New results on fully corrected dijet asymmetry in Pb+Pb collisions with ATLAS

The phenomenon of events containing highly asymmetric dijet pairs is one of the most striking results in heavy ion physics, providing the first direct observation of in-medium jet energy loss at the Large Hadron Collider. Detailed measurements of centrality-dependent dijet imbalance in 2.76 TeV Pb+Pb collisions using data collected by the ATLAS detector in the 2011 LHC heavy ion run are presented. The new analysis presents a measurement, fully corrected for detector effects to the particle level, of the centrality- and leading jet transverse momentum- ($p_\mathrm{T}$-) dependence of the dijet $p_\mathrm{T}$ balance distribution, compared to the analogous measurement in $pp$ collisions at the same center of mass energy.
