At the LHC the overlap of minimum bias events and the jet energy deposits in a calorimeter causes a degradation in the dijet mass resolution. Guided by QCD, a judicious set of cuts can be developed to mitigate this degradation.

The formation of jets in black hole accretion systems is a long-standing problem. It has been proposed that a jet can be formed by extracting the rotation energy of the black hole ("BZ-jet") or the accretion flow ("disk-jet"). While both…
