摘要：

Considering the magnetic field response of the QGP medium, we perform a systematical study of the chiral magnetic effect (CME), and make a comparison with the experimental results for the background-subtracted correlator H at the energies of the RHIC Beam Energy Scan (BES) and the LHC energy. The CME signals from our computations show a centrality trend and beam energy dependence that are qualitatively consistent with the experimental measurements of the charge dependent correlations. The time evolution of the chiral electromagnetic current at the RHIC and LHC energies is systematically studied. The dependence of the time-integrated current signal on the beam energy root s with different centralities is investigated. Our phenomenological analysis shows that the time-integrated electromagnetic current is maximal near the collision energy root s approximate to 39 GeV. The qualitative trend of the induced electromagnetic current is in agreement with the CME experimental results at the RHIC and LHC energies.
