Microscopic description of deeply virtual Compton scattering off spin-0 nuclei

Abstract

We evaluate within a microscopic calculation the contributions of both coherent and incoherent deeply virtual Compton scattering from a spin-0 nucleus. The coherent contribution is obtained when the target nucleus recoils as a whole, whereas for incoherent scattering breakup configurations for the final nucleus into an outgoing nucleon and an $A\ensuremath{-}1$ system are considered. The two processes encode different characteristics of generalized parton distributions.
