Abstract

We present an analysis of electroweak leptonic couplings from high statistics experiments on Bhabha scattering and μ pair production at an energy of 34.5 GeV. The forward-backward charge asymmetry of the μ pairs was measured to be -0.098±0.023±0.005. The data were found to agree well with the standard theory of electroweak interaction giving sin²θ_W=0.27±0.07. The leptonic weak couplings were determined to be g_v=0.000±0.170 and g_A=-0.481±0.055. The data were also used to investigate a class of composite models for leptons.
