摘要：

We are reporting an improved determination of the electroweak mixing angle sin2-THETA-w from the ratio of nu-mu-e to nuBAR-mu-e scattering cross sections. The CHARM II detector was exposed to neutrino and antineutrino wide band beams at the 450 GeV CERN SPS. Including new data collected in 1989 we have obtained 1316 +/- 56-nu-mu-e and 1453 +/- 62-nuBAR-mu-e events. From the ratio of the visible cross sections we determined sin2-THETA-0 = 0.239 +/- 0.009 (stat) +/- 0.007 (syst) without radiative corrections and g(V)e/g(A)e = 0.047 +/- 0.046. Combining this last result with recent results on g(A)e at LEP we obtain g(V)e = - 0.023 +/- 0.023.
