Signatures of the Color Glass Condensate in electron ion collisions

In previous works we have studied gluon saturation effects in deep inelastic electron-ion scattering. Among other observables we have calculated the energy and nuclear dependence of the ratio σdiff/σtot and also the behavior of the ratio . In order to perform our analysis we had to make some assumptions concerning the nuclear dependence of the saturation scale. In the present contribution we check whether our early conclusions still hold for a different dependence of the saturation scale on the atomic number.
