Abstract The angular distributions of the reactione + e −→μ+μ− ande + e +→τ+τ− have been measured between $$\sqrt s = 50$$ and 60.8 GeV with the VENUS detector at TRISTAN. The average total cross section and the forward-backward charge asymmetry for μ-pair production are observed to be 28.3±1.4±0.8 pb and (−29.0 −4.8 +5.0 ±0.5)%, and those for τ-pair production are 27.6±1.7±1.0 pb and (−32.8 −6.2 +6.4 ±1.5)% at $$\langle \sqrt s \rangle $$ . These values are consistent with the predictions of the standard model of electroweak interactions.
