Color-Singlet and Color-Octet Contributions to $J/\psi$ Photoproduction

Abstract

I discuss the impact of color-octet contributions and higher-order QCD corrections on the cross section for inelastic $J/\psi$ photoproduction. The theoretical predictions are compared with recent experimental data obtained at HERA.

LaTeX, 10 pages, 6 figures. Talk presented at the Workshops `QED and QCD in Higher Orders', Rheinsberg, Germany, April 21-26 and `Quarkonium Physics', Chicago, USA, June 13-15, 1996; to appear in the proceedings
