Description

Maximally supersymmetric four-dimensional Yang-Mills appear to be solvable in the planar limit. In particular, the non-perturbative spectrum of local operators can be calculated using the integrability-based Quantum Spectral Curve (QSC) formalism. However, the usefulness QSC extends beyond local operators. I will demonstrate how it can be used to understand what happens upon analytic continuation to negative spin, into the regime of horizontal Regge trajectories. Taking a weak coupling limit I will formulate a novel ”Asymptotic Baxter-Bethe Ansatz”: a set of equations, reminiscent of the Beisert-Eden-Staudacher equations, that controls the trajectories.
