论文摘要
对渐近状态的描述是la faddeev-kulish的描述,人们引起了人们的兴趣。在这方面,在文献中,在软扩展中以辐射为辐射的渐近状态的渐近状态的全球表示,在文献中被称为广义威尔逊线(GWL),并且最近发现了用于因素化定理的衍生化定理用于散射现象学相关性的应用。在本文中,我们根据相对论旋转粒子的众所周知的超对称文字形式主义来重新审视GWL的推导。特别是,我们讨论了文字超对称性的重要性,即了解软背景字段对渐近动力学的贡献。我们还为GLUON案例提供了GWL的派生,该案例以前在文献中不可用,从而将近代到软的玻色子校正扩展到Yang-Mills理论。最后,我们对当前研究中可能的应用发表了有关渐近状态在散射幅度和重力理论及其经典限制中的应用。
There has been a renewed interest in the description of dressed asymptotic states a la Faddeev-Kulish. In this regard, a worldline representation for asymptotic states dressed by radiation at subleading power in the soft expansion, known as the Generalized Wilson Line (GWL) in the literature, has been available for some time, and it recently found applications in the derivation of factorization theorems for scattering processes of phenomenological relevance. In this paper we revisit the derivation of the GWL in the light of the well-known supersymmetric wordline formalism for the relativistic spinning particle. In particular, we discuss the importance of wordline supersymmetry to understand the contribution of the soft background field to the asymptotic dynamics. We also provide a derivation of the GWL for the gluon case, which was not previously available in the literature, thus extending the exponentiation of next-to-soft gauge boson corrections to Yang-Mills theory. Finally, we comment about possible applications in the current research about asymptotic states in scattering amplitudes for gauge and gravity theories and their classical limit.
