Nuclear $\text{C}(e,e'p)$ Transparencies in a Relativistic Glauber Model

TL;DR

This paper uses a relativistic Glauber model to analyze nuclear $^{12}$C$(e,e'p)$ transparencies, comparing calculations with recent Jefferson Laboratory data and examining color transparency effects.

Contribution

It introduces shell-separated transparency calculations within a relativistic Glauber framework and assesses color transparency signals in $^{12}$C$(e,e'p)$ reactions.

Findings

$p$-shell nucleons are 75% more transparent than $s$-shell nucleons.

No clear evidence of color transparency onset in the data.

Calculations align with experimental data without requiring color transparency effects.

Abstract

In light of the recent Jefferson Laboratory (JLab) data for the nuclear $^{12}\text{C}(e,e'p)$ transparencies, calculations, obtained in a relativistic multiple scattering Glauber approximation, are discussed. The shell-separated $^{12}$C transparencies are shown and it is concluded that the $p$-shell nucleons are 75\% more transparent than the $s$-shell ones. The presented comparisons between the calculations made here and the current $^{12}\text{C}(e,e'p)$ data show no clear indication for the onset of color transparency when implemented within the color diffusion model with standard parameters.
