We study hadronic jets that are tagged as heavy-flavoured, i.e. they contain either beauty or charm. In particular, we consider heavy-flavour jets that have been groomed with the Soft Drop algorithm. In order to achieve a deeper understanding of these objects, we apply resummed perturbation theory to jets initiated by a massive quark and we perform analytic calculations for two variables that characterise Soft Drop jets, namely the opening angle and the momentum fraction of the splitting that passes Soft Drop. We compare our findings to Monte Carlo simulations. Furthermore, we investigate the correlation between the Soft Drop energy fraction and alternative observables that aim to probe heavy-quark fragmentation functions.

  1. Heavy Quark Pair Energy Correlators: From Profiling Partonic Splittings to Probing Heavy-Flavor Fragmentation

    hep-ph 2025-08 conditional novelty 6.0 of 10

    Heavy-flavor energy-energy correlators isolate the gluon to heavy quark-antiquark splitting and are predicted to be sensitive to medium modifications and anisotropic quark-gluon plasma structure.

    CMS reports the first late-kT groomed splitting-angle distributions for prompt D0 jets at pT 100-120 GeV and finds suppression consistent with the charm dead cone, while soft-drop suppression appears driven by gluon s...

  3. Heavy Flavor Jet Substructure at Lepton Colliders

    hep-ph 2025-02 conditional novelty 4.0 of 10

    NLL-accurate predictions for heavy-flavor energy correlation functions and jet angularities in e+e- collisions show all tested Monte Carlo generators overestimate the dead-cone suppression.
