Abstract (data abstract)
CERN-LHC. Decomposing transverse momentum balance contributions for quenched jets in PbPb collisions at 2.76 TeV with CMS Interactions between jets and the quark-gluon plasma produced in heavy ion collisions are studied via the angular distributions of summed charged-particle transverse momenta (pT) with respect to both the leading and subleading jet axes in high-pT dijet events. The contributions of charged particles in different momentum ranges to the overall event pT balance are decomposed into short-range jet peaks and a long-range azimuthal asymmetry in charged-particle pT. The results for PbPb collisions are compared to those in pp collisions using data collected in 2011 and 2013, at collision energy 2.76 TeV with integrated luminosities of 166 inverse microbarns and 5.3 inverse picobarns, respectively, by the CMS experiment at the LHC. Measurements are presented as functions of PbPb collision centrality, charged-particle pT, relative azimuth, and radial distance from the jet axis for balanced and unbalanced dijets. Dijet events are characterized by asymmetry parameter Aj = (pT1 - pT2)/(pT1 + pT2), where pT1 = transverse momentum of the leading (highest-pT) jet and pT2 = transverse momentum of the subleading (second-highest-pT) jet. The sample is divided into two asymmetry classes--more balanced dijets for which Aj < 0.22 (52% of the PbPb sample and 67% of the pp sample), and more unbalanced dijets for which Aj > 0.22.
