Contribution

It introduces an extended NJL model with heavy quark flavors and applies it to compute decay properties of vector mesons.

Findings

Calculated decay widths for light and heavy vector mesons.

Demonstrated the model's capability to describe meson decay processes.

Provided predictions for meson decay channels not yet measured.

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 $\rho$, $\omega$, $K^*$, $\phi$ and heavy $D^*$, $D^*_s$, $B^*$, $B^*_s$.
