论文摘要
我们提出了一个系统的过程，用于在n = 4的n = 4 super yang-mills中获得所有单个痕迹1/2-bps相关器，该过程与ADS5XS5中IIB字符串理论的四点树级幅度相对应。潜在的想法是计算来自ADS5XS5上10D有效的现场理论的广义接触图，其系数是由平面空间Virasoro-Shapiro振幅固定的，直到与10D协同衍生物相关的歧义，需要其他信息，例如需要其他信息，例如本地化。我们通过计算所有单个跟踪1/2-bps相关器的超级预测来说明此过程，最高$ O（α'^7）$，并拼出将其扩展到$α'$的任何顺序的一般算法。
We propose a systematic procedure for obtaining all single trace 1/2-BPS correlators in N=4 super Yang-Mills corresponding to the four-point tree-level amplitude for type IIB string theory in AdS5xS5. The underlying idea is to compute generalised contact Witten diagrams coming from a 10d effective field theory on AdS5xS5 whose coefficients are fixed by the flat space Virasoro-Shapiro amplitude up to ambiguities related to commutators of the 10d covariant derivatives which require additional information such as localisation. We illustrate this procedure by computing stringy corrections to the supergravity prediction for all single trace 1/2-BPS correlators up to $O(α'^7)$, and spell out a general algorithm for extending this to any order in $α'$.
