AdS Box Graphs, Unitarity and Operator Product Expansions
L. Hoffmann, L. Mesref, W. Ruehl
We develop a method of singularity analysis for conformal graphs which, in particular, is applicable to the holographic image of AdS supergravity theory. It can be used to determin…

A note on the analyticity of AdS scalar exchange graphs in the crossed channel
L. Hoffmann, A. C. Petkou, W. Ruehl
We discuss the analytic properties of AdS scalar exchange graphs in the crossed channel. We show that the possible non-analytic terms drop out by virtue of non-trivial properties o…
