| Outline of Final Research Achievements |
We have extended the calculation of the nuclear force in the negative parity sector with the momentum wall source to obtain the hyperon-nucleon and hyperon-hyperon potentials. By considering the idealized flavor SU(3) limit, we have obtained the lattice QCD results of hyperon potentials in the negative parity sector which include the symmetric LS and the anti-symmetric LS potentials. We found that Lambda N-Sigma N coupling plays an important role in understanding the cancellation between the symmetric and the anti-symmetric LS potentials in the Lambda N sector which is phenomenologically expected from the high precision spectroscopy of hyper nuclei. Besides, we have perforced several studies concerning the theoretical formulation of HAL QCD method by using an almost analytically treatable model, i.e., the Birse model.
