ANGULAR-DISTRIBUTIONS IN THE TAU-]NU-TAU-OMEGA-PI-DECAY MODE

The most general angular decay distribution of the hadronic system in the decay of a polarized tau into one pseudoscalar plus a vector is calculated. Emphasis is put on tau decays in e+e- experiments where the neutrino escapes detection and the tau rest frame cannot be reconstructed. We propose a model for the tau decay into nu(tau)omegapi involving both a vector- and a second class axial vector-current contribution. Then we present numerical results for this decay channel.
