Abstract

We investigate the strangeness S = -2 two-baryon system by lattice QCD theory at nearly physical point with a huge lattice volume of La = 8.2fm generated on the K computer at AICS. Our approach (HAL QCD method) enable us to derive a potential from coupled channel Schrödinger equation using the Nambu-Bethe-Salpeter (NBS) wave functions. We report our latest results of the S = -2 baryon-baryon interactions focusing on the 1S0 with I = 0 channel where the Hdibaryon state is predicted by several model calculations.
