Outline of Final Research Achievements |
Sub-atomic particles, quark and gluon, are governed by the strong interaction called Quantum Chromo Dynamics (QCD). Large scale calculation of QCD with chiral lattice fermions is performed on supercomputers to provide two important theoretical predictions: 1) CP-violating K meson decay into two pions and ε' / ε 2) hadronic contributions to anomalous magnetic moment g-2 of muon. By developing various novel theoretical and algorithmic techniques, we carried out the first computation on K→ππ and also provided, so far, the most precise prediction on g-2.
