The τ to ω,φ π ν τ Decays in the Chiral Model

The \tau \to \omega,\phi \pi^- \nu_\tau decays of the \tau lepton are studied using the method of phenomenological SU(3) * SU(3) chiral Lagrangians. It is shown that the obtained value for the \tau \to \phi \pi \nu_\tau decay probability is very sensitive to deviations from the mixing angle. Calculated partial widths for these decays are compared with the available experimental and theoretical data.
