Exclusive Electro-Disintegration of 3He at High Q2: I. Generalized Eikonal Approximation

TL;DR

This paper presents a theoretical framework using the generalized eikonal approximation to analyze high Q^2 exclusive electro-disintegration of helium-3, enabling detailed study of nucleon interactions and short-range correlations.

Contribution

It introduces the GEA method for calculating final state interactions that accounts for finite nucleon momenta, improving upon traditional Glauber approaches.

Findings

GEA allows self-consistent analysis of short-range correlations.

The approach explicitly includes Fermi motion of recoil nucleons.

It provides a new way to study nucleon dynamics in high Q^2 processes.

Abstract

We develop a theoretical framework for calculation of high $Q^2$ exclusive electro-disintegration of A=3 systems. The main result of this work is the calculation of the final state interaction of the struck energetic nucleon with recoil nucleons within the generalized eikonal approximation (GEA) which allows us to account for the finite and relatively large momenta of the bound nucleons in the nucleus. The important advantage of this approach is the possibility to study in a self-consistent way the short range correlations in nuclei. This is due to the fact that GEA does not require a stationary condition for recoil nucleons as conventional Glauber approximation does. As a result GEA treats explicitly the Fermi motion of recoil nucleons in the nucleus.
