Quasielastic Lepton-Nucleus Scattering and the Correlated Fermi Gas Model

Abstract: The study of neutrino-nucleus scattering processes is important for the new generation neutrino experiments for better understanding of the neutrino oscillation phenomenon. A significant source of uncertainty in the cross-section comes from limitations in our knowledge of nucleon and nuclear effects in the scattering process. Here we present a fully analytic implementation of the Correlated Fermi Gas nuclear model for the quasi-elastic lepton nucleus scattering. The implementation is then used to separately compare form factor effects and nuclear model effects, specifically the Relativistic Fermi Gas nuclear model, for both electron-carbon and neutrino-carbon scattering data.
