Baryon interactions from lattice QCD with physical masses -- S=-3 sector: XiSigma & XiLambda-XiSigma --

Hyperon-nucleon and hyperon-hyperon interactions are important in studying the properties of hypernuclei in hypernuclear physics. However, unlike the nucleons which are quite stable, hyperons are unstable so that the direct scattering experiments are difficult, which leads to the large uncertainty in the phenomenological determination of hyperon potentials. In this talk, we use the gauge configurations generated at the (almost) physical point (m_pi=146 MeV) on a huge spatial lattice (8.1fm)^4 to present our latest result on the hyperon-hyperon potentials in S=-3 sector (XiSigma single channel & XiSigma-XiLambda coupled channel) from the Nambu-Bethe-Salpeter wave functions based on the HAL QCD method.
