VMD description of τ → (ω, φ)π − ντ decays and the ω − φ mixing angle

Using the vector meson dominance model we get predictions for the Cabibbo-favored τ − → ωπ − ντ and τ − → φπ − ντ decays. We show how the measurements of these two decays can provide information on the nature of the violation of the OZI rule. PACS numbers: 13.35.Dx, 12.40.Vv, 14.40.Csτ − → ωπ − ντ and τ − → φπ − ντ are two Cabibbo-favored, marginal decay modes of the τ lepton whose precise measurements can give insight into the existence of axial second class currents [1] and on the nature of the violations to the OZI rule [2] in a clean environment, respectively. The decay τ − → ωπ − ντ has been studied previously in the context of the vector-meson dominance model [3], a low energy U(3) × U(3) chiral lagrangian model [4] and, most recently, using the heavy vector-meson chiral perturbation formalism [5]. The experimental information about this decay involves the measurement of the decay rate and the spectral function [6]. The angular distribution of the ωπ − system was found to be consistent with
