| Research Abstract |
By carrying out lattice QCD numerical simulations, we found that one stable H-dibaryon exists in the flavor SU(3) symmetric QCD worlds. This is a historical success which proved for the first time that hadron other than baryon and meson can exist in the QCD world. And this finding confirmed the prediction by Dr. R. Jaffe with an effective theory, by basing on the QCD after 37 years. In the latter half of the period, we estimated the H-dibaryon in the real world by combining lattice QCD result at a symmetric point and phenomenological inputs. We found that it is likely that the H-dibaryon becomes at least a resonance state in the real world.
