标题： Lattice QCD -- from quark confinement to asymptotic freedom

摘要： 根据目前的理解，强相互作用现象的观测多样性由量子色动力学描述，量子色动力学是一种仅有很少参数的规范场论。 在此背景下，一个基本问题是介子和核子的世界如何与高能下理论的性质相关联，在高能下，夸克和胶子是重要的自由度。 QCD 的格点形式结合数值模拟和标准微扰论是允许在定量水平上解决这一问题的工具。 显示英文摘要

摘要： According to the present understanding, the observed diversity of the strong interaction phenomena is described by Quantum Chromodynamics, a gauge field theory with only very few parameters. One of the fundamental questions in this context is how precisely the world of mesons and nucleons is related to the properties of the theory at high energies, where quarks and gluons are the important degrees of freedom. The lattice formulation of QCD combined with numerical simulations and standard perturbation theory are the tools that allow one to address this issue at a quantitative level.
