We propose a new method for identifying and isolating
events through semileptonic decays of the
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
production (leading order in
production) in
TeV pp collisions at the LHC and discuss the feasibility of the measurement in heavy-ion collisions at
TeV.
