Abstract

We discuss how the stability of the theoretical prediction for exclusive J/ψ photoproduction has been improved through a systematic taming of the known MS coefficient functions by accounting for a formally power suppressed, but numerically significant, correction encoded within a Q0 cut. The phenomenological implications of this will be emphasised meaning, ultimately, the possibility to include the exclusive data into a global fitter framework to provide constraints on the small x gluon.
