摘要：It has been believed that lattice QCD is an ideal tool to investigate the nonperturbative dynamics of strong interactions from first principles. In order to fullfill the promise a lot of effort has been devoted to control the systematic errors to increase reliability. We explain what kind of systematic errors still remain in current lattice QCD simulations. Another important issue is the recent progress in phase shift analysis of hadron-hadron interactions and direct investigation of multi-nucleon systems based on QCD. We discuss the ρ-ππ resonance and the nuclei with small mass number.
