| Abstract | The transverse-momentum and pseudorapidity dependences of partonic Machlike shock wave have been studied by using a multiphase transport model with both partonic and hadronic interactions. The splitting parameter D, i.e., half distance between two splitting peaks on away side in di-hadron azimuthal angular (Delta phi) correlations, slightly increases with the transverse momentum of associated hadrons (p(T)(assoc)), which is consistent with preliminary experimental trend, owing to different interaction-lengths/numbers between wave partons and medium in strong parton cascade. However, the splitting parameter D as a function of pseudorapidity of associated hadrons (eta(assoc)), stays flat in the mid-pseudorapidity region and rapidly drops in the high-pseudorapidity region, which is a result of different violent degrees of jet-medium interactions in the medium that has different energy densities in the longitudinal direction. It is proposed that the research on the properties of Machlike correlation can shed light on the knowledge of both partonic and hadronic interactions at RHIC. |
