Abstract

Motivated by the recently observed hypernucleus (Kiso event) CΞ15 (N14+Ξ-), we identify the state of this system theoretically within the framework of the relativistic-mean-field and Skyrme-Hartree-Fock models. The ΞN interactions are constructed to reproduce the two possibly observed Ξ- removal energies, 4.38±0.25 MeV or 1.11±0.25 MeV. The present result is preferable to be N14(g.s.)+Ξ-(1p), corresponding to the latter value.
