Description
Nucleon-Nucleon interaction plays an essential role in nuclear
physics. In the same way, hyperon-hyperon interactions should play an
important role in hyper nuclear physics. However, unlike the nucleons
which 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, by using the gauge configurations at the (almost) physical
point (m(pi)=146 MeV) on a huge spatial lattice (8fm)^4, we present
our latest result on the hyperon-hyperon potentials for S=-3 sector
(XiSigma & XiSigma-XiLambda) from the Nambu-Bethe-Salpeter wave
functions based on the HAL QCD method.
