AbstractIt has been observed a "Mach-like" structure of di-hadron azimuthal correlations in Au + Au central collisions at root(NN)-N-S = 200 GeV in the framework of a multi-phase transport model (AMPT) with both partonic and hadronic interactions. In this paper, we will show centrality, transverse momentum (p(T)) and pseudorapidity (eta) dependences of "Mach-like" structure. The splitting parameter D, i.e. half distance between two splitting peaks on away side, decreases with the impact parameter b (corresponding to centrality) and slightly increases with transverse momentum of associated hadrons (pT(p(T)(assoc)), which from string melting AMPT version is consistent with experimental results. And the splitting parameter D is flat in mid-pseudorapidity region and rapidly decreases with the increasing of high-vertical bar eta(assoc)vertical bar.
