Description
In high energy electron-ion colliders, a new way to probe nucleon structure becomes available through diffractive reactions, where the incident particle produces a very energetic almost forward particle. QCD describes these reactions as due to the exchange of a Pomeron which may be perturbatively described as a dressed two-gluon state, provided a hard scale allows the factorization of the amplitude. In this talk, we consider two diffractive exclusive processes that give access to hadronic structure in terms of the generalized parton distributions (GPDs): 1) electroproduction of a forward
