(\omega, \phi) P^- decays of tau leptons

Abstract

The \tau -> (\omega, \phi)P^-\nu decays, where P^-=\pi^-, K^-, are considered within a phenomenological model with dominance of meson intermediate states. We assume SU(3) flavor symmetry to fix some of the unknown strong interaction couplings. Our predictions for the \tau -> \phi (\pi^-, K^-)\nu branching fractions are in good agreement with recent measurements of the BABAR and BELLE Collaborations.
