【 摘 要 】

Within a multi-phase transport (AMPT) model, the transverse momentum asymmetries for -jet and dijet are studied in Pb+Pb collisions atSNN = 2.76 TeV. A large asymmetry is produced by strong interactions between jets and partonic matter. It is demonstrated that hadronization and hadronic rescatterings have little effects on the formed asymmetries. The asymmetry evolution function discloses that final asymmetry is driven by both initial asymmetry and partonic jet energy loss. The γjet imbalance ratio, xjγ is sensitive to both production position and passing direction of γjet, which could enable a detail tomographic study on the formed partonic matter by selecting xjγ.
