of reference based on CNS and guided by embryology of the neural tube. Measurements concerned three directions of space referred to a specific intra cranial referential. Data acquisition was performed with T2 MRI (G.E. Excite 1.5T, mode Fiesta). We explored a scoliosis group of 76 women and 20 men with a mean age of 17, 2 and a control group of 26 women and 16 men, with a mean age of 27, 7. Results: IS revealed a significant asymmetry of PBA (Pr>|t|<.0001) in 3 directions of space compared to the control group. This asymmetry was more pronounced in antero-posterior...

    Full Text Available The purpose of this study is to investigate the impact of some corporate governance mechanisms on information asymmetry. From among different mechanisms of corporate governance, the number of board members who were not responsible, ownership concentration and the percentage of institutional ownership are considered. Time scale of the study includes the years from 2005 to 2011. Sampling was performed among all the companies accepted in Tehran Stock Exchange using systematic removal method. This sample includes 504 companies-years. This is a post-event study. Experimentally, this study lies in accounting proving research areas and it is based on financial statements of the firms, and regarding purpose is application. Descriptive method has been used in this study. The findings show that there was a positive and significant relationship between the number of board members who are not responsible and the percentage of institutional ownership from the one side, and information asymmetry from the other. In addition, the findings show a negative significant relationship between ownership concentration and information asymmetry.

  15. Measurement of differential tt cross sections in the dilepton decay channels with the CMS detector at 7 TeV centre-of-mass energy

    International Nuclear Information System (INIS)

    After commissioning of the Large Hadron Collider at the European nuclear research centre CERN, the CMS detector had recorded data with an integrated luminosity of 1.1 fb-1 at a centre-of-mass energy of 7 TeV already in Summer 2011. With this, it was possible for the first time to accurately measure properties of the top quark with high statistics. The work presented here focuses on the measurement of normalised differential top quark pair production cross sections in the decay channel into final states with two oppositely charged leptons. The measurement is presented in dependence of kinematic properties of the top quarks, the top quark pair, the leptons, and the lepton pair. The distributions allow for detailed testing of perturbative quantum chromodynamics and thus the Standard Model of particle physics. Many of the distributions are also sensitive to processes beyond the Standard Model. In this work, comparisons of the measured cross sections with three different predictions are shown. The result is that the predictions are in accordance with the measurement, only a slight deviation of the prediction from the measurement is visible in few distributions. In the outlook it is shown that a fourth, more accurately calculated prediction for the measurement of the top quark transverse momentum normalised differential cross section is in even better agreement with the data. Thus it can be concluded that the Standard Model was tested successfully and that no hints for new physics are found.

Here, we report the mass spectrometric analysis of free thiols in RyR1 using the lipophilic, thiol-specific probe monobromobimane (MBB. In the presence of reduced glutathione, MBB labeled 14 cysteines per RyR1 subunit in tryptic peptides in five of five experiments. Forty-six additional MBB-labeled cysteines per RyR1 subunit were detected with lower frequency in tryptic peptides, bringing the total number of MBB-labeled cysteines to 60 per RyR1 subunit. A combination of fluorescence detection and mass spectrometry of RyR1, labeled in the presence of reduced and oxidized glutathione, identified two redox-sensitive cysteines (C1040 and C1303. Regulation of RyR activity by reduced and oxidized glutathione was investigated in skeletal muscle mutant RyR1s in which 18 cysteines were substituted with serine or alanine, using a [3H]ryanodine ligand binding assay. Three single-site RyR1 mutants (C1781S, C2436S, and C2606S and two multisite mutants with five and seven substituted cysteines exhibited a reduced redox response compared with wild-type RyR1. The results suggest that multiple cysteines determine the redox state and activity of RyR1.Keywords: mass spectrometry, mutagenesis, ryanodine receptor, redox modification of cysteines

  18. Models of neutrino masses and baryogenesis

    Indian Academy of Sciences (India)

    Utpal Sarkar

    2000-01-01

    Majorana masses of the neutrino implies lepton number violation and is intimately related to the lepton asymmetry of the universe, which gets related to the baryon asymmetry of the universe in the presence of the sphalerons during the electroweak phase transition. Assuming that the baryon asymmetry of the universe is generated before the electroweak phase transition, it is possible to discriminate different classes of models of neutrino masses. While see-saw mechanism and the triplet Higgs mechanism are preferred, the Zee-type radiative models and theR-parity breaking models requires additional inputs to generate baryon asymmetry of the universe during the electroweak phase transition.

    Dentofacial asymmetry is quite common and when sufficiently severe can require surgical orthodontic intervention. Asymmetries can be classified according to the structures involved into skeletal, dental and functional. In diagnosing asymmetries, a thorough clinical examination and radiographic survey are essential to determine the extent of soft tissue, skeletal, dental and functional involvement. Dental asymmetries, as well as a variety of functional deviations, can be managed orthodontically, whereas significant structural facial asymmetries require a comprehensive orthodontic and orthognathic management. With less severe dental, skeletal and soft tissue deviations the advisability of treatment should be carefully considered. The following article also contains a case report highlighting the importance of proper diagnosis in treatment plan for management of dentofacial asymmetry. PMID:26229387

We derive, in particular, the constraints on the mass splitting of a pair of singlet fermions, and on the strength of their coupling...

  1. Lepton asymmetry from mixing and oscillations

    Science.gov (United States)

    Kartavtsev, A.; Millington, P.; Vogel, H.

    2016-06-01

    We show how the two physically-distinct sources of CP -asymmetry relevant to scenarios of leptogenesis: (i) resonant mixing and (ii) oscillations between different flavours can be unambiguously identified within the Kadanoff-Baym formalism. These contributions are isolated by analyzing the spectral structure of the non-equilibrium propagators without relying on the definition of particle number densities. The mixing source is associated with the usual mass shells, whereas the oscillation source is identified with a third intermediate shell. In addition, we identify terms lying on the oscillation shell that can be interpreted as the destructive interference between mixing and oscillation. We confirm that identical shell structure is obtained in both the Heisenberg- and interaction-picture realizations of the Kadanoff-Baym formalism. In so doing, we illustrate the self-consistency and complementarity of these two approaches. The interaction-picture approach in particular has the advantage that it may be used to analyze all forms of mass spectra from quasi-degenerate through to hierarchical.

    The relationship between aggression and brain asymmetries has not been studied enough. The association between both concepts can be approached from two different perspectives. One perspective points to brain asymmetries underlying the emotion of anger and consequently aggression in normal people. Another one is concerned with the existence of brain asymmetries in aggressive people (e.g., in the case of suicides or psychopathies). Research on emotional processing points out the confusion betw...

