Descripción
We analyze the hadronization structure of both vector and axial-vector currents leading to tau -> K K pi nu_tau decays. At leading order in the 1/NC expansion, and considering only the contribution of the lightest resonances, we work out, within the framework of the resonance chiral Lagrangian, the structure of the local vertices involved in those processes. The couplings in the resonance theory are constrained by imposing the asymptotic behavior of vector and axial-vector spectral functions ruled by QCD. In this way we predict the hadron spectra and conclude that, contrary to previous assertions, the vector contribution dominates by far over the axial-vector one in all K K pi charge channels.
