✦ Synopsis

We report the determination of sin e0w in ~ -N deep inelastic scattering from the NuTeV experimeat.

Using separate neutrino and anti-neutrino beams, NuTeV is able to extract sin 2 0u" with low systematic errors from the Paschos-Wolfenstein variable R-, a ratio of differences of neutrino and antineutrino neutral-current and charged-current crosssections.

NuTeV measures sin 2 0w (°n-shell) = 0.2253 :t: 0.0019(stat) :t: 0.0010(syst), which implies Mw= 80.26 ± 0.11 GeV.
