Chiral Quark Model with Configuration Mixing
The implications of one gluon exchange generated configuration mixing in the Chiral Quark Model (χQMgcm) with SU(3) and axial U(1) symmetry breakings are discussed in the context of proton flavor and spin structure as well as the hyperon β-decay parameters. We find that χQMgcm with SU(3) symmetry breaking is able to give a satisfactory unified fit for spin and quark distribution functions, with...
متن کاملConfiguration Mixing in Relativistic Quark Models
Starting from the standard and commonly used relativistic nucleon wave function, we show that residual interactions based on gluon or Goldstone boson exchanges generate additional components leading to configuration mixing. This result suggests that realistic nucleon wave functions can be expected to be far more complex than seemingly successful form factor fits in relativistic quark models wou...
متن کاملBs−Bs mixing with a chiral light quark action
We study the B 0 s − B 0 s mixing amplitude in Standard Model by computing the relevant hadronic matrix element in the static limit of lattice HQET with the Neuberger light quark action. In the quenched approximation, and after matching to the MS scheme in QCD, we obtain B MS B s (m b) = 0.940(16)(22). c Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCom...
متن کاملChiral Quark Model
Abstract. In this talk I review studies of hadron properties in bosonized chiral quark models for the quark flavor dynamics. Mesons are constructed from Bethe–Salpeter equations and baryons emerge as chiral solitons. Such models require regularization and I show that the two–fold Pauli–Villars regularization scheme not only fully regularizes the effective action but also leads the scaling laws ...
متن کاملChiral Quark Model of Mesons
We study SU(3)L×SU(3)R chiral quark model of mesons up to next leading order of 1/Nc expansion. Composite vector and axial-vector mesons resonances are introduced via non-linear realization of chiral SU(3) and vector meson dominant. Effects of one-loop graphs of pseudoscalar, vector and axial-vector mesons is calculated systematically and the significant results are obtained. Correction of effe...
