We thank members of PACS Collaboration for the gauge configuration generation. The lattice QCD calculations have been performed on the K computer at RIKEN, AICS (hp120281, hp130023, hp140209, hp150223, hp150262, hp160211, hp170230), HOKUSAI FX100 computer at RIKEN, Wako (G15023, G16030, G17002) and HA-PACS at University of Tsukuba (14a-20, 15a-30). T.D. and T.H. are supported in part by RIKEN iTHES Project and iTHEMS Program. We thank ILDG/JLDG [27] which serves as an essential infrastructure in this study. This work is supported in part by MEXT Grant-in-Aid for Scientific Research (JP15K17667), SPIRE (Strategic Program for Innovative REsearch) Field 5 project, "Priority Issue on Post-K computer" (Elucidation of the Fundamental Laws and Evolution of the Universe) and Joint Institute for Computational Fundamental Science (JICFuS).

N2 - We present the latest lattice QCD results for baryon interactions obtained at nearly physical quark masses. Nf = 2 + 1 nonperturbatively O(a)-improved Wilson quark action with stout smearing and Iwasaki gauge action are employed on the lattice of (96a)4 ? (8.1fm)4 with a-1 ? 2.3 GeV, where mπ ? 146 MeV and mK ? 525 MeV. In this report, we study the two-nucleon systems and two-Ξ systems in 1S0 channel and 3S1-3D1 coupled channel, and extract central and tensor interactions by the HAL QCD method. We also present the results for the N? interaction in 5S2 channel which is relevant to the N? pair-momentum correlation in heavy-ion collision experiments.
