Abstract

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.
