Hadronic tau decays

Abstract

This talk summarizes our current knowledge on the decays of {tau} leptons into hadrons. The decays are discussed in terms of the hadronic weak currents and compated to theoretical predictions. The presented topics include: the QCD analysis of the hadronic decay width and the determination of the strong coupling constant at the {tau} mass scale, analyses of the pion form factor and the a{sub 1}(1260) resonance parameters, improved limits on second class currents, analyses of the Lorentz structure of the {tau} - {nu}{sub {tau}} vertex and limits on the {tau} neutrino mass. Also discussed is the (still existing) deficit in the exclusive {tau} decay branching ratios. (orig.)
