Abstract

We update the calculation of the decays of the τ lepton into various modes using recent data on electron-positron annihilation into hadrons plus bounds that follow from isotopic-spin conservation. Comparison is made with exclusive branching-ratio data and inclusive charged-prong-distribution measurements in τ decays, and the difficulty in accounting for all the one-charged-prong decays as a sum of exclusive decay modes is discussed.
