Vector meson couplings to vector and tensor currents in extended NJL quark model
PACS: 12.39.Ki, 14.40.Cs
Abstract
A simple explanation of the dynamic properties of vector mesons is given in the framework of extended Nambu-Jona-Lasinio quark model. New mass relations among the hadron vector resonances are derived. The results of this approach are in good accordance with the QCD sum rules, the lattice calculations and the experimental data.
