Multi-(K)over-bar nuclei and kaon condensation
Original language description
We extend previous relativistic mean-field (RMF) calculations of multi-(K) over bar nuclei, using vector boson fields with SU(3) PPV coupling constants and scalar boson fields constrained phenomenologically. For a given core nucleus, the resulting (K) over bar separation energy B-(K) over bar, as well as the associated nuclear and (K) over bar -meson densities, saturate with the number kappa of (K) over bar mesons for kappa>kappa(sat)similar to 10. Saturation appears robust against a wide range of variations, including the RMF nuclear model used and the type of boson fields mediating the strong interactions. Because B-(K) over bar generally does not exceed 200 MeV, it is argued that multi-(K) over bar nuclei do not compete with multihyperonic nuclei inproviding the ground state of strange hadronic configurations and that kaon condensation is unlikely to occur in strong-interaction self-bound strange hadronic matter.

Multi-Kbar jádra a kaonový kondenzát
Czech description
Byla počítána jádra s více antikaony. Bylo ukázáno,že jak separační energie antikaonu tak jaderné a kaonové hustoty saturují s rostoucím počtem antikaonů. Vznik kaonového kondenzátu v silně interagujících systémech je proto málo pravděpodobný.
