Structure Constants from Q-Systems and Separation of Variables
Till Bargheer, Carlos Bercini, Gabriel Lefundes +1
We introduce a novel method to compute structure constants from Q-functions in the scalar sector of planar N=4 super Yang-Mills (SYM) and related theories. The method derives from…

Exact Three-Point Functions in Superconformal Field Theories: Integrability vs. Localization
Gwenaël Ferrando, Shota Komatsu, Gabriel Lefundes +1
We propose an integrability approach for planar three-point functions at finite coupling in superconformal field theories obtained as orbifolds of $\…

Hexagons and the classical limit
Matheus Fabri, Gabriel Lefundes
In planar maximally supersymmetric Yang-Mills, we can compute three-point functions at weak coupling using the so-called hexagonalization formalism. The main objects in this framew…
