Tau Physics: Theory Overview
arXiv:0806.2793 · doi:10.1016/j.nuclphysbps.2008.09.054
Abstract
The present status of some selected topics on tau physics is presented: charged-current universality tests, bounds on lepton-flavour violation, the determination of alpha_s from the inclusive tau hadronic width, the measurement of |V_{us}| through the Cabibbo-suppressed decays of the tau, and the theoretical description of the "tau -> nu_tau K pi" spectrum.
