Quantum chromodynamics (QCD), the theory of the strong interactions, involves quarks interacting with non-Abelian gluon fields. This theory has many features that are difficult to impossible to see in conventional diagrammatic perturbation theory. This includes quark confinement, mass generation and chiral symmetry breaking. This paper is a colloquium level overview of the framework for understanding how these effects come about.

超越图表的 QCD

量子色动力学（QCD）是强相互作用的理论，涉及夸克与非阿贝尔胶子场的相互作用。该理论具有许多在传统图解微扰理论中难以或不可能看到的特征。这包括夸克限制、质量产生和手征对称破缺。本文是关于理解这些影响如何产生的框架的学术讨论会级别概述。
