## Abstract The one‐loop planar dilatation operator of 𝒩 = 4 supersymmetric Yang‐Mills is isomorphic to the hamiltonian of an integrable __PSU__(2,2|4) spin chain. We construct the non‐linear sigma model describing the continuum limit of the __SU__(2|3) subsector of the 𝒩 = 4 chain. We explicitly i
