The decay $\tau \to \pi \omega \nu$ in the extended NJL model

Abstract

The decay width $\tau \to \pi \omega \nu$ in the framework of the extended NJL model is calculated. The contributions of the intermediate vector mesons $\rho (770)$ and ${\rho }^{\prime }(1450)$ are taken into account. The computed partial width and the spectral function of the decay $\tau \to \pi \omega \nu$ are in satisfactory agreement with experimental data.
