AI总结:

本研究在强耦合极限下解析了平面 $\mathcal{N}=4$ 超杨-米尔斯理论中四条次领头 Regge 轨迹的共形场论数据,发现其中一条在平直空间极限下从 OPE 中解耦,暗示了新的选择定则。

摘要:

我们研究了平面 4D $\mathcal{N} = 4$ 超杨-米尔斯理论在强't Hooft耦合极限下的共形场论数据(CFT-data)。该区域探索了对偶 AdS 平直空间极限中质量大的短弦物理。我们聚焦于与 Virasoro-Shapiro 振幅对偶的四点函数算符乘积展开(OPE)中交换的质量大的短弦的 CFT-data。在平直空间极限下,这些 CFT-data 排列成 Regge 轨迹。利用近期 AdS Virasoro-Shapiro 振幅计算、可积性以及基于 CFT-data 在自旋上解析性的规定所取得的进展,我们能够确定四条独特的次领头 Regge 轨迹上所有 CFT-data 在领头非平凡阶作为弦质量级的函数。我们的预测之一是,在平直空间极限下,四条独特的次领头 Regge 轨迹中的一条从 OPE 中解耦。这暗示了平直空间极限中存在一个涌现的选择定则,类似于我们之前在 arXiv:2310.06041 中的结果。我们的方法应适用于多种类似设置,如 AdS Veneziano 振幅或 ABJM 理论。

英文摘要:

We study the conformal field theory data (CFT-data) of planar 4D $\mathcal{N} = 4$ Super-Yang-Mills theory in the strong 't Hooft coupling limit. This regime explores the physics of massive short strings in the flat-space limit of the dual AdS. We focus on the CFT-data of the massive short strings exchanged in the operator product expansion (OPE) of the four-point function dual to the Virasoro-Shapiro amplitude. This CFT-data arranges itself into Regge trajectories in the flat-space limit. Using inputs from recent advances in the computation of the AdS Virasoro-Shapiro amplitude, integrability, and a stipulation based on analyticity of the CFT-data in spin, we are able to fix all the CFT-data on the four unique sub-leading Regge trajectories, at leading non-trivial order, as a function of the string-mass level. One of our predictions is that one of the four unique sub-leading Regge trajectories decouples from the OPE in the flat-space limit. This hints at an emergent selection rule in the flat-space limit, similar to our previous results in arXiv:2310.06041. Our procedure should be applicable in a variety of similar setups like for the AdS Veneziano amplitude or in ABJM.
