Baryon interactions from lattice QCD with physical masses ---S=-3 sector: XiSigma and XiLambda-XiSigma---
Abstract
We present lattice QCD results of baryon-baryon potentials in S=-3 sector, i.e., (I=3/2) potentials and - coupled channel potentials (I=1/2) by using the 2+1 flavor gauge configurations with almost the physical quark masses generated on 964 lattice with 1/a 2.3 GeV and L = 96a 8.1 fm where mpi 146 MeV and mK 525 MeV. These potentials are obtained based on the time-dependent HAL QCD method with a non-relativistic approximation. Qualitative behaviors of the results are found to be consistent with those in the flavor SU(3) limit.
