Observation of a Centrality-Dependent Dijet Asymmetry in Lead-Lead Collisions at TeV with the ATLAS Detector at the LHC
Abstract
CERN-LHC. Measurement of the dijet asymmetry in lead-lead collisions at a centre-of mass energy of 2.76 TeV/nucleon. The data sample, taken during the run of 2010 with a total integrated luminosity of 1.7 mub-1 is collected with a minimum bias trigger. Jets are reconstructed using the anti-KT algorithm with R=0.4 with the underlying event background subtracted event-by-event. The leading jets are selected with maximum ET, with > 100 GeV for JET1 and > 25 GeV for JET2. The data are divided into 4 centrality regions and also compared with proton-proton data taken with the Atlas detector. DeltaPhi is the absolute difference in the azimuthal angles of the two leading jets. The Asymmetry is the difference in the transverse energies of the two leading jets divided by their sum for |DeltaPhi| < pi/2. Numerical values suppled by P Steinberg.
