Shadowing and Antishadowing in Neutrino Deep Inelastic Scattering
The weak-mixing angle sin θW is an essential parameter in the standard model of electroweak interactions. Until recently, a consistent value was obtained from all electroweak observables 1. However, the NuTeV Collaboration 2 has determined a value for sin θW from measurements of the ratio of charged and neutral current deep inelastic neutrino–nucleus and anti-neutrino–nucleus scattering in iron...
متن کاملNuclear Shadowing in Neutrino Deep Inelastic Scattering
We discuss effect of nuclear shadowing in neutrino deep-inelastic scattering in terms of non perturbative parton model. We found that for small Bjorken x and large Q2 the structure function F3 is shadowed in nuclei about two times as stronger as F2. The underlying reason and phenomenological aspects of this observation are discussed. Key-words: neutrino, deep inelastic scattering, nuclear effec...
متن کاملNuclear PDFs from neutrino deep inelastic scattering
We study nuclear effects in charged current deep inelastic neutrino–iron scattering in the framework of a χ-analysis of parton distribution functions. We extract a set of iron PDFs and show that under reasonable assumptions it is possible to constrain the valence, light sea and strange quark distributions. We compare our results with nuclear parton distribution functions from the literature and...
متن کاملSome Aspects of Nuclear Deep Inelastic Scattering
Nuclear deep inelastic scattering is considered in the framework of a model in which the current operator explicitly satis es Poincare invariance and current conservation. The results considerably di er from the standard ones at small values of the Bjorken variable x. In particular, it is impossible to extract the neutron structure functions from the deuteron data at x < 0:01 and we predict tha...
متن کاملPositivity constraints for lepton polarization in neutrino deep inelastic scattering
We consider the spin polarization of leptons produced in neutrino and antineutrino nucleon deep inelastic scattering, via charged currents, and we study the positivity constraints on the spin components in a model independent way. These results are very important, in particular in the case of τ leptons, because the polarization information is crucial in all future neutrino oscillation experimen...
