QCD振幅的关系和表示

Relations and representations of QCD amplitudes

Leonardo de la Cruz, Alexander Kniss, Stefan Weinzierl

摘要:

在这次演讲中,我们回顾原始QCD树振幅的关系和表示。涵盖的主题包括BCJ关系,CHY表示和KLT关系。我们将特别强调这些关系和表象如何从纯杨-米尔斯理论推广到QCD。KLT关系从纯杨-米尔斯到QCD的推广包括了大质量夸克的情况。在引力方面,我们得到假设的粒子与引力强度相互作用,它可以是有质量的和非相对论的。

英文摘要:

In this talk we review relations and representations of primitive QCD tree amplitudes. Topics covered include the BCJ relations, the CHY representation, and the KLT relations. We will put a special emphasis on how these relations and representations generalise from pure Yang-Mills theory to QCD. The generalisation of the KLT relations from pure Yang-Mills to QCD includes the case of massive quarks. On the gravity side we then obtain hypothetical particles interacting with gravitational strength, which can be massive and non-relativistic.
