QCD—Instantons in e±P scattering

S. Moch, Andreas Ringwald, F. Schrempp

Abstract

We review recent theoretical results from our systematic study of QCD-instanton contributions to e±P processes, involving a hard momentum scale Q. The main issues are: the absence of IR divergencies due to a dynamical suppression of instantons with large size ρ>1/Q, the reliable calculability of instanton-induced amplitudes and our inclusive framework to systematically calculate properties of the I-induced multi-parton final state.
