Abstract 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 class. The 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.
