QCD的背景场法因式分解证明

Proof of Factorization Using Background Field Method of QCD

Gouranga C Nayak

摘要:

因式分解定理在高能对撞机研究标准模型和超标准模型物理中起着核心作用。Collins、Soper和Sterman用图解法给出了微扰论中所有阶的因式分解定理的证明。人们可能会问,是否可以通过拉格朗日水平上的对称性考虑来获得因式分解定理的证明。在本文中,我们提供了这样的证明。

英文摘要:

Factorization theorem plays the central role at high energy colliders to study standard model and beyond standard model physics. The proof of factorization theorem is given by Collins, Soper and Sterman to all orders in perturbation theory by using diagrammatic approach. One might wonder if one can obtain the proof of factorization theorem through symmetry considerations at the lagrangian level. In this paper we provide such a proof.