    Previously, we explored the functionality of a tri-leaflet anal valve of a dragonfly larva. We saw that the dragonfly larva is capable of controlling the three leaflets independently to asymmetrically open the nozzle. Such control resulted in vectoring of the jet in various directions. To further understand the effect of asymmetric nozzle orifice, we tested jet flow through circular asymmetric nozzles. We report the relationship between nozzle asymmetry and redirecting of the jet at various Reynolds numbers. This material is based upon work supported by the National Science Foundation under Grant No. CBET-1511414; additional support by the National Science Foundation Graduate Research Fellowship under Grant No. DGE-1144469.

  9. Quantum speed limits, coherence, and asymmetry

    2016-05-01

    The resource theory of asymmetry is a framework for classifying and quantifying the symmetry-breaking properties of both states and operations relative to a given symmetry. In the special case where the symmetry is the set of translations generated by a fixed observable, asymmetry can be interpreted as coherence relative to the observable eigenbasis, and the resource theory of asymmetry provides a framework to study this notion of coherence. We here show that this notion of coherence naturally arises in the context of quantum speed limits. Indeed, the very concept of speed of evolution, i.e., the inverse of the minimum time it takes the system to evolve to another (partially) distinguishable state, is a measure of asymmetry relative to the time translations generated by the system Hamiltonian. Furthermore, the celebrated Mandelstam-Tamm and Margolus-Levitin speed limits can be interpreted as upper bounds on this measure of asymmetry by functions which are themselves measures of asymmetry in the special case of pure states. Using measures of asymmetry that are not restricted to pure states, such as the Wigner-Yanase skew information, we obtain extensions of the Mandelstam-Tamm bound which are significantly tighter in the case of mixed states. We also clarify some confusions in the literature about coherence and asymmetry, and show that measures of coherence are a proper subset of measures of asymmetry.

    1986-03-01

    Inuit (Eskimos) from the Foxe Basin region of the Northwest Territories, Canada, were studied to ascertain the amount of dimensional and morphological asymmetry in their dentitions. The results indicate that dimensional asymmetry does not appear to be greater on either the maxillary or mandibular teeth. Both types of asymmetry show partial conformity to the model of tooth fields with an increasing amount of asymmetry as one goes distally in each tooth group. The morphological asymmetry exception, the mandibular incisors, follows Dahlberg's "Field Concept." Rank-order correlations between the amount of dimensional asymmetry and morphological asymmetry reveal no detectable patterns. There appear to be no associations between the presence or absence of morphological asymmetry and the size of the tooth. This lack of association might be explained by differences in developmental timing of tooth dimensions and morphological traits; however, such a hypothesis requires experimental testing. In this population and those for which published results are available, it is practically impossible to overcome the "noise" level and test recent hypotheses regarding random dental asymmetry.

    We study single spin asymmetries of D{sup 0} and D{sup -} mesons in polarized proton-proton collisions. A two component model is used to describe charm meson production. The production of D mesons occurs by recombination of the constituents present in the initial state as well as by fragmentation of quarks in the final state. This model has proved to describe the production of charm. The recombination component involves a mechanism of spin alignment that ends up in a single spin asymmetry. Experimental measurements of single spin asymmetry for pions at RHIC are compared with the model. Predictions for the asymmetry in D mesons are presented. (orig.)

  13. Asymmetries and Anomalous Phenomena in Ionic Transport Through Nonchalance's

    International Nuclear Information System (INIS)

    Biological and synthetic nanochannels exhibit two essential biophysical properties: selective ion conduction and the ability to gate open in response to appropriate stimulus. Both these properties are related to several untypical modes of behaviour of the diffusional and conduction currents, absent in the normal (electro-)diffusion. We present our recent results concerning some of such anomalous phenomena. Selectivity is related to the fact that electrical and diffusive currents exhibit several asymmetries - the asymmetric channels rectify the electric currents: the relation I versus U is asymmetric (this is related to the pumping effect observed in synthetic nanochannels), moreover, for U = 0 the magnitude of purely diffusional currents depends on the direction of the concentration gradient. These phenomena can be described by a model based on the continuous description starting from the Smoluchowski equation. The flicker noise in the power spectra of ionic currents is known to be present both in very narrow biological and (some) synthetic channels. We simulated the motion of K+ ions of the single-file type through a model channel with the gate which opens and closes under influence of both random noise, and interactions with ions present inside the channel. We found that there is a range of the varied parameters, in which the power spectrum has the characteristics of the flicker noise. Critical for the appearance of the flicker noise are the condition of single-file motion of ions through the channel and the opening/closing of the gate. (author)

  14. Background check for anomalous like-sign dimuon charge asymmetry

    International Nuclear Information System (INIS)

    The D0 Collaboration has reported an excess of roughly 1% of μ-μ- pairs over μ+μ+ pairs in pp collisions at a center-of-mass energy √(s)=1.96 GeV at the Fermilab Tevatron, when known backgrounds are subtracted. This excess, if ascribed to CP violation in meson-antimeson mixing of nonstrange or strange neutral B mesons, is about 40 times that expected in the standard model. We propose a null test, based on a tight restriction on the muon impact parameter b, to confirm that this excess is indeed due to B mesons. If the asymmetry is due to anomalous CP violation in Bs-Bs mixing, then a tight restriction on b would increase by a factor 2 the net asymmetry from neutral B mixing, while the sample of dimuons from neutral B decays will be reduced significantly relative to background events.

  15. Can the Baryon Asymmetry Arise From Initial Conditions?

    In this letter, we quantify the challenge of explaining the baryon asymmetry using initial conditions in a universe that undergoes inflation. Contrary to lore, we find that such an explanation is possible if net $B-L$ number is stored in a light bosonic field with hyper-Planckian initial displacement and a delicately chosen field velocity prior to inflation. However, such a construction may require extremely tuned coupling constants to ensure that this asymmetry is viably communicated to the Standard Model after reheating; the large field displacement required to overcome inflationary dilution must not induce masses for Standard Model particles or generate dangerous washout processes. While these features are inelegant, this counterexample nonetheless shows that there is no theorem against such an explanation. We also comment on potential observables in the double $\\beta$-decay spectrum and on model variations that may allow for more natural realizations.

    The exclusive channel polarized proton(polarized e,e prime p)pi0 was studied in the first and second nucleon resonance regions in the Q2 range from 0.187 to 0.770 GeV2 at Jefferson Lab using the CEBAF Large Acceptance Spectrometer (CLAS). Longitudinal target and beam-target asymmetries were extracted over a large range of center-of-mass angles of the pi0 and compared to the unitary isobar model MAID, the dynamic model by Sato and Lee, and the dynamic model DMT. A strong sensitivity to individual models was observed, in particular for the target asymmetry and in the higher invariant mass region. This data set, once included in the global fits of the above models, is expected to place strong constraints on the electrocoupling amplitudes A_{1/2} and S_{1/2} for the Roper resonance N(1400)P11, and the N(1535)S11 and N(1520)D13 states.

