Measurement of the tau lifetime in Aleph

An updated measurement of the tau lepton mean lifetime is presented. Several methods are used to analyze the one-prong and three-prong tau decays in a data sample collected in 1993 and 1994 with the ALEPH detector at LEP. The new data increases the size of the analyzed ALEPH tau sample by more than...

Sumario:An updated measurement of the tau lepton mean lifetime is presented. Several methods are used to analyze the one-prong and three-prong tau decays in a data sample collected in 1993 and 1994 with the ALEPH detector at LEP. The new data increases the size of the analyzed ALEPH tau sample by more than a factor of three, compared to previously published measurements.
