Outline of Final Research Achievements

We study the structures of exotic hadrons on the basis of Quantum Chromodynamics(QCD), which is the fundamental theory of strong interaction in physics. The method to extract the hadronic interactions using lattice QCD is extended to coupled-channel problems and applied to the possible charmed exotic hadrons, and the structures of the exotic hadrons are investigated.
In this study, we investigate the hadronic interactions using lattice QCD to search for the candidates of exotic hadrons such as Tcc, Tcs, Zc(3900) and discuss their structures. Furthermore, we study how those structures affect the experimentally obtained spectra.
