Integrability in Yang-Mills theory on the light cone beyond leading order.

The one-loop dilatation operator in Yang-Mills theory possesses a hidden integrability symmetry in the sector of maximal-helicity Wilson operators. We calculate two-loop corrections to the dilatation operator and demonstrate that, while integrability is broken for matter in the fundamental representation of the SU(3) gauge group, for the ajoint SU(N(c)) matter it survives the conformal symmetry breaking and persists in supersymmetric N=1, N=2, and N=4 Yang-Mills theories.

Solution of the multi-Reggeon compound state problem in multicolor QCD.

We study the properties of the color-singlet compound states of Reggeized gluons in multicolor QCD using their relation with non-compact two-dimensional Heisenberg spin magnets. Applying the methods of integrable models, we calculate their spectrum and discuss the application of the obtained results to high-energy asymptotics of the scattering amplitudes in perturbative QCD.
