TL;DR

This paper compares relativistic models of final-state interactions in quasielastic electron and neutrino scattering, analyzing their effectiveness against recent experimental data to improve understanding of nuclear responses.

Contribution

It introduces and compares relativistic Green's function and mean field models for FSI in QE scattering, providing insights into their accuracy against experimental measurements.

Findings

RGF and RMF models show different predictions for FSI effects.

Both models are evaluated against MiniBooNE CCQE data.

Results highlight the importance of relativistic treatments in nuclear scattering models.

Abstract

Models developed within the framework of the relativistic impulse approximation for quasielastic (QE) electron and neutrino-nucleus scattering are discussed. Different descriptions of final-state interactions (FSI) in the inclusive scattering are compared: the relativistic Green's function (RGF) and the relativistic mean field (RMF).The results of the models are compared with the recently measured double-differential charged-current QE (CCQE) neutrino MiniBooNE cross sections.
