Abstract

We present lattice QCD results of baryon-baryon potentials in S = -3 sector, i.e., Ξ∑ (I = 3=2) potentials and ΞΛ-Ξ∑ coupled channel potentials (I = 1=2) by using the 2+1 flavor gauge config- urations with almost the physical quark masses generated on 964 lattice with a-1 ≃ 2:3 GeV and L = 96a ≃ 8:1 fm where mπ ≃ 146 MeV and mK ≃ 525 MeV. These potentials are obtained based on the time-dependent HAL QCD method with a non-relativistic approximation. Qualitative be- haviors of the results are found to be consistent with those in the flavor SU(3) limit.
