Λ flow in heavy-ion collisions: The role of final-state interactions

Lambda flow in Ni+Ni collisions at SIS energies is studied in the relativistic transport model (RVUU 1.0). It is found that for primordial lambdas the flow is considerably weaker than proton flow. The inclusion of final-state interactions, especially the propagation of lambdas in the mean-field potential, brings the lambda flow close to that of protons. An accurate determination of the lambda flow in heavy-ion experiments is shown to be very useful for studying lambda properties in dense matter. copyright 1996 The American Physical Society

Final-state interaction and screening have a great influence on {ital q{anti q}} production cross sections, which are important quantities in many problems in quark-gluon plasma physics. They lead to an enhancement of the cross section for a {ital q{anti q}} color-singlet state and a suppression for a color-octet state. The effects are large near the production threshold. The presence of screening gives rise to resonances for {ital q{anti q}} production just above the threshold at specific plasma temperatures. These resonances, especially {ital c{anti c}} and {ital b{anti b}} resonances, may be utilized to search for the quark-gluon plasma by studying the temperature dependence of heavy-quark pair production just above the threshold.

Final state interactions in electron induced trinucleon breakup reactions

International Nuclear Information System (INIS)

Meijgaard, E. van.

1989-01-01

This thesis presents an exact analysis of the electromagnetic breakup process of a trinucleon system. The one-photon exchange mechanism is reviewed. The relevant components of the nuclear current are discussed and the off-shell one-body current matrix elements are derived to accommodate the evaluation of the trinucleon nuclear structure functions. The Faddeev equations are introduced. To facilitate the numerical evaluations the unitary pole expansion (UPE) is employed to describe a local S-wave spin-dependent interaction in a series of separable potential terms. The UPE convergence properties for the trinucleon bound state as well as for the N-N and N-d scattering observables are investigated. In view of the electromagnetic two-body and three-body breakup analysis the half off-shell wave functions for 3N→Nd and 3N→3N scattering are calculated. The nuclear structure functions of the electromagnetic two-body breakup structure functions of the electromagnetic two-body breakup processes are derived and exactly calculated. Results are presented and discussed for several kinetamic configurations. The nuclear response functions of the trinucleon breakup processes are calculated for a momentum transfer Q = 400 MeV/c. The results are compared with recent experimental data for the longitudinal and transverse response of both trinucleon systems. The three-body contributions to the response functions result from an essentially fourfold numerical integration of the invariant electromagnetic three-body breakup amplitude. A detailed derivation of this amplitude is presented and the treatment of the subsequent integration is discussed. An extension is formulated to include D-state components in the trinucleon bound state as well as in the disconnected final state components for the two-body breakup process. One kinematic situation is studied with the D-state extension. For the three-body breakup processes only the PWIA response is determined with the D-state component in the

Model-Independent Analysis of the Neutron-Proton Final-State Interaction Region in the $\\pi\\pi \\to pn\\pi^+$ Reaction

2001-01-01

Experimental data on the \\pi\\pi\\to pn\\pi^+ reaction measured in an exclusive two-arm experiment at 800 MeV show a narrow peak arising from the strong proton-neutron final-state interaction. It was claimed, within the framework of a certain model, that this peak contained up to a 25 % spin-singlet final-state contribution. By comparing the data with those of \\pi\\pi\\to d\\pi^+ in a largely model-independent way, it is here demonstrated that at all the angles measured the whole of the peak could be explained as being due to spin-triplet final states, with the spin-singlet being at most a few percent. Good qualitative agreement with the measured proton analysing power is also found within this approach.

A final state interaction model for K and eta decay into three pions

International Nuclear Information System (INIS)

Angus, A.G.

1973-07-01

The Khuri-Treiman model is adapted in a relativistic formalism with the electromagnetic mass differences of the pions in the final state taken into account to produce new predictions for the relative decay rates and the slope parameters of the four reactions K→3x and the two reactions eta→3x. The pion-pion interaction is investigated in terms of the N/D method and as well as the normal pure pole approximations for the N functions. The Khuri-Treiman equations are solved for the best solutions from both the pure pole and the mixed pole and cut models. (author)

Final-state interaction in spin asymmetry and GDH sum rule for incoherent pion production on the deuteron

International Nuclear Information System (INIS)

Darwish, E.M.; Arenhoevel, H.; Schwamb, M.

2003-01-01

The contribution of incoherent single-pion photoproduction to the spin response of the deuteron, i.e., the asymmetry of the total photoabsorption cross-section with respect to parallel and antiparallel spins of photon and deuteron, is calculated over the region of the Δ-resonance with inclusion of final-state NN and πN rescattering. Sizeable effects, mainly from NN rescattering, are found leading to an appreciable reduction of the spin asymmetry. Furthermore, the contribution to the Gerasimov-Drell-Hearn integral is explicitly evaluated by integration up to a photon energy of 550 MeV. Final-state interaction reduces the value of the integral to about half of the value obtained for the pure impulse approximation. (orig.)

Initial and Final State Interaction Effects in Small-x Quark Distributions

Energy Technology Data Exchange (ETDEWEB)

Xiao, Bo-Wen; Yuan, Feng

2010-08-30

We study the initial and final state interaction effects in the transverse momentum dependent parton distributions in the small-x saturation region. In particular, we discuss the quark distributions in the semi-inclusive deep inelastic scattering, Drell-Yan lepton pair production and dijet-correlation processes in pA collisions. We calculate the quark distributions in the scalar-QED model and then extend to the color glass condensate formalism in QCD. The quark distributions are found universal between the DIS and Drell-Yan processes. On the other hand, the quark distribution from the qq'-->qq' channel contribution to the dijet-correlation process is not universal. However, we find that it can be related to the quark distribution in DIS process by a convolution with the normalized unintegrated gluon distribution in the CGC formalism in the large Nc limit.

Effect of the final-state interaction on the initial core-hole lifetime: the case of the 4s-hole lifetime of Sn metal

International Nuclear Information System (INIS)

Ohno, Masahide

2003-01-01

The first theoretical study of the effect of the final-state interaction on the initial core-hole lifetime is presented. The 4s-hole lifetime width of Sn metal is calculated by an ab-initio atomic many-body theory (Green's function method). When the final-state interaction in the 4p4d two-hole state, created by the 4s -1 -4p -1 4d -1 εf super Coster-Kronig (CK) transition of the initial 4s hole, is explicitly taken into account, the ab-initio atomic many-body calculation of the 4s-hole X-ray photoelectron spectroscopy (XPS) spectrum of Sn atom can provide excellent agreement with experiment in both the 4s-hole energy and the 4s-hole lifetime width. Otherwise, the many-body calculation underestimates considerably the 4s-hole lifetime width. The 4p4d two-hole state interacts strongly with the 4d triple-hole state by the 4p -1 4d -1 -4d -3 εf super CK transition. The interaction affects greatly the initial 4s-hole lifetime width

Multimuon final states in high energy muon interactions

Multimuon final states observed in the MSU-Fermilab deep inelastic muon scattering apparatus are presented. These events, observed at both 150 and 275-GeV, are more numerous and the extra muons have qualitative different production characteristics than muons expected from conventional sources. Origin of these events are examined. The implication of the data on the understanding of scaling violation observed in muon scattering is discussed. (orig.) [de

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

Relativistic analysis of four-body final states

International Nuclear Information System (INIS)

Adhikari, S.K.

1977-01-01

The constraints of unitarity and analyticity on four-body final states are studied. It is shown that unitarity alone forces the amplitudes to be coherent and have singular behaviour. The implementation of unitarity with total energy analyticity yields a set of relativistic linear integral equations for the four-body amplitude. This is the minimal set consistent with quantum mechanics and also is the full dynamical set of equations with two-body separable interactions. These equations will provide important ingredients for the phenomenological analysis of four-body final states using the isobar model. (Auth.)

1991-01-01

FIRST is a computer program to generate final states from high energy hadronic interactions using the Monte Carlo technique. It is based on a theoretical model in which the high degree of universality in such interactions is related with the existence of highly excited quark-antiquark bound states, called fire-strings. The program handles the decay of both fire-strings and unstable particles produced in the intermediate states. (orig.)

New Perspectives for Hadron Phenomenology:The Effects of Final-State Interactions and Near-Conformal Effective QCD Couplings

Energy Technology Data Exchange (ETDEWEB)

Brodsky, S

2003-10-24

The effective QCD charge extracted from {tau} decay is remarkably constant at small momenta, implying the near-conformal behavior of hadronic interactions at small momentum transfer. The correspondence of large-N{sub c} supergravity theory in higher-dimensional anti-de Sitter spaces with gauge theory in physical space-time also has interesting implications for hadron phenomenology in the conformal limit, such as constituent counting rules for hard exclusive processes. The utility of light-front quantization and lightfront Fock wavefunctions for analyzing such phenomena and representing the dynamics of QCD bound states is reviewed. I also discuss the novel effects of initial- and final-state interactions in hard QCD inclusive processes, including Bjorken-scaling single-spin asymmetries and the leading-twist diffractive and shadowing contributions to deep inelastic lepton-proton scattering.

Multimuon final states have been detected by 3 experiments in the interactions of the muon beams of CERN (280 GeV) and FNAL (210 GeV) with heavy targets. For the first time production of J/PSI (3100) by space-like photons has been observed and its dependence on ν, Q 2 and t compared to Vector Dominance and photon-gluon fusion models. Also a clear signal has been seen for 3μ above QED tridents (outside J/PSI mass range) and 2μ events which are well described by charm production. An upper limit for the production of the T by high energy muons has been set

Final State Interaction Effects on the B + → J / ψ ρ + Decay

Directory of Open Access Journals (Sweden)

Behnam Mohammadi

2012-01-01

Full Text Available The exclusive decay of B + → J / ψ ρ + is studied in the framework of the QCD factorization (QCDF method and final state interaction (FSI. A direct B + → J / ψ ρ + decay is only occurred via a tree and a penguin based on the quark diagram analysis. The result that is found by using the QCDF method is less than the experimental result, so, the role of FSI is considered. The intermediate states D + D ̅ 0 , D + * D ̅ 0 * , D + * D ̅ 0 , and D + D ̅ 0 * via the exchange of D - and D - * are contributed to the B + → J / ψ ρ + decay. The above intermediate states is calculated by using the QCDF method. In the FSI effects the results of our calculations depend on “η” as the phenomenological parameter. The range of this parameter are selected from 1 to 2. For the exchanged particles D - and D - * , it is found that if η = 1.58 ~ 1.83 is selected the numbers of the branching ratio are placed in the experimental range. The experimental branching ratio of B + → J / ψ ρ + decay is ( 5 ± 0.8 × 1 0 - 5 , and our prediction number is ( 1.42 ± 0.36 × 1 0 - 5 in the absence of FSI effects, and it becomes ( 4.2 ~ 5.8 × 1 0 - 5 when FSI contributions are taken into account.

Meson dynamics beyond the quark model: a study of final state interactions

A scalar glueball is predicted in the 1 GeV mass region. The present analysis is concerned with experimental evidence for such a state. Recent high statistics results on central dimeson production at the ISR enable the authors to perform an extensive new coupled channel analysis of I = O S-wave ππ and KK-bar final states. This unambiguously reveals three resonances in the 1 GeV region - S 1 (991), S 2 (988) and epsilon(900) - where the naive quark model expects just two. These new features are discussed including how they may be confirmed experimentally and their present interpretation. The S 1 (991) is a plausible candidate for the scalar glueball. Other production reactions are examined (heavy flavour decays and γγ reactions) which lead to the same final states. (author)

Revisiting final state interaction in charmless Bq→P P decays

Science.gov (United States)

Chua, Chun-Khiang

2018-05-01

Various new measurements in charmless Bu ,d ,s→P P modes, where P is a low lying pseudoscalar meson, are reported by Belle and LHCb. These include the rates of B0→π0π0, η π0, Bs→η'η', B0→K+K- and Bs0→π+π- decays. Some of these modes are highly suppressed and are among the rarest B decays. Direct C P asymmetries on various modes are constantly updated. It is well known that direct C P asymmetries and rates of suppressed modes are sensitive to final state interaction (FSI). As new measurements are reported and more data will be collected, it is interesting and timely to revisit the rescattering effects in Bu ,d ,s→P P states. We perform a χ2 analysis with all available data on C P -averaged rates and C P asymmetries in B¯u ,d ,s→P P decays. Our numerical results are compared to data and those from factorization approach. The quality of the fit is improved significantly from the factorization results in the presence of rescattering. The relations on topological amplitudes and rescattering are explored and they help to provide a better understanding of the effects of FSI. As suggested by U(3) symmetry on topological amplitudes and FSI, a vanishing exchange rescattering scenario is considered. The exchange, annihilation, u -penguin, u -penguin annihilation, and some electroweak penguin amplitudes are enhanced significantly via annihilation and total annihilation rescatterings. In particular, the u -penguin annihilation amplitude is sizably enhanced by the tree amplitude via total annihilation rescattering. These enhancements affect rates and C P asymmetries. Predictions can be checked in the near future.

Final state interactions in the Ds+→ωπ+ and Ds+→ρ0π+ decays

Fajfer, S.; Prapotnik, A.; Singer, P.; Zupan, J.

2003-01-01

We investigate the decay mechanisms in the D s + →ωπ + and D s + →ρ 0 π + transitions. The naive factorization ansatz predicts a vanishing amplitude for the D s + →ωπ + decay, while the D s + →ρ 0 π + decay amplitude does have an annihilation contribution also in this limit. Both decays can proceed through intermediate states of hidden strangeness, e.g. K,K*, which we estimate in this paper. These contributions can explain the experimental value for the D s + →ωπ + decay rate, which no longer can be viewed as a clean signature of the annihilation decay of D s + . The combination of the π(1300) pole dominated annihilation contribution and the internal K,K* exchange can saturate the present experimental upper bound on the D s + →ρ 0 π + decay rate, which is therefore expected to be within experimental reach. Finally, the proposed mechanism of hidden strangeness final state interactions constitutes only a small correction to the Cabibbo allowed decay rates D s →KK*,φπ, which are well described already in the factorization approximation

Interactions of 209- and 90-GeV muons within a magnetized-steel calorimeter have produced final states containing one, two, three, four, and five muons. Redundant systems of proportional and drift chambers, fully sensitive in the forward direction, maintained 9% dimuon-mass resolution and high acceptance for multimuon final states. The first data are presented on F 2 (x, Q 2 ) from charged lepton-nucleon scattering spanning a range in ln (ln, Q 2 ) comparable to that measured in high energy neutrino scattering. The muon data confirm the decrease of F 2 with rising Q 2 in the region 0.2 80% of the world sample of fully-reconstructed 3μ final states containing the J/psi(3100), the first determination of the psi polarization yields sigma/sub L//sigma/sub T/ = xi 2 Q 2 /m/sub psi/ 2 with xi 2 = 4.0/sub -2.1/ +5 4 , 2.6 standard deviations above the vector-dominance expectation. A sample of 35539 two-muon final states contains a small excess of high p/sub perpendicular to/ high-Q 2 same-sign pairs and sets limits on neutral heavy lepton production by right-handed currents. Two five-muon final states are observed, of which only one is the likely result of a pure QED process. A single event with four muons in the final state is interpreted as diffractive b anti b production with anti b → psiX → μ + μ - X and b → μ - anti ν/sub μ/X. 42 references

The spectator model is corrected due to scattering of particles in the final state. It is shown that the discrepancies between the data for γd→u 0 π + uu and γd→u 0 pn and the predictions from the spectator model are mainly due to the nucleon-nucleon scattering in the final state. By means of a generally used evaluation procedure for the experimental data it is shown that the reaction cross sections of γu→π 0 u and γu→ - p, which are obtained from the experiments with deuterons, are not very sensitive to these corrections will have no influence on conclusions concerning the exotic properties of the electromagnetic current

STABLE STATIONARY STATES OF NON-LOCAL INTERACTION EQUATIONS

KAUST Repository

FELLNER, KLEMENS

2010-12-01

In this paper, we are interested in the large-time behaviour of a solution to a non-local interaction equation, where a density of particles/individuals evolves subject to an interaction potential and an external potential. It is known that for regular interaction potentials, stable stationary states of these equations are generically finite sums of Dirac masses. For a finite sum of Dirac masses, we give (i) a condition to be a stationary state, (ii) two necessary conditions of linear stability w.r.t. shifts and reallocations of individual Dirac masses, and (iii) show that these linear stability conditions imply local non-linear stability. Finally, we show that for regular repulsive interaction potential Wε converging to a singular repulsive interaction potential W, the Dirac-type stationary states ρ̄ ε approximate weakly a unique stationary state ρ̄ ∈ L∞. We illustrate our results with numerical examples. © 2010 World Scientific Publishing Company.

We have calculated the contribution of the final state interaction to the ionization of the K-shell during the β - and β + decays. The contributions to the spectra of the β particles and to the total probability of the K shell ionization are obtained. The disagreement between the calculated values and the experimental data for the latter is shown to diminish strongly. The influence of the secondary electrons on the distribution is also determined. 27 refs.; 2 figs.; 2 tabs

Electron-deuteron deep-inelastic scattering with spectator nucleon tagging and final-state interactions at intermediate x

Science.gov (United States)

Strikman, M.; Weiss, C.

2018-03-01

We consider electron-deuteron deep-inelastic scattering (DIS) with detection of a proton in the nuclear fragmentation region ("spectator tagging") as a method for extracting the free neutron structure functions and studying their nuclear modifications. Such measurements could be performed at a future electron-ion collider (EIC) with suitable forward detectors. The measured proton recoil momentum (≲100 MeV in the deuteron rest frame) specifies the deuteron configuration during the high-energy process and permits a controlled theoretical treatment of nuclear effects. Nuclear and nucleonic structure are separated using methods of light-front quantum mechanics. The impulse approximation to the tagged DIS cross section contains the free neutron pole, which can be reached by on-shell extrapolation in the recoil momentum. Final-state interactions (FSIs) distort the recoil momentum distribution away from the pole. In the intermediate-x region 0.1 rest frame momenta ≲1 GeV , target fragmentation region). We construct a schematic model describing this effect, using final-state hadron distributions measured in nucleon DIS experiments and low-energy hadron scattering amplitudes. We investigate the magnitude of FSIs, their dependence on the recoil momentum (angular dependence, forward/backward regions), their analytic properties, and their effect on the on-shell extrapolation. We comment on the prospects for neutron structure extraction in tagged DIS with an EIC. We discuss possible extensions of the FSI model to other kinematic regions (large/small x ). In tagged DIS at x ≪0.1 FSIs resulting from diffractive scattering on the nucleons become important and require separate treatment.

Determination of nn scattering length from data on nn final state interaction in nd-breakup reaction

Full text: An experiment is proposed for the high-precision determination of the neutron-neutron scattering length investigating the nn final state interaction in the nd breakup reaction. The singlet pp and nn scattering lengths are very sensitive probes of the NN-interaction, and their difference is a direct measure of charge-symmetry breaking (CSB) of the nuclear force. However CSB is a small effect, and accurate values of the scattering lengths are needed for a theoretical analysis. The proton-proton scattering length is well known from pp-scattering data (a pp = -17.3± 0.4 fm), and its uncertainty is mainly due to a model-dependent procedure of removing Coulomb effects. The neutron-neutron scattering length is determined from the following processes n+d→p+n+n, π - + d → γ +n+n, d+d→ 2 He+n+n by investigating the kinematic region of the nn final-state interaction (FSI) where two neutrons fly with low relative energy. The results obtained by now are characterized by a significant uncertainty in values of a nn ; they are grouped near -16 and -19 fm [1,2], so even the sign of the difference a nn - a pp is uncertain. In this experiment neutron-neutron scattering length is determined by measuring the yield of the nd breakup reaction as a function of the relative energy ε nn =(E 1 +E 2 -2(E 1 E 2 ) 1/2 cosθ)/2 of two neutrons in the FSI region (two neutrons fly in a narrow angular cone) where nn-interaction is strongly revealed. The theory of reactions in 3N system predicts the ε nn dependence of the FSI cross section being sensitive to the value of a nn . The measurements will be made using the neutron channel RADEX at Moscow meson factory of the Institute for Nuclear Research. The momenta and angles of the two emitted neutrons and the energy of the proton will be measured for each breakup event. The measured dependence of the reaction yield on the relative energy of the two neutrons will be compared to results of the Monte Carlo simulation that includes

Deep inelastic final states

International Nuclear Information System (INIS)

Girardi, G.

1980-11-01

In these lectures we attempt to describe the final states of deep inelastic scattering as given by QCD. In the first section we shall briefly comment on the parton model and give the main properties of decay functions which are of interest for the study of semi-inclusive leptoproduction. The second section is devoted to the QCD approach to single hadron leptoproduction. First we recall basic facts on QCD log's and derive after that the evolution equations for the fragmentation functions. For this purpose we make a short detour in e + e - annihilation. The rest of the section is a study of the factorization of long distance effects associated with the initial and final states. We then show how when one includes next to leading QCD corrections one induces factorization breaking and describe the double moments useful for testing such effects. The next section contains a review on the QCD jets in the hadronic final state. We begin by introducing the notion of infrared safe variable and defining a few useful examples. Distributions in these variables are studied to first order in QCD, with some comments on the resummation of logs encountered in higher orders. Finally the last section is a 'gaullimaufry' of jet studies

Results from a 4π solid angle measurement of the reaction π + + 4 He→ppd at incident pion energies of T π + =70, 118, 162, 239, and 330 MeV are presented. Integrated cross sections are given for the final states with energetic deuterons (ppd) and (pd)p. The differential cross sections are described by a complete set of five independent variables and various other kinematic variables and compared to cascade and phase space models where deuterons were formed by a semiclassical pickup model. The data are investigated for signatures of initial and final state interactions: it is found that more than half of the (ppd) yield cannot be explained by these mechanisms. The remaining strength is reasonably well reproduced by 3N phase space models followed by pickup. (c) 2000 The American Physical Society

The general charge properties of the hadronic final state produced in μ + p and μ + d interactions at 280 GeV are investigated. Quark charge retention and local charge compensation is observed. The ratio F 2 n /F 2 p of the neutron to proton structure function is derived from the measurement of the average hadronic charge in μd interactions. (orig.)

Hadron final states in deep inelastic processes

International Nuclear Information System (INIS)

Bjorken, J.D.

1976-05-01

Lectures are presented dealing mainly with the description and discussion of hadron final states in electroproduction, colliding beams, and neutrino reactions from the point of view of the simple parton model. Also the space-time evolution of final states in the parton model is considered. It is found that the picture of space-time evolution of hadron final states in deep inelastic processes isn't totally trivial and that it can be made consistent with the hypotheses of the parton model. 39 references

Exotic Searches in Jet Final States with the ATLAS Detector

CERN Document Server

Gibson, Adam; The ATLAS collaboration

2011-01-01

We summarize searches for physics beyond the Standard Model with events containing jets in the final state in pp collision data recorded with the ATLAS detector. We consider up to 1.0 fb-1 od data at sqrt(s) = 7 TeV. The data are compared to Standard Model expectations with the goal of searching for new phenomena: heavey resonances, contact interactions and gravitationally-mediated effects in large extra dimensions, microscopic black holes.

Final State Interaction on non Mesonic Hyperon Weak Decay Spectra of Λ12C

International Nuclear Information System (INIS)

Gonzalez, I.; Rodriguez, O.; Deppman, A.; Duarte, S.; Krmpotic, F.

2011-01-01

In the present work, we study the one nucleon induced non mesonic hyperon weak decay (NMWD)(ΛΝ → ηΝ) on the Λ 12 C hypernuclei with corresponding transition rates given by Γ ρ ≡ Γ (Λρ → ηρ) and Γ η ≡ Γ (Λη → ηη) respectively. The whole nuclear process is described by using a connection of two models, one to describe the primary non mesonic weak decay in the nuclear environment and another one to follows the time evolution of the outgoing of nucleons from nuclear system, to consider the Final State Interaction (FSI). The Independent-Particle Shell-Model (IPSM) is used to depict the dynamic of the primary decay by mean of the exchange of π and + Κ mesons with usual parameterization. A time dependent multicolisional intranuclear cascade approach implemented on the CRISP (Collaboration Rio-Sao Paulo) code incorporates the FSI to the Γ η /Γ ρ ratio calculation and the behaviour of these value with the coulomb barrier as well as to the observable nucleon kinetic energy spectra and also to angular correlation determinations. Recent KEK and FINUDA experiments on one- and two-nucleon non mesonic weak decay (NMWD) spectra in Λ 12 C hypernuclei are analyzed theoretically and the effect of FSI is determined within our model scenery.

Stability of stationary states of non-local equations with singular interaction potentials

KAUST Repository

Fellner, Klemens

2011-04-01

We study the large-time behaviour of a non-local evolution equation for the density of particles or individuals subject to an external and an interaction potential. In particular, we consider interaction potentials which are singular in the sense that their first derivative is discontinuous at the origin.For locally attractive singular interaction potentials we prove under a linear stability condition local non-linear stability of stationary states consisting of a finite sum of Dirac masses. For singular repulsive interaction potentials we show the stability of stationary states of uniformly bounded solutions under a convexity condition.Finally, we present numerical simulations to illustrate our results. © 2010 Elsevier Ltd.

X-ray M4,5 Resonant Raman Scattering from La metal with final 4p hole: Calculations with 4p-4d-4f configuration interaction in the final state and comparison with the experiment

International Nuclear Information System (INIS)

Taguchi, M.; Braicovich, L.; Tagliaferri, A.; Dallera, C.; Giarda, K.; Ghiringhelli, G.; Brookes, N.B.; Borgatti, F.

2001-03-01

We consider the X-Ray Resonant Raman Scattering (RRS) in La in the whole M 4,5 region ending with a state with a 4p hole, along the sequence 3d 10 4f 0 →3d 9 4f 1 →3d 10 4p 5 4f 1 . The final state configuration mixes with that with two 4d holes i.e. 3d 10 4d 8 4f n+2 having almost the same energy. Thus RRS must be described by introducing final state Configuration Interaction (CI) between states with one 4p hole and with two 4d holes. This approach allows detailed experimental data on La-metal to be interpreted on the basis of a purely ionic approach. It is shown that the inclusion of CI is crucial and has very clear effects. The calculations with the Kramers-Heisenberg formula describe all measured spectral features appearing in the strict Raman regime i.e. dispersing with the incident photon energy. In the experiment also a nondispersive component is present when the excitation energy is greater than about 2 eV above the M 5 peak. The shape and position of this component is well accounted for by a model based on all possible partitions of the excitation energy between localised and extended states. However, the intensity of the nondispersive component is greater in the measurements, suggesting a rearrangement in the intermediate excited state. The comparison of ionic calculations with the metal measurements is legitimate, as shown by the comparison between the measurements on La-metal and on LaF 3 with M 5 excitation, giving the same spectrum within the experimental accuracy. Moreover, the experiment shows that the final lifetime broadening is much greater in the final states corresponding to lower outgoing photon energies than in the states corresponding to higher outgoing photon energies.

Black hole state evolution, final state and Hawking radiation

International Nuclear Information System (INIS)

Ahn, D

2012-01-01

The effect of a black hole state evolution on the Hawking radiation is studied using the final state boundary condition. It is found that the thermodynamic or statistical mechanical properties of a black hole depend strongly on the unitary evolution operator S, which determines the black hole state evolution. When the operator S is random unitary or pseudo-random unitary, a black hole emits thermal radiation as predicted by Hawking three decades ago. In particular, when the black hole mass of the final state vanishes, Hawking’s original result is retrieved. On the other hand, it is found that the emission of the Hawking radiation could be suppressed when the evolution of a black hole state is determined by the generator of the coherent state. Such a case can occur for some primordial black holes with Planck scale mass formed by primordial density fluctuations through the process of squeezing the zero-point quantum fluctuation of a scalar field. Those primordial black holes can survive until the present time and can contribute to cold dark matter. (paper)

A plane-wave final-state theory of ATI

International Nuclear Information System (INIS)

Parker, J.S.; Clark, C.W.

1993-01-01

A Fermi Golden Rule calculation of ionization cross-sections provides us with the simplest example of a plane-wave final-state theory. In this method the final (unbound) state is modeled as a plane wave, an approximation that generally gives best results in the high energy limit in which the affect of the atomic potential on the final state can be neglected. A cross-section is then calculated from the matrix element connecting the bound initial state with the final state. The idea of generalizing this method to model transitions among unbound states is credited to L.V. Keldysh, and a number of related formalisms have been proposed that are consistent with the general features of experimental data. Here we describe a plane-wave final-state model of ATI that is in the spirit of these theories, but differs significantly in its implementation and predictions. We will present a comparison of the predictions of the plane-wave model with those of a full numerical integration of the time-dependent Schrodinger equation for atomic hydrogen in a radiation field. The theory and the numerical integration give good qualitative agreement in their predictions of photoelectron spectra over about 14 orders of magnitude

We report on exclusive decays of B mesons into final states containing charmonium using data collected with the BABAR detector at the PEP-II storage rings. The charmonium states considered here are J/{psi}, {psi}(2S), and {chi}{sub c1}. Branching fractions for several exclusive final states, a measurement of the decay amplitudes for the B{sup 0} {yields} J/{psi} K* decay, and measurements of the B{sup 0} and B{sup +} masses are presented. All of the results we present here are preliminary.

Quantum state detection and state preparation based on cavity-enhanced nonlinear interaction of atoms with single photon

Science.gov (United States)

Hosseini, Mahdi

Our ability to engineer quantum states of light and matter has significantly advanced over the past two decades, resulting in the production of both Gaussian and non-Gaussian optical states. The resulting tailored quantum states enable quantum technologies such as quantum optical communication, quantum sensing as well as quantum photonic computation. The strong nonlinear light-atom interaction is the key to deterministic quantum state preparation and quantum photonic processing. One route to enhancing the usually weak nonlinear light-atom interactions is to approach the regime of cavity quantum electrodynamics (cQED) interaction by means of high finesse optical resonators. I present results from the MIT experiment of large conditional cross-phase modulation between a signal photon, stored inside an atomic quantum memory, and a control photon that traverses a high-finesse optical cavity containing the atomic memory. I also present a scheme to probabilistically change the amplitude and phase of a signal photon qubit to, in principle, arbitrary values by postselection on a control photon that has interacted with that state. Notably, small changes of the control photon polarization measurement basis by few degrees can substantially change the amplitude and phase of the signal state. Finally, I present our ongoing effort at Purdue to realize similar peculiar quantum phenomena at the single photon level on chip scale photonic systems.

Study of topological properties of point-shaped photon interactions by means of energy flows in hadronic final states at large transverse momenta

International Nuclear Information System (INIS)

Gapp, C.

1990-03-01

The pointlike γ-parton interactions in γ-proton reactions are evaluated in terms of energy-flows. Only charged particles in the forward hemisphere of the overall CM-system (i.e. χ F >> 0) are used. The pointlike processes should exhibit '2-jetlike' structures. To disentangle the pointlike component from hadronlike photon interactions hadron and photon induced interactions have been studied. The experiment was carried out by the WA69 collaboration using the facilities of the CERN-Ω spectrometer. Both datasets were recorded with identical detector setups in order to minimize systematic effects. A tagged photon beam with energies between 65 and 175 GeV and mixed hadron beams (π + /K + , π - /K - ) at fixed energies of 80 and 140 GeV were used. For high transverse momenta the pointlike interactions are calculable in QCD at lowest order (α.α s ). Since energy-flows depend on all final state particles a collective measure for the hardness of an event has been introduced (Σip 2 perpendicular to in eventplane ). Only the energy-flows from photoproduction give evidence for the presence of 2-jetlike processes. The hadron induced distributions are scaled in order to emulate the behaviour of a hadronlike photon. The difference between the photon and scaled hadroninduced distributions is compared to a Monte Carlo calculation of the pointlike processes. (orig.) [de

Singularities in four-body final-state amplitudes

International Nuclear Information System (INIS)

Adhikari, S.K.

1978-01-01

Like three-body amplitudes, four-body amplitudes have subenergy threshold singularities over and above total-energy singularities. In the four-body problem we encounter a new type of subenergy singularity besides the usual two- and three-body subenergy threshold singularities. This singularity will be referred to as ''independent-pair threshold singularity'' and involves pair-subenergy threshold singularities in each of the two independent pair subenergies in four-body final states. We also study the particularly interesting case of resonant two- and three-body interactions in the four-body isobar model and the rapid (singular) dependence of the isobar amplitudes they generate in the four-body phase space. All these singularities are analyzed in the multiple-scattering formalism and it is shown that they arise from the ''next-to-last'' rescattering and hence may be represented correctly by an approximate amplitude which has that rescattering

Electroproduction of associated two-body final states

International Nuclear Information System (INIS)

Harding, D.J.

1983-01-01

The Large Aperture Magnet Experiment at the Cornell Electron Synchrotron measured electron scattering in the region 2.98 2 and 0.5 2 2 . The 11.5 GeV extracted electron beam struck a liquid hydrogen target in an eight kilogauss magnetic field. The charged particles in the final state were tracked through the field by a multiwire proportional chamber system of 34 planes. A lead-scintillator shower counter triggered the experiment on detection of a scattered electron. Time-of-flight and water Cherenkov counters identified some of the final state hadrons. The data recorded on tape was then passed through computer programs which linked proportional chamber strikes into tracks, fit momenta to the tracks, applied particle identification algorithms, selected interesting events, and plotted histograms of invariant masses. All of this is described here in detail, with special attention to the front-end electronics and the track-finding program. Many specific final states were observed. The analysis presented here concentrates on the reaction γ/sub v/p→pπ + ππ 0 , with the final hadrons resulting from the decay of a two-body state. The states pω 0 and p eta 0 are measured. Limits are set for the production of Δ + + rho - , Δ + rho 0 , and Δp + . The conclusion the author draws is that hadron-like two-body processes are almost completely absent in virtual photon scattering in this kinematic region. Vector meson production, excitation of the nucleons, and the scattering of the photons directly from individual partons are the important processes

Competition between Final-State and Pairing-Gap Effects in the Radio-Frequency Spectra of Ultracold Fermi Atoms

International Nuclear Information System (INIS)

Perali, A.; Pieri, P.; Strinati, G. C.

2008-01-01

The radio-frequency spectra of ultracold Fermi atoms are calculated by including final-state interactions affecting the excited level of the transition and compared with the experimental data. A competition is revealed between pairing-gap effects which tend to push the oscillator strength toward high frequencies away from threshold and final-state effects which tend instead to pull the oscillator strength toward threshold. As a result of this competition, the position of the peak of the spectra cannot be simply related to the value of the pairing gap, whose extraction thus requires support from theoretical calculations

Formation of resonances with final state photons in two photon interactions, and development of calorimetric techniques

International Nuclear Information System (INIS)

Mir, R.

1986-07-01

In this thesis, resonances produced in two photon interactions were investigated with the TASSO detector at PETRA. The η ' and A 2 resonances were studied in a final state of charged pions and low energy photons. The couplings of these resonances to γγ were measured: Γ γγ (η ' (958)) 5.1±0.4(stat.)±0.65(syst.) Kev, Γ γγ (A 2 (1320)) 0.90±0.27(stat.)±0.16(syst.) Kev. A search for ι(1460) and η c (2980) was initiated. Upper limits on the γγ widths of these resonances times their branching ratio to the decay channel were obtained: Γ γγ (ι→γγ) x B(ι→ρ 0 γ) γγ (η c →γγ) x B(η c →η ' π + π - ) < 2.6 keV (95% C.L.). A proportional tubes electromagnetic calorimeter operating in the proportional mode was constructed. Tower readout was incorporated. The calorimeter gave an energy resolution of σ/E = 19%/√E. Large surface, thin Gap Chambers (TGC), were developed and constructed for the OPAL hadron pole-tip-calorimeter. The TGC operate in a high gain mode. They provide large signals for both pad and strip readout, without the need for amplification. To form a hadron calorimeter, ten chambers were interlaced with 8 cm thick iron slabs between them. An energy resolution of: σ/E = 105%/√E was obtained

Decays of J/psi (3100) to baryon final states

International Nuclear Information System (INIS)

Eaton, M.W.

