An international research group including Dr. Tetsuo Hatsuda (Program Director, iTHEMS), and Takumi Doi (Senior Research Scientist, iTHEMS / Quantum Hadron Physics Laboratory, RIKEN) has theoretically predicted the existence of a new hyper-nucleus (hypernucleus), the Xi-Tetrabaryon, consisting of one Xi-particle and three nucleons.
