Observation of a centrality-dependent dijet asymmetry in lead-lead collisions at √sNN =2.76 Tev with the ATLAS detector at the LHC
Physical Review Letters 105:25 (2010)
Abstract:
By using the ATLAS detector, observations have been made of a centrality-dependent dijet asymmetry in the collisions of lead ions at the Large Hadron Collider. In a sample of lead-lead events with a per-nucleon center of mass energy of 2.76 TeV, selected with a minimum bias trigger, jets are reconstructed in fine-grained, longitudinally segmented electromagnetic and hadronic calorimeters. The transverse energies of dijets in opposite hemispheres are observed to become systematically more unbalanced with increasing event centrality leading to a large number of events which contain highly asymmetric dijets. This is the first observation of an enhancement of events with such large dijet asymmetries, not observed in proton-proton collisions, which may point to an interpretation in terms of strong jet energy loss in a hot, dense medium.© 2010 CERN, for the ATLAS Collaboration.Erratum: Scaled momentum spectra in deep inelastic scattering at HERA (Journal of High Energy Physics (2010) 06 (009))
