Title: Measurements of the nuclear modification factor for jets in Pb + Pb collisions at s NN = 2.76 TeV with the ATLAS detector

Abstract

The measurements of inclusive jet production are performed in pp and Pb+Pb collisions at √ sNN = 2.76 TeV with the ATLAS detector at the LHC, corresponding to integrated luminosities of 4.0 and 0.14 nb -1, respectively. The jets are identified with the anti-kt algorithm with R = 0.4, and the spectra are measured over the kinematic range of jet transverse momentum 32T<500 GeV and absolute rapidity |y|<2.1 and as a function of collision centrality. The nuclear modification factor R AA is evaluated, and jets are found to be suppressed by approximately a factor of 2 in central collisions compared to pp collisions. The R AA shows a slight increase with p T and no significant variation with rapidity.
