## Abstract The oneβloop planar dilatation operator of π© = 4 supersymmetric YangβMills is isomorphic to the hamiltonian of an integrable __PSU__(2,2|4) spin chain. We construct the nonβlinear sigma model describing the continuum limit of the __SU__(2|3) subsector of the π© = 4 chain. We explicitly i