    Measurements of the top--antitop quark pair production charge asymmetry in the dilepton channel are presented using data corresponding to an integrated luminosity of $20.3$ fb$^{-1}$ from $pp$ collisions at a center-of-mass energy of $\\sqrt{s} = 8$ TeV collected with the ATLAS detector at the Large Hadron Collider at CERN. Inclusive and differential measurements as a function of the invariant mass, transverse momentum, and longitudinal boost of the $t\\bar{t}$ system are performed both in the full phase space and in a fiducial phase space closely matching the detector acceptance. Two observables are studied: $A^{\\ell\\ell}_{\\textrm{C}}$ based on the selected leptons and $A^{t\\bar{t}}_{\\textrm{C}}$ based on the reconstructed $t\\bar{t}$ final state. The inclusive asymmetries are measured in the full phase space to be $A^{\\ell\\ell}_{\\textrm{C}} = 0.008 \\pm 0.006$ and $A^{t\\bar{t}}_{\\textrm{C}} = 0.021 \\pm 0.016$, which are in agreement with the Standard Model predictions of $A^{\\ell\\ell}_{\\textrm{C}} = 0.006...

    The exclusive channel polarized proton(polarized e,e prime p)pi0 was studied in the first and second nucleon resonance regions in the Q2 range from 0.187 to 0.770 GeV2 at Jefferson Lab using the CEBAF Large Acceptance Spectrometer (CLAS). Longitudinal target and beam-target asymmetries were extracted over a large range of center-of-mass angles of the pi0 and compared to the unitary isobar model MAID, the dynamic model by Sato and Lee, and the dynamic model DMT. A strong sensitivity to individual models was observed, in particular for the target asymmetry and in the higher invariant mass region. This data set, once included in the global fits of the above models, is expected to place strong constraints on the electrocoupling amplitudes A_{1/2} and S_{1/2} for the Roper resonance N(1400)P11, and the N(1535)S11 and N(1520)D13 states.

  20. Whistled Turkish alters language asymmetries.

    Whistled languages represent an experiment of nature to test the widely accepted view that language comprehension is to some extent governed by the left hemisphere in a rather input-invariant manner. Indeed, left-hemisphere superiority has been reported for atonal and tonal languages, click consonants, writing and sign languages. The right hemisphere is specialized to encode acoustic properties like spectral cues, pitch, and melodic lines and plays a role for prosodic communicative cues. Would left hemisphere language superiority change when subjects had to encode a language that is constituted by acoustic properties for which the right hemisphere is specialized? Whistled Turkish uses the full lexical and syntactic information of vocal Turkish, and transforms this into whistles to transport complex conversations with constrained whistled articulations over long distances. We tested the comprehension of vocally vs. whistled identical lexical information in native whistle-speaking people of mountainous Northeast Turkey. We discovered that whistled language comprehension relies on symmetric hemispheric contributions, associated with a decrease of left and a relative increase of right hemispheric encoding mechanisms. Our results demonstrate that a language that places high demands on right-hemisphere typical acoustical encoding creates a radical change in language asymmetries. Thus, language asymmetry patterns are in an important way shaped by the physical properties of the lexical input. PMID:26294179

  1. Breaking symmetry: the marine environment, prey size, and the evolution of asymmetry in cetacean skulls.

    Skulls of odontocetes (toothed whales, including dolphins and porpoises) are typified by directional asymmetry, particularly in elements associated with the airway. Generally, it is assumed this asymmetry is related to biosonar production. However, skull asymmetry may actually be a by-product of selection pressure for an asymmetrically positioned larynx. The odontocete larynx traverses the pharynx and is held permanently in place by a ring of muscle. This allows prey swallowing while remaining underwater without risking water entering the lungs and causing injury or death. However, protrusion of the larynx through the pharynx causes a restriction around which prey must pass to reach the stomach. The larynx and associated hyoid apparatus has, therefore, been shifted to the left to provide a larger right piriform sinus (lateral pharyngeal food channel) for swallowing larger prey items. This asymmetry is reflected in the skull, particularly the dorsal openings of the nares. It is hypothesized that there is a relationship between prey size and skull asymmetry. This relationship was examined in 13 species of odontocete cetaceans from the northeast Atlantic, including four narrow-gaped genera (Mesoplodon, Ziphius, Hyperoodon, and Kogia) and eight wide-gaped genera (Phocoena, Delphinus, Stenella, Lagenorhynchus, Tursiops, Grampus, Globicephala, and Orcinus). Skulls were examined from 183 specimens to assess asymmetry of the anterior choanae. Stomach contents were examined from 294 specimens to assess prey size. Results show there is a significant positive relationship between maximum relative prey size consumed and average asymmetry relative to skull size in odontocete species (wide-gape species: R2 = 0.642, P = 0.006; narrow-gape species: R2 = 0.909, P = 0.031). This finding provides support for the hypothesis that the directional asymmetry found in odontocete skulls is related to an aquatic adaptation enabling swallowing large, whole prey while maintaining respiratory

    We investigate the forward-backward asymmetries in the pair production of fourth family fermions through the new Z' interactions in the e+e- collisions. The Z' boson having family universal couplings can contribute to the pair production of fourth family fermions via the s-channel exchange. The linear colliders will provide a clean environment for the physics of Z' boson to measure its couplings precisely. The effects of the Z' boson to the asymmetries are shown to be important in some parame...

    We investigate the forward-backward asymmetries in the pair production of fourth family fermions through the new Z' interactions in the e^{+}e^{-} collisions. The Z' boson having family universal couplings can contribute to the pair production of fourth family fermions via the s-channel exchange. The linear colliders provide a clean environment for the physics of Z' boson to measure its couplings precisely. The effects of the Z' boson to the asymmetries are shown to be important in some parameter regions for different Z' models. The sensitivities to the family universal couplings has been estimated for different collider energies and projected luminosities.

  4. Entrance channel dependence of fission fragment anisotropies - a direct experimental signature of fission before equilibration

    International Nuclear Information System (INIS)

    In several cases of heavy ion induced fusion-fission reactions, the fission fragment angular distributions exhibit much larger anisotropies than predicted by the standard Halpern-Strutinsky theory. Several explanations have been put forward to interpret these anomalous angular distributions. One of them is that a characteristic signature of fission before full K-equilibration will be an entrance channel dependence of the fragment anisotropies for target-projectile combinations across the Businaro-Gallone ridge in the mass/charge asymmetry degree of freedom. To look for any such entrance channel dependence of fragment anisotropies, we have carried out measurements of fragment angular distributions in fission induced by boron, carbon, oxygen ions on thorium and neptunium targets and by fluorine ions on neptunium target at above barrier energies.

