Hypernuclear physics ハイパー核物理学

By studying the structure of the hypernuclei (atomic nuclei containing strange particles called hyperons in addition to the usual nucleons) from the viewpoints of three- and four-body models, we aim at an accurate and unified understanding of the interactions between hyperons and nucleons. 現在の研究室ではハイパー核物理分野での研究を活発に行っています。この中性子、陽子、とハイペロンと呼ばれる粒子で構成されたハイパー核を量子力学的３体・４体問題の観点から構造研究を行うことにより、ハイペロンと核子間の相互作用の統一的理解を目指しています。最近は、５体問題まで適用が可能になりました。
