The τ lepton is the heaviest of the charged leptons and the only one to decay into hadrons. This provides a unique opportunity to probe low energy QCD and the charged weak interaction of both the relative coupling strength to the first and second generation of quarks and to the lepton. Moreover, many new physics scenarios couple primarily to the third generation, making it a promising prospect for new physics searches. In this paper, an overview of recent measurements of the τ lepton from BABAR, BELLE and BES are presented.
I would like to thank conference organizers, F. Curciarello, V. De Leo, G. Fazio , G. Giardina, G. Mandaglio and F. Mammoliti, and S. Eidelman for giving me this opportunity to present recent results on τ decays. Personal support for Ian M. Nugent was provided by the Alexander Von Humboldt Foundation.