    2013-01-01

    We show that a simple macroeconomic model with collateral constraints displays strong asymmetric responses to boom and bust periods. In a boom triggered by a rise in asset values, constraints become more and more relaxed, the collateral channel is weaker, and the response of aggregate consumption (and output) to a wealth shock is positive but small. In a recession, collateral constraints get tighter and tighter, the collateral channel gets stronger, and the response in consumption from a give...

    show that the FDA exhibits a predominant tendency of shorter duration of low water slack, favoring the landward transport of fine sediment. The FVA demonstrates prevailing ebb dominance in the study period, favoring the seaward transport of coarse sediment. This ebb dominance is primarily induced by the interaction among the residual flow and the tidal constituents. The external TDA in the ocean experiences distinct cyclic variations with positive asymmetry when semidiurnal tides dominate and negative asymmetry during the periods when diurnal tides dominate. The funnel shape of the HE is advantageous for the development of positive tidal asymmetry as the semidiurnal tides are more amplified than the diurnal tides. The effect of river flow can enhance the ebb dominance, while the baroclinic effect is more complex. The existence of channel and shoals favors the development of residual pattern with seaward flow (ebb dominance) in the channel and landward flow (flood dominance) at the shoal when the tides are strong (semidiurnal tides dominate) and the residual pattern with landward flow (flood dominance) in the channel and seaward flow (ebb dominance) at the shoal when the baroclinic effect is dominant (diurnal tides dominate).

    An improved measurement of the mass of the Higgs boson is derived from a combined fit to the invariant mass spectra of the decay channels $H\\rightarrow \\gamma\\gamma$ and $H{\\rightarrow\\,}ZZ^{*}{\\rightarrow\\,}4\\ell$. The analysis uses the $pp$ collision data sample recorded by the ATLAS experiment at the CERN Large Hadron Collider at center-of-mass energies of 7 TeV and 8~TeV, corresponding to an integrated luminosity of 25 fb$^{-1}$. The measured value of the Higgs boson mass is $m_{H} = 125.36 \\pm 0.37 \\,\\mathrm{(stat)} \\pm 0.18 \\,\\mathrm{(syst)}$ GeV. This result is based on improved energy-scale calibrations for photons, electrons, and muons as well as other analysis improvements, and supersedes the previous result from ATLAS. Upper limits on the total width of the Higgs boson are derived from fits to the invariant mass spectra of the $H\\rightarrow \\gamma\\gamma$ and $H{\\rightarrow\\,}ZZ^{*}{\\rightarrow\\,}4\\ell$ decay channels.

    The top quark mass was measured in the channels $t\\bar{t} \\to \\mathrm{lepton+jets}$ and $t\\bar{t} \\to \\mathrm{dilepton}$ (lepton=$e, \\mu$) based on ATLAS data recorded in 2011. The data were taken at the LHC with a proton--proton centre-of-mass energy of $\\sqrt{s}=7$ TeV and correspond to an integrated luminosity of 4.6fb$^{-1}$. The $t\\bar{t} \\to \\mathrm{lepton+jets}$ analysis uses a three-dimensional template technique which determines the top quark mass together with a global jet energy scale factor (JSF), and a relative $b$-to-light-jet energy scale factor (bJSF), where the terms $b$-jets and light-jets refer to jets originating from $b$-quarks and $u, d, c, s$-quarks or gluons, respectively. The analysis of the $t\\bar{t} \\to \\mathrm{dilepton}$ channel exploits a one-dimensional template method using the $m_{\\ell b}$ observable, defined as the average invariant mass of the two lepton+$b$-jet pairs in each event. The top quark mass is measured to be $172.33\\pm 0.75(\\rm {stat}) \\pm 1.02(\\rm {syst})$ GeV, an...

    The underlying mechanism of search asymmetry is still unknown. Many computational models postulate top-down selection of target-defining features as a crucial factor. This feature selection account implies, and other theories implicitly assume, that predefined target identity is necessary for search asymmetry. The authors tested the validity of…

    The helicity modification of light polarization which is induced by the gravitational deflection from a classical heavy rotating body, like a star or a planet, is considered. The expression of the helicity asymmetry is derived; this asymmetry signals the gravitationally induced spin transfer from the rotating body to the scattered photons.

    1998-01-01

    A small asymmetry in the flux of neutrinos emitted by a hot newly-born neutron star could explain the observed motions of pulsars. However, even in the presence of parity-violating processes with anisotropic scattering amplitudes, no asymmetry is generated in thermal equilibrium. We explain why this no-go theorem stymies some of the proposed explanations for the pulsar ``kick'' velocities.

  16. East-west asymmetry of Saturn's rings

    International Nuclear Information System (INIS)

    Measurements made in 1974-1975 at the Aarne Karjalainen Observatory do not show any east-west asymmetry of Saturn's rings. Combining the photometric data available for 1913-1975, one finds that the asymmetry varies in an irregular manner without correlating with Saturn's orbital period. (Auth.)

    During ontogeny, the nasal septum exerts a morphogenetic influence on the surrounding facial skeleton. While the influence of the septum is well established in long snouted animal models, its role in human facial growth is less clear. If the septum is a facial growth center in humans, we would predict that deviated septal growth would be associated with facial skeletal asymmetries. Using computed tomographic (CT) scans of n = 55 adult subjects, the purpose of this study was to test whether there is a correlation between septal deviation and facial asymmetries using three-dimensional (3D) geometric morphometric techniques. We calculated deviation as a percentage of septal volume relative to the volume of a modeled non-deviated septum. We then recorded skeletal landmarks representing the nasal, palatal, and lateral facial regions. Landmark data were superimposed using Procrustes analysis. First, we examined the correlation between nasal septal deviation and the overall magnitude of asymmetry. Next, we assessed whether there was a relationship between nasal septal deviation and more localized aspects of asymmetry using multivariate regression analysis. Our results indicate that while there was no correlation between septal deviation and the overall magnitude of asymmetry, septal deviation was associated with asymmetry primarily in the nasal floor and the palatal region. Septal deviation was unassociated with asymmetries in the lateral facial skeleton. Though we did not test the causal relationship between nasal septal deviation and facial asymmetry, our results suggest that the nasal septum may have an influence on patterns of adult facial form.

