Tau Electroweak Couplings

Abstract

We review world-average measurements of the tau lepton electroweak couplings, in both decay (including Michel parameters) and in production ($Z^0\to {\tau }^{+}{\tau }^{-}$ and $W^-\toτ^-\nubar_τ$). We review the searches for anomalous weak and EM dipole couplings. Finally, we present the status of several other tau lepton studies: searches for lepton flavor violating decays, neutrino oscillations, and tau neutrino mass limits.
