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 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 کاملTau Polarization in Tau-Neutrino Nucleon Scattering
We investigate the spin polarization of τ leptons produced in ντ and ν̄τ nucleon scattering via charged currents. Quasi-elastic scattering, ∆ resonance production and deep inelastic scattering processes are studied. The polarization information is essential for measuring the τ appearance rate in long baseline neutrino oscillation experiments, because the decay particle distributions depend cruci...
متن کاملLooking for strangeness with neutrino-nucleon scattering
The possibility to determine the axial strange form factor of the nucleon from elastic neutrino-nucleon scattering experiments is studied. The existing experimental information is shortly mentioned and several observables which could be measured in the near future at new neutrino facilities are discussed.
متن کاملImproved analysis of moments of F3 in neutrino-nucleon scattering using the Bernstein polynomial method
We use recently calculated next-to-next-to-leading order (NNLO) anomalous dimension coefficients for the moments of the xF3 structure function in νN scattering, together with the corresponding three-loop Wilson coefficients, to obtain improved QCD predictions for both odd and even moments. To investigate the issue of renormalisation scheme dependence the Complete Renormalization Group Improveme...
