The Regge Limit of the AdS Virasoro-Shapiro Amplitude

In this talk, we consider the Regge limit of the Virasoro-Shapiro amplitude. This amplitude is understood through the AdS/CFT correspondence as a 4-point correlator in N=4 SYM. At strong 't Hooft coupling, which corresponds to a small curvature limit in the bulk, we can expand it perturbatively. We show that, following a few integral transforms, the correlator in the Regge limit can be computed from the action of appropriate differential operators on the flat space result. We finally discuss the relation of this result to the worldsheet representation of the AdS Virasoro-Shapiro amplitude.
