Contribution

It introduces a novel non-factorized, realistic approach to analyze the process, incorporating rescattering effects with no adjustable parameters.

Findings

Left-right asymmetry depends on final state interactions.

Factorization approximation breaks down at high missing momentum.

Results agree with recent JLab experimental data.

Abstract

The exclusive process 3He(e,e'p)2H has been analyzed by a non-factorized and parameter-free approach based upon realistic few-body wave functions corresponding to the $AV18$ interaction and treating the rescattering of the struck nucleon within a generalized eikonal approximation. The results of our calculations, compared with recent JLab experimental data, show that the left-right asymmetry exhibits a clear dependence upon the final state interaction demonstrating the breaking down of the factorization approximation at "negative" and large (> 300 MeV/c) values of the missing momentum.
