All loop structures in supergravity amplitudes on AdS5 × S5 from CFT
Résumé
We compute a set of structures which appear in the four-point function of protected operators of dimension two in super Yang Mills with SU(N) gauge group, at any order in a large N expansion. They are determined only by leading order CFT data. By focusing on a specific limit, we make connection with the dual supergravity amplitude in flat space, where such structures correspond to iterated s-cuts. We make several checks and we conjecture that the same interpretation holds for supergravity amplitudes on AdS5 × S5.
