Light hypernuclei and hyperon-nucleon potentials based on lattice QCD

We will provide an overview of recent theoretical studies on light hypernuclei and lattice QCD hyperon-nucleon potentials. Results of ab initio calculations of s-shell hypernuclei are outlined, revealing the importance of coupled-channel such as $\Lambda N-\Sigma N$. The challenge to obtain the lattice QCD potentials will also be presented.
