Description of the decay $\tau \to K\pi \pi {\nu }_{\tau }$ in the NJL type chiral quark model

Volkov M. K., Pivovarov A. A., Nurlan K

The branching fractions of the decays ${\tau }^{-}\to K^{-}{\pi }^{+}{\pi }^{-}{\nu }_{\tau }$, ${\tau }^{-}\to K^{-}{\pi }^0{\pi }^0{\nu }_{\tau }$ and ${\tau }^{-}\to {\bar{K}}^0{\pi }^{-}{\pi }^0{\nu }_{\tau }$ are calculated in the $U(3)\times U(3)$ Nambu--Jona-La…
