Nuclear Shadowing in Neutrino Deep Inelastic Scattering

نویسنده

  • S. A. Kulagin
چکیده

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 effects, nuclear shadowing

Shadowing in neutrino deep inelastic scattering and the determination of the strange quark distribution

We discuss shadowing corrections to the structure function F2 in neutrino deep-inelastic scattering on heavy nuclear targets. In particular, we examine the role played by shadowing in the comparison of the structure functions F2 measured in neutrino and muon deep inelastic scattering. The importance of shadowing corrections in the determination of the strange quark distributions

Nuclear Corrections in Neutrino Deep Inelastic Scattering and the Extraction of the Strange Quark Distribution

Recent measurement of the structure function F ν 2 in neutrino deep inelastic scattering allows us to compare structure function measured in neutrino and charged lepton scattering for the first time with reasonable precision. The comparison between neutrino and muon structure functions made by the CCFR Collaboration indicates that there is a discrepancy between these structure functions at smal...

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...

Nuclear Shadowing at Low Q

In the light of a recent claim that models of nuclear shadowing which incorporate a vector meson dominance component at low Q2 are incompatible with nuclear deep inelastic scattering data, we compare the predictions of such a model with high precision data on the Q2 dependence of nuclear shadowing. Contrary to this claim, we find that models which incorporate both vector meson and partonic mech...

Comparison of Neutrino and Muon Structure Functions, Shadowing Corrections and Charge Symmetry Violation

Comparison of structure functions measured in neutrino and charged lepton deep inelastic scattering can be used to test basic properties of parton distribution functions such as the validity of charge symmetry. Recent experiments indicate a substantial discrepancy between F ν 2 and F 2 in the region of small Bjorken-x. We discuss nuclear corrections and strange and anti strange quark effects an...
