L3 measurement of the $\tau$ lepton lifetime
The tau lepton lifetime is measured with the L3 detector at LEP. For the analysis presented here tau pairs produced during 1994 and 1995 around the Z pole are used. The measurement is done by a decay length method for the 3-prong tau decays and by an impact parameter analysis for the 1-prong decays....
