软胶子恢复的路径积分方法

Path Integral Methods for Soft Gluon Resummation

C. D. White

摘要:

我们描述了一个新的框架软胶子重建的基础上,路径积分方法。这种方法恢复了以前在程函近似下得到的结果,其中所有发射的胶子都变软了。此外,一个明确的物理解释允许直接扩展的框架超越程函近似,我们用它来分类的结构下程函校正矩阵元素。

英文摘要:

We describe a new framework for soft gluon resummation, based on path integral methods. The approach recovers previous results obtained in the eikonal approximation, in which all emitted gluons become soft. Furthermore, a clear physical interpretation allows straightforward extension of the framework to beyond the eikonal approximation, and we use this to classify the structure of next-to-eikonal corrections to matrix elements.
