Title: Dilepton-tagged QQ+Jet events at the LHC

Abstract

We propose a new method for identifying and isolating Q{bar Q} + jet events through semileptonic decays of the Q{bar Q} pair. Employing these decay dileptons to tag the jet in a specific kinematic region provides a clean signature of jets associated with heavy-quark production. The measurement, in both pp and heavy-ion collisions, is essential for addressing heavy-quark fragmentation in vacuum and in a dense medium. We present next-to-leading order calculations of Q{bar Q} production (leading order in Q{bar Q} jet production) in {radical}s = 14 TeV pp collisions at the LHC and discuss the feasibility of the measurement in heavy-ion collisions at {radical}s{sub NN} = 5.5 TeV.
