Description
Nucleaon-Nucleon interaction plays an essential role in nuclear
physics. In the same way, hyperon-hyperon interactions shold play an
important role in hyper nuclear physics. However, unlike the nucleons
who are quite stable, hyperons decay quickly so that the direct
scattering experiments are difficult. As a result, phenomenological
determination of hyperon potentials involves large uncertainly. In
this talk, we present our preliminary lattice QCD results on the
determination of hyperon potentials in XiXi, XiSigma, and
XiLambda-XiSigma channels based on the HAL QCD method by using a 2+1
flavor gauge configuration near the physical point generated by K
computer.
