description | The ATLAS detector provides excellent capabilities for reconstructing jets in PbPb collisions with highly segmented calorimeters covering the pseudo-rapidity interval $|eta|<5$. Jet measurements at the LHC are expected to provide new insight on the mechanisms responsible for the quenching of jets in the hot, dense medium created in nucleus-nucleus collisions. In the Fall 2010 LHC Pb+Pb run at $sqrt{s_{NN}} = 2.76$~TeV, ATLAS recorded approximately 10~${mu mathrm{b}^{-1}}$ of Pb+Pb collisions. 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. |
