| 摘要: | 摘要： An analysis of dijet events in PbPb and pp collisions is performed to explore the properties of energy loss by partons traveling in a quark-gluon plasma. Data are collected at a nucleon-nucleon center-of-mass energy of 2.76 TeV at the LHC. The distribution of transverse momentum (p sub(T)) surrounding dijet systems is measured by selecting charged particles in different ranges of p sub(T) and at different angular cones of pseudorapidity and azimuth. The measurement is performed as a function of centrality of the PbPb collisions, the p sub(T) asymmetry of the jets in the dijet pair, and the distance parameter R used in the anti-k sub(T) jet clustering algorithm. In events with unbalanced dijets, PbPb collisions show an enhanced multiplicity in the hemisphere of the subleading jet, with the p sub(T) imbalance compensated by an excess of low-p sub(T) particles at large angles from the jet axes.