1982-05-01

We present results for the decays of psi(3100) into baryon and hyperon final states. The sample studied here consists of 1.3 million produced psi decays. The decays into nonstrange baryons agree well with currently established results, but with better statistics. In addition, significant resonance formation in multibody final states is observed. The decay psi → anti ppγ, the first direct photon decay of the psi involving baryons in the final state, is presented and the theoretical implications of the decays are briefly explored. Several new decays of the psi involving strange baryons are explored, including the first observations of three body final states involving hyperons. The I-spin symmetry of the strong decay psi → baryons has clearly been observed. The reduced matrix elements for psi → B anti B are presented for final states of different SU(3) content. The B 8 anti B 8 results are in excellent agreement with the psi being an SU(3) singlet as are the results for psi → B 10 anti B 10 . We present the first evidence for the SU(3) violating decays of the type psi → B 8 anti B 10 + c.c.. Angular distributions for psi → B 8 anti B 8 are presented and compared with theoretical predictions. Statistics are limited, but the data tends to prefer other than a 1 + Cos 2 theta distribution

Final state effects in photoemission studies of Fermi surfaces

International Nuclear Information System (INIS)

Kurtz, Richard L; Browne, Dana A; Mankey, Gary J

2007-01-01

Photoelectron spectroscopy is one of the most important methods for extracting information about the Fermi surface (FS) of materials. An electron photoexcited from the FS is emitted from the crystal conserving the parallel momentum, k parallel , while the perpendicular momentum k perpendicular is reduced due to the surface potential barrier. A simple interpretation of the process assumes the final state is free-electron-like allowing one to 'map' the detected photoelectron back to its initial k momentum. There are multiple final state effects that can complicate the interpretation of photoelectron data and these effects are reviewed here. These can involve both energy and k broadening, which can give rise to shadow or ghost FS contours, scattering and final state diffraction effects that modify intensities, and matrix element effects which reflect the symmetries of the states involved and can be highly dependent on photon polarization. These matrix elements result in contours of photoelectron intensity that follow the dispersion in k-space of the initial state, the FS, and the final state. Locations where intensities go to zero due to matrix element and symmetry effects can result in gaps where FS contours 'disappear'. Recognition that these effects can play a significant role in determining the measured angular distributions is crucial in developing an informed model of where the FS contours actually lie in relation to measured intensity contours

Final state interactions in K → ππ decays: ΔI = 1/2 rule vs. ε{sup '}/ε

Energy Technology Data Exchange (ETDEWEB)

Buras, Andrzej J. [TUM Institute for Advanced Study, Garching (Germany); TU Muenchen, Physik Department, Garching (Germany); Gerard, Jean-Marc [Universite catholique de Louvain, Centre for Cosmology, Particle Physics and Phenomenology (CP3), Louvain-la-Neuve (Belgium)

2017-01-15

Dispersive effects from strong ππ rescattering in the final state interaction (FSI) of weak K → ππ decays are revisited with the goal to have a global view on their relative importance for the ΔI = 1/2 rule and the ratio ε{sup '}/ε in the standard model (SM). We point out that this goal cannot be reached within a pure effective (meson) field approach like chiral perturbation theory in which the dominant current-current operators governing the ΔI = 1/2 rule and the dominant density-density (four-quark) operators governing ε{sup '}/ε cannot be disentangled from each other. But in the context of a dual QCD approach, which includes both long-distance dynamics and the UV completion, that is, QCD at short-distance scales, such a distinction is possible. We find then that beyond the strict large N limit, N being the number of colours, FSIs are likely to be important for the ΔI = 1/2 rule but much less relevant for ε{sup '}/ε. The latter finding diminishes significantly hopes that improved calculations of ε{sup '}/ε would bring its SM prediction to agree with the experimental data, opening thereby an arena for important new physics contributions to this ratio.

Photon final states at the Tevatron

Campanelli, Mario; /University Coll. London

2008-04-01

The authors present here several recent measurements involving associate production of photons and jets at the Tevatron. In particular, inclusive photon + met from D0, and photon + b-jets and photon + b-jet + leptons + MET from CDF are described in some detail. These measurements offer a good test of QCD predictions in rather complex final states.

Two- and quasi-two-body strange particle final state production in π+p interactions at low to intermediate energies

International Nuclear Information System (INIS)

Hanson, P.

1982-10-01

The two and quasi-two body final states Σ + K + , Σ + K* (892) + , Σ*(1385) + K + , Σ(1385) + K*(892) + produced by neutral strangeness exchange in π + p interactions are studied using our own 1-3 GeV/c data, comprising the 14 incident momenta of a two million picture bubble chamber experiment, in combination with the world data on the same and related channels. Because low energy resonance formation is not strongly coupled to the Σ,Σ* production channels, at very modest incident momenta their dominant features are seen to be understandable in terms of high energy hypercharge exchange phenomenology. We find that Regge models fitted to data in the 10 to 20 GeV/c range adequately describe the Σ and Σ* channels down to within a few hundred MeV/c of threshold and out to large center of mass scattering angles, and that over the range of the available world data weak exchange degeneracy expectations for these reactions are at least qualitatively successful. We observe that the SU(2), SU(3) flavor symmetries successfully describe these hypercharge exchange processes and relate them to charge exchange via sum rules and equalities expressing flavor independence of the strong interaction; in particular, we derive and test on the available world data a mass broken SU(3) sum rule for π + p → K + Σ + , π - p → K 0 Λ, K - p → anti K 0 n and test over a wider range of momenta than before an earlier expression relating Σ* and Δ production. We also find at least qualitative agreement between quark model predictions for forward hypercharge exchange and the data, and we find that 90 0 hypercharge exchange cross sections also conform to the expectations of the quark constituent picture for hadrons

We review the state-of-the-art of Glauber-inspired models for estimating the distribution of the number of participating nucleons in pA and AA collisions. We argue that there is room for improvement in these model when it comes to the treatment of diffractive excitation processes, and present a new simple Glauber-like model where these processes are better taken into account. We also suggest a new way of using the number of participating, or wounded, nucleons to extrapolate event characteristics from pp collisions, and hence get an estimate of basic hadronic final-state properties in pA collisions, which may be used to extract possible nuclear effects. The new method is inspired by the Fritiof model, but based on the full, semi-hard multiparton interaction model of PYTHIA8.

Final state effects in liquid 4He: An experimental test

International Nuclear Information System (INIS)

Inelastic neutron scattering at high momentum transfers can provide direct information on the atomic momentum distribution n(p) when the Impulse Approximation (IA) is valid. In isotropic systems, the scattering in the IA is directly proportional to the longitudinal momentum distribution which is a function of a single scaling variable Y /triple bond/ (M/Q)(ω /minus/ ω/sub r/), where M is the mass of the scatterer, Q is the momentum transfer, and ω/sub r/ = Q 2 /2M is the recoiled energy. However, the experimentally attainable Q's are not large enough to reach the IA limit. Deviations from the IA due to final state scattering by neighboring atoms, known as final state effects, will distort the observed scattering from the IA prediction. Thus, an understanding of deviations from the IA is essential to accurate determination of n(p). Liquid helium provides an excellent testing ground for studying FSE in a dense, strongly interacting system for two reasons. First, theoretical calculations of the momentum distributions are available in both the normal liquid, and superfluid phases. These calculations are believed to be quite accurate, since they agree well with several other measured properties of the liquid. In addition, n(p) in the superfluid exhibits a very sharp feature, the Bose condensate peak, which should be very sensitive to FSE. Comparison of the predicted scattering obtained from the theoretical n(p) using the IA to the experimentally observed scattering can be used to study deviations due to FSE. 14 refs., 7 figs

A search for beyond the Standard Model physics using a final state with light and boosted muon pairs at CMS experiment

CERN Document Server

Castaneda Hernandez, Alfredo Martin

2017-01-01

A search for new physics phenomena is presented using a final state with multi-muons, the topology studied considers pairs of opposite sign muons (dimuons) with a low invariant mass and potentially produced far from the interaction point (displaced). Several beyond the Standard Model scenarios fit into this category, including those predicting Dark matter particles (i.e. dark photons) which weakly interact with SM particles via a kinetic mixing parameter and could have a non-negligible lifetime. Other scenario is the Next-to-Minimal Supersymmetric Standard Model (NMSSM) that extends the higgs sector introducing new light bosons that can decay to muon pairs. The data analyzed corresponds to the one collected by CMS experiment during 2015 using 13 TeV collision energy. This search constrains a large, previously unconstrained area of the parameter space for each mode and allows for an easy reinterpretation for new physics models with similar final state.

Multiproton final states in positive pion absorption below the Δ(1232) resonance

Inclusive cross sections for positive pion absorption leading to final states including two or more protons have been measured with a large solid angle detector for incident pion energies from 30 to 135 MeV for targets with A=2-208. The mass dependences for the inclusive (π + ,2p), (π + ,3p), and total absorption cross sections for multiproton final states were found to be proportional to A n with n≅0.5. These cross sections also were observed to have an energy dependence at energies below 150 MeV reflective of the importance of the Δ(1232) resonance, similar to that observed for πd→pp. The inclusive cross sections for (π + ,4p) were found to be less than 10 mb for all targets at all energies. Estimates were also obtained for cross sections for pion absorption leading to 2p1n and 3p1n final states. Quasideuteron absorption contributions increase slowly with A, and the energy dependence of those contributions mirrors that for πd→pp. The data obtained here for multiproton final states indicate that a significant fraction of absorption events, increasing with A, most likely arises from final states containing fewer than two protons.

Three- and four-jet final states in photoproduction at HERA

International Nuclear Information System (INIS)

Chekanov, S.; Derrick, M.; Magill, S.

2007-08-01

Three- and four-jet final states have been measured in photoproduction at HERA using the ZEUS detector with an integrated luminosity of 121 pb -1 . The results are presented for jets with transverse energy E jet T >6 GeV and pseudorapidity vertical stroke η jet vertical stroke 2 2 and the inelasticity 0.2≤y≤0.85 and in two mass regions defined as 25≤M nj nj ≥50 GeV, where M nj is the invariant mass of the n-jet system. The four-jet photoproduction cross section has been measured for the first time and represents the highest-order process studied at HERA. Both the three- and four-jet cross sections have been compared with leading-logarithmic parton-shower Monte Carlo models, with and without multi-parton interactions. The three-jet cross sections have been compared to an O(αα 2 s ) perturbative QCD calculation. (orig.)

Properties of hadronic final states in diffractive deep inelastic ep scattering at DESY HERA

International Nuclear Information System (INIS)

2002-01-01

Characteristics of the hadronic final state of diffractive deep inelastic scattering events ep→eXp were studied in the kinematic range 4 X 2 2 , 70 P <0.03 with the ZEUS detector at the DESY ep collider HERA using an integrated luminosity of 13.8 pb-1. The events were tagged by identifying the diffractively scattered proton using the leading proton spectrometer. The properties of the hadronic final state X were studied in its center-of-mass frame using thrust, thrust angle, sphericity, energy flow, transverse energy flow, and 'seagull' distributions. As the invariant mass of the system increases, the final state becomes more collimated, more aligned, and more asymmetric in the average transverse momentum with respect to the direction of the virtual photon. Comparisons of the properties of the hadronic final state with predictions from various Monte Carlo model generators suggest that the final state is dominated by qq-barg states at the parton level

Surface-state mediated three-adsorbate interaction: exact and numerical results and simple asymptotic expression

International Nuclear Information System (INIS)

Hyldgaard, Per; Einstein, T.L.

2003-01-01

The interaction energy of three adsorbates on a surface consists of the sum of the three-pair interactions plus a trio contribution produced primarily by interference of electrons which traverse the entire perimeter, d 123 , of the three-adsorbate cluster. Here, we investigate this three-adatom interaction when mediated by the isotropic Shockley surface-state band found on noble-metal (1 1 1) surfaces, extending work on pair interactions. Our experimentally testable result depends on the s-wave phase-shift, characterizing the standing-wave patterns seen in scanning-tunneling microscopy (STM) images. Compared with the adsorbate-pair interactions, and in contrast to bulk-mediated interactions, the trio contribution exhibits a slightly weaker amplitude and a slightly faster asymptotic envelope decay, d 123 -5/2 . It also has a different but well-defined oscillation period dependent on d 123 and little dependence on the shape of the cluster. We finally compare the asymptotic description with exact model calculations assuming short-range interactions, which are viable even in the non-asymptotic range (when not outweighed by bulk-mediated interactions)

Dynamics of interacting qubits coupled to a common bath: Non-Markovian quantum-state-diffusion approach

2011-01-01

Non-Markovian dynamics is studied for two interacting qubits strongly coupled to a dissipative bosonic environment. We derive a non-Markovian quantum-state-diffusion (QSD) equation for the coupled two-qubit system without any approximations, and in particular, without the Markov approximation. As an application and illustration of our derived time-local QSD equation, we investigate the temporal behavior of quantum coherence dynamics. In particular, we find a strongly non-Markovian regime where entanglement generation is significantly modulated by the environmental memory. Additionally, we study residual entanglement in the steady state by analyzing the steady-state solution of the QSD equation. Finally, we discuss an approximate QSD equation.

Closing the Wedge: Search Strategies for Extended Higgs Sectors with Heavy Flavor Final States

Gori, Stefania; Shah, Nausheen R.; Zurek, Kathryn M.

2016-01-01

We consider search strategies for an extended Higgs sector at the high-luminosity LHC14 utilizing multi-top final states. In the framework of a Two Higgs Doublet Model, the purely top final states ($t\\bar t, \\, 4t$) are important channels for heavy Higgs bosons with masses in the wedge above $2\\,m_t$ and at low values of $\\tan\\beta$, while a $2 b 2t$ final state is most relevant at moderate values of $\\tan \\beta$. We find, in the $t\\bar t H$ channel, with $H \\rightarrow t \\bar t$, that both single and 3 lepton final states can provide statistically significant constraints at low values of $\\tan \\beta$ for $m_A$ as high as $\\sim 750$ GeV. When systematics on the $t \\bar t$ background are taken into account, however, the 3 lepton final state is more powerful, though the precise constraint depends fairly sensitively on lepton fake rates. We also find that neither $2b2t$ nor $t \\bar t$ final states provide constraints on additional heavy Higgs bosons with couplings to tops smaller than the top Yukawa due to expec...

Propagation of the state change induced by external forces in local interactions

Lu, Jianjun; Tokinaga, Shozo

2016-10-01

This paper analyses the propagation of the state changes of agents that are induced by external forces applied to a plane. In addition, we propose two models for the behavior of the agents placed on a lattice plane, both of which are affected by local interactions. We first assume that agents are allowed to move to another site to maximise their satisfaction. Second, we utilise a model in which the agents choose activities on each site. The results show that the migration (activity) patterns of agents in both models achieve stability without any external forces. However, when we apply an impulsive external force to the state of the agents, we then observe the propagation of the changes in the agents' states. Using simulation studies, we show the conditions for the propagation of the state changes of the agents. We also show the propagation of the state changes of the agents allocated in scale-free networks and discuss the estimation of the agents' decisions in real state changes. Finally, we discuss the estimation of the agents' decisions in real state temporal changes using economic and social data from Japan and the United States.

The recent personality psychology literature has coined the name of personality states to refer to states having the same behavioural, affective and cognitive content (described by adjectives) as the corresponding trait, but for a shorter duration. The variability in personality states may be the reaction to specific characteristics of situations. The aim of our study is to investigate whether specific situational factors, that is, different configurations of face-to-face interactions, are predictors of variability of personality states in a work environment. The obtained results provide evidence that within-person variability in personality is associated with variation in face-to-face interactions. Interestingly, the effects differ by type and level of the personality states: adaptation effects for Agreeableness and Emotional Stability, whereby the personality states of an individual trigger similar states in other people interacting with them and complementarity effects for Openness to Experience, whereby the personality states of an individual trigger opposite states in other people interacting with them. Overall, these findings encourage further research to characterize face-to-face and social interactions in terms of their relevance to personality states.

High-$p_T$ multi-jet final states at ATLAS and CMS

CERN Document Server

Lange, Clemens

2016-01-01

The increase of the centre-of-mass energy of the Large Hadron Collider (LHC) to 13 TeV has opened up a new energy regime. Final states including high-momentum multi-jet signatures often dominate beyond standard model phenomena, in particular decay products of new heavy particles. While the potential di-photon resonance currently receives a lot of attention, multi-jet final states pose strong constraints on what physics model an observation could actually be described with. In this presentation, the latest results of the ATLAS and CMS collaborations in high transverse momentum multi-jet final states are summarised. This includes searches for heavy resonances and new phenomena in the di-jet mass spectrum, di-jet angular distributions, and the sum of transverse momenta in different event topologies. Furthermore, results on leptoquark pair production will be shown. A particular focus is laid on the different background estimation methods.

LHC searches for BSM resonances in l{sup +}l{sup −}, jj, tt̄,γγ and VV final states have so far not resulted in discovery of new physics. Current results set lower limits on mass scales of new physics resonances well into the O(1) TeV range, assuming that the new resonance decays dominantly to a pair of Standard Model particles. While the SM pair searches are a vital probe of possible new physics, it is important to re-examine the scope of new physics scenarios probed with such final states. Scenarios where new resonances decay dominantly to final states other than SM pairs, even though well theoretically motivated, lie beyond the scope of SM pair searches. In this paper we argue that LHC searches for (vector) resonances beyond two particle final states would be useful complementary probes of new physics scenarios. As an example, we consider a class of composite Higgs models, and identify specific model parameter points where the color singlet, electrically neutral vector resonance ρ{sub 0} decays dominantly not to a pair of SM particles, but to a fermionic top partner T{sub f1} and a top quark, with T{sub f1}→tZ. We show that dominant decays of ρ{sub 0}→T{sub f1}t in the context of Composite Higgs models are possible even when the decay channel to a pair of T{sub f1} is kinematically open. Our analysis deals with scenarios where both m{sub ρ} and m{sub T{sub f{sub 1}}} are of O(1) TeV, leading to highly boosted tt̄Z final state topologies. We show that the particular composite Higgs scenario we consider is discoverable at the LHC13 with as little as 30 fb{sup −1}, while being allowed by other existing experimental constraints.

Comment on "Measurements without probabilities in the final state proposal"

Cohen, Eliahu; Nowakowski, Marcin

2018-04-01

The final state proposal [G. T. Horowitz and J. M. Maldacena, J. High Energy Phys. 04 (2004) 008, 10.1088/1126-6708/2004/04/008] is an attempt to relax the apparent tension between string theory and semiclassical arguments regarding the unitarity of black hole evaporation. Authors Bousso and Stanford [Phys. Rev. D 89, 044038 (2014), 10.1103/PhysRevD.89.044038] analyze thought experiments where an infalling observer first verifies the entanglement between early and late Hawking modes and then verifies the interior purification of the same Hawking particle. They claim that "probabilities for outcomes of these measurements are not defined" and therefore suggest that "the final state proposal does not offer a consistent alternative to the firewall hypothesis." We show, in contrast, that one may define all the relevant probabilities based on the so-called ABL rule [Y. Aharonov, P. G. Bergmann, and J. L. Lebowitz, Phys. Rev. 134, B1410 (1964), 10.1103/PhysRev.134.B1410], which is better suited for this task than the decoherence functional. We thus assert that the analysis of Bousso and Stanford cannot yet rule out the final state proposal.

Calculation of free-energy differences from computer simulations of initial and final states

International Nuclear Information System (INIS)

Hummer, G.; Szabo, A.

1996-01-01

A class of simple expressions of increasing accuracy for the free-energy difference between two states is derived based on numerical thermodynamic integration. The implementation of these formulas requires simulations of the initial and final (and possibly a few intermediate) states. They involve higher free-energy derivatives at these states which are related to the moments of the probability distribution of the perturbation. Given a specified number of such derivatives, these integration formulas are optimal in the sense that they are exact to the highest possible order of free-energy perturbation theory. The utility of this approach is illustrated for the hydration free energy of water. This problem provides a quite stringent test because the free energy is a highly nonlinear function of the charge so that even fourth order perturbation theory gives a very poor estimate of the free-energy change. Our results should prove most useful for complex, computationally demanding problems where free-energy differences arise primarily from changes in the electrostatic interactions (e.g., electron transfer, charging of ions, protonation of amino acids in proteins). copyright 1996 American Institute of Physics

Entanglement and quantum state geometry of a spin system with all-range Ising-type interaction

Kuzmak, A. R.

2018-04-01

The evolution of an N spin-1/2 system with all-range Ising-type interaction is considered. For this system we study the entanglement of one spin with the rest spins. It is shown that the entanglement depends on the number of spins and the initial state. Also, the geometry of the manifold, which contains entangled states, is obtained. For this case we find the dependence of entanglement on the scalar curvature of the manifold and examine it for different numbers of spins in the system. Finally we show that the transverse magnetic field leads to a change in the manifold topology.

3p shakedown spectra of laser excited potassium atoms as well as direct 3p photoemission of ground state potassium have been studied. These two excitation schemes lead to the same final states and thereby provide a good basis for a detailed study of the 3p 5 (4s3d) 1 configurations of singly ionized potassium and the photoemission processes leading to these configurations. The comparison of direct photoemission from the ground state and conjugate shakedown spectra from 4p 1/2 laser excited potassium made it possible to experimentally determine the character of final states that are only weakly excited in the direct photoemission but have a much higher relative intensity in the shakedown spectrum. Based on considerations of angular momentum and parity conservation the excitation scheme of the final states can be understood

Three- and four-jet final states in photoproduction at HERA

2007-08-15

Three- and four-jet final states have been measured in photoproduction at HERA using the ZEUS detector with an integrated luminosity of 121 pb{sup -1}. The results are presented for jets with transverse energy E{sup jet}{sub T}>6 GeV and pseudorapidity vertical stroke {eta}{sup jet} vertical stroke <2.4, in the kinematic region given by the virtuality of the photon Q{sup 2}<1 GeV{sup 2} and the inelasticity 0.2{<=}y{<=}0.85 and in two mass regions defined as 25{<=}M{sub nj}<50 GeV and M{sub nj}{>=}50 GeV, where M{sub nj} is the invariant mass of the n-jet system. The four-jet photoproduction cross section has been measured for the first time and represents the highest-order process studied at HERA. Both the three- and four-jet cross sections have been compared with leading-logarithmic parton-shower Monte Carlo models, with and without multi-parton interactions. The three-jet cross sections have been compared to an O({alpha}{alpha}{sup 2}{sub s}) perturbative QCD calculation. (orig.)

The renormalization of collective states and the improper initial or final states in NFT

The collective lines in a given diagram are renormalized by including higher order processes. The problem is cast into the form of a conventional linear algebraic matrix equation that allows a simple treatment of the normalization conditions. It is shown that the states entering in the renormalization of the phonons become improper initial or final states, if dressed phonons are used in the intermediate states. A simple extension of this argument allows one to justify one of the rules given in the formulation of the NFT. (Auth.)

1997-01-01

This is the final report for the DOE-sponsored experimental particle physics program at Virginia Tech to study the properties of the Standard Model of strong and electroweak interactions. This contract (DE-AS05-80ER10713) covers the period from August 1, 1980 to January 31, 1993. Task B of this contract, headed by Professor Alexander Abashian, is described in this final report. This program has been pursued on many fronts by the researchers in a search for axions at SLAC, in electron-positron collisions in the AMY experiment at the TRISTAN collider in Japan, in measurements of muon decay properties in the MEGA and RHO experiments at the LAMPF accelerator, in a detailed analysis of scattering effects in the purported observation of a 17 keV neutrino at Oxford, in a search for a disoriented chiral condensate with the MiniMax experiment at Fermilab, and in an R ampersand D program on resistive plate counters that could find use in low-cost high-quality charged particle detection at low rates

2018-01-11

In the 2008 E-Area Performance Assessment (PA), each final disposal limit was constructed as the product of a preliminary disposal limit and a plume interaction factor. The following mathematical development demonstrates that performance objectives are generally expected to be satisfied with high confidence under practical PA scenarios using this method. However, radionuclides that experience significant decay between a disposal unit and the 100-meter boundary, such as H-3 and Sr-90, can challenge performance objectives, depending on the disposed-of waste composition, facility geometry, and the significance of the plume interaction factor. Pros and cons of analyzing single disposal units or multiple disposal units as a group in the preliminary disposal limits analysis are also identified.

Supramolecular interactions in the solid state

Directory of Open Access Journals (Sweden)

Giuseppe Resnati

2015-11-01

Full Text Available In the last few decades, supramolecular chemistry has been at the forefront of chemical research, with the aim of understanding chemistry beyond the covalent bond. Since the long-range periodicity in crystals is a product of the directionally specific short-range intermolecular interactions that are responsible for molecular assembly, analysis of crystalline solids provides a primary means to investigate intermolecular interactions and recognition phenomena. This article discusses some areas of contemporary research involving supramolecular interactions in the solid state. The topics covered are: (1 an overview and historical review of halogen bonding; (2 exploring non-ambient conditions to investigate intermolecular interactions in crystals; (3 the role of intermolecular interactions in morphotropy, being the link between isostructurality and polymorphism; (4 strategic realisation of kinetic coordination polymers by exploiting multi-interactive linker molecules. The discussion touches upon many of the prerequisites for controlled preparation and characterization of crystalline materials.

On-Demand Final State Control of a Surface-Bound Bistable Single Molecule Switch.

Modern electronic devices perform their defined action because of the complete reliability of their individual active components (transistors, switches, diodes, and so forth). For instance, to encode basic computer units (bits) an electrical switch can be used. The reliability of the switch ensures that the desired outcome (the component's final state, 0 or 1) can be selected with certainty. No practical data storage device would otherwise exist. This reliability criterion will necessarily need to hold true for future molecular electronics to have the opportunity to emerge as a viable miniaturization alternative to our current silicon-based technology. Molecular electronics target the use of single-molecules to perform the actions of individual electronic components. On-demand final state control over a bistable unimolecular component has therefore been one of the main challenges in the past decade (1-5) but has yet to be achieved. In this Letter, we demonstrate how control of the final state of a surface-supported bistable single molecule switch can be realized. On the basis of the observations and deductions presented here, we further suggest an alternative strategy to achieve final state control in unimolecular bistable switches.

Starting from a discussion of constraints on invariant variables a generalization of the so called Yang-variables is discussed for the case of 5 and 6 particles in the final states. The obtained Lorentz-invariant variables are ''quasi permutation invariant'' with respect to the final state particles. The influence of Gram determinants is discussed in the context of the application of a cluster algorithm. (author)

Final state effects in neutron Compton scattering measurements

International Nuclear Information System (INIS)

Fielding, A.L.

1997-10-01

The single atom momentum distributions of condensed matter systems can be derived using the technique of neutron Compton scattering (NCS). The electron Volt spectrometer (eVS) which is situated at the world's most intense pulsed neutron spallation source, ISIS, has been configured to perform NCS measurements. Interpretation of NCS data requires the use of the impulse approximation, however even at the high energy and momentum transfers obtainable on the eVS deviations from the impulse approximation occur. These deviations are generally known as final state effects (FSE) which manifest themselves as an asymmetry in the measured momentum distribution. The aim of the work reported in this thesis is to demonstrate how final state effects can be accounted for in a simple way using the expansion method described by Sears. An advantage of the Sears method is that the first asymmetric term in the expansion is proportional to the mean Laplacian of the potential, 2 V>, thus giving access to further information on the single atom potential. The Sears expansion has been incorporated into data analysis routines and applied to measured data on three systems that were chosen to represent the systems that are regularly investigated using the eVS. Measurements have been carried out on the deuteron in ZrD 2 , a light atom in a heavy lattice, beryllium, a polycrystalline solid and pyrolytic graphite, an aligned crystalline sample with an anisotropic momentum distribution. The study shows how the new analysis method gives more reliable values for the mean kinetic energy k >, which can be derived from the measured momentum distribution. A comparison of measured data with simulated data calculated within the harmonic approximation reveals how 2 V> can be a sensitive probe of anharmonicity of the interatomic potential. An anisotropy in the derived k > and 2 V> of pyrolytic graphite has been measured indicating the dependence of final state effects on bonding strength. The derived 2 V

Beyond Standard Model searches in jets plus missing transverse energy final states with the ATLAS experiment at the LHC

AUTHOR|(INSPIRE)INSPIRE-00414488; Alviggi, Mariagrazia; Conventi, Francesco

Dark Matter (DM) is currently one of the most challenging goal in the LHC programme: if DM exists it can be pair-produced in proton-proton collisions. Since its weakly-interacting nature, final signatures with high missing momentum and Standard Model (SM) particles are employed in these searches. This thesis presents results on signatures involving bottom quarks in final states, described in models where DM production occurs via massive spin-0 mediators (scalar or pseudoscalar) with a coupling to SM particles proportional to their masses. These collider searches provide an interesting complementarity to DM direct and indirect detection experiments, covering the parameter space with low DM masses. The results shown in the thesis are obtained on the data collected by the ATLAS experiment in 2015 and 2016.

Dark matter annihilation into four-body final states and implications for the AMS antiproton excess

Science.gov (United States)

Clark, Steven J.; Dutta, Bhaskar; Strigari, Louis E.

We consider dark matter annihilation into a general set of final states of standard model particles, including two-body and four-body final states that result from the decay of intermediate states. For dark matter masses ˜10 - 105 GeV , we use updated data from Planck and from high gamma-ray experiments such as Fermi-LAT, MAGIC, and VERITAS to constrain the annihilation cross section for each final state. The Planck constraints are the most stringent over the entire mass range for annihilation into light leptons, and the Fermi-LAT constraints are the most stringent for four-body final states up to masses ˜104 GeV . We consider these constraints in light of the recent AMS antiproton results, and show that for light mediators it is possible to explain the AMS data with dark matter, and remain consistent with Fermi-LAT Inner Galaxy measurements, for mχ˜60 - 100 GeV mass dark matter and mediator masses mϕ/mχ≲1 .

A first measurement is presented of the charge asymmetry in the hadronic final state from the hard interaction in deep-inelastic ep neutral current scattering at HERA. The measurement is performed in the range of negative squared four momentum transfer 100 2 2 . The difference between the event normalised distributions of the scaled momentum, x p , for positively and negatively charged particles, measured in the current region of the Breit frame, is studied together with its evolution as a function of Q. The results are compared to Monte Carlo models at the hadron and parton level. (orig.)

Study of GMSB models with photon final states using the ATLAS detector

Energy Technology Data Exchange (ETDEWEB)

Terwort, Mark

2009-11-30

Models with gauge mediated supersymmetry breaking (GMSB) provide a possible mechanism to mediate supersymmetry breaking to the electroweak scale. In these models the lightest-supersymmetric particle is the gravitino, while the next-to-lightest supersymmetric particle is either the lightest neutralino or a slepton. In the former case final states with large missing transverse energy from the gravitinos, multiple jets and two hard photons are expected in pp-collisions at the LHC. Depending on the lifetime of the neutralino the photons might not point back to the interaction vertex, which requires dedicated search strategies. Additionally, this feature can be used to measure the neutralino lifetime using either the timing information from the electromagnetic calorimeter or the reconstructed photon direction. Together with the measurements of kinematic endpoints in invariant mass distributions, the lifetime can be used as input for fits of the GMSB model and for the determination of the underlying parameters. The signal selection and the discovery potential for GMSB models with photons in the nal state are discussed using simulated data of the ATLAS detector. In addition, the measurement of supersymmetric particle masses and of the neutralino lifetime as well as the results of the global GMSB fits are presented. (orig.)

Interference between radiative emission and autoionization in the decay of excited states of atoms

International Nuclear Information System (INIS)

Armstrong, L. Jr.; Theodosiou, C.E.; Wall, M.J.

1978-01-01

An excited state of an atom which can autoionize can also undergo radiative decay. We consider the interaction between the final states resulting from these two modes of decay, and its effects on such quantities as the fluorescence yield of the excited state, excitation profile of the excited state, and the spectra of the emitted photons and electrons. It is shown that the fraction of decays of the excited state resulting in a photon (fluorescence yield) is particularly sensitive to the details of the final-state interaction. In lowest order in the final-state interaction, the fluorescence yield is increased by a factor (1 + 1/q 2 ) from the traditional value, where q is the Fano q parameter relating to the excited state and the final atomic state

Hadronic molecular states from the K anti K* interaction

In this work, the K anti K* interaction is studied in a quasipotential Bethe-Salpeter equation approach combined with the one-boson-exchange model. With the help of the hidden-gauge Lagrangian, the exchanges of pseudoscalar mesons (π and η) and vector mesons (ρ, ω and φ) are considered to describe the K anti K* interaction. Besides the direct vector-meson exchange which can be related to the Weinberg-Tomozawa term, pseudoscalar-meson exchanges also play important roles in the mechanism of the K anti K* interaction. The poles of scattering amplitude are searched to find the molecular states produced from the K anti K* interaction. In the case of quantum number I{sup G}(J{sup PC}) = 0{sup +}(1{sup ++}), a pole is found with a reasonable cutoff, which can be related to the f{sub 1}(1285) in experiment. Another bound state with 0{sup -}(1{sup +-}) is also produced from the K anti K* interaction, which can be related to the h{sub 1}(1380). In the isovector sector, the interaction is much weaker and a bound state with 1{sup +}(1{sup +}) relevant to the b{sub 1}(1235) is produced but at a larger cutoff. Our results suggest that in the hadronic molecular state picture the f{sub 1}(1285) and b{sub 1}(1235) are the strange partners of the X(3872) and Z{sub c}(3900), respectively. (orig.)

Exploring Market State and Stock Interactions on the Minute Timescale.

Directory of Open Access Journals (Sweden)

Lei Tan

Full Text Available A stock market is a non-stationary complex system. The stock interactions are important for understanding the state of the market. However, our knowledge on the stock interactions on the minute timescale is limited. Here we apply the random matrix theory and methods in complex networks to study the stock interactions and sector interactions. Further, we construct a new kind of cross-correlation matrix to investigate the correlation between the stock interactions at different minutes within one trading day. Based on 50 million minute-to-minute price data in the Shanghai stock market, we discover that the market states in the morning and afternoon are significantly different. The differences mainly exist in three aspects, i.e. the co-movement of stock prices, interactions of sectors and correlation between the stock interactions at different minutes. In the afternoon, the component stocks of sectors are more robust and the structure of sectors is firmer. Therefore, the market state in the afternoon is more stable. Furthermore, we reveal that the information of the sector interactions can indicate the financial crisis in the market, and the indicator based on the empirical data in the afternoon is more effective.

