Vacuum structure and high-energy scattering

Abstract

This short review deals with the manifestations of the vacuum structure of non-Abelian gauge theories in high-energy scattering. Specifically, it concentrates on instanton-induced hard scattering processes, both in the electroweak gauge theory and in QCD. Soft scattering processes in QCD and their connection to models of semi-hard vacuum fluctuations are also briefly discussed.
