Description
I will discuss exclusive J/psi and eta_c production in electron-proton collisions, mediated in the lowest order QCD by 2- and 3-gluon exchanges. In the recently developed model, we relate the amplitudes for those processes to the correlators of the quark current in the light-cone wave function of the proton. We obtain new estimates of eta_c cross-section at the energy W~10 GeV.
