| Research Abstract |
Based on quantum chromodynamics (QCD), which is the fundamental theory of the strong interaction, we study the nonperturbative vacuum and hadrons such as nucleons and mesons in terms of quarks and gluons. In particular, we use lattice QCD, i.e., the first-principle calculation of the strong interaction, and study "color confinement" as an important subject in theoretical physics, and multi-quark systems like "exotic hadrons", which are experimentally paid attention in recent years. We also use "holographic QCD", a new analytical method based on the superstring theory.
