MEASUREMENT OF sin θW FROM NEUTRINO-NUCLEON SCATTERING AT NuTeV
We report the measurement of sin θW in ν − N deep inelastic scattering from the NuTeV experiment. Using separate neutrino and anti-neutrino beams, NuTeV is able to determine sin θW with low systematic errors by measuring the Paschos-Wolfenstein variable R, a ratio of differences of neutrino and anti-neutrino neutral-current and charged-current cross-sections. NuTeV measures sin θW (on−shell) = ...

متن کامل0 Electroweak Physics at NuTeV G . P . Zeller for the NuTeV
The NuTeV experiment at Fermilab presents a determination of the elec-troweak mixing angle. High purity, large statistics samples of ν µ N and ν µ N events allow the use of the Paschos-Wolfenstein relation, a technique which considerably reduces systematic errors associated with charm production and other sources. Within the Standard Model, this measurement of sin 2 θ W indirectly determines th...

The NuTeV Collaboration has measured the electroweak parameters sin 2 θ W and ρ in neutrino-nucleon deep-inelastic scattering using a sign-selected beam. The nearly pure ν or ¯ ν beams that result provide many of the cancellations of systematics associated with the Paschos-Wolfenstein relation. The extracted result for sin 2 θ W (on-shell) = 1 − M 2 W /M 2 Z is three standard deviations from pr...
