Extraction of dihadron-jet correlations with rigorous flow-background subtraction in a multiphase transport model
arXiv:1309.6744 · doi:10.1103/PhysRevC.87.024904
Abstract
Dihadron azimuthal correlations in Au+Au collisions at =200 GeV have been explored by using a multi-phase transport (AMPT) model. In order to obtain the contributions from jet-medium interactions, the combined harmonic flow background is subtracted from the raw dihadron correlation functions. The signals are compared in three associated transverse momentum () bins: 0.2-0.8 GeV/c, 0.8-1.4 GeV/c and 1.4-2.0 GeV/c from central to semi-peripheral geometries. The medium modifications are observed from changes in the signal shape and the relative jet contribution has been obtained within the change in the centrality from peripheral to central one. A strong dependence of the RMS width of jet correlation function is observed within the central geometry bin, i.e. 0-10.