  19. Asymmetry in body composition in female hockey players.

    2015-08-01

    The aim of the study was to determine if a sport in which one side of the body is dominant, like field hockey, influences regional body composition and bone mineral density (BMD) distribution in particular body segments, and whether the sporting level is a determining factor. Dual energy X-ray absorptiometry (DXA) method (Lunar Prodigy Advance; General Electric, Madison, USA) with the whole body scan was used to measure bone mineral density, fat mass and lean mass in 31 female field hockey players divided according to their sporting level. The morphological asymmetry level was assessed between two body sides and body segments in athletes from the National Team (n=17) and from the Youth Team (n=14) separately and between groups. Bone mineral density in the lower extremity and of the trunk was significantly asymmetric in favor of the left side in the National Team. In the case of the Youth Team, only the trunk BMD indicated clear left-right difference with left side dominance. Both the lean mass and fat mass values were relatively higher on the left side of all body segments and it related to both analyzed groups of athletes. The present study shows that playing field hockey contributes to laterality in body composition and BMD and that the sporting level is a determining factor. In most cases the left side dominated. A greater asymmetry level was observed in more experienced female field hockey players. PMID:26077573

  20. Chargino contributions to the CP asymmetry in B -> Phi K(S) decay

    2003-01-01

    We perform a model independent analysis of the chargino contributions to the CP asymmetry in B -> Phi K(S) process. We use the mass insertion approximation method generalized by including the possibility of a light right-stop. We find that the dominant effect is given by the contributions of the mass insertions deltaU_LL(32) and deltaU_RL(32) to the Wilson coefficient of the chromomagnetic operator. By considering both these contributions simultaneously, the CP asymmetry in B -> Phi K(S) process is significantly reduced and negative values, which are within the 1-sigma experimental range and satisfy the b -> s gamma constraints, can be obtained.

    In a sample of 471 million BB events collected with the BABAR detector at the PEP-II e+e- collider we study the rare decays B -> K(*) l+ l-, where l+ l- is either e+e- or mu+mu-. We report results on partial branching fractions and isospin asymmetries in seven bins of di-lepton mass-squared. We further present CP and lepton-flavor asymmetries for di-lepton masses below and above the J/psi resonance. We find no evidence for CP or lepton-flavor violation.

    The conventional seesaw-leptogenesis can simultaneously explain the suppression of neutrino masses and the generation of cosmic baryon asymmetry, but usually cannot predict an unambiguous relation between these two sectors. In this work we shall demonstrate a novel left-right symmetric scenario, motivated to solve the strong CP problem by parity symmetry, where the present baryon asymmetry is determined by three charged lepton masses and a seesaw-suppressed hermitian Dirac neutrino mass matri...

  3. Bs semileptonic asymmetry at LHCb

    2016-01-01

    When neutral $B^{0}_{s,d}$ mesons evolve in time they can change into their own antiparticles. In this mixing process CP symmetry is not necessarily conserved, as the probability for a $B^{0}$ meson to change into a $\\bar{B}^{0}$ meson can be different from the probability for the reverse process. The CP violation in the $B^{0}_{s}$ system as measured using semileptonic decays, defined as $a^{s}_{sl}$, is very small according to the Standard Model. However, earlier measurements of the semileptonic mixing asymmetry in both the $B_s^{0}$ and $B_d^{0}$ systems have shown a $3 \\sigma$ deviation with respect to the Standard Model value. A measurement of $a^{s}_{sl}$ performed using $1 \\text{fb}^{-1}$ of data collected at the LHCb detector is presented, together with an outlook to the updated $3 \\text{fb}^{-1}$ result.

    We require that the primordial baryon asymmetry is not washed out in the seesaw model compatible with the recent results of WMAP and the neutrino oscillation experiments including the first results of KamLAND. We find that only the case of the normal neutrino mass hierarchy with an approximate $L_{e}$-symmetry satisfies the requirement. We further derive, depending on the signs of neutrino mass eigenvalues, three types of neutrino mass matrixes, where the values of each element are rather pre...

  6. THE UNIFICATION OF ASYMMETRY SIGNATURES OF TYPE Ia SUPERNOVAE

    International Nuclear Information System (INIS)

    We present a compilation of the geometry measures acquired using optical and IR spectroscopy and optical spectropolarimetry to probe the explosion geometry of Type Ia supernovae (SNe Ia). Polarization measurements are sensitive to asymmetries in the plane of the sky, whereas line profiles in nebular phase spectra are expected to trace asymmetries perpendicular to the plane of the sky. The combination of these two measures can overcome their respective projection effects, completely probing the structures of these events. For nine normal SNe Ia, we find that the polarization of Si II λ6355 at 5 days before maximum (pSiII) is well correlated with its velocity evolution (v-dotSiii), implying that v-dotSiii is predominantly due to the asymmetry of the SNe. We find only a weak correlation between the polarization of Si II and the reported velocities (vneb) for peak emission of optical Fe II and Ni II lines in nebular spectra. Our sample is biased, with polarization measurements being only available for normal SNe that subsequently exhibited positive (i.e., redshifted) vneb. In unison these indicators are consistent with an explosion in which the outer layers are dominated by a spherical oxygen layer, mixed with an asymmetric distribution of intermediate-mass elements. The combination of spectroscopic and spectropolarimetric indicators suggests a single geometric configuration for normal SNe Ia, with some of the diversity of observed properties arising from orientation effects.

  7. Entropy, baryon asymmetry and dark matter from heavy neutrino decays

    Energy Technology Data Exchange (ETDEWEB)

    Buchmueller, W.; Schmitz, K.; Vertongen, G.

    2011-04-15

    The origin of the hot phase of the early universe remains so far an unsolved puzzle. A viable option is entropy production through the decays of heavy Majorana neutrinos whose lifetimes determine the initial temperature. We show that baryogenesis and the production of dark matter are natural by-products of this mechanism. As is well known, the cosmological baryon asymmetry can be accounted for by lepto- genesis for characteristic neutrino mass parameters. We nd that thermal gravitino production then automatically yields the observed amount of dark matter, for the gravitino as the lightest superparticle and typical gluino masses. As an example, we consider the production of heavy Majorana neutrinos in the course of tachyonic preheating associated with spontaneous B-L breaking. A quantitative analysis leads to contraints on the superparticle masses in terms of neutrino masses: For a light neutrino mass of 10{sup -5} eV the gravitino mass can be as small as 200 MeV, whereas a lower neutrino mass bound of 0.01 eV implies a lower bound of 9 GeV on the gravitino mass. The measurement of a light neutrino mass of 0.1 eV would rule out heavy neutrino decays as the origin of entropy, visible and dark matter. (orig.)

