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), HOKUSAI FX100 computer at RIKEN, Wako (G15023, G16030) and HA-PACS at University of Tsukuba (14a-20, 15a-30). We thank ILDG/JLDG [15] 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 and "Priority Issue on Post-K computer" (Elucidation of the Fundamental Laws and Evolution of the Universe).

N2 - The strangeness S = -2 baryon-baryon interaction is investigated directly from the fundamental theory of the strong interaction, QCD. The HAL QCD method enables us to extract baryon interactions from the Nambu-Bethe-Salpeter wave functions without using any experimental information. We present our latest result on the S = -2 baryon interactions and discuss the Hdibaryon state using potentials which are calculated by using the (almost) physical point gauge configurations with large lattice volume of (8.1fm)4 generated on the K-computer.
