Abstract

Recent HERA data on the photoproduction of vector mesons are analysed within a "soft", dipole pomeron model. We argued that the data on σ^{γ→ J/ψ}_el is consistent with a soft pomeron, the apparent rapid increase resulting from the non-asymptotic effects due to the delayed asymptotics of σ_el with respect to σ_tot.