    This paper reports inclusive and differential measurements of the $t\\bar{t}$ charge asymmetry $A_{\\text{C}}$ in 20.3 fb$^{-1}$ of $\\sqrt{s} = 8$ TeV $pp$ collisions recorded by the ATLAS experiment at the Large Hadron Collider at CERN. Three differential measurements are performed as a function of the invariant mass, transverse momentum and longitudinal boost of the $t\\bar{t}$ system. The $t\\bar{t}$ pairs are selected in the single-lepton channels ($e$ or $\\mu$) with at least four jets, and a likelihood fit is used to reconstruct the $t\\bar{t}$ event kinematics. A Bayesian unfolding procedure is performed to infer the asymmetry at parton level from the observed data distribution. The inclusive $t\\bar{t}$ charge asymmetry is measured to be $A_{\\text{C}} = 0.009 \\pm 0.005$ (stat.$+$syst.). The inclusive and differential measurements are compatible with the values predicted by the Standard Model.

    In orthodontic diagnosis, facial symmetry is important. The aim of the present study was to analyse the perception of various degrees of facial asymmetry exhibited by carefully designed virtual three-dimensional (3D) material. Three groups of raters (30 orthodontists, 30 maxillofacial surgeons, and 30 laymen) rated, using a six-point scale, the degree of asymmetry of eight randomly presented 3D faces exhibiting incremental soft tissue alterations. The faces were created by gradually transforming the nose or chin in increments of 2 mm away from the computed symmetry plane. Differences between the groups in analysis of facial asymmetry, the rating of facial stimulus, and right and left facial asymmetry were determined using a t-test. The results demonstrated that raters' profession did not influence the point at which they identified asymmetry. Even laymen were able to detect asymmetries when located near the midline of 3D faces. All raters identified asymmetries of the nose as more negative than those of the same degree of the chin. A left-sided deviation of the nose along the facial symmetry plane lead to a more negative rating of facial appearance, whereas a right-sided deviation of the chin was rated as less attractive. Nasal architecture plays a crucial role in the perception of symmetry. These findings provide clinicians with a greater understanding of how faces are perceived, a process which is of particular interest in treating orthognathic patients, and those with congenital anomalies.

  10. LHCb; Measurement of the forward-central $b \\bar{b}$ production asymmetry

    CDF and D0 collaborations results suggests that the top-quark forward-backward production asymmetry is much larger than the Standard Model (SM) predictions. Measuring the $b \\bar{b}$ asymmetry production would provide constraint on the flavor structure of any model that attempts to explain the CDF and D0 results. A measurement of the forward-central (FC) $b\\bar{b}$ production asymmetry is presented based on the LHCb data collected in 2011 at $\\sqrt{s}$ = 7 TeV corresponding to an integrated luminosity of 1.0 fb$^{-1}$ using selected events that have two identified $b$ jets, one of which is flavor tagged by one muon with high momentum. The FC asymmetry is defined as \\begin{align} A^{b \\bar{b}}_{FC}=\\frac{N(\\Delta y > 0)-N(\\Delta y 0)+N(\\Delta y 100$ GeV the expected asymmetry is about $\\cal{O}$(0.1 %) where gluon fusion which has no asymmetry is less dominant at high mass.

  11. Measurement of Branching Fractions and Rate Asymmetries in the Rare Decays B -> K(*) l+ l-

    In a sample of 471 million BB events collected with the BABAR detector at the PEP-II e+e- collider we study the rare decays B -> K(*) l+ l-, where l+ l- is either e+e- or mu+mu-. We report results on partial branching fractions and isospin asymmetries in seven bins of di-lepton mass-squared. We further present CP and lepton-flavor asymmetries for di-lepton masses below and above the J/psi resonance. We find no evidence for CP or lepton-flavor violation. The partial branching fractions and isospin asymmetries are consistent with the Standard Model predictions and with results from other experiments.

  12. A Survey of Beam Asymmetries in Semi-exclusive Electron Scattering on {sup 4}He and {sup 12}C

    A study of the polarized electron beam asymmetry in semi-exclusive (e,e{prime}p) reactions on {sup 4}He and {sup 12}C over a large kinematic range has been performed. The beam asymmetry A{prime}{sub LT} is related to the imaginary part of the longitudinal-transverse interference and therefore it vanishes in reactions proceeding through a channel with a single dominant mechanism. In quasifree nucleon knockout, the helicity asymmetry provides an unambiguous signature for the interference between direct knockout and rescattering amplitudes. The data were taken in April-May 1999 using polarized beams of energies between 2.2 and 4.4 GeV, with the CEBAF Large Acceptance Spectrometer (CLAS) detector located in Hall B at the Jefferson Laboratory, VA. The measured asymmetries compare well with the theoretical predictions.

  13. Seafloor Asymmetry in the Atlantic Ocean

    Measurements of seafloor asymmetry at about 360000 pairs of conjugate points along 1250 profiles across the mid-Atlantic Ridge(MAR)provide new constraints on models for the upwelling of the buoyant asthenosphere. The sign and amplitude of the asymmetry vary systematically and are functions of the distance between the spreading center and the location of the inferred location of maximum regional buoyancy(LMRB)in the asthenosphere. The LMRB is a smooth line derived from the observed asymmetry and is more centered at the regional topographic high than the spreading center. These observations are best explained by active upwelling of the underlying buoyant asthenosphere rather than by pressure-release melting.

    We investigate the consistency of a scenario in which the baryon asymmetry, dark matters, as well as the cosmic density perturbation are generated simultaneously through the evaporation of primordial black holes (PBHs). This scenario can explain the coincidence of the dark matter and the baryon density of the universe, and is free from the isocurvature perturbation problem. We show that this scenario predicts the masses of PBHs, right-handed neutrinos and dark matters, the Hubble scale during inflation, the non-gaussianity and the running of the spectral index. We also discuss the testability of the scenario by detecting high frequency gravitational waves from PBHs.

    This study investigated the tidal asymmetry imposed by both the interaction of principal tides and the higher harmonics generated by distortions within a tidal creek network with mixed mainly semidiurnal tide in the Bushehr Port, Persian Gulf. Since velocity and water-level imposed by principal triad tides K1-O1-M2 are in quadrature, duration asymmetries during a tidal period in this short, shallow inverse estuary should be manifest as skewed velocities. The principal tides produce periodic asymmetries including a strong ebb-dominance and a weak flood-dominance condition during spring and neap tides respectively. The higher harmonics induced by nonlinearities engender a flood-dominance condition where the convergence effects are higher than frictional effects, and an ebbdominance condition where intertidal storage are extended. Since the triad K1-O1-M2 driven asymmetry is not overcome by higher harmonics close to the mouth, the periodic asymmetry dominates within the creek in which higher harmonics reinforce the weak flood-dominance (strong ebb-dominance) condition in the convergent channel (divergent area). Also, the maximum flood and the maximum ebb from all harmonic constituents occurred close to high water slack time during both spring and neap tides in this short creek. Since occational wetting of intertidal areas happened close to the high water (HW) time during spring tide, the water level flooded slowly close to the HW time of the spring tide.

