Outline of Final Research Achievements

I researched the properties of the medium effect when the heavy hadrons and quarks with charm or bottom flavor exists as impurity particles in the nuclear and quark matter. Firstly, I discussed the impurity energies, the spin-isospin Kondo effect, and the QCD (color) Kondo effect from the view of the microscopic interaction. Especially I focused on the systematic study in the field-theoretical framework, paying an attention to the nonperturbative effect caused by the impurities. Secondly, I discussed the possible variety of phases of high-density matter in order to make the role of the medium effect clear. I applied the Ginzburg-Landau theory to research the properties of neutron P-wave superfluids, and discussed new properties of high-density nuclear matter.

Academic Significance and Societal Importance of the Research Achievements

チャームやボトムのような重いハドロンについて真空における様々な新奇なハドロン状態(エキゾチックハドロン)の実験観測が報告されている。一般的にこれらはマルチクォーク状態であると考えられており、素粒子標準理論の一つである量子色力学におけるカラー閉じ込め問題と密接に関係しているテーマを与える。一方で重いハドロン・クォークは真空のみならず有限密度媒質にも存在することが可能である。このような状態は高エネルギー加速器施設において研究される可能性があるため、今回の理論的な研究によって媒質の新しい性質を明らかにするとともに重いハドロン・クォークによる様々な不純物効果を予言した。
