(ω, ϕ) P^- decays of tau leptons

Abstract
The τ-> (ω, ϕ)P^-νdecays, where P^-=π^-, 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 τ-> ϕ(π^-, K^-)νbranching fractions are in good agreement with recent measurements of the BABAR and BELLE Collaborations.
