Correlation Effects in the Final-State Interaction for Quasielastic $(e,e^{\prime }p)$ Scattering

Abstract

Color transparency predicts that, in $(e,e^{\prime }p)$ reactions at large $Q^2$, the final-state interaction becomes weaker than the reference value predicted from the free-nucleon cross section. This reference value is usually evaluated in the dilute-gas approximation to Glauber's multiple-scattering theory. We derive the leading-order correction taking into account two-body correlations. Large cancellations are found so that the overall correlation effect is small.
