摘要
Based on the knowledge of the QCD radiation pattern, observables to distinguish jets containing one and two b 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 b hadron with respect to the jet-into one discriminator. Their efficiencies, on the particle level, are estimated and found to improve the performance and the robustness of the observables in different momentum slices.
