Jet probes of √{s_{{ NN}}}= 2.76 TeV Pb+Pb collisions with the ATLAS detector

The ATLAS detector with highly segmented calorimeters covering the pseudo-rapidity interval |η| < 5 provides excellent capabilities for reconstructing jets in Pb+Pb collisions. In the Fall 2010 LHC Pb+Pb run at TeV, ATLAS recorded about 10 μb−1 of Pb+Pb collisions. Using approximately 7 μb−1 from this data set, jets were reconstructed using the anti-kt algorithm for two jet size parameters, R = 0.2 and R = 0.4, and using a per-event estimation and subtraction of the underlying event. New, preliminary ATLAS measurements obtained from this analysis of single jet spectra and jet central-to-peripheral ratios (RCP), jet charged particle fragmentation distributions, and dijet asymmetry distributions for R = 0.2 jets are presented.
