Abstract

Nonlinear integral equation

Anomalous dimension

QCD

Super-Yang–Mills theory

Integrability

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.
