Abstract:
In this paper, we investigate dilepton production in heavy-ion collisions from 8 to 200 GeV with a focus on the competition between the thermal quark-gluon plasma (QGP) radiation and the semi-leptonic decays from correlated D-meson pairs. As a tool, we employ the parton-hadron string dynamics (PHSD) transport approach incorporating a fully microscopic treatment of the charm dynamics and their semi-leptonic decays. We find that the dileptons from correlated D-meson decays dominate the thermal radiation from the QGP in central Pb + Pb collisions at the intermediate masses (1.2 GeV < M < 3 GeV) for while for decays to the intermediate mass dilepton spectra is subleading such that one should observe a rather clear signal from the QGP radiation, which is dominated by the annihilation channel qq -> gamma*.
