New results on {tau} physics from LEP

Abstract

New experimental results regarding {tau} decays from the LEP experiments ALEPH, Delphi, L3, and OPAL, including data from 1991 are presented. New values for the {tau} lifetime, including early results with silicon vertex detectors are given. Updated measurements of {tau} decay branching fractions are presented. The relevance of these measurements to the known discrepancies in previous observations is discussed. Polarization results of the {tau} from Z{sup 0} decays are provided. (orig.).
