N2 - We report on recent relativistic mean-field calculations of multi-K̄ nuclei1,2 which were performed fully and self-consistently across the periodic table. The K̄ separation energy BK̄ as well as the nuclear and K̄-meson densities were found to saturate with the number of antikaons in the nuclear medium. Saturation appears robust against a wide range of variations, including the nuclear model used and the type of boson fields mediating the strong interactions. In addition, we have explored properties of kaonic hypernuclei - strange systems made of nucleons, hyperons and K- mesons. We observed saturation also in these objects. Since the K̄ separation energy BK̄ does not exceed 200 MeV, multi-K̄ nuclei lie energetically well above multi-hyperonic nuclei and it is unlikely that kaon condensation could occur in strong-interaction self-bound hadronic matter.
