Tau lifetime and decays

Abstract

Recent results of a high-statistics study of tau lepton properties and decays at B factories are reviewed. We discuss measurements of tau lifetime, branching fractions, and spectral functions for several hadronic tau decay modes with $K^0_S$. Results of a search for lepton flavor violating tau decays as well as CP symmetry violation are briefly discussed.Comment: Presented at the 2014 Flavor Physics and CP Violation (FPCP-2014), Marseille, France, May 26-30 2014, 19 pages, 8 figures, 3 table
