Abstract

The recent update of the strangeness -2 ESC08c Nijmegen potential incorporating the NAGARA and KISO events predicts a ΞN bound state, D∗, in the S13(I=1) channel. We study if the existence of this two-body bound state could give rise to stable three-body systems. For this purpose we solve the bound state problem of three-body systems where the ΞN state is merged with N's, Λ's, Σ's, or Ξ's, making use of the most recent updates of the two-body ESC08c Nijmegen potentials. We found that there appear stable states in the ΞNN and ΞΞN systems, the ΞΛN and ΞΣN systems being unbound.
