The lattice QCD calculations have been performed on the K computer at RIKEN, AICS ( hp120281, hp130023, hp140209, hp150223, hp150262, hp160211), HOKUSAI FX100 computer at RIKEN, Wako ( G15023, G16030) and HA-PACS at University of Tsukuba ( 14a-25, 15a-33, 14a-20, 15a-30). We thank ILDG/JLDG [16] which serves as an essential infrastructure in this study.

N2 - We present our recent study on baryon-baryon (BB) interactions from lattice QCD with almost physical quark masses corresponding to (mπ ,mK) ≈ (146,525) MeV and large volume (La)4 = (96a)4 ≈ (8.1 fm)4. In order to perform a comprehensive study of BB interactions based on lattice QCD calculation with almost physical masses and to make better use of such large scale computer resources, a large number of BB interactions from NN to ΞΞ are calculated simultaneously. In this report, we focus on the strangeness S = -1 channels of the hyperon interactions by means of HAL QCD method. The coupled-channel HAL QCD method is briefly outlined. The snapshots of central and tensor potentials in 1S0 and 3S1-3D1 channels are presented for ΛN, ∑N (both the isospin I = 1/2,3/2) and their coupled-channel systems.
