Jet quenching and heavy flavor production with the ATLAS detector

Measurements of inclusive jet and heavy quark jet suppression in relativistic heavy ion collisions are presented. The measurements were performed using Pb+Pb collisions at $sqrt{s_{NN}}=2.76$~TeV recorded with the ATLAS detector at the LHC during the 2010 Pb ion run. Results are obtained using calorimetrically reconstructed jets using the anti-kt algorithm with a per-event background subtraction procedure. Measurements of the single inclusive jet spectrum with jet radius parameters R = 0.2, 0.3, 0.4 and 0.5, are presented. The spectra are unfolded to correct for the finite energy resolution introduced by both detector effects and underlying event fluctuations. Single jet production, through the central-to-peripheral ratio RCP, is presented as a function of jet pT, centrality and jet radius. Measurements of the single inclusive muons are also presented over the range 4 < pT < 14 GeV, where the production is dominated by the semi-leptonic decays of open heavy flavor hadrons. The muon spectra and RCP are presented as a function of pT and centrality, which provide sensitivity to the quenching of heavy quarks.
