AbstractMeasurements of inclusive jet suppression in Pb + Pb collions at sNN=2.76 TeV with the ATLAS detector are reported. The centrality, pT and jet size dependence of the central-to-peripheral ratio, RCP, is presented. The results indicate that jets are suppressed by approximately a factor of two in the most central collisions, and a significant dependence on the jet size is observed. The path length dependence of jet quenching is studied through measurements of inclusive jet suppression as a function of angle with respect to the event plane. The azimuthal modulation of the jet yield is quantified by its second Fourier coefficent, ν2, which is significant in all pT and centrality ranges presented.
