Abstract

Beisert et al. have identified an integrable SU (2, 2) quantum spin chain which gives the one-loop anomalous dimensions of certain operators in large N_c QCD. We derive a set of nonlinear integral equations (NLIEs) for this model, and compute the scattering matrix of the various (in particular, magnon) excitations.
