15. A hidden permutation symmetry of squared amplitudes in N=4/ABJM theory

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...

16. Positive Geometry and Leading Singularities in Correlation Functions

Dr C. Kuo

01/10/2025, 11:10

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...

17. Correlators with BPS bound states and the double-particle limit of 5pt Amplitudes in AdS5xS5

Dr F. Aprile

18. Adventures at Five Points

Dr T. Bargheer

01/10/2025, 13:00

I will consider correlation functions of five scalar BPS
operators in N=4 SYM theory from various perspectives, and
present recent results on their computation.

19. The AdS4 × CP3 Virasoro-Shapiro Amplitude

Dr T. Hansen

01/10/2025, 13:40

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...