In particular, there is significant interest in understanding the fluctuations in the initial stage of a collision, how exactly these fluctuations are propagated through the system evolution, and how they are manifested in correlations between measured particles. In order to address these questions a workshop was organized on ‘initial state fluctuations and final state correlations’, held at ECT* in Trento, Italy during the week of 2–6 July 2012. The goal was to collect recent work in order to provide a coherent picture of the current status of our understanding, to identify important questions that remain open, and to set a course for future research. Here we report the outcome of the presentations and discussions, focusing on the most important conclusions. (comment)

Robustness of Greenbergerendash Horneendash Zeilinger and W states against Dzyaloshinskii-Moriya interaction

Science.gov (United States)

Sharma, Kapil K.; Pandey, S. N.

2016-12-01

In this article, the robustness of tripartite Greenberger-Horne-Zeilinger (GHZ) and W states is investigated against Dzyaloshinskii-Moriya (i.e. DM) interaction. We consider a closed system of three qubits and an environmental qubit. The environmental qubit interacts with any one of the three qubits through DM interaction. The tripartite system is initially prepared in GHZ and W states, respectively. The composite four qubits system evolve with unitary dynamics. We detach the environmental qubit by tracing out from four qubits, and profound impact of DM interaction is studied on the initial entanglement of the system. As a result, we find that the bipartite partitions of W states suffer from entanglement sudden death (i.e. ESD), while tripartite entanglement does not. On the other hand, bipartite partitions and tripartite entanglement in GHZ states do not feel any influence of DM interaction. So, we find that GHZ states have robust character than W states. In this work, we consider generalised GHZ and W states, and three π is used as an entanglement measure. This study can be useful in quantum information processing where unwanted DM interaction takes place.

Evidence for the Higgs boson decay to τ+τ- in the lepton+hadrons final state with ATLAS

International Nuclear Information System (INIS)

Schwindt, Thomas

2015-01-01

The data recorded with the ATLAS experiment during the first run period of the Large Hadron Collider are analysed by selecting final states with two τ-leptons, which further decay to a lighter lepton and to hadrons, respectively. The modelling of these final states is first validated in the context of the Z boson production cross section in ττ final states. The event selection and the data-driven techniques for the estimation of important background processes are then adapted to a search for H→ττ decays of the Higgs boson. In this search, Z→ττ final states contribute the dominant background and are therefore modelled in a data-driven way by replacing the Z decay products in Z→μμ data events with simulated decays of τ-leptons. Including all different background estimates, the search strategy is developed, and its sensitivity is documented in two intermediate results. With the final multi-variate analysis employing boosted decision trees, an excess of data over the estimated background in τ lep τ had final states is observed with a statistical significance of 3.2σ. It is compatible with a mass of m H ∼125 GeV, which has been measured in other final states originating from bosonic decays. This result is evidence for the Yukawa coupling of the Higgs boson to τ-leptons.

Exchange interactions in two-state systems: rare earth pyrochlores

Science.gov (United States)

Curnoe, S. H.

2018-06-01

The general form of the nearest neighbour exchange interaction for rare earth pyrochlores is derived based on symmetry. Generally, the rare earth angular momentum degeneracy is lifted by the crystal electric field (CEF) into singlets and doublets. When the CEF ground state is a doublet that is well-separated from the first excited state the CEF ground state doublet can be treated as a pseudo-spin of some kind. The general form of the nearest neighbour exchange interaction for pseudo-spins on the pyrochlore lattice is derived for three different types of pseudo-spins. The methodology presented in this paper can be applied to other two-state spin systems with a high space group symmetry.

Full Text Available Résumé The Compact Muon Solenoid (CMS collaboration has developed a complete program of searches beyond the Standard Model (SM covering a wide range of final states. This document focuses on searches in final states with photons and missing transverse energy ETmiss organised in three analyses. The first two include comparison of the ETmiss distribution (isolation sideband method in events with either at least two photons plus at least one hadronic jet, or at least one photon plus at least two hadronic jets. The third analysis corresponds to a new approach, the Jet-Gamma Balance (JGB method, for events with at least one photon plus at least three hadronic jets.We observe no significant deviations from the SM expectation and thus derive upper limits on the signal cross section at the 95% confidence level (CL for a range of squark, gluino and neutralino mass points in the Gauge Mediated Supersymmetry Breaking scenario.

The Interaction between Interoceptive and Action States within a Framework of Predictive Coding

Science.gov (United States)

Marshall, Amanda C.; Gentsch, Antje; Schütz-Bosbach, Simone

2018-01-01

The notion of predictive coding assumes that perception is an iterative process between prior knowledge and sensory feedback. To date, this perspective has been primarily applied to exteroceptive perception as well as action and its associated phenomenological experiences such as agency. More recently, this predictive, inferential framework has been theoretically extended to interoception. This idea postulates that subjective feeling states are generated by top–down inferences made about internal and external causes of interoceptive afferents. While the processing of motor signals for action control and the emergence of selfhood have been studied extensively, the contributions of interoceptive input and especially the potential interaction of motor and interoceptive signals remain largely unaddressed. Here, we argue for a specific functional relation between motor and interoceptive awareness. Specifically, we implicate interoceptive predictions in the generation of subjective motor-related feeling states. Furthermore, we propose a distinction between reflexive and pre-reflexive modes of agentic action control and suggest that interoceptive input may affect each differently. Finally, we advocate the necessity of continuous interoceptive input for conscious forms of agentic action control. We conclude by discussing further research contributions that would allow for a fuller understanding of the interaction between agency and interoceptive awareness. PMID:29515495

The Melt Vessel Interaction (MVI) project is concerned with the consequences of the interactions that a core melt, generated during a postulated severe accident in a light water reactor, may have with the pressure vessel. In particular, the issues concerned with the failure of the vessel bottom head are the focus of the research. The specific objectives of the project are to obtain data and develop validated models, which could be applied to prototypic plants, and accident conditions, for resolution of issues related to the melt vessel interactions. The project work has been performed by nine partners having varied responsibility. The work included a large number of experiments, with simulant materials, whose observations and results are employed, respectively, to understand the physical mechanisms and to develop validated models. Applications to the prototypic geometry and conditions have also been performed. This report is volume 1 of the Final Report for the Project, in which a summary of the progress achieved in the experimental program is provided. We have, however, included some aspects of the modeling activities. Volume 2 of the Final report describes the progress achieved in the modeling program. The progress achieved in the experimental and modeling parts of the Project has led to the resolution of some of the issues of melt vessel interaction. Considerable progress was also achieved towards resolution of the remaining issues

Brom, J.-M.

1978-01-01

The production of Drell-Yan pairs is studied, in reactions like h+h→1 + 1 - +X---, where the charged part of the associated final state is detected. The first part presents some theoretical aspects, relative to the Drell-Yan mechanism and to models dealing with the associated final state. The second part presents a possible experimental set-up in order to study this physics, based on vertex detection with fast electronic detectors, and makes estimations for the expected number of events. In the last part, is evaluated the pattern recognition program of the events where one pair of leptons is detected. The recognition program is analysed and presented its performance [fr

We calculate the decay widths of various C-even charmonium levels into the ω Φ final state. We show that this doubly OZI suppressed decay mode is not actually much smaller as compared to the ordinary ρ ρ mode. The branching ratios obtained are given. In connection with these decay modes, we discuss the deviations from the quark model U (3)-symmetry, the role of higher twists and that of power corrections in the charmonium region Q 2 ≅10 GeV 2

Stochastic final-state dynamics of widening entanglement-a possible description of quantum measurement

International Nuclear Information System (INIS)

Eriksson, Karl-Erik

2009-01-01

The measurement process of quantum mechanics is analysed in the scattering theory of quantum field theory. A matrix of bilinear forms of the scattering amplitudes (the R-matrix) is used as the basic descriptive tool. The measurement process is viewed as a final-state interaction described through a series of linear stochastic mappings of the R-matrix, not changing the observable to be measured. The unknown details of the measurement apparatus enter through the stochasticity of the mappings. Although linear in terms of the R-matrix, the mappings are nonlinear in the density matrix, which is obtainable from the R-matrix through normalization. The eigenstates of the observable are the attractors of the mapping process. This result, known from previous generalizations of quantum mechanics, is obtained here within linear quantum mechanics. The conclusion is that the measurement process can be understood within relativistic quantum field theory itself without any generalization or metatheory.

Motivational state controls the prediction error in Pavlovian appetitive-aversive interactions.

Science.gov (United States)

Laurent, Vincent; Balleine, Bernard W; Westbrook, R Frederick

2018-01-01

Contemporary theories of learning emphasize the role of a prediction error signal in driving learning, but the nature of this signal remains hotly debated. Here, we used Pavlovian conditioning in rats to investigate whether primary motivational and emotional states interact to control prediction error. We initially generated cues that positively or negatively predicted an appetitive food outcome. We then assessed how these cues modulated aversive conditioning when a novel cue was paired with a foot shock. We found that a positive predictor of food enhances, whereas a negative predictor of that same food impairs, aversive conditioning. Critically, we also showed that the enhancement produced by the positive predictor is removed by reducing the value of its associated food. In contrast, the impairment triggered by the negative predictor remains insensitive to devaluation of its associated food. These findings provide compelling evidence that the motivational value attributed to a predicted food outcome can directly control appetitive-aversive interactions and, therefore, that motivational processes can modulate emotional processes to generate the final error term on which subsequent learning is based.

2008-01-01

We derive boundary states which describe configurations of multiple parallel branes with arbitrary open string states interactions in bosonic string theory. This is obtained by a careful discussion of the factorization of open/closed string states amplitudes taking care of cycles needed by ensuring vertices commutativity: in particular the discussion reveals that already at the tree level open string knows of the existence of closed string

1991-01-01

The ionization of muonium centers in Si and GaAs have been studied using radio frequency (RF) resonant techniques. In Si all three muonic centers are detectable by RF. No evidence was found for delayed Mu and Mu * states at any temperature. However, our results on the diamagnetic final state (μ f + ) show that it is composed of prompt fractions (as seen by conventional μSR) and delayed fractions arising from the ionization of Mu * and Mu. We observe a full μ f + fraction at 317 K when the Mu relaxation rate is above 10 μs -1 . GaAs differs from the situation in Si in that we observed only a partial conversion of Mu * and Mu to a μ + final state up to 310 K in spite of the fact that the transverse field relaxation rates become very high at 150 and 250 K respectively.

State surveillance of radioactive material transportation. Final report

International Nuclear Information System (INIS)

Salomon, S.N.

1984-02-01

The main objective of this final report on the state surveillance of the transportation of radioactive material (RAM) is to suggest the most cost-effective inspection areas where enforcement actions might be taken by the states during their participation in the State Hazardous Materials Enforcement Development (SHMED) Program. On the basis of the lessons learned from the surveillance program, these actions are enforcement at low-level radioactive burial sites by means of civil penalties and site use suspension; enforcement at airports and at terminals that forward freight; and enforcement of courier companies. More effective and efficient enforcement can be achieved through instrumented police patrol cars and remote surveillance because they require the least amount of time of enforcement personnel. In addition, there is a strong relationship between effective emergency response and enforcement because the appropriate shipping papers, placarding and knowledge of appropriate emergency response procedures lead to improved emergency response. These lessons originate from a ten-state surveillance program from 1977 through 1981 jointly sponsored by the US Nuclear Regulatory Commission (NRC) and DOT. The states give recommendations in the categories of education, training, expanded surveillance, coordination and enforcement. The topics of special interest covered include low-level radioactive waste disposal sites, airports, cargo terminals, highways, ports, and accidents and incidents. The three most common problems in compliance with RAM transportation regulations reported by the states are incorrect package labeling; improper shipping papers; and incorrect or missing placards. Other common problems reported by the states are summarized. The relationship to other studies, the status of the SHMED Program, a synopsis of state RAM surveillance reports, and NRC/DOT expenditures are given

Symmetry-broken states in a system of interacting bosons on a two-leg ladder with a uniform Abelian gauge field

Science.gov (United States)

Greschner, S.; Piraud, M.; Heidrich-Meisner, F.; McCulloch, I. P.; Schollwöck, U.; Vekua, T.

2016-12-01

We study the quantum phases of bosons with repulsive contact interactions on a two-leg ladder in the presence of a uniform Abelian gauge field. The model realizes many interesting states, including Meissner phases, vortex fluids, vortex lattices, charge density waves, and the biased-ladder phase. Our work focuses on the subset of these states that breaks a discrete symmetry. We use density matrix renormalization group simulations to demonstrate the existence of three vortex-lattice states at different vortex densities and we characterize the phase transitions from these phases into neighboring states. Furthermore, we provide an intuitive explanation of the chiral-current reversal effect that is tied to some of these vortex lattices. We also study a charge-density-wave state that exists at 1/4 particle filling at large interaction strengths and flux values close to half a flux quantum. By changing the system parameters, this state can transition into a completely gapped vortex-lattice Mott-insulating state. We elucidate the stability of these phases against nearest-neighbor interactions on the rungs of the ladder relevant for experimental realizations with a synthetic lattice dimension. A charge-density-wave state at 1/3 particle filling can be stabilized for flux values close to half a flux quantum and for very strong on-site interactions in the presence of strong repulsion on the rungs. Finally, we analytically describe the emergence of these phases in the low-density regime, and, in particular, we obtain the boundaries of the biased-ladder phase, i.e., the phase that features a density imbalance between the legs. We make contact with recent quantum-gas experiments that realized related models and discuss signatures of these quantum states in experimentally accessible observables.

The chimera state in colloidal phase oscillators with hydrodynamic interaction

Science.gov (United States)

Hamilton, Evelyn; Bruot, Nicolas; Cicuta, Pietro

2017-12-01

The chimera state is the incongruous situation where coherent and incoherent populations coexist in sets of identical oscillators. Using driven non-linear oscillators interacting purely through hydrodynamic forces at low Reynolds number, previously studied as a simple model of motile cilia supporting waves, we find concurrent incoherent and synchronised subsets in small arrays. The chimeras seen in simulation display a "breathing" aspect, reminiscent of uniformly interacting phase oscillators. In contrast to other systems where chimera has been observed, this system has a well-defined interaction metric, and we know that the emergent dynamics inherit the symmetry of the underlying Oseen tensor eigenmodes. The chimera state can thus be connected to a superposition of eigenstates, whilst considering the mean interaction strength within and across subsystems allows us to make a connection to more generic (and abstract) chimeras in populations of Kuramoto phase oscillators. From this work, we expect the chimera state to emerge in experimental observations of oscillators coupled through hydrodynamic forces.

Dynamics of relaxation to a stationary state for interacting molecular motors

Science.gov (United States)

Gomes, Luiza V. F.; Kolomeisky, Anatoly B.

2018-01-01

Motor proteins are active enzymatic molecules that drive a variety of biological processes, including transfer of genetic information, cellular transport, cell motility and muscle contraction. It is known that these biological molecular motors usually perform their cellular tasks by acting collectively, and there are interactions between individual motors that specify the overall collective behavior. One of the fundamental issues related to the collective dynamics of motor proteins is the question if they function at stationary-state conditions. To investigate this problem, we analyze a relaxation to the stationary state for the system of interacting molecular motors. Our approach utilizes a recently developed theoretical framework, which views the collective dynamics of motor proteins as a totally asymmetric simple exclusion process of interacting particles, where interactions are taken into account via a thermodynamically consistent approach. The dynamics of relaxation to the stationary state is analyzed using a domain-wall method that relies on a mean-field description, which takes into account some correlations. It is found that the system quickly relaxes for repulsive interactions, while attractive interactions always slow down reaching the stationary state. It is also predicted that for some range of parameters the fastest relaxation might be achieved for a weak repulsive interaction. Our theoretical predictions are tested with Monte Carlo computer simulations. The implications of our findings for biological systems are briefly discussed.

During a stateful interaction, a partner service may become unavailable because of a server crash or a temporary network failure. Once the failed service becomes available again, the interaction partners do not have any knowledge about each other’s state, possibly resulting in errors or deadlocks.

Final rubbery state characterization using a hollow cylinder dynamic shear sample on DMA7

Directory of Open Access Journals (Sweden)

Vilaiporn Luksameevanish

2004-09-01

Full Text Available Dynamic properties of raw natural rubber were examined using a hollow cylinder shaped samplesubjected to shear deformation on a laboratory Dynamic Mechanical Analyser. According to Cox-Merz’s study, dynamic complex viscosity obtained by this method showed a good agreement with shear flow viscosity measured by capillary rheometer. A master curve derived from the dynamic properties were then characterized. A crossing point of storage modulus (G’ and loss modulus (G’’ curves in the master curves was used to identify the final rubbery state, which indicated the transition of rubbery state and molten state. The position of this point depends on quantities and types of reinforcing or non-reinforcing fillers. The final rubbery state was shifted to higher frequency or lower temperature. It was found that the final rubbery state of CaCO3-filled rubber compounds was shifted to higher frequency or lower temperature by approximately 4 decades, while the translation of carbon black-filled rubber compounds was lower than unfilled rubber by about 1 decade. This phenomenon can be used to explain rubber elasticity, i.e. a decreasing of die swell of CaCO3 filled compounds at any high processing temperature. On the other hand, high magnitude of die swell for carbon black filled compound was still obtained.

Production of four-prong final states in photon-photon collisions

International Nuclear Information System (INIS)

Buijs, A.

1987-01-01

This thesis describes the measurement, analysis and discussion of the reaction γγ → X, where X is a hadronic final state with four charged particles. In particular, we have investigated the states 2π + 2π - , K ± π -+ π + π - , K + K - π + π - , 2K + 2K - and panti pπ + π - . The experiment was performed with the TPC/Two-Gamma facility at the e + e - collider PEP at the Standford Linear Accelerator Center. The process γγ → 2π + 2π - had been measured in the beginning of this decade. The shape of the measured cross section suggested the presence of a resonance in this channel, and many such interpretations were brought forth in the following years. In ch. 2, these interpretations and theories are reviewed and a motivation is given for the investigation of states similar to 2π + 2π - , but containing kaons and protons. Also, the existing data from related experiments in radiative J/ψ decays and hadronic collisions are listed. In the last section of the chapter, the outstanding features of the TPC/Two-Gamma detector for the measurement of four-prong events are emphasized. Ch. 3 is a very brief overview of the kinematical properties of the two-photon initial state, which is brought about by the exchange of two photons by the colliding electron and positron. In ch. 4 the details of the detector system are given, and the method used to measure and analyze events from exclusive four-particle final states is outlined. The results of the measurements are given in ch. 5. Ch. 6 concludes with a discussion of the results, and an interpretation of the measurements. 89 refs.; 68 figs.; 12 tabs

A model for composite consisting of fermions with internal degrees of freedom interacting via intermediate vector bosons (IVB) is constructed. We find highly localized, low-mass bound states in the Hartree-Fock approximation. We investigate the dependence of these states as function of the coupling constant and vector boson mass. In the limit of infinite vector boson mass the interaction is described by Fermi-type contact forces. (orig.)

Final Report - Composite Fermion Approach to Strongly Interacting Quasi Two Dimensional Electron Gas Systems

Energy Technology Data Exchange (ETDEWEB)

Quinn, John

2009-11-30

Work related to this project introduced the idea of an effective monopole strength Q* that acted as the effective angular momentum of the lowest shell of composite Fermions (CF). This allowed us to predict the angular momentum of the lowest band of energy states for any value of the applied magnetic field simply by determining N{sub QP} the number of quasielectrons (QE) or quasiholes (QH) in a partially filled CF shell and adding angular momenta of the N{sub QP} Fermions excitations. The approach reported treated the filled CF level as a vacuum state which could support QE and QH excitations. Numerical diagonalization of small systems allowed us to determine the angular momenta, the energy, and the pair interaction energies of these elementary excitations. The spectra of low energy states could then be evaluated in a Fermi liquid-like picture, treating the much smaller number of quasiparticles and their interactions instead of the larger system of N electrons with Coulomb interactions.

Microwave modeling of laser plasma interactions. Final report

International Nuclear Information System (INIS)

1983-08-01

For a large laser fusion targets and nanosecond pulse lengths, stimulated Brillouin scattering (SBS) and self-focusing are expected to be significant problems. The goal of the contractual effort was to examine certain aspects of these physical phenomena in a wavelength regime (lambda approx.5 cm) more amenable to detailed diagnostics than that characteristic of laser fusion (lambda approx.1 micron). The effort was to include the design, fabrication and operation of a suitable experimental apparatus. In addition, collaboration with Dr. Neville Luhmann and his associates at UCLA and with Dr. Curt Randall of LLNL, on analysis and modelling of the UCLA experiments was continued. Design and fabrication of the TRW experiment is described under ''Experiment Design'' and ''Experimental Apparatus''. The design goals for the key elements of the experimental apparatus were met, but final integration and operation of the experiment was not accomplished. Some theoretical considerations on the interaction between Stimulated Brillouin Scattering and Self-Focusing are also presented

STATED VS. ENACTED BELIEFS: LOOKING AT PRE-SERVICE TEACHERS' PEDAGOGICAL BELIEFS THROUGH CLASSROOM INTERACTION

Directory of Open Access Journals (Sweden)

Alberto Fajardo

2013-08-01

Full Text Available This article explores the relationship between pedagogical beliefs and classroom practice. Two Colombian pre-service primary school language teachers in the final stage of their five-year training programme were the research participants. Interview and classroom observation were the methods used, and content analysis was the analytical approach. It is argued in this study that by comparing the stated beliefs (as articulated in interviews and enacted beliefs (as manifested in classroom interaction, it is possible to gain a fine-grained understanding of the relationship between beliefs and teaching practice. The findings suggested that while there were significant cases of coherence between beliefs and classroom action, there was also evidence of some incongruent relationships.

Chimera states, which consist of coexisting domains of coherent and incoherent parts, have been observed in a variety of systems. Most of previous works on chimera states have taken into account specific form of interaction between oscillators, for example, sinusoidal coupling or diffusive coupling. Here, we investigate chimera dynamics in nonlocally coupled phase oscillators with biharmonic interaction. We find novel chimera states with features such as that oscillators in the same coherent cluster may split into two groups with a phase difference around π/2 and that oscillators in adjacent coherent clusters may have a phase difference close to π/2. The different impacts of the coupling ranges in the first and the second harmonic interactions on chimera dynamics are investigated based on the synchronous dynamics in globally coupled phase oscillators. Our study suggests a new direction in the field of chimera dynamics.

Double ionization of He and Li by ion impact: Final state correlation

The total cross-sections for atomic double ionization are evaluated with a two-step approximation, by considering that the projectile ionizes successively each electron. Single ionization probabilities are calculated within the continuum distorted-wave with eikonal initial state (CDW-EIS) formalism. The initial and final atomic wave functions are obtained by solving numerically the atomic wave equations with an optimized potential model (OPM). The electron-electron correlation in the final state is investigated following three different approaches: the usual Gamow factor, a modified Gamow factor with an effective charge and a mean value of the electron-electron repulsive Coulomb wave. The calculations are compared with experimental data and good agreement is found for double ionization of He and Li atoms by H{sup +}, He{sup 2+}and Li{sup 3+} impact, at intermediate energies.

Сharmonium production using decays to hadronic final states at LHCb

CERN Multimedia

Usachov, Andrii

2018-01-01

Non Relativistic QCD (NRQCD) provides so far the most successful framework to describe the production of the $J^{PC}=1^{--}$ quarkonium states. However, a comprehensive description of the production and polarisation of the $J/\\psi$ state at Tevatron and LHC in the complete $p_T$ and rapidity range remains a challenge. The heavy quark spin symmetry yields direct links between the long distance matrix elements describing hadroproduction of different charmonium states. The production of linked charmonium states - $\\eta_c$ and $J/\\psi$, $\\eta_c(2S)$ and $\\psi(2S)$, and the three $\\chi_c$ states - can thus be described simultaneously. Experimentally the production of non-$1^{--}$ charmonium states can be studied by reconstructing their decays to fully hadronic final states. The LHCb measurement of the $\\eta_c(1S)$ prompt production and production in inclusive b-hadron decays via the decay $\\eta_c(1S)\\to p\\bar{p}$ is discussed together with its strong impact on NRQCD-based theory models. Recent LHCb measurement of ...

Game Theoretic Interaction and Decision: A Quantum Analysis

Directory of Open Access Journals (Sweden)

Ulrich Faigle

2017-11-01

Full Text Available An interaction system has a finite set of agents that interact pairwise, depending on the current state of the system. Symmetric decomposition of the matrix of interaction coefficients yields the representation of states by self-adjoint matrices and hence a spectral representation. As a result, cooperation systems, decision systems and quantum systems all become visible as manifestations of special interaction systems. The treatment of the theory is purely mathematical and does not require any special knowledge of physics. It is shown how standard notions in cooperative game theory arise naturally in this context. In particular, states of general interaction systems are seen to arise as linear superpositions of pure quantum states and Fourier transformation to become meaningful. Moreover, quantum games fall into this framework. Finally, a theory of Markov evolution of interaction states is presented that generalizes classical homogeneous Markov chains to the present context.

The Melt Vessel Interaction (MVI) project is concerned with the consequences of the interactions that a core melt, generated during a postulated severe accident in a light water reactor, may have with the pressure vessel. In particular, the issues concerned with the failure of the vessel bottom head are the focus of the research. The specific objectives of the project are to obtain data and develop validated models, which could be applied to prototypic plants, and accident conditions, for resolution of issues related to the melt vessel interactions. The project work has been performed by nine partners having varied responsibility. The work included a large number of experiments, with simulant materials, whose observations and results are employed, respectively, to understand the physical mechanisms and to develop validated models. Applications to the prototypic geometry and conditions have also been performed. This report is volume 1 of the Final Report for the Project, in which a summary of the progress achieved in the experimental program is provided. We have, however, included some aspects of the modeling activities. Volume 2 of the Final report describes the progress achieved in the modeling program. The progress achieved in the experimental and modeling parts of the Project has led to the resolution of some of the issues of melt vessel interaction. Considerable progress was also achieved towards resolution of the remaining issues.

Nevada State plan; final approval determination. Occupational Safety and Health Administration (OSHA), U.S. Department of Labor. Final State plan approval--Nevada.

Science.gov (United States)

2000-04-18

This document amends OSHA's regulations to reflect the Assistant Secretary's decision granting final approval to the Nevada State plan. As a result of this affirmative determination under section 18(e) of the Occupational Safety and Health Act of 1970, Federal OSHA's standards and enforcement authority no longer apply to occupational safety and health issues covered by the Nevada plan, and authority for Federal concurrent jurisdiction is relinquished. Federal enforcement jurisdiction is retained over any private sector maritime employment, private sector employers on Indian land, and any contractors or subcontractors on any Federal establishment where the land is exclusive Federal jurisdiction. Federal jurisdiction remains in effect with respect to Federal government employers and employees. Federal OSHA will also retain authority for coverage of the United States Postal Service (USPS), including USPS employees, contract employees, and contractor-operated facilities engaged in USPS mail operations.

On the relevance of the final ionic state to the (e,2e) TDCS

International Nuclear Information System (INIS)

Stefani, G.

1990-01-01

The He II n=2 satellite in the He ionisation spectrum is investigated by measuring the angular dependence of the (e, 2e) triple differential cross section (TDCS) in asymmetric geometry for the first time, at moderate momentum transfer (0.8 a 0 -1 ) and low ejected electron energy (20 eV). The generalised oscillator strengths for the transitions to the n=1 and n=2 He II states are derived from the TDCS and their ratio is in fair agreement with a recent close coupling calculation. The experimental angular distribution of the n=2 TDCS shows peculiarities, typical of continuum final-state correlations, which appear to be much more relevant when the final ionic state is the excited one.

We present a study of top quark polarization in $t \\overline{t}$ events produced in $p \\overline{p}$ collisions at $\\sqrt{s}=1.96$ TeV. Data correspond to 9.7 fb$^{-1}$ collected with the D0 detector at the Tevatron. We use final states containing a lepton and at least three jets. The polarization is measured using the distribution of leptons along the beam and helicity axes, and the axis normal to the production plane. This is the first measurement of top quark polarization at the Tevatron in $\\ell$+jets final states, and first measurement of transverse polarization in $t \\overline{t}$ production. The observed distributions are consistent with the standard model.

We compute time-ordered 2- and 3-pt correlation functions of CFT scalar operators between generic in/out states. The calculation is holographically carried out by considering a non backreacting AdS scalar field with a λϕ{sup 3} self-interaction term on a combination of Euclidean and Lorentzian AdS sections following the Skenderis-van Rees prescription. We show that, although working in an essentially different set up, the final result for the 3-pt correlators agree with those of Rastelli et al. for Euclidean AdS. By analyzing the inner product between the in/out excited states in the large N approximation, we argue that a cubic bulk interaction deforms the excited states from coherent into squeezed. Finally, a diagrammatic interpretation of the results suggests some general properties for the n-point correlation functions between excited states.

Fine structure resolved 4p photoemission studies have been performed on free rubidium atoms in the ground state and after excitation into the [Kr]5p 2 P 1/2 and 2 P 3/2 states. The 4p 5 5p final states have been excited in the 4p 6 5s→4p 5 5p conjugate shakeup process from ground state atoms as well as by direct photoemission from laser excited atoms. The relative intensities differ considerably in these three excitation schemes. The differences in the laser excited spectra could be described well using calculations based on the pure jK-coupling scheme. Thereby it was possible to specify the character of the various final states. Furthermore it has been possible to resolve two of the final states whose energy separation is smaller than the experimental resolution by selectively exciting them in a two step scheme, where the laser selects the spin-orbit coupling in the intermediate state and determines the final state coupling after x-ray photoemission

In order to get maximum information on the hadronic final states and sum rules in deep inelastic processes, Regge phenomenology and quarks parton model have been used. The unified picture for the production of hadrons of type i as a function of Bjorken and Feyman variables with only one adjustable parameter is formulated. The results of neutrino experiments and the production of charm particles are discussed in sum rules. (author)

We report the results of a search for R parity violating (RPV) interactions leading to the production of supersymmetric sneutrinos decaying into eμ final states using 5.3 fb-1 of integrated luminosity collected by the D0 experiment at the Fermilab Tevatron Collider. Having observed no evidence for production of eμ resonances, we set direct bounds on the RPV couplings λ311' and λ312 as a function of sneutrino mass.

Understanding the mechanism of DNA-cisplatin interaction is essential for clinical application and novel drug design. As an emerging single-molecule technology, solid-state nanopore has been employed in biomolecule detection and probing DNA-molecule interactions. Herein, we reported a real-time monitoring of DNA-cisplatin interaction by employing solid-state SiN nanopores. The DNA-cisplatin interacting process is clearly classified into three stages by measuring the capture rate of DNA-cisplatin adducts. In the first stage, the negative charged DNA molecules were partially discharged due to the bonding of positive charged cisplatin and forming of mono-adducts. In the second stage, forming of DNA-cisplatin di-adducts with the adjacent bases results in DNA bending and softening. The capture rate increases since the softened bi-adducts experience a lower barrier to thread into the nanopores. In the third stage, complex structures, such as micro-loop, are formed and the DNA-cisplatin adducts are aggregated. The capture rate decreases to zero as the aggregated adduct grows to the size of the pore. The characteristic time of this stage was found to be linear with the diameter of the nanopore and this dynamic process can be described with a second-order reaction model. We are grateful to Laboratory of Microfabrication, Dr. Y. Yao, and Prof. R.C. Yu (Institute of Physics, Chinese Academy of Sciences) for technical assistance.

Romeo, Francesco

2017-01-01

The most recent results on searches in lepton plus jet final states motivated bydifferent models beyond the standard model are presented, using pp collision datacollected by the ATLAS and CMS detectors during Run I and Run II at theCERN LHC. Leptoquarks and heavy Majorana neutrinos that arise in theleft-right model are looked for in the final states with two leptons and two jets( ll + jj, l = e, mu, tau ). Heavy Majorana neutrinos are further investigated byrelying on a composite-fermion scenario, considering two leptons and onelarge-radius jet ( ll + J, l = e, mu), and in the context of a model with Type-1seesaw mechanism, requiring two same-sign leptons plus dijet( ll + jj, l,l = e, mu). Finally, models of microscopic black holes with two to sixextra dimensions are tested by analysing the channels with at least one leptonand two additional jets ( l + jj, l = e, mu). In all the searches, the observed dataare in good agreement with the standard model prediction and 95pct confidencelevel upper limits are set o...

Study of B Meson Decays to ppbarh Final States

Energy Technology Data Exchange (ETDEWEB)

Hryn' ova, Tetiana B.; /SLAC

2006-03-22

B mesons are unique among well-established non-quarkonium mesons in their ability to decay into baryons. Baryonic B decays offer a wide range of interesting areas of study: they can be used to test our theoretical understanding of rare decay processes involving baryons, search for direct CP violation and study low-energy QCD. This thesis presents measurements of branching fractions and a study of the decay dynamics of the charmless three-body decays of B meson into p{bar p}h final states, where h = {pi}{sup +}, K{sup +}, K{sub S}{sup 0}, K*{sup 0} or K*{sup +}. With a sample of 232 million {Upsilon}(4S) {yields} B{bar B} events collected with the BaBar detector, we report the first observation of the B {yields} p{bar p}K*{sup 0} decay, and provide improved measurements of branching fractions of the other modes. The distribution of the three final-state particles is of particular interest since it provides dynamical information on the possible presence of exotic intermediate states such as the hypothetical pentaquark states {Theta}*{sup ++} and {Theta}{sup +}in the m{sub pK{sup +}} and m{sub pK{sub S}{sup 0}} spectra, respectively, or glueball states (such as the tensor glueball f{sub J}(2220)) in the m{sub p{bar p}} spectrum. No evidence for exotic states is found and upper limits on the branching fractions are set. An enhancement at low p{bar p} mass is observed in all the B {yields} p{bar p}h modes, and its shape is compared between the decay modes and with the shape of the time-like proton form factor. A Dalitz plot asymmetry in B {yields} p{bar p}K{sup +} mode suggests dominance of the penguin amplitude in this decay and disfavors the possibility that the low mass p{bar p} enhancement originates from the presence of a resonance below threshold (such as the recently seen baryonium candidate at 1835 MeV/c{sup 2}). We also identify decays of the type B {yields} X{sub c{bar c}}h {yields} p{bar p}h, where h = K{sup +}, K{sub S}{sup 0}, K*{sup 0} or K*{sup +}, and X

Searches for diboson production at the Tevatron in final states containing heavy-flavor jets

Directory of Open Access Journals (Sweden)

2012-06-01

Full Text Available Recent searches performed by the CDF and D0 collaborations at the Tevatron for diboson production in final states containing heavy-flavor jets are reported. The searches for WZ and ZZ can be regarded as the ultimate benchmark for the corresponding searches for a low-mass Higgs boson in the WH and ZH final states. Using the exact same techniques as for those Higgs boson searches, the D0 collaboration measured a cross section for WZ/ZZ production of 1.13 ± 0.36 times its expectation in the standard model, with a diboson signal significance of 3.3 standard deviations (2.9 expected.

Italian Physical Society b-hadron semileptonic decays with $\\tau$ leptons in final states in LHCb

CERN Document Server

2017-01-01

Lepton universality, described in the Standard Model, predicts equal coupling between gauge bosons and the three lepton families. SM extensions give additional interactions, implying in some cases a stronger coupling with the third generation of leptons. Semileptonic decays of b-hadrons provide a sensitive probe to such New Physics effects. The presence of additional charged Higgs bosons, required by such SM extensions, can have significant effect on the semileptonic decay rate of $\\bar{B}^0 \\to D^{*+}τ^−\\bar{ν}_{τ}$ . The combination of experimental measurements give a deviation from the standard model prediction of about 4 σ. It is therefore important to perform additional measurements in this sector in order to improve the precision and confirm or disprove this deviation. Results obtained by LHCb on $B^0 \\to D^{*−}τ^+ ν_τ$ decays, where the τ decays leptonically, are reported. The LHCb perspectives with other final states are discussed.

