Abstract
We report the measurement of sin2 thetaW in nu N deep inelastic scattering from the NuTeV experiment. By using separate neutrino and anti-neutrino beams, NuTeV is able to determine sin2 thetaW with smaller systematic and similar or smaller statistical errors when compared to previous neutrino experiments. NuTeV measures sin2 thetaW (on-shell) = 0.2253 +/- 0.0019(stat.) +/- 0.0010(sys.), which implies MW = 80.26 +/- 0.11 GeV/c2.
