  "abstract": "In the extended Nambu--Jona-Lasinio model, the decay widths of the processes $\\tau \\to [\\omega(782), \\phi(1020)] K^{-} \\nu_{\\tau}$ were calculated. The intermediate strange quark-antiquark mesons in both the ground and the first radially excited states were taken into account. The meson $K_{1}(1400)$, being a possible candidate for the role of the tetraquark meson, was also taken into account as an intermediate state. The result for the process $\\tau \\to \\omega(782) K^{-} \\nu_{\\tau}$ is in satisfactory agreement with the experimental data. Simultaneously, the result for the decay $\\tau \\to \\phi(1020) K^{-} \\nu_{\\tau}$ is in agreement with the experimental data with precision $1.3 \\sigma$.",
