摘要：

We report final results on electroweak parameters from muon-neutrino electron scattering observed in the CHARM II detector from 1987 till 1991. In total 2677 +/- 82 and 2752 +/- 88 neutrino-electron scattering events have been detected in the nu and nuBAR-beam, respectively. From the ratio of differential cross sections we obtain for the electroweak mixing angle sin2 THETA(nue) = 0.2324 +/- 0.0083. From the absolute neutrino-electron scattering event rate we determined the effective vector and axial-vector neutral current coupling constants to be g(v)nue = -0.035 +/-0.017 and g(A)nue = -0.503 +/- 0.017.
