Outline of Final Research Achievements

The purpose of this work is explication of new hadron states by lattice QCD. Materials consist of hadrons, and hadrons are made up with quarks. Using a fundamental theory of quarks, Quantum Chromo Dynamics(QCD), quantitative analysis of hadrons is performed.
For this purpose, a simulation code is developed. It is merged to a lattice QCD common code. Then, on very realistic gauge configurations generated by K-computer, spectrum, renormalization factors, and form factor are calculated. Furthermore, a half off-shell amplitude is obtained for the world-first time.
