Distinguishing b-quark and gluon jets with a tagged b-hadron

High Energy Physics - Phenomenology 2016-03-23 v1

Abstract

Based on the knowledge of the QCD radiation pattern, observables to distinguish jets containing one and two bb-hadrons are discussed. A simple method is used to combine pairs of the most sensitive observables, girth, number of charged tracks and the energy or momentum fraction of the leading bb-hadron with respect to the jet, into one discriminator. Their efficiencies, on particle level, are estimated and found to improve the performance and the robustness of the observables in different momentum slices.
