摘要：
The recent update of the strangeness -2 ESC08c Nijmegen potential incorporating the NAGARA and KISO events predicts a Xi N bound state, D*, in the S-3(1)(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 Xi N state is merged with N's, Lambda's, Sigma's, or Xi's, making use of the most recent updates of the two-body ESC08c Nijmegen potentials. We found that there appear stable states in the Xi NN and Xi Xi N systems, the Xi Lambda N and Xi Sigma N systems being unbound.
