Overview of tau lepton physics at a super tau-charm facility

Abstract

An overview of tau lepton physics is presented, using the tau lepton discovery and its precision measurements as examples to illustrate the importance of the energy region to be covered by the super tau-charm factory. By presenting the current measurement status of the major physics topics, the emphasize is put on pointing out a few open issues and possibilities for the super tau-charm factory.
