The simplest event shape in $\mathcal{N}=4$ super Yang--Mills

Year: 2026

Type: preprint

Abstract: We study two-point event shapes in planar $\mathcal{N}=4$ super Yang--Mills, with source, sink and detectors given in terms of half-BPS scalars and their light transforms. Akin to local correlation functions, at order by order in perturbation theory, in the large charge limit, this event shape factorizes into the product of two octagons evaluated on the unit circle. Borrowing the octagon results, we study its behavior with respect to the coupling and the angle between the detectors.
