Multi-K hypernuclei

الأصل · EN

Relativistic mean field calculations of multi-K hypernuclei are performed by adding K- mesons to particle-stable configurations of nucleons, Λ and Ξ hyperons. For a given hypernuclear core, the calculated K separation energy BK saturates with the number of K mesons for more than roughly 10 mesons, with BK bounded from above by 200 MeV. The associated baryonic densities saturate at values 2-3 times nuclear-matter density within a small region where the K-meson densities peak, similarly to what was found for multi-K nuclei. The calculations demonstrate that particle-stable multistrange {N,Λ,Ξ} configurations are stable against strong-interaction conversions Λ→ N K and Ξ→ N K K, confirming and strengthening the conclusion that kaon condensation is unlikely to occur in strong-interaction self-bound strange hadronic matter.
