Abstract: (Elsevier)
We study high-energy scattering in two-dimensional quantum chromodynamics in the 1/ N colour expansion. To first order, high-energy forward scattering amplitudes are power-behaved with the factorization, signature and exchange degeneracy properties found in dual Regge models. Backward scattering has deviations from naive quark power-counting rules which are related to the form factor and “Regge” behaviours. In the second order of 1/ N colour vacuum exchange diagrams do not give a new Pomeron singularity, but do break exchange degeneracy.- GAUGE FIELD THEORY
