Kaon condensation and multi-strange matter

Abstract

We report on dynamical calculations of multi- K ¯ hypernuclei, which were performed by adding K ¯ mesons to particle-stable configurations of nucleons, Λ and Ξ hyperons. The K ¯ separation energy as well as the baryonic densities saturate with the number of antikaons. We demonstrate that the saturation is a robust feature of multi- K ¯ hypernuclei. Because the K ¯ separation energy B K ¯ does not exceed 200 MeV, we conclude that kaon condensation is unlikely to occur in finite strong-interaction self-bound { N , Λ , Ξ } strange hadronic systems.
