QCD at high-energies and two-dimensional field theory

Abstract:
Previous studies of high-energy scattering in QCD have shown a remarkable correspondence with two-dimensional field theory. In this paper we formulate a simple model in which this two-dimensional nature of the interactions is manifest. Starting from the (3+1)-dimensional Yang-Mills action and using the simplifications that occur for , we derive an effective theory which takes the form of a two-dimensional sigma-model. We show that our formulation is in agreement with known results from standard perturbation theory.- gauge field theory: SU(N)