We report measurements of single-particle inclusive spectra and two-particle azimuthal distributions of charged hadrons at high transverse momentum (high p(T)) in minimum bias and central d+Au collisions at sqrt[s(NN)]=200 GeV. The inclusive yield is enhanced in d+Au collisions relative to binary-scaled p+p collisions, while the two-particle azimuthal distributions are very similar to those observed in p+p collisions. These results demonstrate that the strong suppression of the inclusive yield and back-to-back correlations at high p(T) previously observed in central Au+Au collisions are due to final-state interactions with the dense medium generated in such collisions.

On the theory of direct reactions with many particle final states

International Nuclear Information System (INIS)

Trautmann, D.; Baur, G.

1977-01-01

We study the theory of direct reactions with many particle final states. First, we concentrate on the DWBA formulation of the break-up of deuterons on heavy nuclei below the Coulomb barrier. Because there are no free parameters, this permits a clean test of the theory by comparing it to the experimental data. The agreement is very good. The theory is applied to the break-up of antideuteronic atoms. Then the effect of virtual deuteron break-up on Rutherford scattering is studied. It is small, but it seems to be measurable. Also the deuteron break-up above the Coulomb barrier can be well explained theoretically. In this context, small effects are studied briefly. A semiclassical theory of the break-up process is given, which results in an intuitive picture and a fast computational method. Our theory lends itself in a natural way to the study of stripping reactions to unbound states. The relation of stripping into the continuum to elastic scattering of the transferred particle on the same target nucleus is explained. Then the connection of stripping to bound and unbound states is established. Finally various examples of stripping of uncharged and charged particles into the continuum are given to illustrate the theory. Resonance wave functions describing the transferred particle are discussed. In a conclusion an outlook for possible future developments of experiment and theory is given. (author)

Search for the sixth quark in hadronic final states of the electron-positron annihilation at PETRA

Rykaczewski, H.

1981-08-01

Using the MARK-J detector at the PETRA storage ring hadronic final states of the electron-positron annihilation were studied. One aim of these measurements is mainly the search for a further quark, the top quark. The results yield no indications for bound state of the top quark in the energy range between 29.90 and 37.72 GeV. From the analysis of the spatial energy distribution of hadronic final states as well the rate of inclusive muon events also the result is obtained that top quarks are not produced below an energy of W=36.72 GeV.

This report describes the way EU Member States have transposed the sustainability and chain of custody requirements for biofuels as laid down in the Renewable Energy Directive (RED) and Fuel Quality Directive (FQD). In the assessment of Member States' implementation, the report mainly focuses on effectiveness and administrative burden. Have Member States transposed the Directives in such a way that compliance with the sustainability criteria can be ensured as effectively as possible? To what extent does the Member States' implementation lead to unnecessary administrative burden for economic operators in the (bio)fuel supply chain? The report focuses specifically on the transposition of the sustainability and chain of custody requirements, not on the target for renewables on transport. This means that for example the double counting provision is not included as part of the scope of this report. This report starts with an introduction covering the implementation of the Renewable Energy (and Fuel Quality) Directive into national legislation, the methodology by which Member States were assessed against effectiveness and administrative burden and the categorisation of Member State's national systems for RED-implementation (Chapter 1). The report continues with a high level description of each Member State system assessed (Chapter 2). Following this, the report includes analysis of the Member States on the effectiveness and administrative burden of a number of key ('major') measures (Chapter 3). The final chapter presents the conclusions and recommendations (Chapter 4)

Exchange interaction in scattering on the bound state

In the framework of the one-time formulation of three-body problem in quantum field theory, the problem of scattering on the bound state is considered for the case when one of the incident particles is identical to one of the particles of the target. It is shown that due to the identical nature of these particles the exchange interaction takes place which can be connected with the mechanism of scattering on the bound state with the rearrangement

We report on the investigation of the final state in interactions of quasi-real photons with protons. The data were taken with the H1 detector at the HERA ep collider. Evidence for hard interactions is seen in both single particle spectra and jet formation. The data can best be described by inclusion of resolved photon processes as predicted by QCD. (orig.)

Measurement of Reconstructed Charged Particle Multiplicities of Neutrino Interactions in MicroBooNE

Energy Technology Data Exchange (ETDEWEB)

Rafique, Aleena [Kansas State Univ., Manhattan, KS (United States)

2017-09-25

Here, we compare the observed charged particle multiplicity distributions in the MicroBooNE liquid argon time projection chamber from neutrino interactions in a restricted final state phase space to predictions of this distribution from several GENIE models. The measurement uses a data sample consisting of neutrino interactions with a final state muon candidate fully contained within the MicroBooNE detector. These data were collected in 2015-2016 with the Fermilab Booster Neutrino Beam (BNB), which has an average neutrino energy of 800 MeV, using an exposure corresponding to 5e19 protons-on-target. The analysis employs fully automatic event selection and charged particle track reconstruction and uses a data-driven technique to determine the contribution to each multiplicity bin from neutrino interactions and cosmic-induced backgrounds. The restricted phase space employed makes the measurement most sensitive to the higher-energy charged particles expected from primary neutrino-argon collisions and less sensitive to lower energy protons expected to be produced in final state interactions of collision products with the target argon nucleus.

State-Level Workshops on Ethanol for Transportation: Final Report

Energy Technology Data Exchange (ETDEWEB)

Graf, A.

2004-01-01

Final report on subcontract for holding four state-level workshops (Hawaii, Kentucky, Nevada, California) to facilitate development of ethanol production facilities in those states. In 2002/2003, under contract to the National Renewable Energy Laboratory, BBI International conducted state-level workshops ethanol in Hawaii, Nevada, Kentucky and California. These four workshops followed over 30 other workshops previous held under the Ethanol Workshop Series program sponsored by the U.S. Department of Energy. Two other workshops were conducted by BBI International during 2003, Oklahoma and Kansas, under contract to the Western Regional Biomass Energy Program. The Ethanol Workshop Series (EWS) was intended to provide a forum for interest groups to gather and discuss what needs to be accomplished to facilitate ethanol production in-state using local biomass resources. In addition, the EWS was to provide a promotional and educational forum for policy makers, community leaders, media and potential stakeholders. It was recognized that to eventually achieve biomass-ethanol production, it was necessary to support grain-ethanol production as a bridge. The long-term goal of the Workshops was to facilitate the development of biomass ethanol plants at a state-level. The near-term goal was to provide correct and positive information for education, promotion, production and use of fuel ethanol. The EWS drew from 65 to over 200 attendees and were deemed by the local organizers to have served the objectives set out by the U.S. Department of Energy.

Unparticle self-interactions at the Large Hadron Collider

International Nuclear Information System (INIS)

Bergstroem, Johannes; Ohlsson, Tommy

2009-01-01

We investigate the effect of unparticle self-interactions at the Large Hadron Collider (LHC). Especially, we discuss the three-point correlation function, which is determined by conformal symmetry up to a constant, and study its relation to processes with four-particle final states. These processes could be used as a favorable way to look for unparticle physics, and for weak enough couplings to the standard model, even the only way. We find updated upper bounds on the cross sections for unparticle-mediated 4γ final states at the LHC and novel upper bounds for the corresponding 2γ2l and 4l final states. The size of the allowed cross sections obtained are comparably large for large values of the scaling dimension of the unparticle sector, but they decrease with decreasing values of this parameter. In addition, we present relevant distributions for the different final states, enabling the possible identification of the unparticle scaling dimension if there was to be a large number of events of such final states at the LHC.

Final-state effects on superfluid 4He in the deep inelastic regime

Mazzanti, F.; Boronat, J.; Polls, A.

1996-01-01

A study of final-state effects (FSE) on the dynamic structure function of superfluid 4 He in the Gersch-Rodriguez formalism is presented. The main ingredients needed in the calculation are the momentum distribution and the semidiagonal two-body density matrix. The influence of these ground-state quantities on the FSE is analyzed. A variational form of ρ 2 is used, even though simpler forms turn out to give accurate results if properly chosen. Comparison to the experimental response at high momentum transfer is performed. The predicted response is quite sensitive to slight variations on the value of the condensate fraction, the best agreement with experiment being obtained with n 0 =0.082. Sum rules of the FSE broadening function are also derived and commented. Finally, it is shown that Gersch-Rodriguez theory produces results as accurate as those coming from other more recent FSE theories. copyright 1996 The American Physical Society

The reaction p(@3.5 GeV)+p→p+Λ+K{sup +} can be studied to search for the existence of kaonic bound states like ppK{sup −} leading to this final state. This effort has been motivated by the assumption that in p+p collisions the Λ(1405) resonance can act as a doorway to the formation of the kaonic bound states. The status of this analysis within the HADES Collaboration, with particular emphasis on the comparison to simulations, is shown in this work and the deviation method utilized by the DISTO Collaboration in a similar analysis is discussed. The outcome suggests the employment of a partial wave analysis do disentangle the different contributions to the measured pK{sup +}Λ final state.

Anisotropic surface-state-mediated RKKY interaction between adatoms on a hexagonal lattice

Science.gov (United States)

Patrone, Paul N.; Einstein, T. L.

2012-01-01

Motivated by recent numerical studies of Ag on Pt(111), we derive an expression for the RKKY interaction mediated by surface states, considering the effect of anisotropy in the Fermi edge. Our analysis is based on a stationary phase approximation. The main contribution to the interaction comes from electrons whose Fermi velocity vF is parallel to the vector R connecting the interacting adatoms; we show that, in general, the corresponding Fermi wave vector kF is not parallel to R. The interaction is oscillatory; the amplitude and wavelength of oscillations have angular dependence arising from the anisotropy of the surface-state band structure. The wavelength, in particular, is determined by the projection of this kF (corresponding to vF) onto the direction of R. Our analysis is easily generalized to other systems. For Ag on Pt(111), our results indicate that the RKKY interaction between pairs of adatoms should be nearly isotropic and so cannot account for the anisotropy found in the studies motivating our work. However, for metals with surface-state dispersions similar to Be(101¯0), we show that the RKKY interaction should have considerable anisotropy.

Measurement of top quark polarization in top-antitop lepton+jets final states at DØ

Energy Technology Data Exchange (ETDEWEB)

Augsten, Kamil [Czech Technical Univ., Prague (Czech Republic)

2017-01-01

This thesis presents a measurement of the top quark polarization in the $t\\overline{t}$ events produced in $p\\overline{p}$ collisions at $\\sqrt{s}=1.96$ TeV using data corresponding to 9.7 fb$^{-1}$ of integrated luminosity collected with the D0 detector at the Fermilab Tevatron Collider. The final states used in the measurement contain one lepton and at least three jets. The polarization is measured using the angular distribution of leptons along three different axes: the beam axis, the helicity axis, and the transverse axis normal to the $t\\overline{t}$ production plane. This is the first measurement of top quark polarization at the Tevatron Collider in lepton+jets final states, and the first measurement of transverse polarization in $t\\overline{t}$ production. The polarization along the beam axis is combined with the previous result in the dilepton final states by the D0 experiment. The observed distributions are consistent with the Standard Model of nearly no polarization and no indication for beyond Standard Model physics is observed. The measurement offers legacy result from unique Tevatron Collider data and provides more information about the top quark production and decays, about the properties of the heaviest elementary particle.

Final state dipole showers and the DGLAP equation

International Nuclear Information System (INIS)

Nagy, Zoltan; Soper, Davison E.

2009-01-01

We study a parton shower description, based on a dipole picture, of the final state in electron-positron annihilation. In such a shower, the distribution function describing the inclusive probability to find a quark with a given energy depends on the shower evolution time. Starting from the exclusive evolution equation for the shower, we derive an equation for the evolution of the inclusive quark energy distribution in the limit of strong ordering in shower evolution time of the successive parton splittings. We find that, as expected, this is the DGLAP equation. This paper is a response to a recent paper of Dokshitzer and Marchesini that raised troubling issues about whether a dipole based shower could give the DGLAP equation for the quark energy distribution.

Unusual initial and final state effects in quantum chromodynamics

International Nuclear Information System (INIS)

Nelson, C.A.

1990-12-01

We have constructed fundamental test which can be used to probe discrete symmetries, and their possible violations, in the required ''new physics'' beyond the standard model. In a recent paper for applications at an e + e - collider, we have proposed a simple test for ''maximal P -- maximal C'' violation in the Z degree → τ 1 - τ 1 + coupling. For τ minus-plus → π minus-plus ν, for example, this test is based on an azimuthal correlation function I(φ e , φ) where the azimuthal angles are defined relative to the final π 1 - . For e - e + collisions in the Γ or J/Ψ regions, I(φ e , φ) can be used to test for a complex phase in the γ* → τ - τ + coupling. In other research programs, we are continuing to investigate our proposal that partons be identified with nearly degenerate, coherent quark-gluon ''jet'' states, and have proven a completeness relation for the q-analogue of the unusual coherent states

Initial state fluctuations and final state correlations in relativistic heavy-ion collisions

International Nuclear Information System (INIS)

Luzum, Matthew; Petersen, Hannah

2014-01-01

We review the phenomenology and theory of bulk observables in ultra-relativistic heavy-ion collisions, focusing on recent developments involving event-by-event fluctuations in the initial stages of a heavy-ion collision, and how they manifest in observed correlations. We first define the relevant observables and show how each measurement is related to underlying theoretical quantities. Then we review the prevailing picture of the various stages of a collision, including the state-of-the-art modeling of the initial stages of a collision and subsequent hydrodynamic evolution, as well as hadronic scattering and freeze-out in the later stages. We then discuss the recent results that have shaped our current understanding and identify the challenges that remain. Finally, we point out open issues and the potential for progress in the field.

Experimentally measuring a quantum state by the Heisenberg exchange interaction in a single apparatus

International Nuclear Information System (INIS)

Peng Xinhua; Du Jiangfeng; Suter, D.

2005-01-01

Full text: Quantum information processing requires the effective measurement of quantum states. An important method, called quantum state tomography, needs measuring a complete set of observables on the measured system to determine its unknown quantum state ρ. The measurement involves certain noncommuting observables as a result of Bohr's complementarity. Very recently, Allahverdyan et al. proposed a new method in which the unknown quantum state r is determined by measuring a set of commuting observables in the price of a controlled interaction with an auxiliary system. If both systems S and A are spins, their z components (σ z ) can be chosen to measure after some specific Heisenberg exchange interaction. We study in detail a general Heisenberg XYZ model for a two-qubit system and present two classes of special Heisenberg interactions which can serve as the controlled interaction in Allahverdyan's scheme when the state of the auxiliary system A is initially completely disordered. Using the nuclear magnetic resonance techniques, the measurement scheme in a single apparatus has been experimentally demonstrated by designing the quantum circuit to simulate the Heisenberg exchange interaction.

Mikhail, I. F. I.; Ismail, I. M. M.; Ameen, M.

2018-02-01

The squeezed states of dressed magnons in ferromagnets have been investigated. No effective Debye cutoff frequency has been assumed unlike what has been done hitherto. Instead, the results have been expressed throughout in terms of the reduced temperature. The effect of dressed magnon-phonon interactions on the formulation of these states has been studied. It has been shown that the magnon-phonon interactions play a significant role in determining the squeeze factor and the variation of the dressed magnon effective mass with temperature.

Z' to tau tau - emu final state

CERN Document Server

CMS Collaboration

2015-01-01

A search for new physics beyond the standard model in the high-mass ditau final state with one tau decaying in the electron channel and one tau decaying in the muon channel is performed using proton-proton collisions at $\\sqrt{s}$ = 8 TeV recorded by the CMS experiment at the LHC. The data correspond to an integrated luminosity of 19.7 fb$^{-1}$. The data are in good agreement with the standard model prediction. An upper limit at 95$\\%$ CL on the product of cross section times branching fraction into tau pairs is calculated as a function of the resonance mass for the Sequential Standard Model $Z'$ ($Z'_{SSM}$ masses excluded up to 1300 GeV) and for the GUT-inspired $E_6$ model ($Z'_{\\psi}$ masses excluded up to 810 GeV). The results are further interpreted in terms of the Arkani-Hamed, Dimopolous, and Dvali (ADD) model, setting an exclusion limit on the parameter $\\Lambda_T$ up to 2800 GeV.

A study of $D^+\\pi^-$, $D^0 \\pi^+$ and $D^{*+}\\pi^-$ final states is performed using pp collision data, corresponding to an integrated luminosity of 1.0 $fb^{-1}$, collected at a centre-of-mass energy of 7 TeV with the LHCb detector. The $D_1(2420)^0$ resonance is observed in the $D^{*+}\\pi^-$ final state and the $D^*_2(2460)$ resonance is observed in the $D^+\\pi^-$, $D^0 \\pi^+$ and $D^{*+}\\pi^-$ final states. For both resonances, their properties and spin-parity assignments are obtained. In addition, two natural parity and two unnatural parity resonances are observed in the mass region between 2500 and 2800 MeV. Further structures in the region around 3000 MeV are observed in all the $D^{*+}\\pi^-$, $D^+\\pi^-$ and $D^0 \\pi^+$ final states.

Relaxation and final-state structure in XPS of atoms, molecules, and metals

Shirley, D.A.; Martin, R.L.; McFeely, F.R.; Kowalczyk, S.P.; Ley, L.

1975-03-01

Photoemission from a many-electron system is a many-electron process, even though the transition operator may affect only one electron directly. Relaxation and ''shake-up'' structure are related by a sum rule. When one is present, the other must be also. Shake-up structure is shown to be accurately predictable in atomic neon and molecular HF if the CI calculations are done carefully. In metals the sum rule also applies but final-state effects usually appear as relaxation energy, which is large even for valence electrons. Finally, in rare-earth metals discrete shake-up structure is observable in the 4p region. (7 figs, 30 refs) (auth)

The aim of the analysis was the measurement of the ratios R(ν) and R(antiν) of neutral-current to charged-current cross sections. The background due to neutron interactions was computed. A lower and an upper limit of the background was obtained. Bounds on the ratios R(ν) and R(antiν) are given using these limits: 0.11 [fr

Chiral helimagnetic state in a Kondo lattice model with the Dzyaloshinskii-Moriya interaction

Monoaxial chiral magnets can form a noncollinear twisted spin structure called the chiral helimagnetic state. We study magnetic properties of such a chiral helimagnetic state, with emphasis on the effect of itinerant electrons. Modeling a monoaxial chiral helimagnet by a one-dimensional Kondo lattice model with the Dzyaloshinskii-Moriya interaction, we perform a variational calculation to elucidate the stable spin configuration in the ground state. We obtain a chiral helimagnetic state as a candidate for the ground state, whose helical pitch is modulated by the model parameters: the Kondo coupling, the Dzyaloshinski-Moriya interaction, and electron filling.

Search for high mass resonances in dielectron final state

CERN Document Server

CMS Collaboration

2018-01-01

A search for high mass resonances in the dielectron final state is performed using proton-proton collision data at a center-of-mass energy of $13~\\mathrm{TeV}$ collected by the CMS experiment at the LHC in 2017. The integrated luminosity corresponds to $41~\\mathrm{fb}^{-1}$. No evidence for a significant deviation from standard model expectation is observed. The sensitivity of the search is increased by combining these data with a previously analysed set of data obtained in 2016 and corresponding to a luminosity of $36~\\mathrm{fb}^{-1}$. Upper bounds are set on the masses of hypothetical particles that arise in new-physics scenarios.

Central Production of Two-Pseudoscalar Final States at COMPASS

2013-01-01

COMPASS is a fixed-target experiment at CERN SPS which focused on light-quark meson spectroscopy during the data-taking periods in 2008 and 2009. The central exclusive production of glueball candidates is studied with a 190GeV/c proton beam impinging on a liquid hydrogen target. We select centrally produced systems with two pseudo-scalar mesons in the final state. The decay of this system is decomposed in terms of partial waves, with particular attention paid to the inherent mathematical ambiguities of the amplitude analysis. We show that simple parametrisation are able to describe the mass dependence of the fit results with sensible Breit-Wigner parameters.

Radiative decays of the psi(3097) to two meson final states

International Nuclear Information System (INIS)

Einsweiler, K.F.

1984-05-01

The MARK III detector operating at the SPEAR storage ring has acquired a sample of 2.7 x 10 6 produced psi(3097)'s. These events are used to investigate the radiative decays of the psi to two meson final states. Such decays are of topical interest because of the unusual QCD laboratory they provide - of particular interest is the possibility of observing glueball states. The process psi → γπ + π - is studied. The f(1270) tensor meson is observed and the helicity structure of its production is measured. The data indicate that helicity 2 is suppressed, in disagreement with lowest order QCD calculations. Evidence is presented for the first observation of the theta(1700) in the π + π - final state. The strong, but not complete, suppression of this state in the ππ channel, combined with the absence of a J/sup P/ = 2 + signal in a recent MARK III analysis of psi → γ rho rho, suggest a very mysterious nature for the theta(1700). The process psi → γK + K - is also studied. The f'(1515) tensor meson is observed with a branching ratio in agreement with the SU(3) symmetry prediction for the standard two gluon radiative decay diagram with no mixing corrections. The helicity structure of the f'(1515) is measured for the first time, and is found to be similar to that of the f(1270). The theta(1700) is observed with high statistics. Its spin and parity are measured, with the result that J/sup P/ = 2 + is preferred over J/sup P/ = 0 + at the 99.9% C.L. In addition, evidence is presented for a remarkable narrow state, designated the xi(2220). Its parameters are measured to be: m = 2.218 +- 0.003 +- 0.010 GeV, GAMMA less than or equal to 0.040 GeV at 95% C.L., and BR(psi → γxi(2220))BR(xi(2220) → K + K - ) = (5.7 +- 1.9 +- 1.4) x 10 -5

Background: Double-β decay is a rare nuclear process in which two neutrons in the nucleus are converted to two protons with the emission of two electrons and two electron antineutrinos. Purpose: We measured the half-life of the two-neutrino double-β decay of 150Nd to excited final states of 150Sm by detecting the deexcitation γ rays of the daughter nucleus. Method: This study yields the first detection of the coincidence γ rays from the 0 1+ excited state of 150Sm. These γ rays have energies of 333.97 and 406.52 keV and are emitted in coincidence through a 01+→21+→0gs+ transition. Results: The enriched Nd2O3 sample consisted of 40.13 g 150Nd and was observed for 642.8 days at the Kimballton Underground Research Facility, producing 21.6 net events in the region of interest. This count rate gives a half-life of T1 /2=[1 .07-0.25+0.45(stat ) ±0.07 (syst ) ] ×1020 yr. The effective nuclear matrix element was found to be 0.0465 -0.0054+0.0098. Finally, lower limits were obtained for decays to higher excited final states. Conclusions: Our half-life measurement agrees within uncertainties with another recent measurement in which no coincidence was employed. Our nuclear matrix element calculation may have an impact on a recent neutrinoless double-β decay nuclear matrix element calculation which implies that the decay to the first excited state in 150Sm is favored over that to the ground state.

Search of New Physics with Boosted Higgs Boson in Hadronic Final States with ATLAS Detector

CERN Document Server

AUTHOR|(INSPIRE)INSPIRE-00387563

The discovery of a Higgs boson at the Large Hadron Collider (LHC) confirms the validity of the Standard Model (SM) in the description of particle interactions at electroweak scale. However, radioactive corrections to the Higgs mass drives its value to the model's validity limit, indicating either extreme fine-tuning or the presence of new physics at higher energy scale. Since 2015, the LHC starts its Run 2 journey with unprecedented center of mass energy of 13 TeV. Along with increase in luminosity, this greatly extends the sensitivity of ATLAS experiment to heavy new particles at TeV scale. In particular, many new physics models beyond the Standard Model manifest themselves through significant coupling to the Higgs boson in decays of new particles to a Higgs boson and other SM particles. In this work, two searches for resonances decaying to either pair of Higgs bosons or a Higgs boson associated with another SM vector boson in all hadronic final states are presented using data collected by ATLAS during Run 2...

Interaction between emotional state and learning underlies mood instability

OpenAIRE

Eldar, Eran; Niv, Yael

2015-01-01

Intuitively, good and bad outcomes affect our emotional state, but whether the emotional state feeds back onto the perception of outcomes remains unknown. Here, we use behaviour and functional neuroimaging of human participants to investigate this bidirectional interaction, by comparing the evaluation of slot machines played before and after an emotion-impacting wheel-of-fortune draw. Results indicate that self-reported mood instability is associated with a positive-feedback effect of emotion...

Circuit QED: generation of two-transmon-qutrit entangled states via resonant interaction

Science.gov (United States)

Ye, Xi-Mei; Zheng, Zhen-Fei; Lu, Dao-Ming; Yang, Chui-Ping

2018-04-01

We present a way to create entangled states of two superconducting transmon qutrits based on circuit QED. Here, a qutrit refers to a three-level quantum system. Since only resonant interaction is employed, the entanglement creation can be completed within a short time. The degree of entanglement for the prepared entangled state can be controlled by varying the weight factors of the initial state of one qutrit, which allows the prepared entangled state to change from a partially entangled state to a maximally entangled state. Because a single cavity is used, only resonant interaction is employed, and none of identical qutrit-cavity coupling constant, measurement, and auxiliary qutrit is needed, this proposal is easy to implement in experiments. The proposal is quite general and can be applied to prepare a two-qutrit partially or maximally entangled state with two natural or artificial atoms of a ladder-type level structure, coupled to an optical or microwave cavity.

Measurement of the Top Quark Mass Using the Matrix Element Technique in Dilepton Final States

CERN Document Server

Abazov, Victor Mukhamedovich

2016-08-18

We present a measurement of the top quark mass in ppbar collisions at a center-of-mass energy of 1.96 TeV at the Fermilab Tevatron collider. The data were collected by the D0 experiment corresponding to an integrated luminosity of 9.7 fb-1. The matrix element technique is applied to ttbar events in the final state containing leptons (electrons or muons) with high transverse momenta and at least two jets. The calibration of the jet energy scale determined in the lepton + jets final state of ttbar decays is applied to jet energies. This correction provides a substantial reduction in systematic uncertainties. We obtain a top quark mass of mt = 173.93 +- 1.84 GeV.

Multi-State Vibronic Interactions in Fluorinated Benzene Radical Cations.

Science.gov (United States)

Faraji, S.; Köppel, H.

2009-06-01

Conical intersections of potential energy surfaces have emerged as paradigms for signalling strong nonadiabatic coupling effects. An important class of systems where some of these effects have been analyzed in the literature, are the benzene and benzenoid cations, where the electronic structure, spectroscopy, and dynamics have received great attention in the literature. In the present work a brief overview is given over our theoretical treatments of multi-mode and multi-state vibronic interactions in the benzene radical cation and some of its fluorinated derivatives. The fluorobenzene derivatives are of systematic interest for at least two different reasons. (1) The reduction of symmetry by incomplete fluorination leads to a disappearance of the Jahn-Teller effect present in the parent cation. (2) A specific, more chemical effect of fluorination consists in the energetic increase of the lowest σ-type electronic states of the radical cations. The multi-mode multi-state vibronic interactions between the five lowest electronic states of the fluorobenzene radical cations are investigated theoretically, based on ab initio electronic structure data, and employing the well-established linear vibronic coupling model, augmented by quadratic coupling terms for the totally symmetric vibrational modes. Low-energy conical intersections, and strong vibronic couplings are found to prevail within the set of tilde{X}-tilde{A} and tilde{B}-tilde{C}-tilde{D} cationic states, while the interactions between these two sets of states are found to be weaker and depend on the particular isomer. This is attributed to the different location of the minima of the various conical intersections occurring in these systems. Wave-packet dynamical simulations for these coupled potential energy surfaces, utilizing the powerful multi-configuration time-dependent Hartree method are performed. Ultrafast internal conversion processes and the analysis of the MATI and photo-electron spectra shed new light

2016-01-01

The measurement of Higgs pair production will be a cornerstone of the LHC program in the coming years. Double Higgs production provides a crucial window upon the mechanism of electroweak symmetry breaking and has a unique sensitivity to the Higgs trilinear coupling. We study the feasibility of a measurement of Higgs pair production in the [Formula: see text] final state at the LHC. Our analysis is based on a combination of traditional cut-based methods with state-of-the-art multivariate techniques. We account for all relevant backgrounds, including the contributions from light and charm jet mis-identification, which are ultimately comparable in size to the irreducible 4 b QCD background. We demonstrate the robustness of our analysis strategy in a high pileup environment. For an integrated luminosity of [Formula: see text] ab[Formula: see text], a signal significance of [Formula: see text] is obtained, indicating that the [Formula: see text] final state alone could allow for the observation of double Higgs production at the High Luminosity LHC.

Photoproduction of ρ mesons with a final state proton

International Nuclear Information System (INIS)

Karschnick, O.

2001-06-01

The elastic photoproduction of ρ mesons is studied with the H1 detector for the first time by measuring the final state proton using the forward proton spectrometer. In these reactions the proton is scattered under small angles θ p -1 . The photon-proton center-of-mass energy in this analysis is in the range 25 GeV 2 2 at the proton vertex. The distribution of the π + π - invariant mass is found to be skewed. In the Soeding Model this is attributed to an interference between resonant and non-resonant production of π + π - pairs. The amount of skewing increases with decreasing vertical stroke t vertical stroke as expected. A variation with W is not observed. (orig.)

Measurement of top quark polarization in top-antitop lepton+jets final states at D0

Energy Technology Data Exchange (ETDEWEB)

Augsten, Kamil [Czech Technical Univ., Prague (Czech Republic)

2016-01-01

This thesis presents a measurement of the top quark polarization in the $t\\overline{t}$ events produced in $p\\overline{p}$ collisions at $\\sqrt{s}=1.96$ TeV using data corresponding to 9.7 fb$^{-1}$ of integrated luminosity collected with the D0 detector at the Fermilab Tevatron Collider. The final states used in the measurement contain one lepton and at least three jets. The polarization is measured using the angular distribution of leptons along three different axes: the beam axis, the helicity axis, and the transverse axis normal to the $t\\overline{t}$ production plane. This is the first measurement of top quark polarization at the Tevatron Collider in lepton+jets final states, and the first measurement of transverse polarization in $t\\overline{t}$ production. The polarization along the beam axis is combined with the previous result in the dilepton final states by the D0 experiment. The observed distributions are consistent with the Standard Model of nearly no polarization and no indication for beyond Standard Model physics is observed. The measurement offers legacy result from unique Tevatron Collider data and provides more information about the top quark production and decays, about the properties of the heaviest elementary particle.

Final State of Ecosystem Containing Grass, Sheep and Wolves with Aging

Science.gov (United States)

He, Mingfeng; Pan, Qiu-Hui; Wang, Shuang

This paper describes a cellular automata model containing movable wolves, sheep and reproducible grass. Each wolf or sheep is characterized by Penna bitstrings. In addition, we introduce the energy rule and the predator-prey mechanism for wolf and sheep. With considering age-structured, genetic strings, minimum reproduction age, cycle of the reproduction, number of offspring, we get three possible states of a predator-prey system: the coexisting one with predators and prey, the absorbing one with prey only, and the empty one where no animal survived. In this paper, we mainly discuss the effect of the number of poor genes, the energy supply (food), the minimum reproduction age, the reproductive cycle and the birth rate on the above three possible final states.

We give the intrinsic states explicitly in the boson representation in the framework of the sdg interacting boson model. Although they are only valid in the large-N limit, they are useful to estimate various physical quantities in well deformed nuclei. One can compare these results with those predicted in the IBM1 or in the IBM2.

Anisotropic Surface State Mediated RKKY Interaction Between Adatoms on a Hexagonal Lattice

Science.gov (United States)

Einstein, Theodore; Patrone, Paul

2012-02-01

Motivated by recent numerical studies of Ag on Pt(111), we derive a far-field expression for the RKKY interaction mediated by surface states on a (111) FCC surface, considering the effect of anisotropy in the Fermi edge. The main contribution to the interaction comes from electrons whose Fermi velocity vF is parallel to the vector R connecting the interacting adatoms; we show that in general, the corresponding Fermi wave-vector kF is not parallel to R. The interaction is oscillatory; the amplitude and wavelength of oscillations have angular dependence arising from the anisotropy of the surface state band structure. The wavelength, in particular, is determined by the component of the aforementioned kF that is parallel to R. Our analysis is easily generalized to other systems. For Ag on Pt(111), our results indicate that the RKKY interaction between pairs of adatoms should be nearly isotropic and so cannot account for the anisotropy found in the studies motivating our work.

Approximate and Conditional Teleportation of an Unknown Atomic State Without Bell-State Measurement with Two-Photon Interaction

Institute of Scientific and Technical Information of China (English)

CHEN Chang-Yong

2006-01-01

A scheme for approximately and conditionally teleporting an unknown atomic state via two-photon interaction in cavity QED is proposed. It is the extension of the scheme of Ref. [11] [Phys. Rev. A 69 (2004) 064302], which is based on Jaynes-Cummings model in QED and where only a time point of system evolution and the corresponding fidelity implementing the teleportation are given. In our scheme, the two-photon interaction Jaynes-Cummings model is used to realize the approximate and conditional teleportation. Our scheme does not involve the Bell-state measurement and an additional atom, only requiring two atoms and one single-mode cavity. The fidelity of the scheme is higher than that of Ref. [11]. The scheme may be generalized to not only the teleportation of the state of a cavity mode to another mode by means of a single atom but also the teleportation of the state of a trapped ion.

Effective dark energy equation of state in interacting dark energy models

Avelino, P.P.; Silva, H.M.R. da

2012-01-01

In models where dark matter and dark energy interact non-minimally, the total amount of matter in a fixed comoving volume may vary from the time of recombination to the present time due to energy transfer between the two components. This implies that, in interacting dark energy models, the fractional matter density estimated using the cosmic microwave background assuming no interaction between dark matter and dark energy will in general be shifted with respect to its true value. This may result in an incorrect determination of the equation of state of dark energy if the interaction between dark matter and dark energy is not properly accounted for, even if the evolution of the Hubble parameter as a function of redshift is known with arbitrary precision. In this Letter we find an exact expression, as well as a simple analytical approximation, for the evolution of the effective equation of state of dark energy, assuming that the energy transfer rate between dark matter and dark energy is described by a simple two-parameter model. We also provide analytical examples where non-phantom interacting dark energy models mimic the background evolution and primary cosmic microwave background anisotropies of phantom dark energy models.

