The Hydrodynamic Description for the Pseudorapidity Distributions of the Charged Particles Produced in Pb–Pb Collisions at LHC Energy

The charged particles produced in nucleus-nucleus collisions are classified into two parts. One is from the hot and dense matter created in collisions with the evolution dominated by revised Landau hydrodynamics, and the other is from leading particles. The rapidity distributions of these two parts of the particles are presented, which are then compared with the experimental measurements carried out by a CERN-LHC-ALICE collaboration in Pb–Pb collisions at √s_NN=2.76 TeV. The theoretical results are consistent with the experimental data.
