Abstract

Motivated by the recently observed hypernucleus (Kiso event) Ξ15^{15}_{\Xi}C (14^{14}N+Ξ+\Xi^-), we identify the state of this system theoretically within the framework of the relativistic-mean-field and Skyrme-Hartree-Fock models. The ΞN\Xi N interactions are constructed to reproduce the two possibly observed Ξ\Xi^- removal energies, 4.38±0.254.38\pm 0.25 MeV or 1.11±0.251.11\pm 0.25 MeV. The present result is preferable to be 14N(g.s.)+Ξ(1p)^{14}{\rm N}({\rm g.s.})+\Xi^-(1p), corresponding to the latter value.
