Repond, J

We summarize recent measurements by the HRS collaboration of the topological branching fractions, the production cross section, the lifetime, and the rate into electrons of the {tau} lepton. An inconsistency with theoretical expectations persists at the level of two standard deviations. 11 refs., 2 figs., 4 tabs.
