Meson Decays in an Extended Nambu--Jona-Lasinio model with Heavy Quark Flavors

Abstract

In a previous work, we proposed an extended Nambu--Jona-Lasinio (NJL) model including heavy quark flavors. In this work, we will calculate strong and radiative decays of vector mesons in this extended NJL model, including light $\rho$, $\omega$, $K^{\ast }$, $\varphi$ and heavy $D^{\ast }$, $D_s^{\ast }$, $B^{\ast }$, $B_s^{\ast }$.
