We show that a good representation of data is obtained through the use of form factors calculated within resonance chiral theory and constrained by dispersion relations and short-distance QCD. Hence we obtain a determination of K*(892) parameters and the low-energy parameterization of F_+(s).4 pages, 2 figuresHigh Energy Physics - PhenomenologyAnalysis of tau -> Ks pion nu_tau Belle data in a chiral frameworktext
