Higher-Point Correlators in N=4 SYM: Ten-Dimensional Null Polygons
Till Bargheer, Albert Bekov, Carlos Bercini +1
We consider higher-point generalizations of the "octagon" large-charge four-point function in planar N=4 super Yang-Mills theory. These n-point polygon correlators are defined as t…
Higher-Point Correlators in N=4 SYM: Generating Functions
Till Bargheer, Albert Bekov, Carlos Bercini +1
We construct generating functions of five- and six-point correlators up to two loops at weak 't Hooft coupling in planar N=4 SYM. These generating functions unify the correlators o…
Orthogonality of Q-Functions up to Wrapping in Planar N=4 Super Yang-Mills Theory
Till Bargheer, Carlos Bercini, Andrea Cavaglià +2
We construct orthogonality relations in the Separation of Variables framework for the sl(2) sector of planar N=4 supersymmetric Yang-Mills theory. Specifically, we find simple univ…
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…
Wilson Loops with Lagrangians: Large Spin OPE and Cusp Anomalous Dimension Dictionary
Till Bargheer, Carlos Bercini, Bruno Fernandes +2
In the context of planar conformal gauge theory, we study five-point correlation functions between the interaction Lagrangian and four of the lightest single-trace, gauge-invariant…
