We construct Separation of Variables (SoV) inspired expressions
for the SL(2) sector of planar N = 4 supersymmetric Yang-Mills,
valid to all orders in perturbation theory up to wrapping corrections. Specifically, we identify simple universal
measures that make Q-functions of operators with different spin
vanish at all orders in perturbation theory before wrapping correc-
tions. In analysing this rank-one sector, we uncover generalizations
to the usual assumptions considered in the Separation of Variables
framework that may serve as guidelines for extending this formalism
to other integrable models.
