Our mission is to explore Quantum Chromodynamics (QCD), which is the fundamental theory describing the dynamics of quarks and gluons.

One of the challenges in hadron physics is to explore the structure of hadrons described as a quark-gluon many body system. Above all, exotic hadrons which are formed from four or five quarks including heavy quarks have been found successively in recent experiments. Therefore, theoretical elucidation of the exotic structure is awaited.

Another challenge is to comprehensively understand hadrons and quark-gluon many body system in finite temperature and finite density. In particular, the research of high density matter leads to clarification of the internal structure of neutron star, the merger of neutron stars, the supernova explosion, etc.

Our group also investigates the mass generation mechanism of nucleons (protos and neutrons). Since a matter in the universe consists mainly of nucleons making up atomic nuclei, revealing this mechanism leads to understanding the origin of "mass" in this world. The mass generation is closely related to the "spontaneous chiral symmetry breaking" which has been studied in the QCD at finite temperature and density, hadron structures, etc.

Many unanswered questions in the hadron physics have been provided by experimental and theoretical studies so far. In order to solve them from various aspects, we have developed new theories in the framework of effective and phenomenological models, and also proposed for future experiments. Moreover, we have strived to connect hadron physics with the related fields recently.
