在超引力条件下，我们研究了最大超对称杨-米尔斯相关器的结构。我们开发了一个算法来构造四个任意Kaluza-Klein超重力态的单圈超引力振幅，适当地对偶为单粒子算符。我们通过构造多通道相关函数的新的显式结果来说明该算法，并且我们证明了在树级退化的相关器在单环上是可区分的。该算法包含了许多直到现在还没有出现过的微妙特征。特别是，我们解决了OPE中非平凡的低扭度保护算子的存在，这些算子对于获得正确的单环结果至关重要。最后，我们概述了如何使用在树级隐藏的10d共形对称性的上下文中起作用的微分算子$\widehat{\mathcal{D}}_{PQRS}$和$\Delta^{(8)}$来重组我们的单圈相关器。
We explore the structure of maximally supersymmetric Yang-Mills correlators in the supergravity regime. We develop an algorithm to construct one-loop supergravity amplitudes of four arbitrary Kaluza-Klein supergravity states, properly dualised into single-particle operators. We illustrate this algorithm by constructing new explicit results for multi-channel correlation functions, and we show that correlators which are degenerate at tree level become distinguishable at one-loop. The algorithm contains a number of subtle features which have not appeared until now. In particular, we address the presence of non-trivial low twist protected operators in the OPE that are crucial for obtaining the correct one-loop results. Finally, we outline how the differential operators $\widehat{\mathcal{D}}_{pqrs}$ and $\Delta^{(8)}$, which play a role in the context of the hidden 10d conformal symmetry at tree level, can be used to reorganise our one-loop correlators.