Search for Randall-Sundrum Gravitons in Dilepton and Diphoton Final States with 1 fb^-1 of Data

Energy Technology Data Exchange (ETDEWEB)

Das, Amitabha [Boston Univ., MA (United States)

2007-05-01

The work presented in this thesis is the search for Randall-Sundrum (RS) gravitons from an analysis of approximately 1 fb^-1 data collected with the D0 detector at Fermilab. The standard model has been a great success in explaining all experimental observations in particle physics. However, we also know that it has fundamental problems. One of these problems, called the hierarchy problem, is related to the large difference between the electroweak scale and the Planck scale. The model proposed by Randall and Sundrum presents a possible solution to the hierarchy problem by introducing physics beyond the standard model. Randall and Sundrum's theory postulates the existence of a 4th spatial dimension in addition to the conventional (3+1)-dimensional space. Gravity is localized on a 3+1 dimensional subspace, called a brane (Planck brane) that is separated in this new 4th spatial dimension from the standard model brane. As one moves away from this Planck brane, gravity is exponentially suppressed and this explains why gravity appears so weak at the standard model brane. In the simplest RS model, the only particles that propagate in the extra dimension are gravitons. The graviton manifests itself on the standard model brane as a series of excited states that couple to standard model particles with similar strength as the electroweak interaction. The ground state is the massless graviton and the order of magnitude of the mass of the lowest excited state is expected to be one TeV. The first excited mode of the graviton might be produced resonantly at the Tevatron. Gravitons can decay into fermion-antifermion or diboson pairs. Here I search for gravitons through their decay to e⁺e^- and γγ final states. These final states have similar signatures in our detector and can thus be treated together. After analyzing the data I do not find any excess over standard model expectations and set an upper limit on the production rate of such

Absorbing multicultural states in the Axelrod model

Science.gov (United States)

Vazquez, Federico; Redner, Sidney

2005-03-01

We determine the ultimate fate of a limit of the Axelrod model that consists of a population of leftists, centrists, and rightists. In an elemental interaction between agents, a centrist and a leftist can both become centrists or both become leftists with equal rates (similarly for a centrist and a rightist), but leftists and rightists do not interact. This interaction is applied repeatedly until the system can no longer evolve. The constraint between extremists can lead to a frustrated final state where the system consists of only leftists and rightists. In the mean field limit, we can view the evolution of the system as the motion of a random walk in the 3-dimensional space whose coordinates correspond to the density of each species. We find the exact final state probabilities and the time to reach consensus by solving for the first-passage probability of the random walk to the corresponding absorbing boundaries. The extension to a larger number of states will be discussed. This approach is a first step towards the analytic solution of Axelrod-like models.

2018-01-25

The work discussed here is an extension of work previously funded by U.S. Department of Energy Grant DE-FG02-97ER41025. Measurements of charged pion photoproduction from deuterium using the Laser Electron Gamma Source (LEGS) at the Brookhaven National Laboratory previously made by us, as members of the LEGS Collaboration, resulted in the most interesting result of two decades of work. By measuring the production of a charged pion (π⁺) in coincidence with an emitted photon we observed structures in the residual two-nucleon system. These indicated the existence of rare, long-lived states not explicable by standard nuclear theory; they suggested a set of configurations not explicable in terms of a nucleon-nucleon pair. The existence of such “exotic” structures has formed the foundation for most of the work that has ensued. Several measurements at various laboratories have supported, but not proved, the existence of these exotic states. The rarity of these states made their existence undetectable in most previous measurements. Only by observing characteristic signatures of such states (i.e., decay photons), by using very specific kinematics which isolate certain reaction products, or by measuring polarization-dependent observables. During the period of this grant we pursued and made progress on the development of experiments to be performed at the High Intensity Gamma Source (HIGS) of the Tri Universities Nuclear Laboratory (TUNL). Our understanding of photon- and electron-induced nuclear reactions depends on understanding of the basic electron and photon interaction. Recently, the issue of two-photon contributions has arisen in the context of deeply inelastic electron scattering. One way to address this is to measure asymmetries in the Bethe-Heitler ee process. We also made progress in developing the detectors required to measure these asymmetries at HIGS. During the last several years the apparent discrepancy between the size of the proton as measured

Simulation of coherent interactions between Rydberg atoms

2004-01-01

The results of a theoretical investigation of the coherent interaction between many Rydberg atoms are reported. The atoms are assumed to move very little during the time range we investigate. We describe the basic interaction between atoms and show that (contrary to previous theoretical studies) the interaction between the atoms can be coherent. The band structure for a perfect lattice of atoms and the density of states for an amorphous distribution of atoms are presented. We also give results for when the atoms are roughly positioned in a lattice. Finally, we performed detailed calculations to understand when the Rydberg interactions are too strong for an essential states type of approximation. The relevance of our results to previous measurements in a Rydberg gas and to possible future experiments is discussed

Energy independent scaling of the ridge and final state description of high multiplicity p +p collisions at √{s }=7 and 13 TeV

Science.gov (United States)

Sarkar, Debojit

2018-02-01

An energy independent scaling of the near-side ridge yield at a given multiplicity has been observed by the ATLAS and the CMS collaborations in p +p collisions at √{s }=7 and 13 TeV. Such a striking feature of the data can be successfully explained by approaches based on initial state momentum space correlation generated due to gluon saturation. In this paper, we try to examine if such a scaling is also an inherent feature of the approaches that employ strong final state interaction in p +p collisions. We find that hydrodynamical modeling of p +p collisions using EPOS 3 shows a violation of such scaling. The current study can, therefore, provide important new insights on the origin of long-range azimuthal correlations in high multiplicity p +p collisions at the LHC energies.

Search for new physics in final states with a high energy electron and large missing transverse energy

CERN Document Server

AUTHOR|(INSPIRE)INSPIRE-00345099

The most successful and comprehensive theory describing the microcosm is the Standard Model of particle physics (SM). It comprises all known elementary particles and describes in high precision the basic processes of three of the four fundamental interactions. But still, not all experimental observations and theoretical challenges are covered. Many models exist that take the SM as a good approximation of natural phenomena in already discovered energy regions, but extend it in various ways. The Large Hadron Collider (LHC) provides the opportunity to look into these high energy regions using proton-proton collisions at significantly higher center-of-mass energies than previous experiments. This dissertation searches for physics beyond the SM especially in final states with one highly energetic electron (respectively positron) and large missing transverse energy. With the data set recorded in 2012 by the ATLAS detector, a large multi-purpose detector making use of the LHC, the spectrum of the related combined ...

Interaction of an atom subject to an intense laser field with its own radiation field and nonlocality of electromagnetic interaction

International Nuclear Information System (INIS)

Gainutdinov, R Kh; Mutygullina, A A

2009-01-01

We discuss the interaction of an atom subject to an intense driving laser field with its own radiation field. In contrast to the states of bare atoms, the energy difference between some dressed states with the same total angular momentum, its projection and parity may be very small. The self-interaction of a combined atom-laser system associated with nonradiative transitions between such states is effectively strong. We show that the contribution to the radiative shift of the sidebands of the Mollow spectrum, which comes from such processes, is very significant and may be much larger than the trivial Lamb shift, which is the simple redistribution of the Lamb shifts of the corresponding bare states. In the final part, we discuss the possibility that in the Mollow spectrum nonlocality of electromagnetic interaction, which in other cases is hidden in the regularization and renormalization procedures, can manifest itself explicitly.

Exclusive final states from photon-photon collisions at SPEAR

International Nuclear Information System (INIS)

Burke, D.L.

1981-05-01

Studies of exclusive final states produced by the two-photon process have been made at SPEAR by the Mark II and by the Crystal Ball Collaborations. Measurements of π + π - and π 0 π 0 production in the mass region 500 MeV/c 2 2 are presented. These data include strong signals from the well-known f(1270) meson. The A 2 (1310) has been observed via its π 0 eta decay mode and its partial width to γγ has been determined. A measurement of the cross section for the reaction γγ → π + π - π + π - is reported. This channel is found to be small just above the four pion threshold, but exhibits a large enhancement near the rho 0 rho 0 threshold

Parental and Infant Gender Factors in Parent-Infant Interaction: State-Space Dynamic Analysis.

Cerezo, M Angeles; Sierra-García, Purificación; Pons-Salvador, Gemma; Trenado, Rosa M

2017-01-01

This study aimed to investigate the influence of parental gender on their interaction with their infants, considering, as well, the role of the infant's gender. The State Space Grid (SSG) method, a graphical tool based on the non-linear dynamic system (NDS) approach was used to analyze the interaction, in Free-Play setting, of 52 infants, aged 6 to 10 months, divided into two groups: half of the infants interacted with their fathers and half with their mothers. There were 50% boys in each group. MANOVA results showed no differential parenting of boys and girls. Additionally, mothers and fathers showed no differences in the Diversity of behavioral dyadic states nor in Predictability. However, differences associated with parent's gender were found in that the paternal dyads were more "active" than the maternal dyads: they were faster in the rates per second of behavioral events and transitions or change of state. In contrast, maternal dyads were more repetitive because, once they visited a certain dyadic state, they tend to be involved in more events. Results showed a significant discriminant function on the parental groups, fathers and mothers. Specifically, the content analyses carried out for the three NDS variables, that previously showed differences between groups, showed particular dyadic behavioral states associated with the rate of Transitions and the Events per Visit ratio. Thus, the transitions involving 'in-out' of 'Child Social Approach neutral - Sensitive Approach neutral' state and the repetitions of events in the dyadic state 'Child Play-Sensitive Approach neutral' distinguished fathers from mothers. The classification of dyads (with fathers and mothers) based on this discriminant function identified 73.10% (19/26) of the father-infant dyads and 88.5% (23/26) of the mother-infant dyads. The study of father-infant interaction using the SSG approach offers interesting possibilities because it characterizes and quantifies the actual moment-to-moment flow

On the dynamical fluctuations in the multiparticle final states of $e^{+}e^{-}$ collisions

1999-01-01

The scaling property of factorial moments in the multiparticle final- states of e/sup +/e/sup -/ collisions is studied in both the laboratory and the thrust-axis coordinate systems by using the Jetset generator. It turns out that in both of the two cases, the 3- dimensional lnF/sub 2/~lnM are approximately straight lines when the phase space are divided isotropically in different directions, showing that the dynamical fluctuations in the multiparticle final- state of e/sup +/e/sup $/collisions are approximately isotropic. In the lab system, the three gamma parameters obtained by fitting F/sub 2/~M of p/sub x/, p/sub y/, p/sub z/ to Ochs formula respectively are approximately equal. In the thrust system, the three gamma values obtained by fitting F/sub 2/(y)~M, F/sub 2/(p/sub t/)~M and F/sub 2/( phi )~M are also close to each other provided the starting point in fitting F/sub 2/( phi )~M is chosen appropriately. All of these provide further evidence for the above assertion. Our results show that the essential ...

D-state Rydberg electrons interacting with ultracold atoms

Energy Technology Data Exchange (ETDEWEB)

Krupp, Alexander Thorsten

2014-10-02

This thesis was established in the field of ultracold atoms where the interaction of highly excited D-state electrons with rubidium atoms was examined. This work is divided into two main parts: In the first part we study D-state Rydberg molecules resulting from the binding of a D-state Rydberg electron to a ground state rubidium atom. We show that we can address specific rovibrational molecular states by changing our laser detuning and thus create perfectly aligned axial or antialigned toroidal molecules, in good agreement with our theoretical calculations. Furthermore the influence of the electric field on the Rydberg molecules was investigated, creating novel states which show a different angular dependence and alignment. In the second part of this thesis we excite single D-state Rydberg electrons in a Bose-Einstein condensate. We study the lifetime of these Rydberg electrons, the change of the shape of our condensate and the atom losses in the condensate due to this process. Moreover, we observe quadrupolar shape oscillations of the whole condensate created by the consecutive excitation of Rydberg atoms and compare all results to previous S-state measurements. In the outlook we propose a wide range of further experiments including the proposal of imaging a single electron wavefunction by the imprint of its orbit into the Bose-Einstein condensate.

This talk summarises recent ATLAS results on inclusive searches for supersymmetric squarks of the first two generations, and gluinos.

Search for heavy resonances decaying into the fully hadronic di-tau final state with the ATLAS detector

CERN Document Server

Morgenstern, Marcus Matthias

The discovery of a heavy neutral particle would be a direct hint for new physics beyond the Standard Model. In this thesis searches for new heavy neutral particles decaying into two tau leptons, which further decay into hadrons, are presented. They cover neutral Higgs bosons in the context of the minimal supersymmetric extension of the Standard Model (MSSM) as well as $Z'$ bosons, predicted by various theories with an extended gauge sector. Both analyses are based on the full 2012 proton-proton collision dataset taken by the ATLAS experiment at the Large Hadron Collider (LHC). The extended Higgs sector in the MSSM suggests additional heavy neutral Higgs bosons which decay into tau leptons in about 10\\% of the time. Given that the dominant final state, $\\phi\\to b\\bar{b}$, suffers from tremendous QCD initiated backgrounds, the decay into two tau leptons is the most promising final state to discover such new resonances. The fully hadronic final state is the dominant one with a branching fraction of about 42\\%. I...

Random interactions, isospin, and the ground states of odd-A and odd-odd nuclei

International Nuclear Information System (INIS)

Horoi, Mihai; Volya, Alexander; Zelevinsky, Vladimir

2002-01-01

It was recently shown that the ground state quantum numbers of even-even nuclei have a high probability to be reproduced by an ensemble of random but rotationally invariant two-body interactions. In the present work we extend these investigations to odd-A and odd-odd nuclei, considering in particular the isospin effects. Studying the realistic shell model as well as the single-j model, we show that random interactions have a tendency to assign the lowest possible total angular momentum and isospin to the ground state. In the sd shell model this reproduces correctly the isospin but not the spin quantum numbers of actual odd-odd nuclei. An odd-even staggering effect in probability of various ground state quantum numbers is present for even-even and odd-odd nuclei, while it is smeared out for odd-A nuclei. The observed regularities suggest the underlying mechanism of bosonlike pairing of fermionic pairs in T=0 and T=1 states generated by the off-diagonal matrix elements of random interactions. The relation to the models of random spin interactions is briefly discussed

Experimental results with boosted top quarks in the final state

CERN Document Server

Erdmann, Johannes

2014-01-01

An overview of analyses using data at sqrt(s) = 7 TeV and 8 TeV of proton-proton collisions at the LHC is presented. These analyses use boosted techniques to search for new phenomena involving top quarks and to measure the production of top quarks at high transverse momenta. Such techniques involve top-quark tagging algorithms, boson-tagging algorithms, and strategies for b-tagging and lepton identification in the environment where the top quark decay products are close to each other. The strategies are optimized for the different final states and for different ranges of the transverse momenta of the particles involved, improving on traditional resolved analysis strategies.

COMPASS is a fixed-target experiment at the CERN SPS, which investigates the structure and spectroscopy of hadrons. In 2004, a first run with a 190 GeV/c {pi}{sup -} beam took place using nuclear targets. Diffractive dissociation reactions observed in this run provide clean access to meson resonances with masses up to 3 GeV/c{sup 2}. Exclusive final states with 5 charged pions have been extracted. The covered range in momentum transfer extends from threshold to a few GeV{sup 2}/c{sup 2} allowing to study resonance production in different regimes. We report on the status of the analysis of this unique data set.

Search for new phenomena in monophoton final states in proton–proton collisions at s=8 TeV

Directory of Open Access Journals (Sweden)

V. Khachatryan

2016-04-01

Full Text Available Results are presented from a search for new physics in final states containing a photon and missing transverse momentum. The data correspond to an integrated luminosity of 19.6 fb−1 collected in proton–proton collisions at s=8 TeV with the CMS experiment at the LHC. No deviation from the standard model predictions is observed for these final states. New, improved limits are set on dark matter production and on parameters of models with large extra dimensions. In particular, the first limits from the LHC on branon production are found and significantly extend previous limits from LEP and the Tevatron. An upper limit of 14.0 fb on the cross section is set at the 95% confidence level for events with a monophoton final state with photon transverse momentum greater than 145 GeV and missing transverse momentum greater than 140 GeV.

Results of a search for new phenomena in final states with an energetic jet and large missing transverse momentum are reported. The search uses 20.3 fb${}^{-1}$ of $\\sqrt{s}=8$ TeV data collected in 2012 with the ATLAS detector at the LHC. Events are required to have at least one jet with $p_T > 120$ GeV and no leptons. Nine signal regions are considered with increasing missing transverse momentum requirements between $E_{\\mathrm{T}}^{\\mathrm{miss}} >150$ GeV and $E_{\\mathrm{T}}^{\\mathrm{miss}} > 700$ GeV. Good agreement is observed between the number of events in data and Standard Model expectations. The results are translated into exclusion limits on models with large extra spatial dimensions, pair production of weakly interacting dark matter candidates, and production of very light gravitinos in a gauge-mediated supersymmetric model. In addition, limits on the production of an invisibly decaying Higgs-like boson leading to similar topologies in the final state are presented.

Improving regulatory effectiveness in Federal/State siting actions. Success factor evaluation panel. Final report

International Nuclear Information System (INIS)

Haggard, J.

1977-06-01

An independent appraisal of the factors that determine efficiency in reaching environmental decisions with respect to nuclear facilities was addressed. The Panel recommended to substitute 'effectiveness' for 'efficiency.' Thus, an effective decision is: 'A timely final decision, that provides for necessary change, consistent with societal objectives and law, and which is equitable and practical, and is based upon fully and candidly expressed premises utilizing a commonly available data base.' The measurement criteria for evaluating the effectiveness of the environmental decision making process are: timely decision, final decision, provision for change, consistency with societal goals and law, equitable, practical, fully and candidly expressed premises, commonly available data base, and public confidence. The Panel evaluated the 8 policies proposed by NRC staff as essential to licensing reform: national fuels policy, regional review, early disclosure, State role, technical assistance to State, role of utilities, radiation health and safety, and modification of the Atomic Energy Act. The five NRC scenarios were evaluated in terms of regulatory effectiveness

Search for MSSM Higgs Bosons in Tau Final States with the D0 Detector

International Nuclear Information System (INIS)

Yang, Wan-Ching

2010-01-01

The cross-section times branching ratio of the Higgs boson decaying to τ + τ - final state in the Standard Model (SM) is too small to play any role in the SM Higgs boson searches. This, however, is different in the Minimal Supersymmetric Standard Model (MSSM), which predicts two Higgs doublets leading to five Higgs bosons: a pair of charged Higgs boson (H ± ); two neutral CP-even Higgs bosons (h,H) and a CP-odd Higgs boson (A). A search for the production of neutral Higgs bosons decaying into τ + τ - final states in p(bar p) collisions at a centre-of-mass energy of √s = 1.96 TeV is presented in this thesis. One of the two τ leptons is required to decay into a muon while the other decays hadronically. The integrated luminosity is L = 1.0-5.36 fb -1 , collected by the D0 experiment at the Fermilab Tevatron Collider from 2002 to 2009 in the Run II.

Interaction of relativistic elementary atoms with matter. I. General formulas

International Nuclear Information System (INIS)

Mrowczyn'ski, S.

1987-01-01

The problem of the interaction of relativistic elementary atoms (Coulomb bound states of elementary particles such as positronium, pionium, etc.) with matter is studied in the reference frame where the atom is initially at rest. An atom of matter is treated as a spinless structureless fast particle. The amplitudes of elementary-atom interaction are derived in the Born approximation under the assumption that a momentum transfer to the atom does not significantly exceed an inverse Bohr radius of the atom. The elementary-atom excitation and ionization processes are considered. The transitions where the spin projection of the atom component is reversed are also studied. In particular the matrix elements for para-ortho and ortho-para transitions are given. The spin structure of the amplitudes is discussed in detail. The sum rules, which allow the calculation of the cross sections summed over atom final states are found. Finally the formulas of the atom interaction cross sections are presented

Cross-section measurements of final states with photons and jets with the ATLAS experiment

Science.gov (United States)

Pérez, Miguel Villaplana

2018-01-01

The ATLAS Collaboration has performed precise measurements of the cross-section of final states with photons and/or jets at centre-of-mass energies of 8 and 13 TeV. The results are compared with state-of-the-art theory predictions and with predictions of several Monte Carlo generators. We also present new measurements of transverse energy-energy correlations and their associated asymmetries in multi-jet events at 8 TeV. Both measurements are used to extract the strong coupling constant and test the renormalization group equations.

Search for strongly interacting supersymmetric particles decaying to final states with an isolated lepton with the ATLAS detector at the LHC

International Nuclear Information System (INIS)

Lorenz, Jeanette Miriam

2014-01-01

Two analyses searching for squarks and gluinos which decay into final states with multiple jets, an isolated electron or muon and a large missing transverse energy are presented. Both rely on data taken by the ATLAS detector in pp collisions at a center-of-mass energy of 8 TeV at the LHC during 2012. The first analysis uses a subset of 5.8 fb -1 of this dataset, the other analysis uses the full statistics of 20.3 fb -1 . Both analysis share the same methods regarding the triggers and the background estimation techniques. The two dominant backgrounds are t anti t and W+jets production. The t anti t and the W+jets backgrounds are estimated in a semi-data-driven method. The minor QCD multi-jet background is estimated in an entirely data-driven method. The final background estimates in the analyses are derived in a profile-log-likelihood fit. None of the analyses sees an excess beyond Standard Model expectations. The analysis of the partial dataset derives limits in a MSUGRA/CMSSM model with parameters A 0 =0, tanβ=10 and μ>0 and excludes squarks and gluinos with masses below 1.2 TeV for equal squark and gluino masses. The analysis of the full dataset derives limits in simplified models and in a MSUGRA/CMSSM model with parameters A 0 =-2m 0 , tanβ=30 and μ>0. Gluinos (squarks) with masses below 1.2 TeV (750 GeV) can be excluded for vanishing χ 0 1 masses in simplified models. Gluino masses below 1.2 TeV can be excluded for every m 0 value in the MSUGRA/CMSSM model.

Nonequilibrium steady states and resonant tunneling in time-periodically driven systems with interactions

Science.gov (United States)

Qin, Tao; Hofstetter, Walter

2018-03-01

Time-periodically driven systems are a versatile toolbox for realizing interesting effective Hamiltonians. Heating, caused by excitations to high-energy states, is a challenge for experiments. While most setups so far address the relatively weakly interacting regime, it is of general interest to study heating in strongly correlated systems. Using Floquet dynamical mean-field theory, we study nonequilibrium steady states (NESS) in the Falicov-Kimball model, with time-periodically driven kinetic energy or interaction. We systematically investigate the nonequilibrium properties of the NESS. For a driven kinetic energy, we show that resonant tunneling, where the interaction is an integer multiple of the driving frequency, plays an important role in the heating. In the strongly correlated regime, we show that this can be well understood using Fermi's golden rule and the Schrieffer-Wolff transformation for a time-periodically driven system. We furthermore demonstrate that resonant tunneling can be used to control the population of Floquet states to achieve "photodoping." For driven interactions introduced by an oscillating magnetic field near a widely adopted Feshbach resonance, we find that the double occupancy is strongly modulated. Our calculations apply to shaken ultracold-atom systems and to solid-state systems in a spatially uniform but time-dependent electric field. They are also closely related to lattice modulation spectroscopy. Our calculations are helpful to understand the latest experiments on strongly correlated Floquet systems.

Teleportation of N-qubit W State without Bell-State Measurement via Selective Resonant Interaction in Cavity QED

International Nuclear Information System (INIS)

Zhong Wenxue; Geng Jun; Cheng Guangling; Chen Aixi

2010-01-01

We present a scheme in which the N-atom W state is teleported by employing the selective interaction of a cavity field with a driven three-level atom in the A configuration and detecting a single atom in one of the ground states. The long-lived W state is teleported from atom A to atom B when the atoms B and A are sent through a cavity successively and atom A is then detected. The advantage is that the present one does not involve the Bell-state measurement and is robust against the atomic spontaneous emission. (general)

The hadronic final state in the deep inelastic electron-proton scattering. A comparison between the ZEUS data measured 1992 and theoretical models

International Nuclear Information System (INIS)

Schneider, J.L.

1993-12-01

The hadronic final state in deep inelastic e - P collisions has been studied with the 1992 data from the ZEUS detector at HERA. The hadronic final state is described by event topology variables like thrust and sphericity and also by variables like multiplicity and transverse momentum. These quantities require the reconstruction of the particle four moments which are calculated from calorimeter cell clusters (condensates). A detailed Monte-Carlo comparison between final state particles and condensates is presented. ZEUS data and model predictions are compared in the γ * P system. Good agreement between data and models is found in the x-Feynman and transverse momentum spectra and in the seagull plot. Mean thrust and sphericity are measured as functions of the invariant mass W of the hadronic final state. They significantly deviate from the model predictions, as do the mean multiplicities, which exceed the model predictions by about 1 unit. (orig.)

Pairing forces between nucleons in an atomic nucleus strongly influence its structure. One of the manifestations of pair interaction is the ground state multiplet (GSM) formation in the spectrum of low-lying excited states of even–even nuclei. The value of GSM splitting is determined by the value of pair interaction of nucleons; for each isotope, it can be estimated on the basis of experimental nuclear masses. The quality of this estimate is characterized by the degree of reproduction of GSM levels in the nucleus. The GSM systematics in even–even nuclei with a pair of identical nucleons in addition to the filled nuclear core is considered on the basis of delta interaction.

Search for heavy resonances in diboson final states at CMS

CERN Multimedia

CERN. Geneva

2017-01-01

With Run 2 of the LHC in full swing, and very successful data collection at a centre-of-mass energy of 13 TeV, the large dataset collected so far provides a significantly improved sensitivity for discovery of new physics with respect to Run 1. Searches for new resonances in di-boson final states (HH, VH, VV, where V = W, Z) with the CMS detector are presented, including new results. The analyses are optimised for high sensitivity over a large range in resonance mass and consider different spin hypotheses. The performance of jet substructure techniques which are used to identify hadronic decays of highly-boosted W, Z, and H are also discussed.

Quantum dynamics modeled by interacting trajectories

Cruz-Rodríguez, L.; Uranga-Piña, L.; Martínez-Mesa, A.; Meier, C.

2018-03-01

We present quantum dynamical simulations based on the propagation of interacting trajectories where the effect of the quantum potential is mimicked by effective pseudo-particle interactions. The method is applied to several quantum systems, both for bound and scattering problems. For the bound systems, the quantum ground state density and zero point energy are shown to be perfectly obtained by the interacting trajectories. In the case of time-dependent quantum scattering, the Eckart barrier and uphill ramp are considered, with transmission coefficients in very good agreement with standard quantum calculations. Finally, we show that via wave function synthesis along the trajectories, correlation functions and energy spectra can be obtained based on the dynamics of interacting trajectories.

Graphene has intrinsic edge states localized at zigzag edge or lattice defect. Helical boundary states can also be established in such a two-dimensional carbon material at the boundary of topological insulator (TI) phase realized by the extrinsic Rashba spin–orbital coupling (SOC) in gated bilayer graphene. We theoretically investigate the interaction between these two kinds of edge (boundary) states when they coexist in a bilayer graphene. We find that this interaction gives rise to some very interesting results. In a zigzag edged nanoribbon of bilayer graphene, it is possible that the TI helical state does not localize at the TI phase boundary. Instead it moves to the nanoribbon edge even though the SOC is absent therein. In a bulk lattice of bilayer graphene embedded with two line defects, the numbers of helical state subbands at the two line defects are not equal to each other. In such a case, the backscattering lacking is still forbidden since the Kramers pairs are valley polarized. - Highlights: • The TI helical state moves to nanoribbon edge in a gated ZENR-BG. • The gapless modes of LD-BG at the two line defects are not equal to each other. • The Kramers pairs are still valley polarized in a gated LD-BG.

Isolate extended state in the DNA molecular transistor with surface interaction

The field effect characteristic of a DNA molecular device is investigated in a tight binding model with binary disorder and side site correlation. Using the transfer-matrix method and Landauer–Büttiker theory, we find that the system has isolated extended state that is irrespective of the DNA sequence and can be modulated by the gate voltage. When the gate voltage reaches some proper value, the isolated extended state appears at the Fermi level of the system and the long range charge transport is greatly enhanced. We attribute this phenomenon to the combination of the external field, the surface interaction, and the intrinsic disorder of DNA. The result is a generic feature of the nanowire with binary disorder and surface interaction.

In this work we present an analysis of the antiproton-proton annihilations into six body final states with strange particle production at 750 HeV/c. It is shown that these final states are dominated at this energy by resonance production in quasi-three body Intermediate states. We determine the scattering length of the resonanceδ+ (970) which is found to be compatible with earlier determinations. fe also study the production of the resonance ω(783) associated to the system K 0 K 0 in the five body final state and determine Its polarization, which 1s not compatible with that obtained for the p 0 (770) in the final state K 0 K 0 p 0 . The amplitudes should be equal in a quark rearrangement model. (Author) 11 refs

Theory of long-range interactions for Rydberg states attached to hyperfine-split cores

Science.gov (United States)

Robicheaux, F.; Booth, D. W.; Saffman, M.

2018-02-01

The theory is developed for one- and two-atom interactions when the atom has a Rydberg electron attached to a hyperfine-split core state. This situation is relevant for some of the rare-earth and alkaline-earth atoms that have been proposed for experiments on Rydberg-Rydberg interactions. For the rare-earth atoms, the core electrons can have a very substantial total angular momentum J and a nonzero nuclear spin I . In the alkaline-earth atoms there is a single (s ) core electron whose spin can couple to a nonzero nuclear spin for odd isotopes. The resulting hyperfine splitting of the core state can lead to substantial mixing between the Rydberg series attached to different thresholds. Compared to the unperturbed Rydberg series of the alkali-metal atoms, the series perturbations and near degeneracies from the different parity states could lead to qualitatively different behavior for single-atom Rydberg properties (polarizability, Zeeman mixing and splitting, etc.) as well as Rydberg-Rydberg interactions (C5 and C6 matrices).

Diffractive dissociation reactions at the COMPASS experiment, CERN, provide access to the meson resonance spectrum. During a pilot run in 2004, using a pion beam on a lead target, a competitive number of {pi}{sup -} {pi}{sup -} {pi}{sup +} final state events with masses below 2.5 GeV/c{sup 2} were recorded. After COMPASS had finished its muon program in 2007, it used in 2008 again a pion beam, but now a liquid hydrogen target, and gathered during several weeks a unique high statistics. A full partial wave analysis of the 2004 data has been performed, with the focus on the kinematic range of a large momentum transfer (0.1 GeV{sup 2}/c{sup 2} {<=} t' {<=} 1.0 GeV{sup 2}/c{sup 2}). In addition first results of the adjacent analysis with 2008 data are presented.

Decays of beauty baryons to the $D^0 p h^-$ and $\\Lambda_c^+ h^-$ final states (where $h$ indicates a pion or a kaon) are studied using a data sample of $pp$ collisions, corresponding to an integrated luminosity of 1.0 fb$^{-1}$, collected by the LHCb detector. The Cabibbo-suppressed decays $\\Lambda_b^0\\to D^0 p K^-$ and $\\Lambda_b^0\\to \\Lambda_c^+ K^-$ are observed and their branching fractions are measured with respect to the decays $\\Lambda_b^0\\to D^0 p \\pi^-$ and $\\Lambda_b^0\\to \\Lambda_c^+ \\pi^-$. In addition, the first observation is reported of the decay of the neutral beauty-strange baryon $\\Xi_b^0$ to the $D^0 p K^-$ final state, and a measurement of the $\\Xi_b^0$ mass is performed. Evidence of the $\\Xi_b^0\\to \\Lambda_c^+ K^-$ decay is also reported.

Palazzo, Serena

2018-01-01

Measurements of inclusive and differential top quark production cross sections in hadronic final states, including hadronic τ decays, in proton-proton collisions with the ATLAS detector at the Large Hadron Collider are presented at center-of-mass energies of 7, 8 and 13 TeV. The inclusive cross section measurements reach high precision and are compared to other decay modes and the best available theoretical calculations. Differential measurements of the kinematic properties of top quark events are also discussed. These measurements use boosted top quarks, probing our understanding of top quark production in the TeV regime.

Hadronic Multi-Particle Final State Measurements with CLAS at Jefferson Lab

Will Brooks

2002-01-01

Precision measurements in the neutrino sector are becoming increasingly feasible due to the development of relatively high-rate experimental capabilities. These important developments command renewed attention to the systematic corrections needed to interpret the data. Hadronic multi-particle final state measurements made using CLAS at Jefferson Lab, together with a broad theoretical effort that links electro-nucleus and neutrino-nucleus data, will address this problem, and will elucidate long-standing problems in intermediate energy nuclear physics. This new work will ultimately enable precision determinations of fundamental quantities such as the neutrino mixing matrix elements in detailed studies of neutrino oscillations

Based on the results of the study the author notes that the interaction of the Ukrainian SFS customs offices and local state administrations with local self-government bodies is an inherent quality, link and component of the Ukrainian SFS Customs offices functioning organization, which aims to improve the state customs service implementation standards by the Ukrainian SFS customs houses and to ensure the said implementation efficiency. However, in the course of interaction of the Ukrainian SFS customs with local state administrations and local self-government bodies each of the mentioned organizations specializes in solving their specific tasks in accordance with their subject expertise, and forms a clear organizational system. The complementarity of such kind helps to improve the state customs affairs conductance quality and is realized through the coordination of performance of the Ukrainian SFS customs offices, local state administrations and local self-government bodies as the interaction subjects through normative, informational and analytical provision for the interaction and concretization of the activities of each subject within the planned activities.

Charged-current νμ interactions on carbon, iron, and lead with a final state hadronic system of one or more protons with zero mesons are used to investigate the influence of the nuclear environment on quasielasticlike interactions. The transferred four-momentum squared to the target nucleus, Q2, is reconstructed based on the kinematics of the leading proton, and differential cross sections versus Q2 and the cross-section ratios of iron, lead, and carbon to scintillator are measured for the first time in a single experiment. The measurements show a dependence on the atomic number. While the quasielasticlike scattering on carbon is compatible with predictions, the trends exhibited by scattering on iron and lead favor a prediction with intranuclear rescattering of hadrons accounted for by a conventional particle cascade treatment. These measurements help discriminate between different models of both initial state nucleons and final state interactions used in the neutrino oscillation experiments.

Interaction of VUV-photons with molecules. Spectroscopy and dynamics of molecular superexcited states

International Nuclear Information System (INIS)

Hatano, Y.

2002-01-01

Complete text of publication follows. A survey is given of recent progress in experimental studies of the interaction of VUV-photons with molecules, i.e., those of photoabsorption, photoionization, and photodissociation of molecules in the excitation photon energy range of 10-50 eV, with a particular emphasis placed on current understanding of the spectroscopy and dynamics of formed molecular superexcited states. These studies are of great importance in understanding the interaction of ionizing radiation with matter. Molecules studied are ranged from simple diatomic and triatomic molecules to polyatomic molecules such as hydrocarbons. Most of the observed molecular superexcited states are assigned to high Rydber states which are vibrationally, doubly, or inner-core excited and converge to each of ion states. Non-Rydberg superexcited states are also observed. Dissociation into neutral fragments in comparison with ionization is of unexpectedly great importance in the observed decay of each of these state-assigned superexcited molecules. Dissociation dynamics as well as its products of superexcited states are remarkably different from those of lower excited states below about ionization thresholds. Some remarks are also presented of molecules in the condensed phase

The classical Pierce diode: Using particle simulations on linear and nonlinear behavior and final states

International Nuclear Information System (INIS)

Crystal, T.L.; Kuhn, S.; Birdsall, C.K.

