Research Abstract

In order to reveal the vacuum structure and quark dynamics from QCD, we established the lattice QCD calculation based on large scale numerical simulation in two apProaches:one is the realistic QCD simulation at the physical point using wilson fermion, the other is the QCD simulation with exact chiral symmetry using Overlap fermion. we achieved the study of hadron dynamics including the spectrum and hadron interactions, and determined the low energy constants of the chiral dynamics.
