Abstract
The flavor-singlet dibaryon, which has strangeness and baryon number 2, is studied by the approach recently developed for the baryon-baryon interactions in lattice QCD. The flavor-singlet central potential is derived from the spatial and imaginary-time dependence of the Nambu-Bethe-Salpeter wave function measured in full QCD simulations with the lattice size of . The potential is found to be insensitive to the volume, and it leads to a bound dibaryon with the binding energy of 30–40 MeV for the pseudoscalar meson mass of 673–1015 MeV.
