Non-factorized calculation of the process 3He(e,e'p)pn at medium energies

TL;DR

This paper presents a non-factorized, parameter-free calculation of the 3He(e,e'p)pn process at medium energies, accurately matching experimental data and highlighting the dominant role of single rescattering in specific kinematic regions.

Contribution

It introduces a novel non-factorized approach using realistic wave functions and generalized eikonal approximation for the first time in this context.

Findings

Good agreement with JLab experimental data.

Rescattering dominated by single nucleon interactions.

Validates nucleon-nucleon correlation predictions.

Abstract

The cross section and the transverse-longitudinal asymmetry A_{TL} of the three-body-break-up (3BBU) process 3He(e,e'p)pn have been calculated by a non-factorized and parameter-free approach based upon realistic few-body wave functions corresponding to the $AV18$ interaction, treating the rescattering of the struck nucleon within a generalized eikonal approximation. The results of calculations exhibit a good agreement with recent JLab experimental data and show that the Final State Interaction (FSI) of the struck proton in the region of missing momentum 300 < p_m < 600 MeV/c and removal energy E_m > p_m^2/4m_N is dominated by single nucleon rescattering, in agreement with nucleon-nucleon correlation predictions.