    The transversity distribution h1(x), which describes the transverse spin structure of quarks inside of transversely polarized protons, is only accessible through channels that couple h1(x) to another chiral odd distribution, such as the Collins fragmentation function (ΔD(z,kT)). Significant Collins asymmetries of charged pions have been observed in semi-inclusive deep inelastic scattering (SIDIS) data. These SIDIS asymmetries combined with e+e- process asymmetries from Belle have allowed for the extraction of h1(x) and ΔD(z ,kT). Uncertainties on h1(x) remain large due to the limited statistics and kinematic reach of the available data. In transversely polarized hadronic collisions, Collins asymmetries may be isolated and extracted by measuring the spin dependent azimuthal distributions of charged pions in jets. This presentation will show the first significant midrapditiy (| η | access higher momentum scales than the existing SIDIS data and will allow for a comprehensive study of evolution and factorization of the Collins channel.

    The transversity distribution (h1 x), which describes the transverse polarization of quarks in transversely polarized protons, is only accessible through channels that couple h1 x to another chiral odd distribution, such as the Collins fragmentation function (ΔN D z ,kT). Significant Collins asymmetries of charged pions have been observed in semi-inclusive deep inelastic scattering (SIDIS) data. These SIDIS asymmetries combined with e+e- process asymmetries from Belle and BaBar have allowed for the extraction of h1 x and ΔN D z ,kT . Uncertainties on h1 x remain large due to the limited statistics and kinematic reach of the available data. In transversely polarized hadronic collisions, Collins asymmetries may be isolated and extracted by measuring the spin dependent azimuthal distributions of charged pions in jets.

    The COMPASS Collaboration at CERN has measured the transverse spin azimuthal asymmetry of charged hadrons produced in semi-inclusive deep inelastic scattering using a 160 GeV μ+ beam and a transversely polarised NH3 target. The Sivers asymmetry of the proton has been extracted in the Bjorken x range 0.0030.03. The asymmetry is different from zero and positive also in the low x region, where sea-quarks dominate. The kinematic dependence of the asymmetry has also been investigated and results are given for various intervals of hadron and virtual photon fractional energy. In contrast to the case of the Collins asymmetry, the results on the Sivers asymmetry suggest a strong dependence on the four-momentum transfer to the nucleon, in agreement with the most recent calculations.

  20. Forward-backward and isospin asymmetry for B -> K* l+ l- decay in the standard model and in supersymmetry

    Feldmann, T; Feldmann, Thorsten; Matias, Joaquim

    2003-01-01

    We discuss two dedicated observables in exclusive B -> K* l+ l- decay that can be used to study effects of physics beyond the standard model, namely the forward-backward asymmetry in the lepton spectrum and the isospin-asymmetry between decays of charged and neutral B mesons. We consider the region of large recoil-energy (i.e. small invariant mass of the lepton pair), and employ the QCD factorization approach to exclusive B meson decays. Sub-leading effects in the heavy quark mass expansion have been taken into account for the calculation of the isospin-asymmetry. We give predictions for decay asymmetries in the standard model, and its supersymmetric extension with minimal flavor violation, using parameter values allowed by current experimental constraints on B->X_s gamma decay.

  1. Introduction "Workplace (a)symmetries: multimodal perspectives"

    DEFF Research Database (Denmark)

    Asmuss, Birte

    Following the seminal work on talk at work (Drew and Heritage, 1992) and later studies on interaction in institutional interaction (Arminen, 2005; Asmuß & Svennevig, 2009; Svennevig 2012a), the panel seeks to pursue the role of interactional micro-practices for the emergence of workplace symmetries...... and asymmetries. Workplaces are settings where different kinds of (a)symmetries are constructed through interaction ((Svennevig, 2012b, Asmuß, 2008). In comparison to interactions between professionals and laypeople, identities in workplace interactions where colleagues interact with each other may be...... more complex due to multiple roles and team alliances (Pomerantz & Denvir, 2007; Djordjilovic, 2012). Thus, participants of workplace interaction have to negotiate their position in a dynamically fluctuating network of symmetries and asymmetries. The emergence of symmetries and asymmetries in talk has...

  2. Leptogenesis and gravity: baryon asymmetry without decays

    CERN Document Server

    McDonald, J I

    2016-01-01

    A popular class of theories attributes the matter-antimatter asymmetry of the Universe to CP-violating decays of super-heavy BSM particles in the Early Universe. Recently, we discovered a new source of leptogenesis in these models, namely that the same Yukawa phases which provide the CP violation for decays, combined with curved-spacetime loop effects, lead to an entirely new gravitational mechanism for generating an asymmetry, driven by the expansion of the Universe and independent of the departure of the heavy particles from equilibrium. In this Letter, we build on previous work by analysing the full Boltzmann equation, exploring the full parameter space of the theory and studying the time-evolution of the asymmetry. Remarkably, we find regions of parameter space where decays play no part at all, and where the baryon asymmetry of the Universe is determined solely by gravitational effects.

    2014-01-01

    We study in detail the impact of anomalous Higgs couplings in angular asymmetries of the crossing-symmetric processes H --> Zl+l- and e+e- --> HZ. Beyond Standard Model physics is parametrized in terms of the SU(3)xSU(2)_LxU(1)_Y dimension-six effective Lagrangian. In the light of present bounds on d = 6 interactions we study how angular asymmetries can reveal non-standard CP-even and CP-odd couplings. We provide approximate expressions to all observables of interest making transparent their dominant dependence on anomalous couplings. We show that some asymmetries may reveal BSM effects that are hidden in other observables. In particular, CP-even and CP-odd d = 6 HZgamma couplings as well as (to a lesser extent) HZll contact interactions can generate asymmetries at the several percent level, while having small or no effects on the di-lepton invariant mass spectrum of H --> Zl+l-. Finally, the higher di-lepton invariant mass probed in e+e- --> HZ leads to interesting differences in the asymmetries with respect...

