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

TL;DR

This paper calculates large mass dilepton production from jet interactions in quark-gluon plasma, comparing it with other sources, and finds it dominant in certain mass ranges at LHC energies.

Contribution

It provides a rigorous derivation of jet-dilepton conversion rates using relativistic kinetic theory and compares its significance with thermal and Drell-Yan dileptons.

Findings

Jet-dilepton conversion is not dominant at all masses.

Drell-Yan process dominates for M > 2.5 GeV at RHIC.

Jet-dilepton conversion is the main source for 4-10 GeV at LHC.

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.
