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.
