| Outline of Final Research Achievements |
To understand Baryon-Baryon interaction in unified way, we have studied S=-2 hyperon-hyperon interaction. In detail, we focused on NNΞ and NNNΞ three- and four-body systems which has never been observed. As for ΞN interaction, we employed ΞN potential with basis on Lattice QCD,which is one of ab-initio calculation. As a result, there was no bound state for NNΞ three-body system. On the other hand,we had a bound state for NNNΞ four-body system. We propose to perform heavy ion reaction to observe it. We published pupress release in March in 2020.
