DELPHI $\tau$ lifetime results using all LEP-1 data
Using events collected by the DELPHI detector at LEP in the years 1991-1995, the tau lepton lifetime has been measured to be (290.7+-1.5+-1.0) fs. Three different methods have been exploited utilising decays of the tau into final states containing one or three charged tracks. (6 refs).
