Decay widths of radially excited vector mesons of the $U(3)$ nonet with production of three pseudoscalar mesons in the extended NJL model

Abstract

In the extended NJL model, the decays of the first radially excited vector mesons $\rho'$,$\omega'$, $\phi'$ and ${K^*}'$ with production of $3P$, where $P=K,\pi,\eta$ are calculated. The box channels and the channels with intermediate vector mesons in the ground and first radially excited states are considered. The obtained results can be considered as predictions for future experiments.
