Large mass dilepton production from jet-dilepton conversion in the quark–gluon plasma

Abstract We calculate the production of large mass dileptons from the passage of jets passing through the quark–gluon plasma. Using the relativistic kinetic theory, we rigorously derive the production rate for the jet-dilepton conversion in the hot medium. The jet-dilepton conversion is compared with the thermal dilepton emission and the Drell–Yan process. The contribution of the jet-dilepton conversion is not prominent for all values of the invariant mass M , and the Drell–Yan process is found to dominate over the thermal dilepton emission and the jet-dilepton conversion for M > 2.5 GeV at RHIC. The jet-dilepton conversion is the dominant source of large mass dileptons in the range of 4 GeV M 10 GeV at LHC.
