Abstract
The ATLAS experiment at the LHC has measured the production of charged hadrons in PbPb collisions at sqrt{s_{NN}}=2.76TeV as a function of transverse momentum (pT) in the range 0.5-150GeV and in the pseudorapidity range of +/- 2.5. The charged particle spectra measured at different pseudorapidities are consistent with each other within the statistical and systematic uncertainties. The ratio of the central to peripheral events measured in the 0-5% and 60-80% centrality classes and scaled by the number of binary nucleon-nucleon collisions shows a suppression of charged hadrons by a factor of 5 at pT=7GeV. At higher pT the ratio increases with transverse momentum up to the highest measured pT.
