Abstract
Using short distance QCD methods based on the operator product expansion, w e calculate the J/psi photoproduction cross section in terms of the gluon d istribution function of the nucleon. Comparing the result with data, we sho w that experimental behaviour of the cross section correctly reflects the x -dependence of the gluon distribution obtained from deep inelastic scatteri ng.
