Nuclear model effects in Charged Current neutrino–nucleus quasielastic scattering
The quasielastic scattering of muon neutrinos on oxygen 16 and carbon 12 targets is studied for neutrino energies between 200 MeV and 1 GeV, using the relativistic Fermi gas and a relativistic shell model. Final state interactions are included within the distorted wave impulse approximation. The different models are then employed to compute the inclusive charged–current quasielastic cross secti...
متن کاملNuclear model effects in neutrino-nucleus quasielastic scattering
Nuclear model effects in neutrino-nucleus quasielastic scattering are studied within the distorted wave impulse approximation, using a relativistic shell model to describe the nucleus, and comparing it with the relativistic Fermi gas. Both charged-current and neutral-current processes are considered and, for the neutral-current case, the uncertainties that nuclear effects may introduce in measu...
متن کاملRelativistic nuclear structure effects in quasielastic neutrino scattering.
Charged-current cross sections are calculated for quasielastic neutrino and antineutrino scattering using a relativistic meson-nucleon model. We examine how nuclear-structure effects, such as relativistic random-phaseapproximation (RPA) corrections and momentum-dependent nucleon selfenergies, influence the extraction of the axial form factor of the nucleon. RPA corrections are important only at...
متن کاملModelling nuclear effects in neutrino interactions in 1 GeV region
Description of ∆ excitation region in neutrinonucleus interactions is the most problematic ingredient in Monte Carlo codes [1]. Experiments provide cross sections with a precision ∼ 25% [2,3]. MC implementations are based on a combination of Rein-Sehgal pion production model [4] with Fermi gas model with different level of sophistication in kinematical assumptions. The basic dynamical rule is a...
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...
