Abstract

We have determined the τ lifetime in e⁺e^- annihilations at an average centre of mass energy of 42.5 GeV, using a pressurized drift chamber close to the interaction point. We find the lifetime to be (3.18_-0.75 ^+0.59 ± 0.56) × 10^-13 s. The charged weak τ coupling constant relative to that of the μ is found to be G_τ/G_μ = 0.94_-0.09 ^+0.12 ± 0.09, in good agreement lepton universality.
