J/ Photoproduction and the Gluon Structure of the Nucleon
Abstract
Using short distance QCD methods based on the operator product expansion, we calculate the J/ photoproduction cross section in terms of the gluon distribution function of the nucleon. Comparing the result with data, we show that experimental behaviour of the cross section correctly reflects the x-dependence of the gluon distribution obtained from deep inelastic scattering.
