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 کاملSome model-independent properties of quark mixing
We discuss some new invariants of quark mixing and show their usefulness with a simple example. We also present some other new tools for analyzing quark mixing. ∗ talk presented at the Yukawa couplings and the origin of mass workshop, February 1994, University of Florida, Gainesville, Florida ∗∗address after September 1, 1994: Department of Physics, University of Pennsylvania, Philadelphia, PA ...
متن کاملMixing , and the Quark
The momentum-dependence of the ρ 0-ω mixing contribution to charge-symmetry breaking (CSB) in the nucleon-nucleon interaction is compared in a variety of models. We focus in particular on the role that the structure of the quark propagator plays in the predicted behaviour of the ρ 0-ω mixing amplitude. We present new results for a confining (entire) quark propagator and for typical propagators ...
متن کاملCp Violation and Quark Mixing Cp Violation and Quark Mixing
Measurements of CP asymmetries in B decays will soon be made at B factories and hadron machines. In light of this, we review and update the profile of the CKM unitarity triangle and the resulting CP asymmetries in B decays. This is done both in the standard model and in several variants of the minimal supersymmetric standard model (MSSM), which are characterized by a single phase in the quark f...
