The decay $\tau \to K^0{K}^{-}{\nu }_{\tau }$ in the extended Nambu-Jona-Lasinio model

Abstract

The full and differential widths of the decay $\tau \to K^0{K}^{-}{\nu }_{\tau }$ are calculated in the framework of the extended Nambu-Jona-Lasinio model. The contributions of the subprocesses with the intermediate vector mesons $\rho$(770) and $\rho$(1450) are taken into account. The obtained results are in satisfactory agreement with the experimental data.
