Abstract

The ATLAS experiment at the LHC measures the charged particle spectra and the nuclear modification factor in Pb+Pb collisions at the \√s_NN=2.76TeV in a transverse momentum range up to 30 GeV and a pseudorapidity range up to |\η| < 2.5. The measurement reveals the strong suppression of charged hadron production in the most central collisions at a p_T of about 7 GeV. A suppression of more than a factor of 2 is also measured at the upper edge of the analyzed p_T range. The suppression does not show any strong \η dependence.
