High momentum dilepton production from jets in a quark gluon plasma

摘要: We discuss the emission of high momentum lepton pairs (${p}_{T}g4$ GeV) in central Au+Au collisions at RHIC ($\sqrt{{s}_{\mathit{NN}}}=200$ and Pb+Pb LHC ($\sqrt{{s}_{\mathit{NN}}}=5500$ GeV). Yields dileptons produced through interactions jets with thermal partons have been calculated, next-to-leading order corrections hard loop (HTL) resummation. They are compared to dilepton Drell-Yan process. A complete leading treatment jet energy loss has included. Jet-plasma found dominate over for all values invariant mass $M$. is dominant source $Mg3$ GeV RHIC, after background from heavy quark decays subtracted. At LHC, range $Ml7$ dominated by jet-plasma interactions. Effects on turn out be weak, but non-negligible, reducing yield low-mass about $30%$.
