Measurement of the tau lifetime with the DELPHI detector
The tau lepton lifetime has been measured with the $e^{+}e^{-}$ to tau /sup +/ tau /sup -/ 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 tau decay channels. These are combined with previously p...

| Sumario: | The tau lepton lifetime has been measured with the $e^{+}e^{-}$ to tau /sup +/ tau /sup -/ 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 tau decay channels. These are combined with previously published DELPHI results to provide a tau lifetime measurement of tau /sub tau /=290.9+or-1.4/sub stat/+or-1.0/sub sys/ fs, using the full LEP1 data sample. |
