Theoretical Study of Exotic Multi-Quark and Multi-Hadron Systems

强子能谱、强子物质、超核能谱这三个主要学科在日本各地的理论研究小组中得到了广泛的探索。我们的努力集中在与在Spring-8和J-Parc等地进行实验的实验物理学家的合作上，以及在这些领域教育和鼓励年轻的学生和博士后研究人员。我们在五夸克、可能的K核态、致密的QCD及其相结构、超核和广义核力的伽马能谱、重子-重子相互作用的晶格QCD计算、双超核的结构等方面取得了重大进展。

Three major subjects, A.Hadron Spectroscopy, B.Hadronic Matter, C.Hypernuclear Spectroscopy, have been extensively explored by organizing theoretical research groups all over in Japan. We focused our efforts on collaborations with experimental physicists carrying out experiments at SPring-8 and J-PARC etc., and also on to educate and encourage young students and post-doc researchers in these fields. We have achieved major development in the areas of exotic hadron spectroscopy including pentaquarks, possible K nucleus states, dense QCD and its phase structure, gamma spectroscopy of hypernuclei and generalized nuclear force, lattice QCD computation of baryon-baryon interactions, structure of double hypernuclei.
