Coexistence of Bound Antikaons and Hyperons in Finite Nuclei

摘要

Possible existence of antikaonic nuclear bound states with hyperon (Λ, Σ~-，Ξ~-)-mixing in finite nuclei is studied within the relativistic mean-field framework, where K-baryon and K-K interactions are taken into account through coupling with the nonlinear effective chiral Lagrangian. It is shown that for the moderately attractive K~- optical potential, the ground state is composed as multi-hypernuclei without bound K~- mesons.
