Abstract

The full and differential widths of the decay $τ \to K^{0} K^{-} ν_{τ}$ are calculated in the framework of the extended Nambu–Jona-Lasinio model.The contributions of the subprocesses with the intermediate vector mesons $ρ$ (770) and $ρ$ (1450) are taken into account. The obtained results are in satisfactory agreement with the experimental data.
