Wk report the determination of sin(2) theta(W) in nu - N deep inelastic sca
ttering from the NuTeV experiment. Using separate neutrino and anti-neutrin
o beams, NuTeV is able to extract sin2 Bw with low systematic errors from t
he Paschos-Wolfenstein variable R-, a ratio of differences of neutrino and
antineutrino neutral-current and charged-current cross-sections. NuTeV meas
ures sin(2) theta(W)((on-shell)) = 0.2253 +/- 0.0019(stat) +/- 0.0010(syst)
, which implies M-W = 80.26 +/- 0.11 GeV.
