Color-factor symmetry using perturbiner methods for tree-level amplitudes of Yang-Mills theory coupled to matter
AI总结:
研究包含胶子和物质场的杨-米尔斯理论树图振幅的色因子对称性,利用递归微扰方法,给出了含任意数量特定物质场及至少一个胶子的树图振幅色因子对称性的通用简化证明。
AI中文摘要:
伯恩-卡拉斯科-约翰松关系是包含胶子以及可能还有物质场的树图过程部分振幅之间与螺旋度无关的约束。它们是色运动学对偶性的结果,但也可通过树图振幅的色因子对称性导出。我们使用递归微扰方法对包含任意数量基本自旋为零或自旋为二分之一物质场以及至少一个胶子的所有树图振幅的色因子对称性给出了一个通用的、简化的证明。
英文摘要:
Bern-Carrasco-Johansson relations are helicity-independent constraints among the partial amplitudes of tree-level processes containing gluons and possibly also matter fields. They are a consequence of color-kinematic duality, but alternatively can be derived using the color-factor symmetry of tree-level amplitudes. We use recursive perturbiner methods to present a general, streamlined proof of the color-factor symmetry of all tree-level amplitudes containing an arbitrary number of fundamental spin-zero or spin-one-half matter fields and at least one gluon.
