The decays $τ\to [K^- K^0 π^0, K^- K^+ π^-, K^0 \bar{K^0} π^-] ν_τ$ in the NJL quark model

The $τ$ lepton decays $τ \to [K^{-} K^{0} π^{0}, K^{-} K^{+} π^{-}, K^{0} \overset{ˉ}{K^{0}} π^{-}] ν_{τ}$ are described in the $U (3) \times U (3)$ NJL quark model. The contact channel and intermediate channels with axial-vector, vector and pseudoscalar mesons are taken into account. It is shown that the strange scalar meson $K_{0}^{*}$ plays an important role in these processes in addition to the intermediate vector meson $K^{*}$ . The obtained results are in satisfactory agreement with the recent experimental data within the experimental and theoretical uncertainties.
