Saturation in diffractive deep inelastic eA scattering

Original · EN

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 σdiff/σtot and predict the x and β behavior of the nuclear diffractive structure function F₂,ₐᵈ⁽³⁾(Q², β, xIP). Moreover, we analyze the ratio Rdiffₐ₁,ₐ₂(Q², β, xIP) = F₂,ₐ₁ ᵈ⁽³⁾/F₂,ₐ₂ ᵈ⁽³⁾, 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.
