Measurement of the tau lifetime and leptonic branching ratios in L3
Using data collected with the L3 detector near the Z resonance corresponding to an integrated luminosity of 150 pb/sup -1/ the lifetime of the tau lepton is measured to be tau /sub tau /=293.2+or-2.0 (stat.)+or-1.5(sys.) fs, and the branching ratios of the tau lepton into electron and muon are measu...
