Seminar (IFAE)

Hadronic tau decays provide a clean framework for the precise study of QCD in its non-perturbative regime. In this talk I will focus on the exclusive channels $\tau^{-}->K_{S}\pi^{-}\nu_{\tau}$ and $\tau^{-}->K^{-}\eta\nu_{\tau}$ with the purpose to understand both the $K\pi,K\eta$-hadronization as well as to unveil the parameters, such as the mass and the width, of the intermediate resonances that drive these decays. To do so, I will accurately construct the participant form factors, based on arguments of analyticity and unitarity, before presenting our final results.
