论文摘要
我们计算了一组结构，这些结构出现在$ \ MATHCAL {n} = 4 $ SUPER YANG MILLS中的二维操作员的四点函数中，带有$ su（n）$ gauge组，以大$ n $扩展中的任何顺序。它们仅通过领先的CFT数据来确定。通过关注特定的限制，我们与平面空间中的双重超级振幅建立了联系，在该限制中，此类结构对应于迭代的$ s $ cuts。我们进行了几次检查，并猜测相同的解释也适用于$ ads_5 \ times s^5 $上的超级振幅。
We computed a set of structures which appear in the four-point function of protected operators of dimension two in $\mathcal{N}=4$ Super Yang Mills with $SU(N)$ gauge group, at any order in a large $N$ expansion. They are determined only by leading order CFT data. By focusing on a specific limit, we made connection with the dual supergravity amplitude in flat space, where such structures correspond to iterated $s$-cuts. We made several checks and we conjecture that the same interpretation holds for supergravity amplitudes on $AdS_5 \times S^5$.
