QCD-Instantons at HERA

Abstract

A ``fiducial'' kinematical region for our calculations of instanton (I)-induced processes at HERA within I-perturbation theory is extracted from recent lattice simulations of QCD. Moreover, we present the finalized I-induced cross-sections exhibiting a strongly reduced residual dependence on the renormalization scale.
