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