The decays $\tau \to [\omega (782),\varphi (1020)]K^{-}{\nu }_{\tau }$ in the extended NJL model

Abstract

In the extended Nambu--Jona-Lasinio model, the decay widths of the processes $\tau \to [\omega (782),\varphi (1020)]K^{-}{\nu }_{\tau }$ were calculated. The intermediate channels with axial vector ($K_1(1270)$, $K_1(1400)$ and $K_1(1650)$), vector ($K^{\ast }(892)$ and $K^{\ast }(1410)$) and pseudoscalar ($K$ and $K(1460)$) mesons were considered. The results for these processes are in satisfactory agreement with the experimental data.
