Abstract

We have used a high-resolution drift chamber in the Mark II detector at the SLAC storage ring PEP to measure the lifetime of leptons produced in e+e- annihilations at 29 GeV. Based on the flight-path distribution of 807 three-prong decays, the lifetime is found to be (2.880.16 0.17)×10-13 sec, in agreement with expectations for e - universality. © 1988 The American Physical Society.
