TL;DR: In this article, the nucleon-nucleon potential is studied by lattice QCD simulations in the quenched approximation, using the plaquette gauge action and the Wilson quark action on a ${32}^{4}$ [$\ensuremath{\simeq}(4.4

TL;DR: The flavor-singlet H dibaryon, which has strangeness -2 and baryon number 2, is studied by the approach recently developed for the baryons-baryon interactions in lattice QCD and the potential is found to be insensitive to the volume.

Abstract: We present full accounts of a method to extract nucleon-nucleon ( NN ) potentials from the Bethe-Salpter amplitude in lattice QCD. The method is applied to two nucleons on the lattice with quenched QCD simulations. By disentangling the mixing between the Sstate and the D-state, we obtain central and tensor potentials in the leading order of the velocity expansion of the non-local NN potential. The spatial structure and the quark mass dependence of the potentials are analyzed in detail. Subject Index: 164, 232, 234

TL;DR: In this paper, the Nambu-Bethe-Salpeter wave function was used to extract non-local hadron-hadron potential and phase shift in the S 0 1 channel.

TL;DR: In this article, a bound H-dibaryon in the SU ( 3 ) limit is found in the flavor-singlet J P = 0 + channel with the binding energy of about 26 MeV for the lightest quark mass M ps = 469 MeV.
