摘要：

The dilepton production is investigated in proton-nucleus collisions in the forward region using the Color Glass Condensate approach. The transverse momentum distribution (p(T)), more precisely the low p(T) region, where the saturation effects are expected to increase, is analyzed. The ratio between proton-nucleus and proton-proton differential cross section for RHIC and LHC energies is evaluated, showing the effects of saturation at small p(T), and presenting a suppression of the Cronin type peak at moderate p(T). These features indicate the dilepton as a most suitable probe to study the properties of the saturated regime and the Cronin effect.
