Instanton-Induced Cross-Sections in Deep-Inelastic Scattering
A. Ringwald, F. Schrempp
Abstract
We present our results for inclusive instanton-induced cross-sections in deep-inelastic scattering, paying in particular attention to the residual renormalization-scale dependencies. A ``fiducial'' kinematical region in the relevant Bjorken variables is extracted from recent lattice simulations of QCD. The integrated instanton-contribution to the cross-section at HERA corresponding to this fiducial region is surprisingly large: It is in the O(100) pb range, and thus remarkably close to the recently published experimental upper bounds.
