A fluid-dynamic approach to the diffusion of heavy quarks in the quark--gluon plasma (QGP) is presented. Specifically, we analyze the Fokker-Planck equation for the momentum transport of heavy quarks from a fluid perspective and use a mapping to second-order fluid-dynamics to determine conductivities and relaxation times governing their spatial diffusion. By investigating the relation between the two approaches, we provide new insights concerning the level of local thermalization of charm and bottom quarks inside the expanding QGP. Our results indicate that a fluid-dynamic description of diffusion is feasible for charm quarks at least for the latest stages of the fireball evolution.

  1. Out-of-equilibrium contributions to charm hadrons in a fluid-dynamic approach

    hep-ph 2025-10 conditional novelty 6.0 of 10

    Out-of-equilibrium corrections at initialization and freeze-out make computed charm-hadron yields independent of the charm diffusion coefficient and define the reliable transverse-momentum range.

  2. Initial-State Charge Density Predicts Final-State Net Charge Flow in Heavy-Ion Collisions

    nucl-th 2025-05 conditional novelty 6.0 of 10

    Initial baryon density, through a charge-odd cumulant estimator with a fitted coupling, predicts final net-proton elliptic flow in event-by-event hydrodynamic simulations.

  3. Towards compressed baryonic matter densities: D meson diffusion

    nucl-th 2026-07 conditional novelty 4.0 of 10

    Using relaxation-time kinetic theory with a chiral hadronic model, the authors estimate that D meson spatial diffusion in dense nuclear matter decreases rapidly in a dilute-gas regime and mildly in a degenerate-gas regime.
