Abstract

The angular distributions of the reaction e+e-→μ+μ- and e+e+→τ+τ- have been measured between {Mathematical expression} 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 {Mathematical expression}. These values are consistent with the predictions of the standard model of electroweak interactions.

N2 - The angular distributions of the reaction e+e-→μ+μ- and e+e+→τ+τ- have been measured between {Mathematical expression} 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 {Mathematical expression}. These values are consistent with the predictions of the standard model of electroweak interactions.
