Abstract Scattering amplitudes in planar N $$ \mathcal{N} $$ = 4 super Yang-Mills theory exhibit singularities which reflect various aspects of the cluster algebras associated to the Grassmannians Gr(4, n) and their tropical counterparts. Here we inv

Abstract We study string corrections to one-loop amplitudes of single-particle operators O $$ \mathcal{O} $$ p in AdS 5 ×S 5. The tree-level correlators in supergravity enjoy an accidental 10d conformal symmetry. Consequently, one observes a partial

Abstract We describe a construction of the two-loop amplitude of four graviton supermultiplets in AdS5 ×S5. We start from an ansatz for a preamplitude from which we generate the full amplitude under the action of a specific Casimir operator. The ans

Abstract We discuss the string corrections to one-loop amplitudes in AdS5 ×S5, focussing on their expressions in Mellin space. We present the leading (α′)3 corrections to the family of correlators O 2 O 2 O p O p $$ \left\langle {\mathcal{O}}_2{\

Abstract We consider a set of half-BPS operators in N $$ \mathcal{N} $$ = 4 super Yang-Mills theory which are appropriate for describing single-particle states of superstring theory on AdS5 × S 5. These single-particle operators are defined to have

Abstract We consider α′ corrections to four-point correlators of half-BPS operators in N $$ \mathcal{N} $$ = 4 super Yang-Mills theory in the supergravity limit. By demanding the correct behaviour in the flat space limit, we find that the leading

Abstract Recently we conjectured the four-point amplitude of graviton multiplets in AdS5 × S5 at one loop by exploiting the operator product expansion of N $$ \mathcal{N} $$ = 4 super Yang-Mills theory. Here we give the first extension of those resu

Abstract We bootstrap loop corrections to AdS5 supergravity amplitudes by enforcing the consistency of the known classical results with the operator product expansion of N $$ \mathcal{N} $$ = 4 super Yang-Mills theory. In particular this yields much
