测地线图、引力相互作用和OPE结构

Geodesic Diagrams, Gravitational Interactions & OPE Structures

Alejandra Castro, Eva Llabrés, Fernando Rejon-Barrera

摘要:

我们给出了一个系统的程序来评估共形分波涉及对称张量的任意CFT $_d$使用测地威滕图在AdS $_{d+1}$。使用这个过程中,我们讨论了如何画一条线之间的张量结构的CFT和立方相互作用的AdS。我们对比这张地图已知的结果,使用三点威滕图:通过体积与测地积分得到的地图不同。尽管有这些差异,我们展示了如何分解四点交换威滕图的测地线图,我们讨论了产品的扩展本地散装领域在AdS。

英文摘要:

We give a systematic procedure to evaluate conformal partial waves involving symmetric tensors for an arbitrary CFT$_d$ using geodesic Witten diagrams in AdS$_{d+1}$. Using this procedure we discuss how to draw a line between the tensor structures in the CFT and cubic interactions in AdS. We contrast this map to known results using three-point Witten diagrams: the maps obtained via volume versus geodesic integrals differ. Despite these differences, we show how to decompose four-point exchange Witten diagrams in terms of geodesic diagrams, and we discuss the product expansion of local bulk fields in AdS.
