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.5 pages, 4 figures, Presented at the X International Workshop on Deep Inelastic Scattering (DIS2002)High Energy Physics - Phenomenologytext
