QCD振幅的基本BCJ关系的证明

Proof of the fundamental BCJ relations for QCD amplitudes

Leonardo de la Cruz, Alexander Kniss, Stefan Weinzierl

摘要:

基本的BCJ关系是具有不同循环排序的原始树振幅之间的线性关系。循环序因胶子的插入位置不同而不同。基本BCJ关系的系数在洛伦兹不变量$2 p_i p_j$中是线性的。对于纯胶子振幅和${\mathcal N}=4$ super-Yang-Mills理论中的振幅,BCJ-关系是很好的.最近,已经证实BCJ关系也适用于QCD振幅。本文给出了这个猜想的一个证明。这个证明对无质量和有质量的夸克都是有效的。

英文摘要:

The fundamental BCJ-relation is a linear relation between primitive tree amplitudes with different cyclic orderings. The cyclic orderings differ by the insertion place of one gluon. The coefficients of the fundamental BCJ-relation are linear in the Lorentz invariants $2 p_i p_j$. The BCJ-relations are well established for pure gluonic amplitudes as well as for amplitudes in ${\mathcal N}=4$ super-Yang-Mills theory. Recently, it has been conjectured that the BCJ-relations hold also for QCD amplitudes. In this paper we give a proof of this conjecture. The proof is valid for massless and massive quarks.
