Nuclear DVCS at small-x using the color dipole phenomenology

Abstract

Using the high energy color dipole formalism, we study the coherent and incoherent nuclear DVCS process in the small-x regime. We consider simple models for the elementary dipole-hadron scattering amplitude that captures main features of the dependence on atomic number A, on energy and on momentum transfer t. Using the obtained amplitudes we make predictions for the nuclear DVCS cross section at photon level in the collider kinematics.
