Abstract
The $\stackrel{\ensuremath{\rightarrow}}{\ensuremath{\tau}}\mathrm{VP}{\ensuremath{\nu}}_{\ensuremath{\tau}}$ decays of the $\ensuremath{\tau}$ lepton are studied using the method of phenomenological chiral Lagrangians. The expressions of weak hadronic currents between pseudoscalar and vector meson states and the strong interaction Lagrangian between axial-vector, vector, and pseudoscalar mesons are obtained. Calculated partial widths for these decays are compared with the available theoretical and experimental data.
