摘要：
We describe recent perturbative QCD calculations of diffractive J/psi and open <c(c)over bar> production at HERA and show that they offer a sensitive probe of the gluon density at small x. We discuss briefly the Q(2) and beta dependence of the cross section and show that estimates of the higher order corrections indicate a strong enhancement of the open charm production.
