Title: Microscopic derivation of the pion coupling to heavy-light mesons

Abstract

The Goldberger-Treiman relation for heavy-light systems is derived in the context of a quark model. As a paradigmatic example, the case of D{yields}D{sup '}{pi} is studied in detail. The fundamental role played by the pion two-component wave function, in the context of the Salpeter equation, is emphasized.

  • The strong coupling constants of the heavy spin-1/2 and spin-3/2 baryons with light pseudoscalar and vector mesons are calculated in the framework of the light cone QCD sum rules. Using the symmetry arguments, some structure independent relations among different correlation functions are obtained. It is shown that all possible transitions are described by only one invariant function, whose explicit expression is structure dependent.
  • By use of a single-instanton approximation the twist-three light-cone distribution amplitudes of the pion as well as the p-wave mesons, i.e., f{sub 0}(1370), K{sub 0}*(1430), and a{sub 0}(1450), are investigated within the framework of QCD moment sum rules with the inclusion of instanton effects based on the valence quark model. The results show that there is much change on light-cone distribution amplitudes due to the isospin- and chirality-dependent instanton contribution compared with the instanton-free ones. We find that the instanton-involved twist-three light-cone distribution amplitudes are non-positive-definite within some range of the momentum fraction and that there are rapid changes atmore » two ends of the momentum fraction. To guarantee the convergence of moments using the method in this work, a low instanton density should be adopted; for instance, n{sub c}=(1/2) fm{sup -4}. Possible ingredients which might have an impact on the results are briefly discussed. These light-cone distribution amplitudes may be helpful to analyze exclusive heavy-flavored processes.« less
  • Nuclear collisions from 0.3 to 2 GeV nucleon are studied in a microscopic theory based on Vlasov's self-consistent mean field and Uehling-Uhlenbeck's two-body collision term which respects the Pauli principle. The theory explains simultaneously the observed collective flow and the pion multiplicity and gives their dependence on the nuclear equation of state.
  • A common pattern of large orbital and radial excitations in heavy-light and light-light mesons is demonstrated. For a general potential model with linear confinement the Regge slopes of the light degrees of freedom for these mesons are shown to be in the ratio of 2. The possibility of `tower` degeneracy occurs only with pure scalar confinement. {copyright} {ital 1997} {ital The American Physical Society}
  • The spectra of light-light and heavy-light mesons are calculated within the framework of the QCD string model, which is derived from QCD in the Wilson loop approach. Special attention is paid to the proper string dynamics that allows us to reproduce the straight-line Regge trajectories with the inverse slope being 2{pi}{sigma} for light-light and twice as small for heavy-light mesons. We use the model of the rotating QCD string with quarks at the ends to calculate the masses of several light-light mesons lying on the lowest Regge trajectories and compare them with the experimental data as well as with themore » predictions of other models. The masses of several low-lying orbitally and radially excited heavy-light states in the D, D{sub s}, B, and B{sub s} mesons spectra are calculated in the einbein (auxiliary) field approach, which has proven to be rather accurate in various calculations for relativistic systems. The results for the spectra are compared with the experimental and recent lattice data. It is demonstrated that an account of the proper string dynamics encoded in the so-called string correction to the interquark interaction leads to an extra negative contribution to the masses of orbitally excited states that resolves the problem of the identification of the D(2637) state recently claimed by the DELPHI Collaboration. For heavy-light system we extract the constants {bar {Lambda}}, {lambda}{sub 1}, and {lambda}{sub 2} used in heavy quark effective theory and find good agreement with the results of other approaches.« less
