Abstract
We computed a set of structures which appear in the four-point function of protected operators of dimension two in Super Yang Mills with gauge group, at any order in a large expansion. They are determined only by leading order CFT data. By focusing on a specific limit, we made connection with the dual supergravity amplitude in flat space, where such structures correspond to iterated -cuts. We made several checks and we conjecture that the same interpretation holds for supergravity amplitudes on .
