Quasi-Elastic Electron Nucleus Scattering and the Correlated Fermi Gas

The study of neutrino-nucleus scattering processes is important for the successful execution of the entire new generation neutrino experiments. Quasielastic neutrino - nucleus scattering, which yields a final state consisting of a nucleon and charged lepton, make up a large part of the total neutrino cross-section in neutrino experiments. A significant source of uncertainty in the cross-section comes from limitations in our knowledge of nuclear effects in the scattering process. To this end, electron-nucleus scattering experiments play an imporant role in providing vital information to test and validate different nuclear models intended to be used in neutrino experiments. We present a cross-section calculation for the electron nuclues quasielastic scattering process using the Correlated Fermi Gas nuclear model characterized by a depleted Fermi gas region and a correlated high-momentum tail. This is carried out by identifying various transitions available for the nucleon inside the nucleus and the corresponding phase-space integrals. We discuss the comparison between cross-sections from this model with the available experimental data and the widely used Relativistic Fermi Gas (RFG) nuclear model.
