Net-Baryon and Net-Kaon Rapidity Distributions in Ultrarelativistic Heavy-Ion Collisions

Abstract

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.
