Polarization effects of the $\tau \rightarrow K^{-} \pi^{0} \nu_{\tau}$ process in the Nambu–Jona-Lasinio model

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