摘要：
Measurements of jet suppression in Pb+Pb Collisions by the ATLAS Collaboration are reported. The production of inclusive jet yields as a function of jet p(T), collision centrality and jet size parameter the central-to-peripheral ratio, R-CP. Jets are found to be suppressed in m R are measured and presented collisions by approximately a factor of two. The suppression is found to show almost no variation with jet P-T, and the R-CP is found to increase slighly with increasing R. Measurements of heavy quark energy loss are also presented using muons from semi-leptonic decays of heavy flavor hadrons. The maximal suppression is observed to be R-CP similar to 0.5 and shows no significant depedence on the muon p(T).
