The polarization effects of the process $\tau \to K^{-}{\pi }^0{\nu }_{\tau }$ in the Nambu--Jona-Lasinio model

Abstract

The polarization effects of the processes $\tau \to K^{-}{\pi }^0{\nu }_{\tau }$ are described in the framework of the Nambu--Jona-Lasinio model. The intermediate vector meson $K^{\ast }(892)$ is taken into account. The contribution of these effects to the differential decay width is obtained.
