Chiral 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...
متن کاملMesons in non-local chiral quark models
After briefly reviewing chiral quark models with non-local regulators and listing their advantages over the conventional Nambu-Jona-Lasioniolike models, we study vector meson correlators in both types of approaches. Since effective chiral quark models are valid in the Eulidean domain only, with −0.5GeV ≤ q ≤ 0, in our study the meson correlators are not described directly, but with help of a me...
متن کاملA quark loop model for heavy mesons
I consider a model based on a quark–meson interaction Lagrangian. The transition amplitudes are evaluated by computing diagrams in which heavy and light mesons are attached to quark loops. The light chiral symmetry relations and the heavy quark spin-flavour symmetry dictated by the heavy quark effective theory are implemented. The model allows to compute the decay form factors and therefore can...
متن کاملExpansion in Chiral Quark Model of Mesons
We study SU(3)L×SU(3)R chiral quark model of mesons up to the next to 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. We also inv...
متن کاملFour - Quark Model for the Mesons
A four-quark mechanism is proposed which generates virtually the entire known spectrum of (non-charm) meson states to remarkable accuracy. The ground state Oand lnonets are taken as input; exclusive of octetsinglet mixing there are no free parameters. (Submitted to Phys. Rev. Lett.)
