Description

We propose a new method for identifying and isolating Q anti Q+jet events through semileptonic decays of the Q anti 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 anti Q production (leading order in Q anti Q+jet production) in √(s)=14 TeV pp collisions at the LHC and discuss the feasibility of the measurement in heavy-ion collisions at √(sNN)=5.5 TeV.
