论文摘要
我们通过利用其分析结构来回顾用于平面$ \ Mathcal {n} = 4 $ Super Yang-Mills理论的六个和七粒子振幅的引导方法。我们专注于最近发现的两个属性，这些属性分别在符号和功能级别中大大简化了这种构建：扩展的Steinmann关系或等效的聚类邻接和共同原理。然后，我们演示了它们在NMHV和MHV扇区中分别通过六个和七个循环确定六粒子振幅的力量，以及NMHV七粒子振幅到四个循环的符号。
We review the bootstrap method for constructing six- and seven-particle amplitudes in planar $\mathcal{N}=4$ super Yang-Mills theory, by exploiting their analytic structure. We focus on two recently discovered properties which greatly simplify this construction at symbol and function level, respectively: the extended Steinmann relations, or equivalently cluster adjacency, and the coaction principle. We then demonstrate their power in determining the six-particle amplitude through six and seven loops in the NMHV and MHV sectors respectively, as well as the symbol of the NMHV seven-particle amplitude to four loops.
