Saturation in diffractive deep inelastic eA scattering

In this paper, we investigate the saturation physics in diffractive deep inelastic electron-ion scattering. We estimate the energy and nuclear dependence of the ratio sigma(diff)/sigma(tot) and predict the x(P) and beta behavior of the nuclear diffractive structure function F-2(D),((3))(A) (Q(2), beta, x(P)). Moreover, we analyze the ratio R-A1(diff),(A2) (Q(2), beta, x(P)) = F-2(D),((3))(A1) / F-2(D),((3))(A2), which probes the nuclear dependence of the structure of the pomeron. We show that saturation physics predicts that approximately 37% of the events observed at eRHIC should be diffractive.
