Description

The determination of baryon-baryon interactions directly from QCD is highly awaited. Especially for the strangeness S=-2 two-baryon system, we can investigate the SU(3) structure and its breaking effect of baryon-baryon interactions because the flavor singlet combination is allowed only in this system. Our approach is deriving a potential from coupled channel Schroedinger equation using Nambu-Bethe-Salpeter wave function measured on the lattice. We will report our latest results of the S=-2 baryon-baryon interactions and the fate of H-dibaryon by lattice QCD simulation employing quark masses around the physical point on a huge lattice volume of L=8fm generated by K computer at AICS.
