A Novel Framework for Higher Loop Witten Diagrams
Aidan Hederschee, University of Michigan,

The differential representation is a novel formalism for studying anti-de Sitter boundary correlators which provides a transparent understanding of the correlators' analytic structure. The differential representation is analogous to the momentum space representation in flat space under the replacement of momentum vectors by conformal generators acting on AdS contact diagrams. In this talk, I propose a generalization of the differential representation beyond tree level using operator-valued integration. I compute three-point bubble and triangle Witten diagrams directly using operator-valued integration. For the bubble diagram, I cross-check the operator-valued integration result by computing the same diagram using more established techniques.
