Abstract
The recent measurement of the τ−→KSπ−ντ spectrum by the Belle Collaboration provides the frame to set forth a theoretical description of the decay, which is based on the contributing vector and scalar form factors. 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 .