The classical Pierce diode is a simple 1-d system of two shorted metal plates, a cold beam of electrons injected from one side and a neutralizing background of rigid ions. While the plasma medium is technically stable, the finiteness of the Pierce system allows stable and unstable operation. It is usefully studied as an archetypical bounded plasma system, related e.g., to Q-machines, particle accelerators, thermionic converters. New particle simulations of the Pierce diode have successfully recovered many novel linear phenomena including the dominant linear eigenmodes (seen in the internal electrostatic fields), and the dominant and subdominant eigenfrequencies, (seen both in the internal electrostatics and in the external circuit current, J/sub ext/(t)). These simulation results conform very well to detailed predictions of a new linear analysis. The final (nonlinear) state recovered can show critical dependence on initial (linear perturbation) conditions, and can be made steady-state (d.c.) or periodic-oscillatory by simply changing the initial conditions by a factor of 10/sup -4/ or less. A third class of final state is also possible which has oscillations which seem to be nonperiodic

Search for MSSM Higgs Bosons in Tau Final States with the D0 Detector

Yang, Wan-Ching [Univ. of Manchester (United Kingdom)

2010-01-01

The cross-section times branching ratio of the Higgs boson decaying to τ⁺τ^- final state in the Standard Model (SM) is too small to play any role in the SM Higgs boson searches. This, however, is different in the Minimal Supersymmetric Standard Model (MSSM), which predicts two Higgs doublets leading to five Higgs bosons: a pair of charged Higgs boson (H^±); two neutral CP-even Higgs bosons (h,H) and a CP-odd Higgs boson (A). A search for the production of neutral Higgs bosons decaying into τ⁺τ^- final states in p{bar p} collisions at a centre-of-mass energy of √s = 1.96 TeV is presented in this thesis. One of the two τ leptons is required to decay into a muon while the other decays hadronically. The integrated luminosity is L = 1.0-5.36 fb ^-1, collected by the D0 experiment at the Fermilab Tevatron Collider from 2002 to 2009 in the Run II.

Two-dimensional partial-wave analysis of exclusive 190 GeV π-p scattering into the π-π-π+ final state at COMPASS (CERN)

International Nuclear Information System (INIS)

Haas, Florian

The dynamics of strong interaction in the regime of low energies, i.e. large distances, is still not understood. Given its simplicity the non-relativistic simple quark model (SQM) describes successfully the observed hadronic spectra. QCD-inspired models, however, predict hadronic states where the gluonic content contributes to the hadron quantum numbers. These so-called hybrids cannot be explained within the SQM. A solid experimental proof of the existence of such systems would be the observation of spin-exotic states, with spin-parity quantum numbers, not allowed in the SQM. The study of mesons, the simplest hadrons, permits to gain insight into the realm of strong interaction where hadrons are the relevant degrees of freedom. The most promising spin-exotic meson candidate is the π 1 (1600), which was claimed in several experiments and in particular in data taken during a previous hadron campaign of the COMPASS experiment. The hadron spectroscopy program of the COMPASS experiment at CERN focuses on the investigation of the light-meson spectrum in order to enlighten this rarely understood regime of strong interaction. During the 2008 data taking an unprecedented statistical precision has been reached in peripheral interactions of 190 GeV/c pions with a proton target leading to the π - π - π + final state. A spin-parity analysis in the kinematical region of the squared fourmomentum transfer 0.1≤t'0≤1.0 GeV 2 /c 2 was carried out based on a model of 88 partial waves up to a total angular momentum of 6. Besides the precise determination of properties of known resonances, a new axial-vector state, the a 1 (1420), was observed for the first time in a mass region where neither model nor lattice calculations predict mesons with this quantum numbers. Noteworthy is the very small intensity of this signal and that it only couples to the f 0 (980) isobar which is assumed to have a large strangeness content. The spin-exotic π 1 (1600) was observed albeit as a

Post-foil interaction in foil-induced molecular dissociation

1985-01-01

The authors have investigated the foil-induced dissociation of 175- 250- keV/amu CH + , NH + , and OH + , FH + and NeH + ions by coincident detection of the fragment atoms. The dissociation energies corresponding to in-foil and post-foil interactions were deduced from the measured relative flight times of the fragment pairs to a set of detectors downstream from the target. The authors considered final states consisting of a) a proton and a heavy-ion and, b) a hydrogen atom and a heavy-ion. Surprisingly, in both cases the energy released in the post-target interaction shows a similar linear increase with the charge state of the heavy partner

Rock-brine chemical interactions. Final report

Energy Technology Data Exchange (ETDEWEB)

1982-02-01

The results of experimental interaction of powdered volcanic rock with aqueous solutions are presented at temperatures from 200 to 400/sup 0/C, 500 to 1000 bars fluid pressure, with reaction durations of approximately 30 days under controlled laboratory conditions. The aim of this research is to develop data on the kinetics and equilibria of rock solution interactions that will provide insight into the complex geochemical processes attending geothermal reservoir development, stimulation, and reinjection. The research was done in the Stanford Hydrothermal Lab using gold cell equipment of the Dickson design. This equipment inverts the solution rock mixture several times a minute to ensure thorough mixing. Solution samples were periodically withdrawn without interruption of the experimental conditions. The data from these experiments suggests a path dependent series of reactions by which geothermal fluids might evolve from meteoric or magmatic sources.

Search for new phenomena in jets plus missing transverse energy final states at the LHC

CERN Document Server

Caminal Armadans, Roger

This Thesis presents a search for new phenomena in $pp$ collisions at $\\sqrt{s} = 8$ TeV recorded with the ATLAS detector at the LHC collider. The final state under investigation is defined by the presence of a very energetic jet, large missing transverse energy, a maximum of three reconstructed jets, and no reconstructed leptons, leading to a monojet-like configuration. The monojet final state constitutes a very clean and distinctive signature for new physics processes. After the discovery of the Higgs and the constraints on the masses of first and second generation squarks and gluinos up to the TeV scale, much attention has been put to searches for third generation squarks. These searches are motivated by naturalness arguments, which point to relatively light stops and sbottoms, and therefore allowing their production at the LHC. The monojet analysis is interpreted in terms of pair production of stops and sbottoms, and in terms of inclusive searches for pair production of squarks, and gluinos. In particula...

Combining extrapolation with ghost interaction correction in range-separated ensemble density functional theory for excited states

Science.gov (United States)

Alam, Md. Mehboob; Deur, Killian; Knecht, Stefan; Fromager, Emmanuel

2017-11-01

The extrapolation technique of Savin [J. Chem. Phys. 140, 18A509 (2014)], which was initially applied to range-separated ground-state-density-functional Hamiltonians, is adapted in this work to ghost-interaction-corrected (GIC) range-separated ensemble density-functional theory (eDFT) for excited states. While standard extrapolations rely on energies that decay as μ-2 in the large range-separation-parameter μ limit, we show analytically that (approximate) range-separated GIC ensemble energies converge more rapidly (as μ-3) towards their pure wavefunction theory values (μ → +∞ limit), thus requiring a different extrapolation correction. The purpose of such a correction is to further improve on the convergence and, consequently, to obtain more accurate excitation energies for a finite (and, in practice, relatively small) μ value. As a proof of concept, we apply the extrapolation method to He and small molecular systems (viz., H2, HeH+, and LiH), thus considering different types of excitations such as Rydberg, charge transfer, and double excitations. Potential energy profiles of the first three and four singlet Σ+ excitation energies in HeH+ and H2, respectively, are studied with a particular focus on avoided crossings for the latter. Finally, the extraction of individual state energies from the ensemble energy is discussed in the context of range-separated eDFT, as a perspective.

Coherent correlated states of interacting particles - the possible key to paradoxes and features of LENR

International Nuclear Information System (INIS)

Vysotskii, Vladimir I.; Vysotskyy, Mykhaylo V.

2015-01-01

In this article, the universal mechanism of optimization of low energy nuclear reactions (LENR) on the basis of coherent correlated states (CCS) of interacting particles is discussed. Formation of these states is the result of special nonstationary low energy action to parameters of potential well containing interacting particles. It was shown that in real nuclear-physical systems usage of CCS leads to sharp growth (up to 10 30 -10 100 and more) of Coulomb barrier penetrability at very low energy of interacting particles. Several successful LENR experiments based on CCS are discussed. (author)

Final report: Mapping Interactions in Hybrid Systems with Active Scanning Probes

Energy Technology Data Exchange (ETDEWEB)

Berezovsky, Jesse [Case Western Reserve Univ., Cleveland, OH (United States)

2017-09-29

This project aimed to study and map interactions between components of hybrid nanodevices using a novel scanning probe approach. To enable this work, we initially constructed a flexible experimental apparatus allowing for simultaneous scanning probe and confocal optical microscopy measurements. This setup was first used for all-optical measurements of nanostructures, with the focus then shifting to hybrid devices in which single coherent electron spins are coupled to micron-scale ferromagnetic elements, which may prove useful for addressing single spins, enhanced sensing, or spin-wave-mediated coupling of spins for quantum information applications. A significant breakthrough was the realization that it is not necessary to fabricate a magnetic structure on a scanning probe – instead a ferromagnetic vortex core can act as an integrated, solid state, scanning probe. The core of the vortex produces a very strong, localized fringe field which can be used analogously to an MFM tip. Unlike a traditional MFM tip, however, the vortex core is scanned within an integrated device (eliminating drift), and can be moved on vastly faster timescales. This approach allows the detailed investigation of interactions between single spins and complex driven ferromagnetic dynamics.

Interaction of D0-brane bound states and Ramond-Ramond photons

International Nuclear Information System (INIS)

Fatollahi, Amir H.

2002-01-01

We consider the problem of the interaction between a D0-brane bound state and one-form Ramond-Ramond (RR) photons using the world-line theory. Based on the fact that in the world-line theory the RR gauge fields depend on the matrix coordinates of D0-branes, the gauge fields also appear as matrices in the formulation. At the classical level, we derive the Lorentz-like equations of motion for D0-branes, and it is observed that the center of mass is colorless with respect to the SU(N) sector of the background. Using the path integral method, the perturbation theory for the interaction between the bound state and the RR background is developed. Qualitative considerations show that the possibility of the existence of a map between the world-line theory and the non-Abelian gauge theory is very considerable

Search for flavour changing neutral currents in top quark production and decays with three-lepton final state using the data collected at sqrt(s) = 13 TeV

CERN Document Server

CMS Collaboration

2017-01-01

A search for flavour changing neutral currents (FCNC) involving a top quark and a Z boson is presented. The analysis uses the 2016 proton collision data collected by the CMS experiment at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.9 fb$^{-1}$. The search focuses on single top quark and top quark pair FCNC interactions observable in three lepton final states, where the FCNC interaction happens at the production or at the top quark decay. No significant deviation is observed from the predicted background. Observed (expected) upper limits at 95$\\%$ confidence level are set on the branching fractions of top quark decays: ${\\mathcal{B}}(t \\rightarrow uZ) < 0.024\\%$ ($0.015\\%$) and ${\\mathcal{B}}(t \\rightarrow cZ) < 0.045\\%$ (0.037$\\%$), assuming one non-vanishing coupling at a time.

Theory and computation of the matrix elements of the full interaction of the electromagnetic field with an atomic state: Application to the Rydberg and the continuous spectrum

International Nuclear Information System (INIS)

Komninos, Yannis; Mercouris, Theodoros; Nicolaides, Cleanthes A.

2002-01-01

We develop practical formulas for the calculation of the matrix elements of the interaction of the electromagnetic field with an atomic state, beyond the long-wavelength approximation. The atom-plus-field Hamiltonian is chosen to have the multipolar form, containing the electric, paramagnetic, and diamagnetic operators. The final workable expressions include the interactions to all orders and are derived by first expanding the fields in partial waves. The electric-field operator reaches a constant value as the radial variable becomes large, contrary to the result of the electric-dipole approximation (EDA) where the value of the corresponding operator increases indefinitely. Applications are given for Rydberg states of hydrogen up to n=50 and for free-free transitions in a Coulomb potential. Such matrix elements are relevant to a number of real and virtual processes occurring during laser-atom interactions. The computation is done numerically, using a combination of analytic with numerical techniques. By comparing the results of the EDA with those of the exact treatment, it is shown that the former is inadequate in such cases. This finding has repercussions on the theory and understanding of the physics of quantum systems in high-lying Rydberg levels and wave packets or in scattering states

Structure functions and final-state properties in deeply inelastic electron-proton scattering

International Nuclear Information System (INIS)

Kharraziha, H.

1997-01-01

In this thesis, we give a description of the detailed structure of the proton and a description of the final-state properties in electron-proton scattering. Qualitative results, in a purely gluonic scenario with the leading log approximation, and quantitative results, where quarks are included and some sub-leading corrections have been made, are presented. The quantitative results are in fair agreement with available experimental data and a Monte Carlo event generator for electron-proton scattering is presented. Further, a computer program for calculating QCD colour factors is presented

Searches for new phenomena in leptonic final states using the ATLAS detector

CERN Document Server

Muskinja, Miha; The ATLAS collaboration

2018-01-01

Resonances decaying to leptons are very common in various BSM theories such as the Grand Unification theory, Left-Right Symmetric model, Sequential Standard Model, Two-Higgs-Doublet model, Higgs triplet, and many more. Final states with leptons have lower backgrounds and are something to trigger on. Furthermore, the detector resolution allows a good measurement of the invariant mass of BSM resonances decaying to electrons and muons. The talk covers several searches for new resonances decaying into electrons and muons and presents the technical challenges, along with the tangible solutions, that these searches are facing.

Measurement of Branching Fractions for Exclusive B Decays to Charmonium Final States

Varnes, Erich

2002-05-13

We report branching fraction measurements for exclusive decays of charged and neutral B mesons into two-body final states containing a charmonium meson. We use a sample of 22.72 {+-} 0.36 million B{bar B} events collected between October 1999 and October 2000 with the BABAR detector at the PEP-II storage rings at the Stanford Linear Accelerator Center.

International Nuclear Information System (INIS)

2006-01-01

We study theoretically the ground state energy of a polaron near the interface of a polar-polar semiconductor by considering the Rashba spin-orbit (SO) coupling with the Lee-Low-Pines intermediate coupling method. Our numerical results show that the Rashba SO interaction originating from the inversion asymmetry in the heterostructure splits the ground state energy of the polaron. The electron areal density and vector dependence of the ratio of the SO interaction to the total ground state energy or other energy composition are obvious. One can see that even without any external magnetic field, the ground state energy can be split by the Rashba SO interaction, and this split is not a single but a complex one. Since the presents of the phonons, whose energy gives negative contribution to the polaron's, the spin-splitting states of the polaron are more stable than electron's.

Probing the pairing interaction through two-neutron transfer reactions

Directory of Open Access Journals (Sweden)

Margueron J.

2012-12-01

Full Text Available The treatment of the pairing interaction in mean-field-based models is addressed. In particular, the possibility to use pair transfers as A tool to better constrain this interaction is discussed. First, pairing inter-actions with various density dependencies (surface/volume mixing are used in the microscopic Hartree-Fock-Bogoliubov + quasiparticle random-phase approximation model to generate the form factors to be used in reaction calculations. Cross sections for (p,t two-neutron transfer reactions are calculated in the one-step zero-range distorted-wave Born approximation for some Tin isotopes and for incident proton energies from 15 to 35 MeV. Three different surface/volume mixings of A zero-range density-dependent pairing interaction are employed in the microscopic calculations and the sensitivity of the cross sections to the different mixings is analyzed. Differences among the three different theoretical predictions are found espacially for the nucleus 136Sn and they are more important at the incident proton energy of 15 MeV. We thus indicate (p,t two-neutron transfer reactions with very neutron-rich Sn isotopes and at proton energies around 15 MeV as good experimental cases where the surface/volume mixing of the pairing interaction may be probed. In the second part of the manuscript, ground-state to ground-state transitions are investigated. Approximations made to estimate two-nucleon transfer probabilities in ground-state to ground-state transitions and the physical interpretation of these probabilities are discussed. Probabilities are often calculated by approximating both ground states of the initial nucleus A and of the final nucleus A±2 by the same quasiparticle vacuum. We analyze two improvements of this approach. First, the effect of using two different ground states with average numbers of particles A and A±2 is quantified. Second, by using projection techniques, the role of particle number restoration is analyzed. Our analysis

Final Report: Multi-State Sharing Initiative

2012-04-01

In 2003 a joint effort between the U.S. Department of Homeland Security (DHS) and the U.S. Department of Justice created state and metropolitan intelligence fusion centers. These fusion centers were an effort to share law enforcement, disaster, and terrorism related information and intelligence between state and local jurisdictions and to share terrorism related intelligence between state and local law enforcement agencies and various federal entities. In 2006, DHS commissioned the Oak Ridge National Laboratory to establish and manage a groundbreaking program to assist local, state, and tribal leaders in developing the tools and methods required to anticipate and forestall terrorist events and to enhance disaster response. This program, called the Southeast Region Research Initiative (SERRI), combines science and technology with validated operational approaches to address regionally unique requirements and suggest regional solutions with the potential for national application. In 2009, SERRI sponsored the Multistate Sharing Initiative (MSSI) to assist state and metropolitan intelligence fusion centers with sharing information related to a wider variety of state interests than just terrorism. While these fusion centers have been effective at sharing data across organizations within their respective jurisdictions, their organizational structure makes bilateral communication with federal entities convenient and also allows information to be further disbursed to other local entities when appropriate. The MSSI-developed Suspicious Activity Report (SAR) sharing system allows state-to-state sharing of non-terrorism-related law enforcement and disaster information. Currently, the MSSI SAR system is deployed in Alabama, Kentucky, Tennessee, and South Carolina. About 1 year after implementation, cognizant fusion center personnel from each state were contacted to ascertain the status of their MSSI SAR systems. The overwhelming response from these individuals was that the MSSI

Study of four-lepton final states in electron-positron interactions at 29 GeV

International Nuclear Information System (INIS)

Petradza, A.

1989-08-01

This thesis presents a study of electron-positron scattering to four light leptons. The motivations behind it are twofold. Firstly, the study is a test of the theory of electron-positron interactions to 4th order in the fine structure constant α. A deviation from the theory could indicate the existence of a heavy new particle. Secondly, a measurement of these processes may prove useful in the understanding of other QED-type reactions. The method for simulating the four-lepton processes by the Monte Carlo event generator of Berends, Daverveldt and Kleiss is described. Theoretical predictions are compared to data from the Mark II and HRS experiments at the PEP storage ring. The observed events consist of four leptons at large angles. Data for all three e + e - e + e - , e + e - μ + μ - and μ + μ - μ + μ - processes are well described by the QED Monte Carlo calculation. The various kinematical distributions are in good agreement with QED to order α 4 . 18 refs., 64 figs., 19 tabs

The simplest diagrams describing interaction with the spectator in the e - π→e - + hadrons deep inelastic process are considered. The contribution of the final state interaction diagram to the structure function considerable in the Feynman gauge is suppressed under the temporal gauge choice in accordance with the results of the naive parton model. The expressin for the cross section of the process when large quark momentum is transferred to the spectator is derived

A theory of the strong interactions

International Nuclear Information System (INIS)

Gross, D.J.

1979-01-01

The most promising candidate for a fundamental microscopic theory of the strong interactions is a gauge theory of colored quarks-Quantum Chromodynamics (QCD). There are many excellent reasons for believing in this theory. It embodies the broken symmetries, SU(3) and chiral SU(3)xSU(3), of the strong interactions and reflects the success of (albeit crude) quark models in explaining the spectrum of the observed hadrons. The hidden quantum number of color, necessary to account for the quantum numbers of the low lying hadrons, plays a fundamental role in this theory as the SU(3) color gauge vector 'gluons' are the mediators of the strong interactions. The absence of physical quark states can be 'explained' by the hypothesis of color confinement i.e. that hadrons are permanently bound in color singlet bound states. Finally this theory is unique in being asymptotically free, thus accounting for the almost free field theory behvior of quarks observed at short distances. (Auth.)

INTERACTING MANY-PARTICLE SYSTEMS OF DIFFERENT PARTICLE TYPES CONVERGE TO A SORTED STATE

DEFF Research Database (Denmark)

Kokkendorff, Simon Lyngby; Starke, Jens; Hummel, N.

2010-01-01

We consider a model class of interacting many-particle systems consisting of different types of particles defined by a gradient flow. The corresponding potential expresses attractive and repulsive interactions between particles of the same type and different types, respectively. The introduced...... system converges by self-organized pattern formation to a sorted state where particles of the same type share a common position and those of different types are separated from each other. This is proved in the sense that we show that the property of being sorted is asymptotically stable and all other...... states are unstable. The models are motivated from physics, chemistry, and biology, and the principal investigations can be useful for many systems with interacting particles or agents. The models match particularly well a system in neuroscience, namely the axonal pathfinding and sorting in the olfactory...

Search for Supersymmetry in final states with jets, missing transverse momentum and at least one lepton with the ATLAS Experiment

CERN Document Server

Janus, Michel

A search for Supersymmetry (SUSY) in final states with at least one lepton and large missing transverse energy based on proton-proton collisions recorded with the ATLAS detector at the LHC is presented. The leptons are reconstructed in the hadronic decay mode. Final states with leptons o er a good sensitivity for SUSY models where the coupling to the third generation of fermions is enhanced, e.g. gauge mediated SUSY breaking (GMSB) models, for which the supersymmetric partner of the lepton is the next-to-lightest SUSY particle (NLSP) and its decay to electrons or muons is strongly suppressed. To search for new physics in final states with hadronic -lepton decays a reliable and e cient re- construction algorithm for hadronic decays is needed to separate real decays and backgrounds from quark- or gluon-initiated jets and electrons. As part of this thesis two existing -reconstruction al- gorithms were further developed and integrated into a single algorithm that has by now become the standard algorithm for recon...

Role of the Coulomb interaction in the low-frequency density of states of DNA double helices

International Nuclear Information System (INIS)

Garcia, A.E.; Krumhansl, J.A.

1988-01-01

The complete vibrational frequency spectrum of several DNA double-helical oligomers is calculated using established pair potentials. Various cutoff values are used for the range of the Coulomb interactions. At very low frequency the integrated density of states shows a noninteger exponent with values ranging from 0.75 to 1.55, depending on the cutoff value for the Coulomb interactions. We conclude that the cumulative densities of states in those molecules depend more on competing interactions than on various proposed universal laws

Marot, L.

2009-09-01

In this final scientific report made by the University of Basel, Switzerland, on-going work on plasma-wall interactions in the International Thermonuclear Experimental Reactor ITER is reported on. The growing interest concerning the use of rhodium (Rh) as a material for the first mirrors in ITER and the necessity of using it as a thin film deposited on a polished substrate has necessitated the development of a robust deposition technique for the preparation of high-reflectivity mirrors. The realisation and tests of high-quality rhodium coated mirrors using magnetron sputtering is reported on. Also, the exposure of the rhodium and molybdenum coated mirrors in the Tokamak fusion reactor system is reported on and the role of carbon and tungsten impurities in the optical degradation of metallic mirrors is looked at. Optical measurements made at the Joint European Torus (JET) are also reported on

Search for WH Associated Production in the l upsilon b-bbar Final State Using the DØ Detector at the Tevatron

Energy Technology Data Exchange (ETDEWEB)

Brown, Jonathan [Paris Diderot Univ. (France)

The Standard Model is the framework which allows to describe interactions between particles and their dynamics. The Higgs mechanism is a solution to naturally introduce a mass term in the theoretical description of this model. After electroweak spontaneous symmetry breaking, a new massive scalar particle is introduced, the Higgs boson. Since it hasn’t been discovered yet, the search for the Higgs boson is carried at the Tevatron, which is a p$\\bar{p}$ collider at a center-of-mass of 1.96 TeV. For M_H <115 GeV, the dominant decay mode is H → b$\\bar{b}$ . The analysis presented in this document is focused on the 100< M_H <150 GeV mass range, in the channel where the Higgs boson is produced in assocation with a W boson which decays either to an electron or muon and a neutrino. The study of this final state relies on informations collected from all parts of the DØ detector. A result based on 5.3 fb^-1 of RunII Tevatron collisions is presented here. In order to increase the sensitivity to the signal, the analysis is separated in different sub-channels according to the lepton flavour, number of jets in the final state, number of jets identified as originated from b quarks and data taking periods. After selecting events, a multivariate analysis technique is used to separate signal-like events from the expected physics and instrumental backgrounds. A good agreement between data and simulation is observed. As no signal excess is observed in data, an observed (expected) upper limit of 4.5 (4.8) for M_H = 115 GeV is set on the ratio of the WH cross section multiplied by the H → b$\\bar{b}$ branching fraction to its standard model prediction, at 95% confidence level. Since the final Tevatron dataset is soon to be analyzed, an effort is brought to achieve the maximum sensitivity. A preliminary analysis updated in Summer 2011 is presented as well as future improvements to be considered in the final publication for the search in

Interaction of solitons and the formation of bound states in the generalized Lugiato-Lefever equation

Science.gov (United States)

Parra-Rivas, Pedro; Gomila, Damia; Colet, Pere; Gelens, Lendert

2017-07-01

Bound states, also called soliton molecules, can form as a result of the interaction between individual solitons. This interaction is mediated through the tails of each soliton that overlap with one another. When such soliton tails have spatial oscillations, locking or pinning between two solitons can occur at fixed distances related with the wavelength of these oscillations, thus forming a bound state. In this work, we study the formation and stability of various types of bound states in the Lugiato-Lefever equation by computing their interaction potential and by analyzing the properties of the oscillatory tails. Moreover, we study the effect of higher order dispersion and noise in the pump intensity on the dynamics of bound states. In doing so, we reveal that perturbations to the Lugiato-Lefever equation that maintain reversibility, such as fourth order dispersion, lead to bound states that tend to separate from one another in time when noise is added. This separation force is determined by the shape of the envelope of the interaction potential, as well as an additional Brownian ratchet effect. In systems with broken reversibility, such as third order dispersion, this ratchet effect continues to push solitons within a bound state apart. However, the force generated by the envelope of the potential is now such that it pushes the solitons towards each other, leading to a null net drift of the solitons.

Measurement of WW and WZ production in the lepton plus heavy flavor jets final state at CDF

Energy Technology Data Exchange (ETDEWEB)

Leone, Sandra [Fermilab

2016-11-16

We present the CDF measurement of the diboson WW and WZ production cross section in a final state consistent with leptonic W decay and jets originating from heavy flavor quarks, based on the full Tevatron Run II dataset. The analysis of the di–jet invariant mass spectrum allows the observation of 3.7 sigma evidence for the combined production processes of either WW or WZ bosons. The different heavy flavor decay pattern of the W and Z bosons and the analysis of the secondary–decay vertex properties allow to independently measure the WW and WZ production cross section in a hadronic final state. The measured cross sections are consistent with the standard model predictions and correspond to signal significances of 2.9 and 2.1 sigma for WW and WZ production, respectively.

On the dynamical fluctuations in the multiparticle final states of e+e- collisions

1999-01-01

The scaling property of factorial moments in the multiparticle final-states of e + e - collisions is studied in both the laboratory and the thrust-axis coordinate systems by using the Jetset generator. It turns out that in both of the two cases, the 3-dimensional lnF 2 -lnM are approximately straight lines when the phase space are divided isotropically in different directions, showing that the dynamical fluctuations in the multiparticle final-state of e + e - collisions are approximately isotropic. In the lab system, the three γ parameters obtained by fitting F 2 -M of p x , p y , p z to Ochs formula respectively are approximately equal. In the thrust system, the three γ values obtained by fitting F 2 (y)-M, F 2 (p t )-M and F 2 (φ)-M are also close to each other provided the starting point in fitting F 2 (φ)-M is chosen appropriately. All of these provide further evidence for the above assertion. The results show that the essential feature, i.e. anisotropy of approximate) isotropy, of the dynamical fluctuations in soft and hard processes can be revealed by studying the scaling property of factorial moments in the collisions. Therefore, further investigation of the scaling properties of factorial moments in various kinds of collisions processes is significant for the understanding of the essential characteristics of collision dynamics

Interference between initial and final state radiation in a QCD medium

2012-01-01

We investigate the color coherence pattern between initial and final state radiation in the presence of a QCD medium. We derive the medium-induced gluon spectrum of an "asymptotic" parton which suffers a hard scattering and subsequently crosses the medium. The angular distribution of the induced gluon spectrum is modified when one includes interference terms between the incoming and the outgoing parton at finite angle between them. The coherent, incoherent and soft limits of the medium-induced gluon spectrum are studied. In the soft limit, we provide a simple and intuitive probabilistic picture which could be of interest for Monte Carlo implementations. The configuration studied here may have phenomenological consequences in high energy nuclear collisions.

A search for the Higgsstrahlung process e+e- -> hZ is described, where the neutral Higgs boson h is assumed to decay into hadronic final states. In order to be sensitive to a broad range of models, the search is performed independent of the flavour content of the Higgs boson decay. The analysis is based on e+e- collision data collected by the OPAL detector at energies between 192 GeV and 209 GeV. The search does not reveal any significant excess over the Standard Model background prediction. Results are combined with previous searches at energies around 91 GeV and at 189 GeV. A limit is set on the product of the cross-section and the hadronic branching ration of the Higgs boson, as a function of the Higgs boson mass. Assuming the hZ coupling predicted by the Standard Model, and a Higgs boson decaying only into hadronic final states, a lower bound of 104 GeV/c2 is set on the mass at the 95% confidence level.

Search for Dark Matter direct production in the monophoton plus missing transverse momentum final state in $pp$ collisions at $\\sqrt{s}=8$ TeV with the ATLAS detector

2015-01-01

This paper presents a search for dark matter pair production in asso- ciation with an energetic photon in 20 . 3fb − 1 of pp collisions collected at √ s =8TeV by the ATLAS detector at the LHC. The final state investigated in this analysis is defined by large missing transverse momentum ( E miss T > 150 GeV) and by the pres- ence of an energetic photon ( p T > 125 GeV). Observations in data are compared to the Standard Model expectations and no significant excess is found. A model- independent limit is set on the presence of new physics in data. Data are also interpreted in the framework of effective field theories which describe the interaction between dark matter and incoming partons as a contact interaction parameterized by a set of dimensional operators.

Influence of magnetic dipole and magnetoelastic interactions on the phase states of 2D non-Heisenberg ferromagnetic with complex exchange interactions

2009-01-01

The phase states of the 2D non-Heisenberg ferromagnetic with anisotropic bilinear and biquadratic exchange interactions are investigated. The limiting cases of the system under consideration are the two-dimensional XY-model with biquadratic exchange interaction and the isotropic Heisenberg ferromagnetic. The account of the magnetic dipole interaction leads to the realization of spatially inhomogeneous quadrupolar phase. The stability regions of various phase transitions for different values of the material parameters are studied. The phase diagram is built. Besides, the temperature phase transitions are investigated. The influence of the magnetoelastic interaction on the formation of the long-range quadrupolar order is determined.

We report in this work a combined structural and state-of-the-art computational study of homopolar P-HH-P intermolecular contacts. Database surveys have shown the abundance of such surprisingly unexplored contacts, which are usually accompanied by other weak interactions in the solid state. By means of a detailed theoretical study utilizing SAPT(DFT), MP2, SCS-MP2, MP2C and CCSD(T) methods and both aug-cc-pVXZ and aug-cc-pCVXZ (X = D, T, Q, 5) basis sets as well as extrapolation to the CBS limit, we have shown that P-HH-P contacts are indeed attractive and considerably strong. SAPT(DFT) calculations have revealed the dispersive nature of the P-HH-P interaction with only minor contribution of the inductive term, whereas the first-order electrostatic term is clearly overbalanced by the first-order exchange energy. In general the computed interaction energies follow the trend: E ≈ E < E < E. Our results have also shown that the aug-cc-pVDZ (or aug-cc-pCVDZ) basis set is not yet well balanced and that the second-order dispersion energy term is the slowest converging among all SAPT(DFT) energy components. Compared to aug-cc-pVXZ basis sets, their core-correlation counterparts have a modest influence on all supermolecular interaction energies and a negligible influence on both the SAPT(DFT) interaction energy and its components.

A wide variety of new physics models gives rise to final states with third-generation quarks. This note presents new results for some of these models using 13 TeV proton-proton collisions at the CERN LHC. Direct production of third-generation supersymmetric superpartners and vector-like quarks are discussed. Also the searches looking for resonances with third-generation quarks are covered. None of the searches discussed here shows an indication of new physics and the new exclusion limits are presented.

Hyperfine interaction in the Autler-Townes effect: The formation of bright, dark, and chameleon states

This paper is devoted to clarifying the implications of hyperfine (HF) interaction in the formation of adiabatic (i.e., "laser-dressed") states and their expression in the Autler-Townes (AT) spectra. We first use the Morris-Shore model [J. R. Morris and B. W. Shore, Phys. Rev. A 27, 906 (1983), 10.1103/PhysRevA.27.906] to illustrate how bright and dark states are formed in a simple reference system where closely spaced energy levels are coupled to a single state with a strong laser field with the respective Rabi frequency ΩS. We then expand the simulations to realistic hyperfine level systems in Na atoms for a more general case when non-negligible HF interaction can be treated as a perturbation in the total system Hamiltonian. A numerical analysis of the adiabatic states that are formed by coupling of the 3 p3 /2 and 4 d5 /2 states by the strong laser field and probed by a weak laser field on the 3 s1 /2-3 p3 /2 transition yielded two important conclusions. Firstly, the perturbation introduced by the HF interaction leads to the observation of what we term "chameleon" states—states that change their appearance in the AT spectrum, behaving as bright states at small to moderate ΩS, and fading from the spectrum similarly to dark states when ΩS is much larger than the HF splitting of the 3 p3 /2 state. Secondly, excitation by the probe field from two different HF levels of the ground state allows one to address orthogonal sets of adiabatic states; this enables, with appropriate choice of ΩS and the involved quantum states, a selective excitation of otherwise unresolved hyperfine levels in excited electronic states.

Magnetic monopole interactions: shell structure of meson and baryon states

International Nuclear Information System (INIS)

Akers, D.

1986-01-01

It is suggested that a low-mass magnetic monopole of Dirac charge g = (137/2)e may be interacting with a c-quark's magnetic dipole moment to produce Zeeman splitting of meson states. The mass M 0 = 2397 MeV of the monopole is in contrast to the 10 16 -GeV monopoles of grand unification theories (GUT). It is shown that shell structure of energy E/sub n/ = M 0 + 1/4nM 0 ... exists for meson states. The presence of symmetric meson states leads to the identification of the shell structure. The possible existence of the 2397-MeV magnetic monopole is shown to quantize quark masses in agreement with calculations of quantum chromodynamics (QCD). From the shell structure of meson states, the existence of two new mesons is predicted: eta(1814 +/- 50 MeV) with I/sup G/(J/sup PC/) = 0 + (0 -+ ) and eta/sub c/ (3907 +/- 100 MeV) with J/sup PC/ = 0 -+ . The presence of shell structure for baryon states is shown

Parental and Infant Gender Factors in Parent–Infant Interaction: State-Space Dynamic Analysis

OpenAIRE

M. Angeles Cerezo; Purificación Sierra-García; Gemma Pons-Salvador; Rosa M. Trenado

2017-01-01

This study aimed to investigate the influence of parental gender on their interaction with their infants, considering, as well, the role of the infant’s gender. The State Space Grid (SSG) method, a graphical tool based on the non-linear dynamic system (NDS) approach was used to analyze the interaction, in Free-Play setting, of 52 infants, aged 6 to 10 months, divided into two groups: half of the infants interacted with their fathers and half with their mothers. There were 50% boys in each gro...

Demonstration of fuel resistant to pellet-cladding interaction. Phase I. Final report

International Nuclear Information System (INIS)

Rosenbaum, H.S.

