杨-米尔斯理论中单圈水平上的一般BCJ关系

On General BCJ Relation at One-loop Level in Yang-Mills Theory

Yi-Jian Du, Hui Luo

摘要:

BCJ关系揭示了颜色结构和运动学结构之间的对偶,可以用来减少树级独立颜色排序振幅的数量。本文参照杨-米尔斯理论中的环能级,研究了类BCJ关系。N = 4 SYM中的四点单圈例子可以提示被积函数的关系。五点算例表明,一般公式可用酉割法证明。然后,我们将通过D维酉割证明1-loop被积函数的“一般”BCJ关系,这可以被视为Boels和Isermann在[arXiv:1109.5888 [hep-th]]和[arXiv:1110.4462 [hep-th]]中给出的(基本)BCJ关系的非平凡推广。

英文摘要:

BCJ relation reveals a dual between color structures and kinematic structure and can be used to reduce the number of independent color-ordered amplitudes at tree level. Refer to the loop-level in Yang-Mills theory, we investigate the similar BCJ relation in this paper. Four-point 1-loop example in N = 4 SYM can hint about the relation of integrands. Five-point example implies that the general formula can be proven by unitary- cut method. We will then prove a 'general' BCJ relation for 1-loop integrands by D-dimension unitary cut, which can be regarded as a non-trivial generalization of the (fundamental)BCJ relation given by Boels and Isermann in [arXiv:1109.5888 [hep-th]] and [arXiv:1110.4462 [hep-th]].
