QED和QCD的非相对论束缚态理论已经相当成熟,并适合于教科书水平的理解和计算。在这次演讲中,我们给出了一个介绍性的审查有关的最近使用微扰QCD计算的重夸克偶素谱的以下主题:(1)高阶计算的技术发展,(2)物理预测,(3)三圈静态QCD势的解析评估的挑战。
Non-relativistic bound state theories for QED and QCD have become fairly mature and amenable to a textbook-level understanding and computation. In this talk we give an introductory review of the following subjects related to the recent computation of the heavy quarkonium spectrum using perturbative QCD: (1) Technological developments in higher-order computation, (2) Physics predictions, (3) Challenge towards analytic evaluation of the 3-loop static QCD potential.
