多夸克单圈QCD振幅的色分解

Color decomposition of multi-quark one-loop QCD amplitudes

Christian Reuschle, Stefan Weinzierl

摘要:

在这个演讲中,我们讨论了树级和单圈QCD振幅与任意数量的夸克和胶子的颜色分解。我们提出了一种方法的部分振幅分解成原始振幅,这是基于洗牌关系,是纯粹的组合。封闭的公式推导,这不需要一个系统的线性方程组的反演。

英文摘要:

In this talk we discuss the color decomposition of tree-level and one-loop QCD amplitudes with arbitrary numbers of quarks and gluons. We present a method for the decomposition of partial amplitudes into primitive amplitudes, which is based on shuffle relations and is purely combinatorial. Closed formulae are derived, which do not require the inversion of a system of linear equations.