1979-03-01

This program has as its ultimate objective the demonstration of an advanced fuel design that is resistant to the failure mechanism known as fuel pellet-cladding interaction (PCI). Two fuel concepts are being developed for possible demonstration within this program: (a) Cu-barrier fuel, and (b) Zr-liner fuel. These advanced fuels (known collectively as barrier fuels) have special fuel cladding designed to protect the Zircaloy cladding tube from the harmful effects of localized stress, and reactive fission products during reactor service. This is the final report for PHASE 1 of this program. Support tests have shown that the barrier fuel resists PCI far better than does the conventional Zircaloy-clad fuel. Power ramp tests thus far have shown good PCI resistance for Cu-barrier fuel at burnup > 12 MWd/kg-U and for Zr-liner fuel > 16 MWd/kg-U. The program calls for continued testing to still higher burnup levels in PHASE 2

The off-shell nucleon-nucleon interaction in the singlet s-state

International Nuclear Information System (INIS)

Groot, H. de

1975-01-01

This thesis studies the off-shell behaviour of the neutron-proton interaction in the singlet state. To generate phase-shift-equivalent potentials a particular type of inversion problem is solved. It requires the potential to contain a non-local, separable part which is supposed to describe part of the short-range interaction. A special solution of the general inversion problem that produces potentials consisting of two separable terms is studied. Criteria to accept or reject particular inversion solutions are discussed. Neutron-proton potentials in the 1 S 0 partial wave which form part of the input for the general inversion procedure are defined. Different local potential tails are chosen, as well as varying short-range interactions, both local and non-local. The input phase shifts are discussed including three extrapolations of the phase shifts at high energy. The half-shell transition matrix for the potentials defined is studied. Some problems introduced by the additional electromagnetic interaction in the proton-proton system is investigated. (Auth.)

Vector meson production is studied in the reaction ->K K . A clear PHI(1020) signal is seen in the K K mass distribution and a Ksup(*0)(890) signal is visible in the Ksup(+-) sup(-+) one. Both do not seem to be strongly correlated with quasi two body final states. Cross sections for the processes ->K K , ->PHI , ->Ksup(*0)Ksup(+-) sup(-+) and upper limits for the production of duction of PHIrho, PHIPHI and Ksup(*0)Ksup(*0) are given as function of the invariant mass.

Reformulation of the covering and quantizer problems as ground states of interacting particles

Science.gov (United States)

Torquato, S.

2010-11-01

It is known that the sphere-packing problem and the number-variance problem (closely related to an optimization problem in number theory) can be posed as energy minimizations associated with an infinite number of point particles in d -dimensional Euclidean space Rd interacting via certain repulsive pair potentials. We reformulate the covering and quantizer problems as the determination of the ground states of interacting particles in Rd that generally involve single-body, two-body, three-body, and higher-body interactions. This is done by linking the covering and quantizer problems to certain optimization problems involving the “void” nearest-neighbor functions that arise in the theory of random media and statistical mechanics. These reformulations, which again exemplify the deep interplay between geometry and physics, allow one now to employ theoretical and numerical optimization techniques to analyze and solve these energy minimization problems. The covering and quantizer problems have relevance in numerous applications, including wireless communication network layouts, the search of high-dimensional data parameter spaces, stereotactic radiation therapy, data compression, digital communications, meshing of space for numerical analysis, and coding and cryptography, among other examples. In the first three space dimensions, the best known solutions of the sphere-packing and number-variance problems (or their “dual” solutions) are directly related to those of the covering and quantizer problems, but such relationships may or may not exist for d≥4 , depending on the peculiarities of the dimensions involved. Our reformulation sheds light on the reasons for these similarities and differences. We also show that disordered saturated sphere packings provide relatively thin (economical) coverings and may yield thinner coverings than the best known lattice coverings in sufficiently large dimensions. In the case of the quantizer problem, we derive improved upper

Exploring Interacting Quantum Many-Body Systems by Experimentally Creating Continuous Matrix Product States in Superconducting Circuits

Directory of Open Access Journals (Sweden)

C. Eichler

2015-12-01

Full Text Available Improving the understanding of strongly correlated quantum many-body systems such as gases of interacting atoms or electrons is one of the most important challenges in modern condensed matter physics, materials research, and chemistry. Enormous progress has been made in the past decades in developing both classical and quantum approaches to calculate, simulate, and experimentally probe the properties of such systems. In this work, we use a combination of classical and quantum methods to experimentally explore the properties of an interacting quantum gas by creating experimental realizations of continuous matrix product states—a class of states that has proven extremely powerful as a variational ansatz for numerical simulations. By systematically preparing and probing these states using a circuit quantum electrodynamics system, we experimentally determine a good approximation to the ground-state wave function of the Lieb-Liniger Hamiltonian, which describes an interacting Bose gas in one dimension. Since the simulated Hamiltonian is encoded in the measurement observable rather than the controlled quantum system, this approach has the potential to apply to a variety of models including those involving multicomponent interacting fields. Our findings also hint at the possibility of experimentally exploring general properties of matrix product states and entanglement theory. The scheme presented here is applicable to a broad range of systems exploiting strong and tunable light-matter interactions.

An excited-state approach within full configuration interaction quantum Monte Carlo

International Nuclear Information System (INIS)

Blunt, N. S.; Smart, Simon D.; Booth, George H.; Alavi, Ali

2015-01-01

We present a new approach to calculate excited states with the full configuration interaction quantum Monte Carlo (FCIQMC) method. The approach uses a Gram-Schmidt procedure, instantaneously applied to the stochastically evolving distributions of walkers, to orthogonalize higher energy states against lower energy ones. It can thus be used to study several of the lowest-energy states of a system within the same symmetry. This additional step is particularly simple and computationally inexpensive, requiring only a small change to the underlying FCIQMC algorithm. No trial wave functions or partitioning of the space is needed. The approach should allow excited states to be studied for systems similar to those accessible to the ground-state method due to a comparable computational cost. As a first application, we consider the carbon dimer in basis sets up to quadruple-zeta quality and compare to existing results where available

Effect of three-body interactions on the zero-temperature equation of state of HCP solid 4He

Barnes, Ashleigh L.; Hinde, Robert J.

2017-03-01

Previous studies have pointed to the importance of three-body interactions in high density 4He solids. However the computational cost often makes it unfeasible to incorporate these interactions into the simulation of large systems. We report the implementation and evaluation of a computationally efficient perturbative treatment of three-body interactions in hexagonal close packed solid 4He utilizing the recently developed nonadditive three-body potential of Cencek et al. This study represents the first application of the Cencek three-body potential to condensed phase 4He systems. Ground state energies from quantum Monte Carlo simulations, with either fully incorporated or perturbatively treated three-body interactions, are calculated in systems with molar volumes ranging from 21.3 cm3/mol down to 2.5 cm3/mol. These energies are used to derive the zero-temperature equation of state for comparison against existing experimental and theoretical data. The equations of state derived from both perturbative and fully incorporated three-body interactions are found to be in very good agreement with one another, and reproduce the experimental pressure-volume data with significantly better accuracy than is obtained when only two-body interactions are considered. At molar volumes below approximately 4.0 cm3/mol, neither two-body nor three-body equations of state are able to accurately reproduce the experimental pressure-volume data, suggesting that below this molar volume four-body and higher many-body interactions are becoming important.

The analytical calculation of the nuclear ground state deformation of the even-even isotopes in the rare-earth region is given by utilizing the intrinsic states of the sdg interacting boson model. It is compared systematically with the reported theoretical and experimental results. It is shown that the sdg interacting boson model is a reasonable scheme for the description of even-even nuclei deformation

Starting with the indirect exchange model influenced by the Rashba and the Dresselhaus spin-orbit interactions, we derive the Dzyaloshinskii-Moriya interaction of localized spins. The strength of the Dzyaloshinskii-Moriya interaction is compared with that of the Heisenberg exchange term as a function of atomic distance. Using the calculated interaction strengths, we discuss the formation of various atomic ground states as a function of temperature and external magnetic field. By plotting the magnetic field-temperature phase diagram, we present approximate phase boundaries between the spiral, Skyrmion and ferromagnetic states of the two-dimensional weak ferromagnetic system.

The Interaction Region Group addressed the basic questions of how to collide the SLC beams, how to maximize and monitor the luminosity, and how to minimize the detector backgrounds at the interaction region. In practice, five subgroups evolved to study these questions. The final focus group provided three alternative designs to acheive the 1 to 2 micron beam spot size required by the SLC, as well as studying other problems including: eta, eta' matching from the collider arcs, the implementation of soft bends near the interaction region, beam emittance growth, and magnet tolerances in the final focus. The beam position monitor group proposed two devices, a strip line monitor, and a beamstrahlung monitor, to bring the beams into collision. The luminosity monitor group reviewed the possible QED processes that would be insensitive to weak interaction (Z 0 ) effects. The beam dumping group proposed locations for kicker and septum magnets in the final focus that would achieve a high dumping efficiency and would meet the desired beam tolerances at the Moller scattering target in the beam dump line. Working with the Polarization Group, the Moller experiment was designed into the beam dump beam line. A beam dump was proposed that would maintain radiation backgrounds (penetrating muons) at acceptible levels. The detector backgrounds group proposed soft-bend and masking configurations to shield the detector from synchrotron radiation from the hard/soft bends and from the final focus quadrupoles and evaluated the effectiveness of these designs for the three final focus optics designs. Backgrounds were also estimated from: large angle synchrotron radiation, local and distant beam-gas interactions, 2-photon interactions, and from neutrons and backscattered photons from the beamstrahlung dump

Van-der-Waals interaction of atoms in dipolar Rydberg states

An asymptotic expression for the van-der-Waals constant C 6( n) ≈ -0.03 n 12 K p ( x) is derived for the long-range interaction between two highly excited hydrogen atoms A and B in their extreme Stark states of equal principal quantum numbers n A = n B = n ≫ 1 and parabolic quantum numbers n 1(2) = n - 1, n 2(1) = m = 0 in the case of collinear orientation of the Stark-state dipolar electric moments and the interatomic axis. The cubic polynomial K 3( x) in powers of reciprocal values of the principal quantum number x = 1/ n and quadratic polynomial K 2( y) in powers of reciprocal values of the principal quantum number squared y = 1/ n 2 were determined on the basis of the standard curve fitting polynomial procedure from the calculated data for C 6( n). The transformation of attractive van-der-Waals force ( C 6 > 0) for low-energy states n < 23 into repulsive force ( C 6 < 0) for all higher-energy states of n ≥ 23, is observed from the results of numerical calculations based on the second-order perturbation theory for the operator of the long-range interaction between neutral atoms. This transformation is taken into account in the asymptotic formulas (in both cases of p = 2, 3) by polynomials K p tending to unity at n → ∞ ( K p (0) = 1). The transformation from low- n attractive van-der-Waals force into high- n repulsive force demonstrates the gradual increase of the negative contribution to C 6( n) from the lower-energy two-atomic states, of the A(B)-atom principal quantum numbers n'A(B) = n-Δ n (where Δ n = 1, 2, … is significantly smaller than n for the terms providing major contribution to the second-order series), which together with the states of n″B(A) = n+Δ n make the joint contribution proportional to n 12. So, the hydrogen-like manifold structure of the energy spectrum is responsible for the transformation of the power-11 asymptotic dependence C 6( n) ∝ n 11of the low-angular-momenta Rydberg states in many-electron atoms into the power

The 2011 dataset of the CMS experiment, consisting of an integrated luminosity of 4.98 inverse femtobarns of pp collisions at sqrt(s) = 7 TeV, enables expanded searches for direct electroweak pair production of charginos and neutralinos in supersymmetric models as well as their analogs in other models of new physics. Searches sensitive to such processes, with decays to final states that contain two or more leptons, are presented. Final states with three leptons, with a same-sign lepton pair, and with an opposite-sign lepton pair in conjunction with two jets, are examined. No excesses above the standard model expectations are observed. The results are used in conjunction with previous results on four-lepton final states to exclude a range of chargino and neutralino masses from approximately 200 to 500 GeV in the context of models that assume large branching fractions of charginos and neutralinos to leptons and vector bosons.

Interaction potentials for multiquark states from instantons and other background gauge field configurations

A simple rule is presented for calculating the contributions to the interaction potentials between constituent particles for a family of multiquark states, due to the presence of a semi-classical gauge field configuration which exists in a single SU(2) subgroup of colour SU(3). In multiquark states beyond the baryon many-body potential terms are found. The static (Wilson loop) limit is sufficient to elucidate the dependence of the potential on the colour structure of the multiquark state

Interactional dynamics of same-sex marriage legislation in the United States.

Understanding how people form opinions and make decisions is a complex phenomenon that depends on both personal practices and interactions. Recent availability of real-world data has enabled quantitative analysis of opinion formation, which illuminates phenomena that impact physical and social sciences. Public policies exemplify complex opinion formation spanning individual and population scales, and a timely example is the legalization of same-sex marriage in the United States. Here, we seek to understand how this issue captures the relationship between state-laws and Senate representatives subject to geographical and ideological factors. Using distance-based correlations, we study how physical proximity and state-government ideology may be used to extract patterns in state-law adoption and senatorial support of same-sex marriage. Results demonstrate that proximal states have similar opinion dynamics in both state-laws and senators' opinions, and states with similar state-government ideology have analogous senators' opinions. Moreover, senators' opinions drive state-laws with a time lag. Thus, change in opinion not only results from negotiations among individuals, but also reflects inherent spatial and political similarities and temporal delays. We build a social impact model of state-law adoption in light of these results, which predicts the evolution of state-laws legalizing same-sex marriage over the last three decades.

Linked-cluster formulation of electron-hole interaction kernel in real-space representation without using unoccupied states.

Electron-hole or quasiparticle representation plays a central role in describing electronic excitations in many-electron systems. For charge-neutral excitation, the electron-hole interaction kernel is the quantity of interest for calculating important excitation properties such as optical gap, optical spectra, electron-hole recombination and electron-hole binding energies. The electron-hole interaction kernel can be formally derived from the density-density correlation function using both Green's function and TDDFT formalism. The accurate determination of the electron-hole interaction kernel remains a significant challenge for precise calculations of optical properties in the GW+BSE formalism. From the TDDFT perspective, the electron-hole interaction kernel has been viewed as a path to systematic development of frequency-dependent exchange-correlation functionals. Traditional approaches, such as MBPT formalism, use unoccupied states (which are defined with respect to Fermi vacuum) to construct the electron-hole interaction kernel. However, the inclusion of unoccupied states has long been recognized as the leading computational bottleneck that limits the application of this approach for larger finite systems. In this work, an alternative derivation that avoids using unoccupied states to construct the electron-hole interaction kernel is presented. The central idea of this approach is to use explicitly correlated geminal functions for treating electron-electron correlation for both ground and excited state wave functions. Using this ansatz, it is derived using both diagrammatic and algebraic techniques that the electron-hole interaction kernel can be expressed only in terms of linked closed-loop diagrams. It is proved that the cancellation of unlinked diagrams is a consequence of linked-cluster theorem in real-space representation. The electron-hole interaction kernel derived in this work was used to calculate excitation energies in many-electron systems and results

Searches for Natural Supersymmetry in Hadronic Final States with Heavy Flavor at ATLAS

CERN Document Server

Butler, Bart

This thesis presents the hadronic-channel supersymmetric searches for direct sbottom and gluino-mediated sbottom and stop production performed on 4.71 fb$^{-1}$ of $\\sqrt{s}$ = 7 TeV data collected by the ATLAS detector at the Large Hadron Collider. These signatures are characterized by final states with multiple b-tagged jets and missing transverse energy, and the analysis strategy is chosen accordingly. Particular emphasis is placed on the utilization of the simplified models approach in signal characterization, optimization, and interpretation of results. No significant excess is observed resulting in limits set at 95% confidence level. Relative to the previous versions of the analyses, this iteration represents a several-fold increase in sensitivity to the new physics signatures considered. This is largely due to the use of three b-tag signal regions as well as signal regions based on initial state radiation.

A joint theoretical and experimental study of the excitation of the autoionizing (2s 2 ) 1 S, (2p 2 ) 1 D and (2s2p) 1 P states of helium by 100 keV proton impact is presented for the first time. The role of the three-body Coulomb interaction in the final state between the ejected electron, the scattered proton and the recoil helium ion is emphasized. Calculations have been carried out with inclusion of the three-body Coulomb interaction and within an expansion of a two-electron excitation amplitude in powers of projectile-target interaction up to the second order. A new parametrization is proposed to describe resonance profiles distorted by the Coulomb interaction in the final state (CIFS). New high-resolution (up to 68 meV) measurements of electron emission spectra made it possible to resolve the near-lying (2p 2 ) 1 D and (2s2p) 1 P resonances and reveal an evident distortion of the resonance profiles by CIFS for forward electron ejection angles below 40 o .

The net charge of final state hadrons in both the current and target fragmentation regions has been measured in a 280 GeV/c muon-proton scattering experiment. A clean kinematic separation of the two regions in the centre-of-mass rapidity is demonstrated. The dependence on chisub(Bj) of the mean net charges is found to be consistent with a large contribution of sea quarks at small chisub(Bj) and with the dominance of valence quarks at large chisub(Bj) thus giving clear confirmation of the quark-parton model. It is also shown that the leading forward hadron has a high probability of containing the struck quark. (orig.)

Search for new phenomena in diboson final states in ATLAS and CMS

CERN Document Server

Cavaliere, Viviana; The ATLAS collaboration

2015-01-01

Resonant production of two massive bosons (WW, WZ, ZZ, W/Z+gamma, W/Z+H and HH) is a smoking gun signature for physics beyond the Standard Model. Searches for diboson resonances have been performed in final states with dierent numbers of leptons and jets including fat-jets with jet substructure. The searches at the highest accessible masses employ new identification techniques to disentangle the decay products of the boson in highly boosted configurations. New resonances decaying into Higgs bosons are also considered. This talk highlights ATLAS and CMS searches for diboson resonances with LHC Run 1 data. First LHC Run-2 results will be included if available.

State Machine Framework And Its Use For Driving LHC Operational states

CERN Document Server

Misiowiec, M; Solfaroli Camilloci, M

2011-01-01

The LHC follows a complex operational cycle with 12 major phases that include equipment tests, preparation, beam injection, ramping and squeezing, finally followed by the physics phase. This cycle is modelled and enforced with a state machine, whereby each operational phase is represented by a state. On each transition, before entering the next state, a series of conditions is verified to make sure the LHC is ready to move on. The State Machine framework was developed to cater for building independent or embedded state machines. They safely drive between the states executing tasks bound to transitions and broadcast related information to interested parties. The framework encourages users to program their own actions. Simple configuration management allows the operators to define and maintain complex models themselves. An emphasis was also put on easy interaction with the remote state machine instances through standard communication protocols. On top of its core functionality, the framework offers a transparen...

Search for New Physics with Two Photons in the Final State with the ATLAS Detector

AUTHOR|(INSPIRE)INSPIRE-00441752

This thesis reports on the search for new physics in the diphoton decay channel with the proton-proton collision data collected by ATLAS at a centre-of-mass energy of $\\sqrt{s}=8$~TeV in 2012 and $\\sqrt{s}=13$~TeV in 2015 and 2016. A feasibility study of the search for a pseudoscalar $A$ decaying to a $Z$ boson and a 125~GeV Higgs boson in the context of an extended Higgs sector, namedly the two-Higgs-doublet models, is presented. The search is performed with a final state of two jets and two photons using 20.3~${\\rm fb}^{-1}$ of data at $\\sqrt{s}=8$~TeV. The expected sensitivity is found to be competitive with the analysis with a final state of two electrons or muons and two $\\tau$ leptons, but less sensitive to the other searches with the Higgs decaying to a pair of $b$-quarks. Search for high mass resonances decaying to two photons at $\\sqrt{s}=13$~TeV is also presented. The analysed dataset corresponds to an integrated luminosity of $3.2~{\\rm fb}^{-1}$ in 2015 and $12.2~{\\rm fb}^{-1}$ in 2016. Two searche...

Spin--orbit configuration-interaction study of valence and Rydberg states of LiBe

Marino, M.M.; Ermler, W.C.; Kern, C.W.; Bondybey, V.E.

1992-01-01

Ab initio spin--orbit full configuration-interaction calculations in the context of relativistic effective core potentials are reported for the weakly bound metal dimer LiBe, a three-valence-electron system. The effects of basis set on the energies of valence and Rydberg states of the cluster are discussed, as are the effects of configuration space selection on the energy of the latter states. Results at the dissociative limit are compared to the experimental atomic spectra. Potential-energy curves and spectroscopic constants are presented for the ground state and fourteen excited states, which includes the Li and Be 2p valence states, the Li 3s, 3p, 3d, and 4s Rydberg states, as well as three low-lying states of the molecular cation

Non-resonant Higgs-pair production in the b anti bb anti b final state at the LHC

Wardrope, David; Jansen, Eric; Konstantinidis, Nikos; Cooper, Ben; Falla, Rebecca; Norjoharuddeen, Nurfikri [University College London, Department of Physics and Astronomy, London (United Kingdom)

2015-05-15

We present a particle-level study of the Standard Model non-resonant Higgs-pair production process in the b anti bb anti b final state, at the Large Hadron Collider at √(s) = 14 TeV. Each Higgs boson is reconstructed from a pair of close-by jets formed with the anti-k{sub t} jet clustering algorithm, with radius parameter R = 0.4. Given the kinematic properties of the produced Higgs bosons, this Higgs reconstruction approach appears to be more suitable than the use of largeradius jets that was previously proposed in the literature.We find that the sensitivity for observing this final state can be improved significantly when the full set of uncorrelated angular and kinematic variables of the 4b system is exploited, leading to a statistical significance of 1.8 per experiment with an integrated luminosity of 3 ab{sup -1}.

Density of states and phase diagram of the antiferromagnetic spin chain with Dzyaloshinsky-Moriya interaction and spin-phonon coupling

International Nuclear Information System (INIS)

Wang Qin; Chen Hong; Zheng Hang

2007-01-01

The effects of DM interaction on the density-of-states, the dimerization and the phase diagram in the antiferromagnetic Heisenberg chain coupled with quantum phonons have been studied by a nonadiabatic analytical approach. The results show that the effect of the DM interaction is to increase the staggered antisymmetric spin exchange interaction order but to decrease the spin dimerization and their competitions result in the lattice dimerization ordering parameter to increase for large staggered DM interaction parameter β and decrease for small β. A crossover of β exists in which the dimerization ordering parameter changes non-monotonously. As the DM interaction parameter D increases, depending on the appropriate values of spin-phonon coupling, phonon frequency and β, the system undergoes phase transition from spin gapless state to gapped state or reversely and can even reenter between the two states. The relation between the phonon-staggered ordering parameter, the spin-dimer order parameter and the staggered DM interaction order parameter gives clearly their contributing weights to the lattice dimerization

Search for new physics in the monophoton final state in proton-proton collisions at sqrt(s) = 13 TeV

Energy Technology Data Exchange (ETDEWEB)

Sirunyan, Albert M; et al.

2017-06-12

A search is conducted for new physics in a final state containing a photon and missing transverse momentum in proton-proton collisions at sqrt(s) = 13 TeV. The data collected by the CMS experiment at the CERN LHC correspond to an integrated luminosity of 12.9 inverse-femtobarns. No deviations are observed relative to the predictions of the standard model. The results are interpreted as exclusion limits on the dark matter production cross sections and parameters in models containing extra spatial dimensions. Improved limits are set with respect to previous searches using the monophoton final state. In particular, the limits on the extra dimension model parameters are the most stringent to date in this channel.

Interactions between drug companies and medical students may affect evidence-based medical practice and patient safety. The aim of this study was to assess drug company-medical student interactions in a medical faculty where limited specific national or institutional regulations apply between drug companies and medical students. The objectives of the study were to determine the exposure and attitudes of final year medical students in terms of drug company-medical student and physician interactions, to identify factors affecting those attitudes and to provide data for policymakers working on the regulation of interactions between drug companies and medical students. This anonymous questionnaire-based study of 154 medical final year medical students at the Karadeniz Technical University Medical Faculty, Trabzon, Turkey, in April and May 2015 attracted a response rate of 92.2% (n/N, 154/164). Exposure to interaction with a pharmaceutical representative was reported by 90.3% (139/154) of students, and 68.8% (106/154) reported experiencing such interaction alongside a resident. In addition, 83.7% (128/153) of students reported an interaction during internship. Furthermore, 69.9% (107/153) of students agreed that interactions influence physicians' prescription preferences, while 33.1% (51/154) thought that a medical student should never accept a gift from a drug company and 24.7% (38/154) agreed with the proposition that "drug companies should not hold activities in medical faculties". Students with rational prescription training expressed greater agreement with the statement "I am skeptical concerning the information provided by drug companies during interactions" than those who had not received such training, and this finding was supported by logistic regression [O.R.(C.I), p -3.7(1.2-11.5), p = 0.022].

Host-guest interaction of styrene and ethylbenzene in MIL-53 studied by solid-state NMR.

Science.gov (United States)

Li, Shenhui; Li, Jing; Tang, Jing; Deng, Feng

Solid-state NMR was utilized to explore the host-guest interaction between adsorbate and adsorbent at atomic level to understand the separation mechanism of styrene (St) and ethylbenzene (EB) in MIL-53(Al). 13 C- 27 Al double-resonance NMR experiments revealed that the host-guest interaction between St and MIL-53 was much stronger than that of EB adsorption. In addition, 13 C DIPSHIFT experiments suggested that the adsorbed St was less mobile than EB confined inside the MIL-53 pore. Furthermore, the host-guest interaction model between St, EB and MIL-53 was established on the basis of the spatial proximities information extracted from 2D 1 H- 1 H homo-nuclear correlation NMR experiments. According to the experimental observation from solid-state NMR, it was found that the presence of π-π interaction between St and MIL-53 resulted in the stronger host-guest interaction and less mobility of St. This work provides direct experimental evidence for understanding the separation mechanism of St and EB using MIL-53 as an adsorbent.

Macroscopic nonclassical-state preparation via postselection

Montenegro, Víctor; Coto, Raúl; Eremeev, Vitalie; Orszag, Miguel

2017-11-01

Macroscopic quantum superposition states are fundamental to test the classical-quantum boundary and present suitable candidates for quantum technologies. Although the preparation of such states has already been realized, the existing setups commonly consider external driving and resonant interactions, predominantly by considering Jaynes-Cummings-like and beam-splitter-like interactions, as well as the nonlinear radiation pressure interaction in cavity optomechanics. In contrast to previous works on the matter, we propose a feasible probabilistic scheme to generate a macroscopic mechanical qubit, as well as phononic Schrödinger's cat states with no need of any energy exchange with the macroscopic mechanical oscillator. Essentially, we investigate an open dispersive spin-mechanical system in the absence of any external driving under nonideal conditions, such as the detrimental effects due to the oscillator and spin energy losses in a thermal bath at nonzero temperature. In our work, we show that the procedure to generate the mechanical qubit state is solely based on spin postselection in the weak to moderate coupling regime. Finally, we demonstrate that the mechanical superposition is related to the amplification of the mean values of the mechanical quadratures as they maximize the quantum coherence.

Unique dispersion states of nanoparticles in polymeric matrices have the potential to create composites with enhanced mechanical, thermal, and electrical properties. The present work aims to determine the state of dispersion from the melt-state rheological behavior of nanocomposites based on carbon nanotube and graphene nanoribbon (GNR) nanomaterials. GNRs were synthesized from nitrogen-doped carbon nanotubes via a chemical route using potassium permanganate and some second acids. High-density polyethylene (HDPE)/GNR nanocomposite samples were then prepared through a solution mixing procedure. Different nanocomposite dispersion states were achieved using different GNR synthesis methods providing different surface chemistry, interparticle interactions, and internal compartments. Prolonged relaxation of flow induced molecular orientation was observed due to the presence of both carbon nanotubes and GNRs. Based on the results of this work, due to relatively weak interactions between the polymer and the nanofillers, it is expected that short-range interactions between nanofillers play the key role in the final dispersion state.

The heavy quark content of gauge boson events is of great interest to studies of QCD. These events probe the gluon and heavy-quark parton distribution functions of the proton, and also provide a measurement of the rate of final state gluon splitting to heavy flavor. In addition, gauge boson plus heavy quark events are representative of backgrounds to Higgs, single top, and supersymmetric particle searches. Recent work with the CDF II detector at the Fermilab Tevatron has measured the cross-section of several gauge boson plus heavy flavor production processes, including the first Tevatron observation of specific charm process p{p bar} → W +c. Results are found to be in agreement with NLO predictions that include an enhanced rate of g → {cc bar}/bb splitting. Lastly, a new analysis promises to probe a lower pT (c) region than has been previously explored, by fully reconstructing D* → D0(Kπ)π decays in the full CDF dataset (9.7 fb-1).

Thermodynamical interactions: subtleties of heat and work concepts

This paper focuses on the determination of the final equilibrium state when two ideal gases, isolated from the exterior and starting from preset initial conditions, interact with each other through a piston. Depending on the piston properties, different processes take place and also different sets of equilibrium conditions must be satisfied. Three cases are analysed, namely, when (case 1) the piston is a heat conductor and free to move, (case 2) the piston allows heat conduction but its position is fixed, and (case 3) the piston is free to move but it is adiabatic (so no heat can be exchanged). Cases 1 and 2 have straightforward solutions, but it is shown that case 3 leads to an undeterminable final state. Even though this last situation seems to be strange and difficult, mechanical and thermodynamical analyses are performed. It is shown that the determinability of the final state depends on whether friction is considered or not. Carried out numerically, both analyses provide consistent results and not only do they enable an interesting and useful discussion regarding the concepts of energy, heat, work and entropy, but they also reinforce some ideas which were recently published

We apply Non-orthogonal Configuration Interaction (NOCI) to molecular systems where multielectron excitations, in this case double excitations, play a substantial role: the linear polyenes and β-carotene. We demonstrate that NOCI when applied to systems with extended conjugation, provides a qualitatively correct wavefunction at a fraction of the cost of many other multireference treatments. We also present a new extension to this method allowing for purification of higher-order spin states by utilizing Generalized Hartree-Fock Slater determinants and the details for computing 〈S{sup 2}〉 for the ground and excited states.

2015-08-01

Full Text Available Abstract The form factor of a separable interaction between a pair of particles is an important input in a three body calculation for a transfer reaction. The three body equations of Alt Grassberger and Sandhas have been solved for a system of three particles viz.p n and 16Oand p n and 40Ca when coulomb interaction is included between the particle pairs. The input in this calculation i.e. the two body t-matrices representing the interaction between the pairs of particles is taken to be of a separable form conforming to the bound state of the pair. The form factors of the total interaction between the particle pairs are constructed using the prescription of Ueta and Bund.

The Notch signaling pathway consists of multiple types of receptors and ligands, whose interactions can be tuned by Fringe glycosyltransferases. A major challenge is to determine how these components control the specificity and directionality of Notch signaling in developmental contexts. Here, we analyzed same-cell (cis) Notch-ligand interactions for Notch1, Dll1, and Jag1, and their dependence on Fringe protein expression in mammalian cells. We found that Dll1 and Jag1 can cis-inhibit Notch1, and Fringe proteins modulate these interactions in a way that parallels their effects on trans interactions. Fringe similarly modulated Notch-ligand cis interactions during Drosophila development. Based on these and previously identified interactions, we show how the design of the Notch signaling pathway leads to a restricted repertoire of signaling states that promote heterotypic signaling between distinct cell types, providing insight into the design principles of the Notch signaling system, and the specific developmental process of Drosophila dorsal-ventral boundary formation.

Role of four-fermion interaction and impurity in the states of two-dimensional semi-Dirac materials.

Science.gov (United States)

Wang, Jing

2018-03-28

We study the effects of four-fermion interaction and impurity on the low-energy states of 2D semi-Dirac materials by virtue of the unbiased renormalization group approach. The coupled flow equations that govern the energy-dependent evolutions of all correlated interaction parameters are derived after taking into account one-loop corrections from the interplay between four-fermion interaction and impurity. Whether and how four-fermion interaction and impurity influence the low-energy properties of 2D semi-Dirac materials are discreetly explored and addressed attentively. After carrying out the standard renormalization group analysis, we find that both trivial insulating and nontrivial semimetal states are qualitatively stable against all four kinds of four-fermion interactions. However, while switching on both four-fermion interaction and impurity, certain insulator-semimetal phase transitions and the distance of Dirac nodal points can be respectively induced and modified due to their strong interplay and intimate competition. Moreover, several non-Fermi liquid behaviors that deviate from the conventional Fermi liquids are exhibited at the lowest-energy limit.

We measure the mass of the top quark in lepton$+$jets final states using the full sample of $p\\bar{p}$ collision data collected by the D0 experiment in Run II of the Fermilab Tevatron Collider at $\\sqrt s=1.96 $TeV, corresponding to $9.7 {\\rm fb}^{-1}$ of integrated luminosity. We use a matrix element technique that calculates the probabilities for each event to result from $t\\bar t$ production or background. The overall jet energy scale is constrained in situ by the mass of the $W$ boson. We measure $m_t=174.98\\pm0.76$ GeV. This constitutes the most precise single measurement of the top-quark mass.

Ishikawa, Souichi

2018-01-01

Spin-isospin excitation of the {}^3He nucleus by a proton-induced charge exchange reaction, {}^3He(p,n)ppp, at forward neutron scattering angle is studied in a plane wave impulse approximation (PWIA). In PWIA, cross sections of the reaction are written in terms of proton-neutron scattering amplitudes and response functions of the transition from {}3He to the three-proton state by spin-isospin transition operators. The response functions are calculated with realistic nucleon-nucleon potential models using a Faddeev three-body method. Calculated cross sections agree with available experimental data in substance. Possible effects arising from the uncertainty of proton-neutron amplitudes and three-nucleon interactions in the three-proton system are examined.

Interactions between drug companies and medical students may affect evidence-based medical practice and patient safety. The aim of this study was to assess drug company–medical student interactions in a medical faculty where limited specific national or institutional regulations apply between drug companies and medical students. The objectives of the study were to determine the exposure and attitudes of final year medical students in terms of drug company–medical student and physician interactions, to identify factors affecting those attitudes and to provide data for policymakers working on the regulation of interactions between drug companies and medical students. This anonymous questionnaire-based study of 154 medical final year medical students at the Karadeniz Technical University Medical Faculty, Trabzon, Turkey, in April and May 2015 attracted a response rate of 92.2% (n/N, 154/164). Exposure to interaction with a pharmaceutical representative was reported by 90.3% (139/154) of students, and 68.8% (106/154) reported experiencing such interaction alongside a resident. In addition, 83.7% (128/153) of students reported an interaction during internship. Furthermore, 69.9% (107/153) of students agreed that interactions influence physicians’ prescription preferences, while 33.1% (51/154) thought that a medical student should never accept a gift from a drug company and 24.7% (38/154) agreed with the proposition that “drug companies should not hold activities in medical faculties”. Students with rational prescription training expressed greater agreement with the statement “I am skeptical concerning the information provided by drug companies during interactions” than those who had not received such training, and this finding was supported by logistic regression [O.R.(C.I), p -3.7(1.2–11.5), p = 0.022]. Acceptance of advertisement brochures was found to significantly reduce the level of agreement with the proposition that “A physician should not

Preliminary results from a search for the production of an associated lightest chargino, W 1 , and second lightest neutralino, Z 2 , pair with the D0 detector at Fermilab's pp collider with √s = 1.8 TeV are presented.

State-dependent classical potentials

International Nuclear Information System (INIS)

D'Amico, M.

