We consider propagation of heavy quarks in QCD matter. Because of large quark mass, the radiative quark energy loss appears to be qualitatively different from that of light quarks at all energies of practical importance. Finite quark mass effects lead to an in-medium enhancement of the heavy-to-light D/\pi ratio at moderately large (5--10 GeV) transverse momenta. For hot QCD matter a large enhancement is expected, whose magnitude and shape are exponentially sensitive to the density of colour charges in the medium.

  1. Medium-induced modification of azimuthal correlations of electrons from heavy-flavor hadron decays with charged particles in Pb-Pb collisions at $\sqrt{s_{\rm{NN}} = 5.02}$ TeV

    nucl-ex 2025-07 accept novelty 6.0 of 10

    First Pb-Pb measurement of heavy-flavor electron-charged particle azimuthal correlations shows a near-side low-pT enhancement hint (1.27 sigma) and an away-side high-pT suppression (2.5 sigma) in central collisions.

  2. Investigation of the performance of a GNN-based b-jet tagging method in heavy-ion collisions

    physics.data-an 2025-06 conditional novelty 6.0 of 10

    A GNN-based b-jet tagger adapted from ATLAS's GN1 retains good performance on simulated Pb-Pb background when retrained per centrality, despite degradation when applied out-of-the-box.

  3. Energy Loss of a Heavy Quark in a Collisional Quark-Gluon Plasma

    hep-ph 2025-12 unverdicted novelty 5.0 of 10

    Including thermal parton collisions via the BGK kernel increases the collisional energy loss of a heavy quark in QGP by ~8% at large velocities for α_s=0.3 compared to the collisionless limit.

  4. Impact of momentum-dependent drag coefficient on energy loss of charm and bottom quarks in QGP

    hep-ph 2025-02 unverdicted novelty 3.0 of 10

    Extends drag coefficient with momentum-dependent polynomials and evolves charm/bottom distributions via Fokker-Planck to compute R_AA in 5.02 TeV Pb-Pb collisions for comparison to ALICE/ATLAS data.
