Abstract.

In the extended Nambu-Jona-Lasinio model, the decay widths of the processes \( \tau \rightarrow [\omega(782), \phi(1020)] K^{-} \nu_{\tau}\) were calculated. The intermediate channels with axial vector (\(K_{1} (1270)\), \( K_{1} (1400)\) and \( K_{1} (1650)\)), vector (\( K^{\ast} (892)\) and \( K^{\ast} (1410)\)) and pseudoscalar (K and \( K(1460)\)) mesons were considered. The results for these processes are in satisfactory agreement with the experimental data.
