我们研究了平面N=4超杨-米尔斯理论中,当三个交叉比都很小时,平面N=4超杨-米尔斯理论中最大螺旋度破坏的六胶子散射振幅。它在交叉比中表现出双对数标度,由少数仅是耦合常数的函数的“反常维度”控制。受已知的弱耦合七圈结果和基于可积性的五角形算符乘积展开的启发,我们对这些反常维的全阶恢复提出了猜想。在强耦合情况下,我们的预测与弦理论的分析完全一致。有趣的是,这些反常维度中最简单的维度与描述八角形的类光极限的维度重合,即大电荷Bogomol‘nyi-Prasad-Sommerfield(BPS)算符的四点函数。
We study the maximally-helicity-violating six-gluon scattering amplitude in planar N=4 super-Yang-Mills theory at finite coupling when all three cross ratios are small. It exhibits a double logarithmic scaling in the cross ratios, controlled by a handful of "anomalous dimensions" that are functions of the coupling constant alone. Inspired by known seven-loop results at weak coupling and the integrability-based pentagon operator product expansion, we present conjectures for the all-order resummation of these anomalous dimensions. At strong coupling, our predictions agree perfectly with the string theory analysis. Intriguingly, the simplest of these anomalous dimensions coincides with one describing the lightlike limit of the octagon, namely, the four-point function of large-charge Bogomol'nyi-Prasad-Sommerfield (BPS) operators.
