Dijet asymmetry in Pb + Pb collisions at √sNN = 2.76 TeV within a multiphase transport model.

Within a multiphase transport (AMPT) model, dijet asymmetry is studied in Pb + Pb collisions at √sNN = 2.76 TeV. It is found that a large dijet asymmetry (Aj) is produced by strong interactions between jets and partonic matter. It is demonstrated that hadronization and final-state hadronic rescatterings have little effect on Aj. The final Aj is found to be driven by both initial Aj and partonic jet energy loss, which is consistent with an increasing jet energy loss in a hot and strongly interacting partonic medium in more central Pb + Pb collisions.
