# A Fast Algorithm for Lattice Hyperonic Potentials

@article{Nemura2016AFA, title={A Fast Algorithm for Lattice Hyperonic Potentials}, author={Hidekatsu Nemura and Sinya Aoki and Takumi Doi and Shinya Gongyo and Tetsuo Hatsuda and Yoichi Ikeda and Takashi Inoue and Takumi Iritani and Noriyoshi Ishii and Takaya Miyamoto and Keiko Murano and Kenji Sasaki}, journal={arXiv: High Energy Physics - Lattice}, year={2016} }

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.

The factor tree method shows promising speed-ups for small nuclei and could extend the method to larger nuclei, but it should be noted that the memory used will become prohibitive for large nuclei.
