Some Basic Concepts of Perturbative QCD

Abstract

This is a brief review of some of the basic concepts of perturbative QCD, including infrared safety and factorization, relating them to more familiar ideas from quantum mechanics and relativity. It is intended to offer perspective on methods and terms whose use is commonplace, but whose physical origins are sometimes obscure.
