Abstract
A preliminary measurement of sin2 θW in ν−N deep inelastic scattering from the NuTeV experiment is presented. Using separate neutrino and antineutrino beams, NuTeV is able to determine sin2 θW with low systematic errors. NuTeV measures sin2 θW(on–shell)=0.2253±0.0019(stat)±0.0010(syst), which implies MW=80.26±0.11 GeV. Expectations are also presented for the NuTeV search for νμ→ντ and νμ→νe oscillations using the measured neutral to charged-current ratio. The future BooNE experiment is described which searches for νμ→νe appearance and νμ disappearance oscillations using a new neutrino beam created from the Fermilab 8 GeV Booster accelerator. The experiment is designed to cover definitively the δm2/sin2 2θ region associated with the possible oscillation signal from the LSND experiment and to measure accurately the oscillation parameters if a signal is observed.
