Title: Evaluating Witten Diagram †

Speaker: Jason Kristiano †

Witten diagram describes correlation of scalar fields at the boundary of Anti-de Sitter (AdS) space. In this talk, I will explain how to evaluate the simplest Witten diagram that is generated by three-point interaction. I will also introduce correspondence with conformal field theory (CFT) and definition of Mellin amplitude.
