摘要：

We calculate corrections to the electroproduction cross section of J/psi at HERA energies arising from gluons in the photon interacting with gluons in the proton. These turn out to be sizable and may be isolated by suitable phase space cuts. Implications for the extraction of the gluon density of the proton at HERA are also discussed.
