A Fast Algorithm for Lattice Hyperonic Potentials

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.
