Subjet double-b quark tagging performance in 5 TeV pp collisions

Nearly collinear pairs of partons are sensitive to potential novel coherence effects in the parton energy loss process, which can be observed through measurements of jet substructure. This analysis presents a new measurement of jets containing a gluon that splits into a heavy quark pair, i.e., a hea...

description Nearly collinear pairs of partons are sensitive to potential novel coherence effects in the parton energy loss process, which can be observed through measurements of jet substructure. This analysis presents a new measurement of jets containing a gluon that splits into a heavy quark pair, i.e., a heavy-quark antenna. Such jets are identified by analyzing the groomed substructure of double b-tagged jets. The grooming procedure allows the identification of the hardest splitting process within the parton shower and is sensitive to the virtuality evolution of the parton. Detector performance studies are shown for 5.02 TeV simulations.
