Computational Particle Physics with Massively Parallel Cluster Computer

强子的强相互作用是用QCD描述的。结合PACS-CS并行集群计算机对模拟算法的革命性改进和计算能力的提高，实现了对具有物理质量的u，d，s夸克全动力学真空极化效应的物理点模拟。这解决了自80年代以来的长期目标，并使通过精确计算强子质量谱和其他物理量来验证QCD成为可能。直接基于QCD的氦核计算为核研究开辟了新的方向。

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.
