We studied hyperonic interactions by lattice QCD simulations through a coupled channel formalism. Our approach to baryon-baryon interactions derives a potential from inverting the Schrodinger equation using a Nambu-Bethe-Salpeter (NBS) wave function simulated on the lattice. The quark mass dependences and flavor SU(3) breaking effects of the potential matrix are also discussed by comparing with results of gauge configurations obtained with different quark masses. Our numerical results are obtained from three ensembles of 2+ 1-flavor QCD gauge configurations, which correspond to m pi similar to 700, 570 and 410 MeV, provided by the PACS-CS Collaboration.
