摘要：

The tau lepton decays tau -> [(K-K0)pi(0), K-K+pi(-), K-0((K) over bar)(0)pi(-)]nu(tau )are described in the U(3) x 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-0*. The obtained results are in satisfactory agreement with the recent experimental data within the experimental and theoretical uncertainties.
