Graviton scattering in AdS(5) x S-5 at two loops

We report a result for the third-order correction in 1/N expansion to the four-point correlator of the stress tensor multiplet in N = 4 super Yang-Mills theory at large 't Hooft coupling, which corresponds to the two-loop scattering of four gravitons in the dual AdS(5) x S-5 supergravity. This is obtained by bootstrapping an educated ansatz based on intuitions from the hidden 10-dimensional conformal symmetry.
