AdS Virasoro-Shapiro from single-valued periods

Abstract

Abstract We determine the full 1/$$ \sqrt{\uplambda} $$ λ correction to the flat-space Wilson coefficients which enter the AdS Virasoro-Shapiro amplitude in $$ \mathcal{N} $$ N = 4 SYM theory at strong coupling. The assumption that the Wilson coefficients are in the ring of single-valued multiple zeta values, as expected for closed string amplitudes, is surprisingly powerful and leads to a unique solution to the dispersive sum rules relating Wilson coefficients and OPE data obtained in [1]. The corresponding OPE data fully agrees with and extends the results from integrability. The Wilson coefficients to order 1/$$ \sqrt{\uplambda} $$ λ can be summed into an expression whose structure of poles and residues generalises that of the Virasoro-Shapiro amplitude in flat space.
