Abstract
A measurement of the lifetime of the tau lepton has been made using a sample of 1671 Z(0) --> tau(+)tau(-) decays collected by the SLD detec tor at the SLC. The measurement benefits from the small and stable col lision region at the SLC and the precision pixel vertex detector of th e SLD. Three analysis techniques have been used: decay length, impact parameter, and impact parameter difference methods. The combined resul t is tau(tau) = 297 +/- 9(stat) +/- 5(syst) fs.
