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.
