Nuclear model effects in neutrino-nucleus quasielastic scattering
نویسنده
چکیده
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 measurements of the axial strange form-factor of the nucleon are investigated.

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 effects on lepton polarization in charged-current quasielastic neutrino scattering
We use a correlated local Fermi gas (LFG) model, which accounts also for long distance corrections of the RPA type and final-state interactions, to compute the polarization of the final lepton in charged-current quasielastic neutrino scattering. The present model has been successfully used in recent studies of inclusive neutrino nucleus processes and muon capture. We investigate the relevance o...

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 کاملNeutrino nucleus cross sections
We present the results of our calculation which has been performed to study the nuclear effects in the quasielastic, inelastic and deep inelastic scattering of neutrinos(antineutrinos) from nuclear targets. These calculations are done in the local density approximation. We take into account the effect of Pauli blocking, Fermi motion, Coulomb effect, renormalization of weak transition strengths ...
