Abstract
The \\tau \\to ømega,\\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.
