| 英文摘要 | Jet production in pbpb collisions at a nucleon-nucleon center-of-mass energy of 2.76 tev was studied with the compact muon solenoid (cms) detector at the lhc, using a data sample corresponding to an integrated luminosity of 6.7 mu b(-1). jets are reconstructed using the energy deposited in the cms calorimeters and studied as a function of collision centrality. with increasing collision centrality, a striking imbalance in dijet transverse momentum is observed, consistent with jet quenching. the observed effect extends from the lower cutoff used in this study (jet p(t) = 120 gev/c) up to the statistical limit of the available data sample (jet p(t) approximate to 210 gev/c). correlations of charged particle tracks with jets indicate that the momentum imbalance is accompanied by a softening of the fragmentation pattern of the second most energetic, away-side jet. the dijet momentum balance is recovered when integrating low transverse momentum particles distributed over a wide angular range relative to the direction of the away-side jet. |
