Glauber theory of final - state interactions in ( e , e ′ p ) scattering

A b s t r a c t We develop the Glauber theory description of final-state interaction (FSI) in quasielastic A(e, e ′ p) scattering. The important new effect is an interaction between the two tra-jectories which enter the calculation of FSI-distorted one-body density matrix and are connected with incoherent elastic rescatterings of the struck proton on spectator nucle-ons. We demonstrate that FSI distortions of the missing momentum distribution are large over the whole range of missing momenta. Important finding is that incoherent elastic rescatterings of the ejected proton lead to a strong quantum mechanical distortions of both the longitudinal and transverse missing momentum distributions. It is shown that allowance for finite longitudinal size of the interaction region for proton-nucleon collision neglected in the standard Glauber model drastically affects the theoretical predictions at high longitudinal missing momentum. We also find very large corrections to the missing momentum distribution calculated within the local-density approximation.
