Outline of Final Research Achievements |
The determination of three-nucleon forces, non-trivial interactions among three nucleons, is one of the most important subject in modern nuclear physics. In this study, we calculate three-nucleon forces directly based on QCD, the Standard Model of particle physics, by means of first-principles lattice QCD simulations. Some of the major achievements are (1) development of a novel computational algorithm (Unified Contraction Algorithm) which speeds up the computation by a factor of 192 (2) establishing the theoretical definition of three-nucleon forces in field theory based on the asymptotic behavior of Nambu-Bethe-Salpeter wave functions for multi-particles (3) observation of the repulsive three-nucleon forces at short distance by lattice QCD simulations at various quark masses and lattice spacings.
