Abstract
Recent studies of nuclear forces based on lattice QCD are presented. Not only the central potential but also the tensor potential is deduced from the Nambu–Bethe–Salpeter wave function measured with lattice QCD. This method is applied to various kinds of nuclear potentials, such as \({V_{NN}, V_{\Lambda N}, V_{p{\Xi}^0},V_{\Lambda\Lambda-N\Xi-\Sigma\Sigma}}\) (coupled-channel potential), and \({V^{\{{\bf {27},{8}_s,{1},{10},\overline{10},{8}_a}\}}}\) (flavor representation potential). The energy dependence and the angular momentum dependence of the quenched V NN is studied. A challenge for three-nucleon force from lattice QCD is also presented.
