Description
I will discuss the behavior of large-charge correlation functions in planar N=4 SYM in the so-called Origin limits, where many cross ratios simultaneously approach zero - corresponding to corners of the positive kinematic region. Focusing on two-dimensional kinematics, I’ll explain how these limits can be explored using tools from cluster algebras and the hexagon formalism. I will also present a conjecture for the all-order behavior of correlation functions in this regime, based on a tilted version of the cusp anomalous dimension.
