Abstract

The precise determination of electroweak parameter in neutrino-nucleon scattering was discussed. The electroweak parameter sin2θw was extracted by measuring the ratios of neutral current to charged current. The value of sin2θW(on-shell) = 0.2277 ± ±0.0013(stat) ± 0.0009(syst) was obtained which is 3 standard deviations above the standard model prediction.
