Abstract In a previous paper ( arXiv:1011.1895 ), we showed that saturation models, constrained by e + p HERA data on inclusive and diffractive cross-sections, are in good agreement with p + p data at LHC in the soft sector. Particularly impressive was the agreement of saturation models with the multiplicity distribution as a function of n ch . . In this Letter, we extend these studies further and consider the agreement of these models with data on bulk distributions in A + A collisions. We compare our results to data on central and forward particle production in d + Au collisions at RHIC and make predictions for inclusive distributions in p + Pb collisions at the LHC.
