In the extended Nambu-Jona-Lasinio model, the decay widths of the processes ![$ \tau \rightarrow [\omega(782), \phi(1020)] K^{-} \nu_{\tau}$](/articles/epja/abs/2019/09/10050_2019_Article_12872/10050_2019_Article_12872_tex_eq2.png)
were calculated. The intermediate channels with axial vector (
, 
and 
), vector (
and 
) and pseudoscalar (K and 
) mesons were considered. The results for these processes are in satisfactory agreement with the experimental data.
