A significant drop of the vector meson masses in nuclear matter is observed in a chiral SU(3) model due to the effects of the baryon Dirac sea. This is taken into account through the summation of baryonic tadpole diagrams in the relativistic Hartree approximation. The appreciable decrease of the in-medium vector meson masses is due to the vacuum polarisation effects from the nucleon sector and is not observed in the mean field approximation.

  1. Towards compressed baryonic matter densities: D meson diffusion

    nucl-th 2026-07 conditional novelty 4.0

    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.