2001-01-01

As alternative treatment to the potential operators of standard quantum mechanics is presented. The method is derived from Bohm's mechanics. The operator scalar (V) and vector (A) potential functions are replaced by a quantum potential. It is argued that the classical potential is a special limiting case of a more general quantum potential. The theory is illustrated by deriving an equivalent single-particle equation for the i-th particle of an n-body Bohmian system. The resulting effective state-dependent potential holds the interaction between the single-particle self-wave ψ s and the environment wave ψ e of the n - 1 remaining particles. The effective state-dependent potential is offered as a resolution to the Aharonov-Bohm effect where the phase difference is shown to result from the presence of ψ e . Finally, the interaction between ψ s and ψ e is illustrated graphically

Point interactions in two- and three-dimensional Riemannian manifolds

Erman, Fatih; Turgut, O Teoman

2010-01-01

We present a non-perturbative renormalization of the bound state problem of n bosons interacting with finitely many Dirac-delta interactions on two- and three-dimensional Riemannian manifolds using the heat kernel. We formulate the problem in terms of a new operator called the principal or characteristic operator Φ(E). In order to investigate the problem in more detail, we then restrict the problem to one particle sector. The lower bound of the ground state energy is found for a general class of manifolds, e.g. for compact and Cartan-Hadamard manifolds. The estimate of the bound state energies in the tunneling regime is calculated by perturbation theory. Non-degeneracy and uniqueness of the ground state is proven by the Perron-Frobenius theorem. Moreover, the pointwise bounds on the wave function is given and all these results are consistent with the one given in standard quantum mechanics. Renormalization procedure does not lead to any radical change in these cases. Finally, renormalization group equations are derived and the β function is exactly calculated. This work is a natural continuation of our previous work based on a novel approach to the renormalization of point interactions, developed by Rajeev.

The possible Bπ molecular state and its radiative decay

Recently, several exotic bosons have been confirmed as multi-quark states. However, there are violent disputes about their inner structures, namely if they are molecular states or tetraquarks, or even mixtures of the two structures. It would be interesting to search experimentally for non-strange four-quark states with open charm or bottom which are lighter than Λ{sub c} or Λ{sub b}. Reasonable arguments indicate that they are good candidates of pure molecular states Dπ or Bπ because pions are the lightest boson. Both Bπ and Dπ bound states do not decay via the strong interaction. The Bπ molecule may decay into B* by radiating a photon, whereas the Dπ molecule can only decay via weak interaction. In this paper we explore the mass spectra of the Bπ molecular states by solving the corresponding instantaneous B-S equation. Then the rate of radiative decay vertical stroke (3)/(2), (1)/(2) right angle → B*γ is calculated and our numerical results indicate that the processes can be measured by the future experiment. We also briefly discuss the Dπ case. Due to the constraint of the final state phase space it can only decay via weak interaction. (orig.)

Self-interaction corrected density functional calculations of molecular Rydberg states

International Nuclear Information System (INIS)

Gudmundsdóttir, Hildur; Zhang, Yao; Weber, Peter M.; Jónsson, Hannes

2013-01-01

A method is presented for calculating the wave function and energy of Rydberg excited states of molecules. A good estimate of the Rydberg state orbital is obtained using ground state density functional theory including Perdew-Zunger self-interaction correction and an optimized effective potential. The total energy of the excited molecule is obtained using the Delta Self-Consistent Field method where an electron is removed from the highest occupied orbital and placed in the Rydberg orbital. Results are presented for the first few Rydberg states of NH 3 , H 2 O, H 2 CO, C 2 H 4 , and N(CH 3 ) 3 . The mean absolute error in the energy of the 33 molecular Rydberg states presented here is 0.18 eV. The orbitals are represented on a real space grid, avoiding the dependence on diffuse atomic basis sets. As in standard density functional theory calculations, the computational effort scales as NM 2 where N is the number of orbitals and M is the number of grid points included in the calculation. Due to the slow scaling of the computational effort with system size and the high level of parallelism in the real space grid approach, the method presented here makes it possible to estimate Rydberg electron binding energy in large molecules

Smart sensor: a platform for an interactive human physiological state recognition study

2013-03-01

Full Text Available This paper describes a concept of making interactive human state recognition systems based on smart sensor design. The token measures on proper ADC signal processing had significantly lowered the interference level. A more reliable way of measuring human skin temperature was offered by using Maxim DS18B20 digital thermometers. They introduced a more sensible response to temperature changes compared to previously used analog LM35 thermometers. An adaptive HR measuring algorithm was introduced to suppress incorrect ECG signal readings caused by human muscular activities. User friendly interactive interface for touch sensitive GLCD screen was developed to present real time physiological data readings both in numerals and graphics. User was granted an ability to dynamically customize data processing methods according to his needs. Specific procedures were developed to simplify physiological state recording for further analysis. The introduced physiological data sampling and preprocessing platform was optimized to be compatible with “ATmega Oscilloscope” PC data collecting and visualizing software.

Charmless Hadronic B Decays into Vector, Axial Vector and Tensor Final States at BaBar

International Nuclear Information System (INIS)

Gandini, Paolo

2012-01-01

We present experimental measurements of branching fraction and longitudinal polarization fraction in charmless hadronic B decays into vector, axial vector and tensor final states with the final dataset of BABAR. Measurements of such kind of decays are a powerful tool both to test the Standard Model and search possible sources of new physics. In this document we present a short review of the last experimental results at BABAR concerning charmless quasi two-body decays in final states containing particles with spin 1 or spin 2 and different parities. This kind of decays has received considerable theoretical interest in the last few years and this particular attention has led to interesting experimental results at the current b-factories. In fact, the study of longitudinal polarization fraction f L in charmless B decays to vector vector (VV), vector axial-vector (VA) and axial-vector axial-vector (AA) mesons provides information on the underlying helicity structure of the decay mechanism. Naive helicity conservation arguments predict a dominant longitudinal polarization fraction f L ∼ 1 for both tree and penguin dominated decays and this pattern seems to be confirmed by tree-dominated B → ρρ and B + → (Omega)ρ + decays. Other penguin dominated decays, instead, show a different behavior: the measured value of f L ∼ 0.5 in B → φK* decays is in contrast with naive Standard Model (SM) calculations. Several solutions have been proposed such as the introduction of non-factorizable terms and penguin-annihilation amplitudes, while other explanations invoke new physics. New modes have been investigated to shed more light on the problem.

Exponentially Enhanced Light-Matter Interaction, Cooperativities, and Steady-State Entanglement Using Parametric Amplification

2018-03-01

We propose an experimentally feasible method for enhancing the atom-field coupling as well as the ratio between this coupling and dissipation (i.e., cooperativity) in an optical cavity. It exploits optical parametric amplification to exponentially enhance the atom-cavity interaction and, hence, the cooperativity of the system, with the squeezing-induced noise being completely eliminated. Consequently, the atom-cavity system can be driven from the weak-coupling regime to the strong-coupling regime for modest squeezing parameters, and even can achieve an effective cooperativity much larger than 100. Based on this, we further demonstrate the generation of steady-state nearly maximal quantum entanglement. The resulting entanglement infidelity (which quantifies the deviation of the actual state from a maximally entangled state) is exponentially smaller than the lower bound on the infidelities obtained in other dissipative entanglement preparations without applying squeezing. In principle, we can make an arbitrarily small infidelity. Our generic method for enhancing atom-cavity interaction and cooperativities can be implemented in a wide range of physical systems, and it can provide diverse applications for quantum information processing.

We calculate the cross-sections for the radiative formation of bound states by dark matter whose interactions are described in the non-relativistic regime by a Yukawa potential. These cross-sections are important for cosmological and phenomenological studies of dark matter with long-range interactions, residing in a hidden sector, as well as for TeV-scale WIMP dark matter. We provide the leading-order contributions to the cross-sections for the dominant capture processes occurring via emission of a vector or a scalar boson. We offer a detailed inspection of their features, including their velocity dependence within and outside the Coulomb regime, and their resonance structure. For pairs of annihilating particles, we compare bound-state formation with annihilation.

Excellent jets reconstruction efficiencies and mass resolution capability of the di-jet system are crucial aspects of the detector performance for the signal observability in these channels. Full simulation and reconstruction of the four representative channels with b-jets in final states is discussed: WH, t(anti)tH with H → b(anti)b and A → Zh, H → hh with h → b(anti)b. These channels are used as benchmark ones to study the different complexity of events, level of combinatorial background from signal itself and universality of the algorithms used for jets reconstruction and energy calibration at the wide range of energy/mass scales. Equivalently important aspect of this study is to verify applicability of the fast detector simulation, based on parametrisation of main features of the detector, for studying signal and background rates for the above channels. For that reason the detailed comparisons of the expected efficiencies and acceptances in full (based on GEANT 3) and fast simulations are shown at the different stages of the selection procedures. In general good agreement is found between results obtained in both approaches. (author)

Search for Microscopic Black Holes in Multijet Final States with the ATLAS Detector using 8 TeV Proton-Proton Collisions at the Large Hadron Collider

Saddique, Asif

Microscopic black holes are expected to produce a high multiplicity of Standard Model (SM) particles having large transverse momenta in the final state. In this thesis, a search for microscopic black holes in multijet final states with the ATLAS 2012 data using 8 TeV centre of mass energy of proton-proton collisions at the Large Hadron Collider is performed in a data sample corresponding to an integrated luminosity of $20.3$ fb$^{-1}$. The search is simplified to multijet final states because most of the expected SM particles produced from black hole decay would lead to hadronic jets. The data events with high-transverse momenta have been analysed for different exclusive jet multiplicities, i.e. $2,3,...,7$, and inclusive jet multiplicities, i.e. $\\geq 3,4,...,7$. In this multijet analysis, Quantum Chromodynamics (QCD) multijet production is the main background. For all the multijet final states, the data distributions for the sum of jet transverse momenta ($H_{T}=\\sum p_{T}$) in an event have been observed ...

CMS has searched for new physics in the fully hadronic final state. Because of the large branching fraction into quarks compared to charged leptons, analyses in this channel have generally large acceptances and therefore competitive sensitivities. The result of three independent and complementary analysis strategies are presented. The ''Razor" analysis using 36 pb$^{-1}$ of luminosity and the $\\alpha_T$ analysis, updated with 1.1 fb$^{-1}$, make use of different event-shape variables to supress the background. The third analysis searches in the missing transverse energy tail for an excess in 36 pb$^{-1}$ of data above the standard model background expectation modeled by data-driven methods. In the absence of any sign for new physics in the data exclusion contours in the constrained MSSM are derived and cross-section limits are interpreted in the framework of simplified models.

Search for excited states of light and heavy flavor quarks in the $\\gamma$+jet final state in proton-proton collisions at $\\sqrt{s} =$ 13 TeV

A search is presented for excited quarks of light and heavy flavor that decay to $\\gamma$+jet final states. The analysis is based on data corresponding to an integrated luminosity of 35.9 fb$^{-1}$ collected by the CMS experiment in proton-proton collisions at $\\sqrt{s}=$ 13 TeV at the LHC. A signal would appear as a resonant contribution to the invariant mass spectrum of the $\\gamma$+jet system, above the background expected from standard model processes. No resonant excess is found, and upper limits are set on the product of the excited quark cross section and its branching fraction as a function of its mass. These are the most stringent limits to date in the $\\gamma$+jet final state, and exclude excited light quarks with masses below 5.5 TeV and excited b quarks with masses below 1.8 TeV, assuming standard model couplings.

Search for new physics in final states with a high energy electron and large missing transverse energy

The most successful and comprehensive theory describing the microcosm is the Standard Model of particle physics (SM). It comprises all known elementary particles and describes in high precision the basic processes of three of the four fundamental interactions. But still, not all experimental observations and theoretical challenges are covered. Many models exist that take the SM as a good approximation of natural phenomena in already discovered energy regions, but extend it in various ways. The Large Hadron Collider (LHC) provides the opportunity to look into these high energy regions using proton-proton collisions at significantly higher center-of-mass energies than previous experiments. This dissertation searches for physics beyond the SM especially in final states with one highly energetic electron (respectively positron) and large missing transverse energy. With the data set recorded in 2012 by the ATLAS detector, a large multi-purpose detector making use of the LHC, the spectrum of the related combined transverse mass can be measured up to the TeV scale. To find any evidence to the existence of new physics beyond the SM, it was searched for significant deviations between the observed data and the expectations due to SM processes. Unfortunately, no significant excess could be observed and exclusion limits in the context of three different new physics scenarios are provided. Besides a so-called Sequential Standard Model (SSM) predicting additional vector gauge bosons, also the possible existence of (charged) chiral bosons is analyzed. Also inferences about dark matter candidates called ''weakly interacting massive particles (WIMP)'' are drawn. With the aid of a Bayesian ansatz, the observed (expected) exclusion limit on the boson pole mass is set to 3.13 TeV(3.13 TeV) for a SSM W' boson and to 3.08 TeV(3.08 TeV) for charged chiral W{sup *} bosons (at 95% C.L.).

A search is conducted for new physics in a final state containing a photon and missing transverse momentum in proton-proton collisions at $ \\sqrt{s} = $ 13 TeV. The data collected by the CMS experiment at the CERN LHC correspond to an integrated luminosity of 12.9 fb$^{-1}$. No deviations are observed relative to the predictions of the standard model. The results are interpreted as exclusion limits on the dark matter production cross sections and parameters in models containing extra spatial dimensions. Improved limits are set with respect to previous searches using the monophoton final state. In particular, the limits on the extra dimension model parameters are the most stringent to date in this channel.

Applications in soil-structure interactions. Final report, June 1979

International Nuclear Information System (INIS)

Jhaveri, D.P.

1979-01-01

Complex phenomenon of soil-structure interaction was assessed. Relationships between the characteristics of the earthquake ground motions, the local soil and geologic conditions, and the response of the structures to the ground motions were studied. (I) The use of the explicit finite-difference method to study linear elastic soil-structure interaction is described. A linear two-dimensional study of different conditions that influence the dynamic compliance and scattering properties of foundations is presented. (II) The FLUSH computer code was used to compute the soil-structure interaction during SIMQUAKE 1B, an experimental underground blast excitation of a 1/12-scale model of a nuclear containment structure. Evaluation was performed using transient excitation, applied to a finite-difference grid. Dynamic foundation properties were studied. Results indicate that the orientation and location of the source relative to the site and the wave environment at the site may be important parameters to be considered. Differences between the computed and experimental recorded responses are indicated, and reasons for the discrepancy are suggested. (III) A case study that examined structural and ground response data tabulated and catalogued from tests at the Nevada Test Site for its applicability to the soil-structure interaction questions of interest is presented. Description, methods, and evaluation of data on soil-structure interaction from forced vibration tests are presented. A two-dimensional finite-difference grid representing a relatively rigid structure resting on uniform ground was analyzed and monitored. Fourier spectra of monitored time histories were also evaluated and are presented. Results show clear evidence of soil-structure interaction and significant agreement with theory. 128 figures, 18 tables

Excitation of autoionizing states of helium by 100 keV proton impact: theory and experiment

Energy Technology Data Exchange (ETDEWEB)

A joint theoretical and experimental study of the excitation of the autoionizing (2s{sup 2}){sup 1}S, (2p{sup 2}){sup 1}D and (2s2p){sup 1}P states of helium by 100 keV proton impact is presented for the first time. The role of the three-body Coulomb interaction in the final state between the ejected electron, the scattered proton and the recoil helium ion is emphasized. Calculations have been carried out with inclusion of the three-body Coulomb interaction and within an expansion of a two-electron excitation amplitude in powers of projectile-target interaction up to the second order. A new parametrization is proposed to describe resonance profiles distorted by the Coulomb interaction in the final state (CIFS). New high-resolution (up to 68 meV) measurements of electron emission spectra made it possible to resolve the near-lying (2p{sup 2}){sup 1}D and (2s2p){sup 1}P resonances and reveal an evident distortion of the resonance profiles by CIFS for forward electron ejection angles below 40{sup o}.

Scaling in inelastic proton-proton interactions at storage ring energies of 23-63 GeV

International Nuclear Information System (INIS)

Thome, W.

1980-02-01

In this paper inelastic proton-proton interactions are studied with low transversal momenta ( approx. equal to 350 MeV/c) of the final state hadrons. The reaction products from p-p collisions have been detected for the first time visually, using two large streamer chambers which enclose one interaction region of the CERN storage rings almost completely.

Thermal solid-state Z/E isomerization of 2-alkylidene-4-oxothiazolidines: effects of non-covalent interactions

Directory of Open Access Journals (Sweden)

ZDRAVKO DŽAMBASKI

2011-03-01

Full Text Available Configurational isomerization of stereo-defined 5-substituted and unsubstituted 2-alkylidene-4-oxothiazolidines (1 in the solid state, giving the Z/E mixtures in various ratios, was investigated by 1H-NMR spectroscopy, X-ray powder crystallography and differential scanning calorimetry (DSC. The Z/E composition can be rationalized in terms of non-covalent interactions, involving intermolecular and intramolecular hydrogen bonding and directional non-bonded 1,5-type S×××O interactions. X-Ray powder crystallography, using selected crystalline (Z-4-oxothiazolidine substrates, revealed transformation to the amorphous state during the irreversible Z®E process. A correlation between previous results on the Z/E isomerization in solution and now in the solid state was established.

Higgs boson measurements and extended scalar sector searches in bosonic final states

CERN Document Server

Zenz, Seth

2017-01-01

Searches for additional Higgs-like bosons in the H to WW and H to ZZ decay channels are reported, for boson masses in the range 145 $< m_H <$ 1000 GeV. The results are based upon proton-proton collision data samples at $\\sqrt{s}$ = 8 and 13 TeV, recorded by the CMS experiment at the LHC. Several final states of the WW and ZZ decays are analyzed. Upper limits for the search for a heavy BSM resonance and the combined upper limits at 95$\\%$ confidence level on the products of the cross section and branching fraction. These data are also used to constrain the SM Higgs boson total decay width, finding observed and expected limits at the 95$\\%$ confidence level (CL).

Search for Supersymmetry in the Dilepton Final State with Taus at CDF Run II

International Nuclear Information System (INIS)

Forrest, Robert David

2011-01-01

This thesis presents the results a search for chargino and neutralino supersymmetric particles yielding same signed dilepton final states including one hadronically decaying tau lepton using 6.0 fb -1 of data collected by the the CDF II detector. This signature is important in SUSY models where, at high tan β, the branching ratio of charginos and neutralinos to tau leptons becomes dominant. We study event acceptance, lepton identification cuts, and efficiencies. We set limits on the production cross section as a function of SUSY particle mass for certain generic models.

This thesis presents the results a search for chargino and neutralino supersymmetric particles yielding same signed dilepton final states including one hadronically decaying tau lepton using 6.0 fb^-1 of data collected by the the CDF II detector. This signature is important in SUSY models where, at high tan β, the branching ratio of charginos and neutralinos to tau leptons becomes dominant. We study event acceptance, lepton identification cuts, and efficiencies. We set limits on the production cross section as a function of SUSY particle mass for certain generic models.

Topological Edge-State Manifestation of Interacting 2D Condensed Boson-Lattice Systems in a Harmonic Trap

Science.gov (United States)

Galilo, Bogdan; Lee, Derek K. K.; Barnett, Ryan

2017-11-01

In this Letter, it is shown that interactions can facilitate the emergence of topological edge states of quantum-degenerate bosonic systems in the presence of a harmonic potential. This effect is demonstrated with the concrete model of a hexagonal lattice populated by spin-one bosons under a synthetic gauge field. In fermionic or noninteracting systems, the presence of a harmonic trap can obscure the observation of edge states. For our system with weakly interacting bosons in the Thomas-Fermi regime, we can clearly see a topological band structure with a band gap traversed by edge states. We also find that the number of edge states crossing the gap is increased in the presence of a harmonic trap, and the edge modes experience an energy shift while traversing the first Brillouin zone which is related to the topological properties of the system. We find an analytical expression for the edge-state energies and our comparison with numerical computation shows excellent agreement.

Measurement of open beauty production at HERA in the D*μ final state

International Nuclear Information System (INIS)

Chekanov, S.; Derrick, M.; Magill, S.

2006-09-01

The production of beauty quarks with a D *± and a muon in the final state has been measured with the ZEUS detector at HERA using an integrated luminosity of 114 pb -1 . Low transverse-momentum thresholds for the muon and D * meson allow a measurement of beauty production closer to the production threshold than previous measurements. The beauty signal was extracted using the charge correlations and angular distributions of the muon with respect to the D * meson. Cross sections for photoproduction and deep inelastic scattering are somewhat higher than, but compatible with, next-to-leading-order QCD predictions, and compatible with other measurements. (orig.)

Folding of polymer chains with short-range binormal interactions

International Nuclear Information System (INIS)

Craig, A; Terentjev, E M

2006-01-01

We study the structure of chains which have anisotropic short-range contact interactions that depend on the alignment of the binormal vectors of chain segments. This represents a crude model of hydrogen bonding or 'stacking' interactions out of the plane of curvature. The polymers are treated as ribbon-like semi-flexible chains, where the plane of the ribbon is determined by the local binormal. We show that with dipole-dipole interactions between the binormals of contacting chain segments, mean-field theory predicts a first-order transition to a binormally aligned state. We describe the onset of this transition as a function of the temperature-dependent parameters that govern the chain stiffness and the strength of the binormal interaction, as well as the binormal alignment's coupling to chain collapse. We also examine a metastable state governing the folding kinetics. Finally, we discuss the possible mesoscopic structure of the aligned phase, and application of our model to secondary structure motifs like β-sheets and α-helices, as well as composite structures like β-(amyloid) fibrils

Supersymmetry Searches in Dilepton Final States with the ATLAS Experiment

CERN Document Server

Lungwitz, Matthias

One of the main goals of the ATLAS experiment at the Large Hadr on Collider (LHC) at CERN in Geneva is the search for new physics beyond the Standa rd Model. In 2011, proton- proton collisions were performed at the LHC at a center of mas s energy of 7 TeV and an in- tegrated luminosity of 4 . 7 fb − 1 was recorded. This dataset can be tested for one of the most promising theories beyond limits achieved thus far: supers ymmetry. Final states in supersym- metry events at the LHC contain highly energetic jets and siz eable missing transverse energy. The additional requirement of events with highly energetic leptons simplifies the control of the backgrounds. This work presents results of a search for supe rsymmetry in the inclusive dilepton channel. Special emphasis is put on the search within the Gau ge-Mediated Symmetry Breaking (GMSB) scenario in which the supersymmetry breaking is medi ated via gauge fields. Statis- tically independent Control Regions for the dominant Stand ard Model backgrounds as well as ...

Rabi Oscillations between Ground and Rydberg States with Dipole-Dipole Atomic Interactions

We demonstrate Rabi oscillations of small numbers of 87 Rb atoms between ground and Rydberg states with n≤43. Coherent population oscillations are observed for single atoms, while the presence of two or more atoms decoheres the oscillations. We show that these observations are consistent with van der Waals interactions of Rydberg atoms

Search for new physics in $t\\bar{t}$ final states with additional heavy-flavor jets with the ATLAS detector

CERN Document Server

AUTHOR|(SzGeCERN)702756; Juste Rozas, Aurelio

2016-01-01

This dissertation presents searches in $t\\bar{t}$ final states with additional heavy-flavor jets using $20.3\\ {fb^{-1}}$ of $pp$ collision data at $\\sqrt{s} = 8\\ TeV$, recorded with the ATLAS experiment at the LHC. Exploiting this final state, three analyses are presented that address the instability of the Higgs boson mass from different perspectives. The main challenge for the presented analyses lies in the precise modeling of the background, in particular $t\\bar{t}+b\\bar{b}$. Since no measurements have been performed yet on the $t\\bar{t}$ production with additional heavy-flavor jets, the analyses have to rely on Monte Carlo (MC) simulation for the background. Recent developments in MC simulation have improved the description of the background, and a great effort is invested in porting the state-of-the-art predictions into the analyses. The systematic uncertainties on the modeling of the $t\\bar{t}+b\\bar{b}$ background constitute the main source of sensitivity degradation. In order to reduce the impact of ...

Understanding the pointer states

International Nuclear Information System (INIS)

Alexandre Brasil, Carlos; Andreta de Castro, Leonardo

2015-01-01

In quantum mechanics, pointer states are eigenstates of the observable of the measurement apparatus that represent the possible positions of the display pointer of the equipment. The origin of this concept lies in attempts to fill the blanks in Everett’s relative-state interpretation, and to make it a fully valid description of physical reality. To achieve this, it was necessary to consider not only the main system interacting with the measurement apparatus (like von Neumann and Everett did) but also the role of the environment in eliminating correlations between different possible measurements when interacting with the measurement apparatus. The interaction of the environment with the main system (and the measurement apparatus) is the core of the decoherence theory, which followed Everett’s thesis. In this article, we review the measurement process according to von Neumann, Everett’s relative state interpretation, the purpose of decoherence and some of its follow-up until Wojciech Zurek’s primordial paper that consolidated the concept of pointer states, previously presented by Heinz Dieter Zeh. Employing a simple physical model consisting of a pair of two-level systems—one representing the main system, the other the measurement apparatus—and a thermal bath—representing the environment—we show how pointer states emerge, explaining its contributions to the question of measurement in quantum mechanics, as well as its limitations. Finally, we briefly show some of its consequences. This paper is accessible to readers with elementary knowledge about quantum mechanics, on the level of graduate courses. (paper)

Measuring baryon-(anti-)baryon interaction cross-sections with femtoscopy in Heavy-Ion Collisions

Energy Technology Data Exchange (ETDEWEB)

Kisiel, A.

2016-12-15

Two-particle correlations at low relative momentum (femtoscopy) are used to study the space-time dynamics of the source created in heavy-ion collisions. The same method can be used in a novel way to study the Final State Interaction potential for various particle pairs. The parameters are also directly related to the relevant interaction cross-sections. Of special interest are correlations of baryons, where the strong interaction often dominates. The femtoscopic technique offers a unique opportunity to study this interaction in such systems. In this work we discuss the similarities and differences of such measurement for baryon-baryon and baryon-antibaryon pairs.

Qudit-Basis Universal Quantum Computation Using χ^{(2)} Interactions.

Science.gov (United States)

Niu, Murphy Yuezhen; Chuang, Isaac L; Shapiro, Jeffrey H

2018-04-20

We prove that universal quantum computation can be realized-using only linear optics and χ^{(2)} (three-wave mixing) interactions-in any (n+1)-dimensional qudit basis of the n-pump-photon subspace. First, we exhibit a strictly universal gate set for the qubit basis in the one-pump-photon subspace. Next, we demonstrate qutrit-basis universality by proving that χ^{(2)} Hamiltonians and photon-number operators generate the full u(3) Lie algebra in the two-pump-photon subspace, and showing how the qutrit controlled-Z gate can be implemented with only linear optics and χ^{(2)} interactions. We then use proof by induction to obtain our general qudit result. Our induction proof relies on coherent photon injection or subtraction, a technique enabled by χ^{(2)} interaction between the encoding modes and ancillary modes. Finally, we show that coherent photon injection is more than a conceptual tool, in that it offers a route to preparing high-photon-number Fock states from single-photon Fock states.

First observation is reported of semi-inclusive coherent diffractive charged current interactions of antineutrinos on neon nuclei. A sharp peaking towards zero is observed in the | t| distribution of interactions for which the final state charge is 0 and from which only one negative hadron is emitted, unaccompanied by any evidence of nuclear fragmentation or reinteraction. This peak is correlated with high momentum of the outgoing charged hadron and with small values of Q2 and x.

Chronic motivational state interacts with task reward structure in dynamic decision-making.

Cooper, Jessica A; Worthy, Darrell A; Maddox, W Todd

2015-12-01

Research distinguishes between a habitual, model-free system motivated toward immediately rewarding actions, and a goal-directed, model-based system motivated toward actions that improve future state. We examined the balance of processing in these two systems during state-based decision-making. We tested a regulatory fit hypothesis (Maddox & Markman, 2010) that predicts that global trait motivation affects the balance of habitual- vs. goal-directed processing but only through its interaction with the task framing as gain-maximization or loss-minimization. We found support for the hypothesis that a match between an individual's chronic motivational state and the task framing enhances goal-directed processing, and thus state-based decision-making. Specifically, chronic promotion-focused individuals under gain-maximization and chronic prevention-focused individuals under loss-minimization both showed enhanced state-based decision-making. Computational modeling indicates that individuals in a match between global chronic motivational state and local task reward structure engaged more goal-directed processing, whereas those in a mismatch engaged more habitual processing.

Calculation of Rydberg interaction potentials

2017-01-01

The strong interaction between individual Rydberg atoms provides a powerful tool exploited in an ever-growing range of applications in quantum information science, quantum simulation and ultracold chemistry. One hallmark of the Rydberg interaction is that both its strength and angular dependence can be fine-tuned with great flexibility by choosing appropriate Rydberg states and applying external electric and magnetic fields. More and more experiments are probing this interaction at short atomic distances or with such high precision that perturbative calculations as well as restrictions to the leading dipole–dipole interaction term are no longer sufficient. In this tutorial, we review all relevant aspects of the full calculation of Rydberg interaction potentials. We discuss the derivation of the interaction Hamiltonian from the electrostatic multipole expansion, numerical and analytical methods for calculating the required electric multipole moments and the inclusion of electromagnetic fields with arbitrary direction. We focus specifically on symmetry arguments and selection rules, which greatly reduce the size of the Hamiltonian matrix, enabling the direct diagonalization of the Hamiltonian up to higher multipole orders on a desktop computer. Finally, we present example calculations showing the relevance of the full interaction calculation to current experiments. Our software for calculating Rydberg potentials including all features discussed in this tutorial is available as open source. (tutorial)

Simulation of angle-resolved photoemission spectra by approximating the final state by a plane wave: From graphene to polycyclic aromatic hydrocarbon molecules

Energy Technology Data Exchange (ETDEWEB)

Puschnig, Peter, E-mail: peter.puschnig@uni-graz.at; Lüftner, Daniel

2015-04-15

Highlights: • Computational study on angular dependent photoemission spectroscopy. • Graphene and polycyclic aromatic hydrocarbon molecules. • Plane wave final state approximation accounts for experimental findings. - Abstract: We present a computational study on the angular-resolved photoemission spectra (ARPES) from a number of polycyclic aromatic hydrocarbons and graphene. Our theoretical approach is based on ab-initio density functional theory and the one-step model where we greatly simplify the evaluation of the matrix element by assuming a plane wave for the final state. Before comparing our ARPES simulations with available experimental data, we discuss how typical approximations for the exchange-correlation energy affect orbital energies. In particular, we show that by employing a hybrid functional, considerable improvement can be obtained over semi-local functionals in terms of band widths and relative energies of π and σ states. Our ARPES simulations for graphene show that the plane wave final state approximation provides indeed an excellent description when compared to experimental band maps and constant binding energy maps. Furthermore, our ARPES simulations for a number of polycyclic aromatic molecules from the oligo-acene, oligo-phenylene, phen-anthrene families as well as for disc-shaped molecules nicely illustrate the evolution of the electronic structure from molecules with increasing size towards graphene.

Jet energy calibration and a search for supersymmetry with vector boson fusion channel like sign di-τh final states

International Nuclear Information System (INIS)

Rathjens, Denis

2015-08-01

At the LHC, the production of jets has the highest cross section out of all processes. Therefore, jets are important objects for calibration, reconstruction and identification at the CMS experiment. In this thesis, the calibration of the jet energy scale with respect to residual differences between data and simulation after simulation-based precalibrations is shown. A correction for the √(s)=8 TeV run of 2012 depending on jet transverse momentum and pseudorapidity is derived using di-jet final states. Furthermore, the capacity of jets to be misidentified as hadronically decaying τ leptons is demonstrated. A method for an approximate simulation based description of this property is shown in the context of a search for supersymmetry in vector boson fusion final states.

Zc(3900)/Zc(3885) as a virtual state from πJ/ψ - anti D*D interaction

International Nuclear Information System (INIS)

He, Jun; Chen, Dian-Yong

2018-01-01

In this work, we study the πJ/ψ and anti D*D invariant mass spectra of the Y(4260) decay to find out the origin of the Z c (3900) and Z c (3885) structures. The πJ/ψ - anti D*D interaction is studied in a coupled-channel quasipotential Bethe-Saltpeter equation approach, and embedded to the Y(4260) decay process to reproduce both π - J/ψ and D *- D 0 invariant mass spectra observed at BESIII simultaneously. It is found out that a virtual state at energy about 3870 MeV is produced from the interaction when both invariant mass spectra are comparable with the experiment. The results support that both Z c (3900) and Z c (3885) have the same origin, that is, a virtual state from πJ/ψ - anti D*D interaction, in which the anti D*D interaction is more important and the coupling between anti D*D and πJ/ψ channels plays a minor role.

Search for Supersymmetry in Multileptonic Final States with Collimated $\\tau$ Pairs with the ATLAS Detector at the LHC

CERN Document Server

AUTHOR|(CDS)2096586; Kroha, Hubert; Junggeburth, Johannes Josef; Zinonos, Zinonas

The search for supersymmetry (SUSY) is a major part of the ATLAS physics program. Due to the low Standard Model background the search for four-lepton final states provides excellent sensitivity to R-parity violating SUSY models where the lightest supersymmetric particle (LSP), produced in pairs, decay into two charged leptons and a neutrino. For LSP decays into hadronically decaying $\\tau$ pairs, however, the current analysis is not sensitive if the mass difference between the LSP and the next heavier supersymmetric particle is large, because the $\\tau$ jet become highly collimated and the standard $\\tau$ pair reconstruction method is not able to resolve them. A new specialized collimated $\\tau$ pair reconstruction method has been developed for LHC run-2 at 13~TeV center-of-mass energy. In this thesis, the new method is evaluated and optimized for the search for SUSY in four-lepton final states. It is shown, that exclusion limits can be extended to lower LSP masses with the new di-$\\tau$ reconstruction. Fur...

Identification of $\\tau$ leptons and Higgs boson search in the $\\mu+\\tau$ final state at the D0 experiment at the Tevatron

Energy Technology Data Exchange (ETDEWEB)

Madar, Romain [Univ. of Paris, Orsay (France)

2011-01-01

The gauge symmetry is the heart of our understanding of the electroweak interaction and describes all the current experimental results. However, the intrinsic incompatibility between the gauge invariance and the mass of particles leads to the introduction of a new particle, the Higgs boson, for which we have no experimental evidence as of today. This thesis describes the Higgs boson search in the μ + τ final state in 7.3 fb^-1 of pp collisions at √s = 1.96 TeV collected by the DØ detector at the Tevatron. This analysis completes the golden channels (dimuons, electron-muon, dielectrons) exploiting the decay chain H → WW → ℓvℓv , which is the main Higgs boson decay mode in the mass window accessible to the Tevatron. Since the final state includes a lepton, work was done to improve their identification among jets. An increase of 15% was achieved thanks to the the following : changing tuning parameters for the identification neural network, use of the kinematical dependence of the algorithm performances, incorporation of the τ lepton life time information and full study of the additionnal information coming from the central preshower measurements. Then, since the dominant background of the μ + τ Higgs boson search is W+jets (where one jet fakes a τ ), a method was developed to obtain good modeling of this background, not provided by the default simulation. This method is based, among other things, on the charge correlation between the muon and the τ candidate which allows for calibration of this background in the data excluding the signal region. Finally, all the kinematic and/or topological differences between the signal and the background were exploited to optimize this search, reaching an (observed) expected sensitivity of 7.8 (6.6) times the Standard Model for m_H = 165 GeV=c². In addition, this result was also interpreted in a fourth fermion generation scenario. For the first time, this analysis is included in the D
