A proposal for improving the hadronization of QCD currents in TAUOLA

Abstract

After overviewing the general features of semileptonic decays of the tau lepton, I will recall the most widely used model for them, namely that of Kuhn-Santamaria (KS), and I will explain the subsequent works that were done along these lines and that are implemented in the TAUOLA library for analysing tau decays. After that, I will move to the description of our project that aims to achieve a theory as close as possible to QCD for the considered decays. I conclude by emphasizing the importance of the implementation of our work in TAUOLA.
