Abstract

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