M. K. Volkov, A. B. Arbuzov, D. G. Kostunin

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 $\rho'(1450)$ 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.
