The squared amplitude has emerged as a remarkable object in both planar N=4 SYM and ABJM theory. In N=4, its duality with Wilson loops and correlators implies that the N-point, L-loop squared amplitude is captured by permutation-invariant f-graphs with N+L points. By analyzing the "cusp limit" of the correlator, we establish a new double-triangle graphical rule that bootstraps f-graph...

The Correlahedron, introduced by Eden, Heslop, and Mason, provides a positive geometric framework for computing correlation functions in maximally supersymmetric Yang–Mills theory. In this talk, I will review the underlying geometry and present recent developments, particularly the introduction of chambers, which partition the space into regions corresponding to distinct physical...

I will present the derivation of the AdS Virasoro-Shapiro amplitude for the scattering of gravitons in type IIA string theory on AdS4xCP3. This is achieved by combining the structure of the OPE in the AdS/CFT dual ABJM theory with an ansatz for the amplitude as a string worldsheet integral over single-valued polylogarithms. In this way we fix the first two curvature corrections, which satisfy...
