摘要：

Using short distance QCD methods based on the operator product expansion, we calculate the J/psi 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.
