Abstract

The BaBar collaboration has accumulated over 400 million tau-pairs which can be used to study charged leptonic and hadronic weak currents to unprecedented precision. This note presents results on lepton universality, measurements of |V_us|, and searches for tau decays which violate lepton flavour conservation, or tau decays that proceed through a suppressed second class current.
