摘      要：The dependence of charged particle pseudorapidity distributions on centrality in Pb-Pb collisions at√sNN=2.76 TeV is studied by using a multi-source thermal model(previously the two-cylinder model or the multi-source ideal gas model).The rapidity shifts of the interacting system are almost independent of the centrality *** contribution of leading nucleons increases with the increasing centrality class(percent).The calculated results are compared and found to be in agreement with the experimental data of the ATLAS,ALICE,and CMS collaborations.
