    "abstract": "A significant drop of the vector meson masses in nuclear matter is observed\nin a chiral SU(3) model due to the effects of the baryon Dirac sea. This is\ntaken into account through the summation of baryonic tadpole diagrams in the\nrelativistic Hartree approximation. The appreciable decrease of the in-medium\nvector meson masses is due to the vacuum polarisation effects from the nucleon\nsector and is not observed in the mean field approximation.",
