Abstract

We describe an efficient algorithm to compute a large number of baryon-baryon interactions from $NN$ to $\Xi\Xi$ by means of HAL QCD method, which lays the groundwork for the nearly physical point lattice QCD calculation with volume $(96a)^4\approx$ ( $8.2$ fm) $^4$ . Preliminary results of $\Lambda N$ potential calculated with quark masses corresponding to ( $m_{\pi}$ , $m_{K}$ ) $\approx$ (146,525)MeV are presented.
