A precise measurement of the tau lifetime

The tau lepton lifetime has been measured with the e+e - → τ+τ- events collected by the DELPHI detector at LEP in the years 1991-1995. Three different methods have been exploited, using both one-prong and three-prong τ decay channels. Two measurements have been made using events in which both taus d...
