摘　　要：In this paper,the gluon distribution is extracted from the KLR-AdS/CFT saturation model and used to investigate net-baryon and net-kaon rapidity distributions in ultrarelativistic heavy-ion collisions.With the same parameters of the saturation model fitting to HERA data and an χ 2 analysis of the overall constant C,the theoretical results are in good agreement with RHIC data in Au+Au collisions at √ s = 0.2 TeV.Then,we present the predictive results for net-baryon rapidity distributions in central Pb+Pb collisions at LHC energies of √ s = 2.76,3.94,and 5.52 TeV,and give the corresponding values of dN/dy for net-baryon at y = 0.
