Radiative decays of pseudoscalar P and vector V mesons and the process e+e-→PV

Radiative decays of pseudoscalar and vector mesons are calculated in frames of chiral Nambu-Jona-Lasinio (NJL) model. We use triangle quark loops of anomalous type. During the evaluation of this loop integrals we used two methods. In first one we neglect the dependence of external momenta. In that case we reproduce the Wess-Zumino-Witten terms of effective chiral meson lagrangian. In the second method we take into account the momenta dependence of loop integrals omitting their imaginary part. That lets us to take into account quark confinement. The application of both methods are in qualitative agreement with each other and with experimental data. Second method allows us to describe the electron-positron annihilation with production pseudoscalar and vector mesons in center of mass energy range from 1 to 5 GeV. The comparison with the recent experimental data are presented
