Research Abstract

The strong interaction of hadrons are described by QCD. Combining the revolutionary improvement of the simulation algorithm and an increase of computing power provided by PACS-CS parallel cluster computer, physical point simulation including the full dynamical vacuum polarization effects of u, d, s quarks with physical masses was achieved. This has solved the long-standing goal since 1980's, and has enabled the verification of QCD with a precision calculation of the hadron mass spectrum and other physical quantities. New direction of nuclear research was explored by a calculation of helium nucleus directly based on QCD.
