| Research Abstract |
Main results of this research project are as follows. (1) We have theoretically formulated a method to calculate potentials from wave functions. (2) We have proposed a method to extract the tensor force and have calculate the tensor potential in lattice QCD. (3) We have calculated nuclear potentials in full QCD simulations. (4) We have analytically investigated the origin of the repulsive core. (5) We have calculated hyperon-nucleon potentials in lattice QCD. (6) We have investigated dependences of baryon-baryon potentials on flavor representations in the flavor SU(3) symmetric limit of lattice QCD. (7) We have shown an existence of an H-dibaryon in the flavor SU(3) symmetric limit of lattice QCD.
