Relativistic descriptions of final-state interactions in charged-current quasielastic neutrino-nucleus scattering at MiniBooNE kinematics

TL;DR

This paper compares two relativistic models of final-state interactions in charged-current quasielastic neutrino-nucleus scattering with MiniBooNE data, showing that the RGF model accurately reproduces total cross-sections without adjusting the axial mass.

Contribution

It introduces and compares two relativistic models for final-state interactions, demonstrating the effectiveness of the RGF model in describing experimental data.

Findings

RGF model accurately reproduces MiniBooNE total cross-sections.

No modification of nucleon axial mass needed for RGF model.

Both models provide insights into relativistic descriptions of neutrino-nucleus interactions.

Abstract

The results of two relativistic models with different descriptions of the final-state interactions are compared with the MiniBooNE data of charged-current quasielastic cross sections. The relativistic mean field model uses the same potential for the bound and ejected nucleon wave functions. In the relativistic Green's function (RGF) model the final-state interactions are described in the inclusive scattering consistently with the exclusive scattering using the same complex optical potential. The RGF results describe the experimental data for total cross-sections without the need to modify the nucleon axial mass.
