Research Abstract

We studied hadron systems with lattice QCD, which is one of the most reliable methods for the study of strong interactions. We determined the flavor-octet meson-baryon coupling constants for the first time. We also investigated hadron-hadron scatterings using color-SU(2) QCD and found several novel properties in hadronic interactions.
