Integrability and the spectrum of two-dimensional fishnet CFT
Simon Ekhammar, Nikolay Gromov, Fedor Levkovich-Maslyuk +1
We formulate a closed set of equations for the spectrum of two-dimensional bi-scalar fishnet conformal field theory, comprising Baxter equations and quantisation conditions, which…

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…
