Extracting Nuclear Transparency from p-A Cross sections

Abstract

We study nuclear structure effects on the transparency in high transverse momentum $(p,2p)$ and $(e,e^{\prime }p)$ reactions. We show that in the DWIA-eikonal approximation, even when correlations are included, one can get a factorized expression for the transparency. This depends only on the average nucleon density $\rho (r)$ and a correlation function. We develop a technique to include correlations in a Monte-Carlo Glauber type calculation. We compare calculations of $T$ using the eikonal formalism and a continuous density, with a Monte Carlo method based on discrete nucleons.
