title = "Diffractive J/ψ photoproduction as a probe of the gluon density",
abstract = "We use perturbative QCD, beyond the leading ln Q2 approximation, to show how measurements of diffractive J/ψ production at HERA can provide a sensitive probe of the gluon density of the proton at small values of Bjorken x. We estimate both the effect of the relativistic motion of the c and {\=c} within the J/ψ and of the rescattering of the c{\=c} quark pair on the proton. We find that the available data for diffractive J/ψ photoproduction can discriminate between the gluon distributions of the most recent sets of partons.",