    Large parity-violating longitudinal single-spin asymmetries A(L)(e+) = -0.86(-0.14) (+0.30) and A(L)(e-) = 0.88(-0.71) (+0.12) are observed for inclusive high transverse momentum electrons and positrons in polarized p+p collisions at a center-of-mass energy of sqrt[s] = 500 GeV with the PHENIX detector at RHIC. These e± come mainly from the decay of W± and Z0 bosons, and their asymmetries directly demonstrate parity violation in the couplings of the W± to the light quarks. The observed electron and positron yields were used to estimate W± boson production cross sections for the e± channels of σ(pp → W+ X) × BR(W+ → e+ ν(e)) = 144.1 ± 21.2(stat)(-10.3) (+3.4) (syst) ± 21.6(norm)  pb, and σ(pp → W- X) × BR(W- → e- ν[over ¯](e)) = 31.7 ± 12.1(stat)(-8.2) (+10.1) (syst) ± 4.8(norm)  pb.

    We often observe disproportionate reactions to tangible information in large stock price movements. Moreover these movements feature an asymmetry: the number of crashes is more than that of frenzies in the S&P 500 index. This paper offers an explanation for these two characteristics of large movements in which hedging (portfolio insurance) causes amplified price reactions to news and liquidity shocks as well as an asymmetry biased towards crashes. Risk aversion of traders is shown to be essen...

    Evidence from hedging practices suggests that firms will hedge only if they expect that unfavorable events will arise. In markets with a significant degree of information asymmetry in which hedgers are oligopolists with superior knowledge concerning supply and demand, such as oil and gas futures, we contend that these companies will selectively hedge price movements, causing sharp price adjustments upon resolution of information asymmetry. Using aggregate analysts' surprise as a proxy for the...

Mechanisms of corporate governance include the characteristics of the board of directors. Our results seem to indicate a significant relationship between certain mechani...

  8. The strange asymmetry of the proton sea

    International Nuclear Information System (INIS)

    We present a phenomenologically motivated parameterization of the s and s-bar parton distribution functions in the proton, calculated in the framework of the Meson Cloud Model. Parameters of the model have been fixed by comparing to a recent parameterization of the strange asymmetry of the proton sea, which has emerged from a global fit to Deep Inelastic Scattering data. The model reproduces quite well the the asymmetry of the strange sea of the proton.

    This paper examines the role of asymmetry in all-pay auctions. In particular, this paper decomposes a change in players' valuations into the absolute change and the relative change, and analyzes how these changes a¢çect total expenditures. An increase in the sum of players' valuations increases total expenditures but an increase in asymmetry among players' valuations tends to decrease total expenditures both under complete and incomplete information.

    Hemispheric differences in the structure and dynamics of the polar regions of the thermosphere and ionosphere are caused by seasonal/latitudinal asymmetries of solar insolation acting in addition to the effects of the distinctive asymmetries of the main geomagnetic field. Viewing the earth from a satellite, the longitudinal and universal time variations of the thermosphere and ionosphere are far more spectacular in the southern polar thermosphere and ionosphere than in the northern polar regi...

    Core collapse supernovae are dominated by weakly interacting neutrinos. This provides a unique opportunity for macroscopic parity violation. We speculate that parity violation in a strong magnetic field can lead to an asymmetry in the explosion and a recoil of the newly formed neutron star. We estimate the asymmetry from neutrino-polarized-neutron elastic scattering, polarized electron capture and neutrino-nucleus elastic scattering in a (partially) polarized electron gas.

    We use the general formalism of squeezed rotated states to calculate baryon asymmetry in the wake of inflation through parametric amplification. We base our analysis on a B and CP violating Lagrangian in an isotropically expanding universe. The B and CP violating terms originate from the coupling of complex fields with non-zero baryon number to a complex background inflaton field. We show that a differential amplification of particle and anti-particle modes gives rise to baryon asymmetry.

    We propose a unified scenario to generate the masses of Dirac neutrinos and cold dark matter at the TeV scale, understand the origin of dark energy and explain the matter-antimatter asymmetry of the universe. This model can lead to significant impact on the Higgs searches at LHC.

  14. Particle dynamics in asymmetry-induced transport

    International Nuclear Information System (INIS)

    The particle dynamics of asymmetry-induced transport are studied using a single-particle computer simulation. For the case of a helical asymmetry with axial and azimuthal wavenumbers (k,l) and with periodic boundary conditions, behaviors consistent with analytical theory are observed. For the typical experimental case of a standing wave asymmetry, the code reveals dynamical behaviors not included in the analytical theory of this transport. The resonances associated with the two constituent helical waves typically overlap and produce a region of stochastic motion. In addition, particles near the radius where the asymmetry frequency ω matches l times the ExB rotation frequency ωR can be trapped in the potential of the applied asymmetry and confined to one end of the device. Both behaviors are associated with large radial excursions and mainly affect particles with low velocities, i.e., vzT/k, where ωT is the trapping frequency. For the case of a helical asymmetry with specularly reflecting boundaries, large radial excursions are observed for all velocities near the radius, where ω=lωR. Minor modifications to these results are observed when the code is run with realistic end potentials

    Full Text Available Occasionally, the expected effects of approach-avoidance motivation on anterior EEG alpha asymmetry fail to emerge, particularly in studies using affective picture stimuli. These null findings have been explained by insufficient motivational intensity of, and/or overshadowing interindividual variability within the responses to emotional pictures. These explanations were systematically tested using data from 70 students watching 5 types of affective pictures ranging from very pleasant to unpleasant. The stimulus categories reliably modulated self-reports as well as the amplitude of late positive potential, an ERP component reflecting orienting towards motivationally significant stimuli. The stimuli did not, however, induce expected asymmetry effects either for the sample or individual participants. Even while systematic stimulus-dependent individual differences emerged in self-reports as well as LPP amplitudes, the asymmetry variability was dominated by stimulus-independent interindividual variability. Taken together with previous findings, these results suggest that under some circumstances anterior asymmetry may not be an inevitable consequence of core affect. Instead, state asymmetry shifts may be overpowered by stable trait asymmetry differences and/or stimulus-independent yet situation-dependent interindividual variability, possibly caused by processes such as emotion regulation or anxious apprehension.

    Animals commonly use their limbs as signals and weapons during territorial aggression. Asymmetries of limb performance that do not relate to asymmetries of limb size (cryptic asymmetry) could substantially affect disputes, but this phenomenon has not been considered beyond primates. We investigated cryptic asymmetry in male crayfish (Cherax dispar), which commonly use unreliable signals of strength during aggression. Although the strength of a chela can vary by an order of magnitude for a given size, we found repeatable asymmetries of strength that were only weakly related to asymmetries of size. Size-adjusted strength of chelae and the asymmetry of strength between chelae were highly repeatable between environmental conditions, suggesting that asymmetries of strength stemmed from variation in capacity rather than motivation. Cryptic asymmetry adds another dimension of uncertainty during conflict between animals, which could influence the evolution of unreliable signals and morphological asymmetry. PMID:22417793
