摘要：We outline the basic properties of a pertubative QCD factorization formalism that maintains exact over-all kinematics in both the initial and nal states. Such a treatment requires the use of nonperturbative factors that depend on all components of parton four-momentum. These objects are referred to as parton correlation functions. We describe the complications faced in dening parton correlation functions and discuss recent progress. Emphasis is placed on the need for precise operator denitions in a complete derivation of factorization.
