Soft Contribution to Quark-Quark Scattering Induced by an Anomalous Chromomagnetic Interaction

Abstract

We calculate the soft contribution to high energy quark-quark scattering that arises from an instanton-induced quark anomalous chromomagnetic moment. We demonstrate that this is a large contribution, which cannot be neglected for transverse momenta of a few GeV. We discuss the influence of this effect on inclusive particle production.
