Findings

RGF and RMF models redistribute strength while conserving flux

Both models produce results consistent with experimental data

Comparison reveals differences in final-state interaction treatments

Abstract

Models developed for the exclusive and inclusive quasielastic (QE) electron-nucleus scattering have been extended to QE neutrino-nucleus scattering. Different descriptions of final-state interactions (FSI) are compared. For the inclusive electron scattering the relativistic Green's function model (RGF) is compared with a model based on the use of relativistic purely real mean field (RMF) potentials in the final state. Both approaches lead to a redistribution of the strength but conserving the total flux. Results for electron and neutrino scattering are presented and discussed in different conditions and kinematics. The results of the RGF and RMF models are compared with the double-differential charged-current QE neutrino cross sections recently measured by the MiniBooNE collaboration using a carbon target.
