Simplicity of AdS supergravity at one loop
We demonstrate the simplicity of AdS5 × S5 IIB supergravity at one loop level, by studying non-planar holographic four-point correlators in Mellin space. We develop a systematic algorithm for constructing one-loop Mellin amplitudes from the tree-level data, and obtain a simple closed form answer for the ⟨OS2GO2SG2OpSGOpSG⟩ correlators. The structure of this expression is remarkably simple, containing only simultaneous poles in the Mellin variables. We also study the flat space limit of the Me...Expand abstract
