Precise determination of electroweak parameters in neutrino-nucleon scattering.
The NuTeV Collaboration has extracted the electroweak parameter sin(2)theta(W) from the measurement of the ratios of neutral current to charged current nu and (-)nu cross sections. Our value, sin(2)theta((on-shell))(W) = 0.2277 +/- 0.0013(stat) +/- 0.0009(syst), is 3 standard deviations above the standard model prediction. We also present a model independent analysis of the same data in terms o...
متن کاملNuSOnG: A High-Statistics, High-Energy Neutrino Scattering Experiment
The NuSOnG experiment is a proposal for a next-generation high-statistics, high-energy neutrino scattering experiment using an external proton beam, possibly at Fermilab or CERN, to create a high-energy sign-selected neutrino beam. The NuSOnG experiment would have the potential to make much improved electroweak and QCD precision measurements along with direct searches for new physics. The preci...
متن کاملFERMILAB Conf-96/227 UPDATED ELECTROWEAK MEASUREMENTS FROM NEUTRINO-NUCLEON DEEPLY INELASTIC SCATTERING AT CCFR
We report the results of a study of electroweak parameters from observations of neutralcurrent νN deeply inelastic scattering in the CCFR detector at the FNAL Tevatron Quadrupole Triplet neutrino beam. An improved extraction of the weak mixing angle in the on-shell renormalization scheme, incorporating additional data and with an improved technique for constraining systematic errors, is present...
متن کاملReduction of neutrino - nucleon scattering rate by nucleon - nucleon collisions
The collapse-driven supernova is supposed to be an outcome of gravitational collapse of a massive star ∼ 8M at the end of its evolution. Although more than 60 years have passed since the original idea by Baade and Zwicky [1,2], and the detection of neutrinos from SN1987A [3,4] confirmed that our scenario is correct on the whole, we have not yet figured out how this phenomenon occurs. These days...
متن کاملMEASUREMENT 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) = ...
