摘要
We present a study of charged particle pseudorapidity density distribution over a broad range of pseudorapidity and centrality in Pb+Pb collisions at root s(NN) = 2.76 TeV with the ATLAS detector at the LHC. The global shapes of multiplicity density distributions over four units of pseudorapidity from -2 to 2 are presented. Centrality and collision energy dependence of mid-rapidity density per participating nucleon pair is shown and compared to results of previous measurements.
