title = "Probing the gluon structure of the proton with HERA",
abstract = "We study the production of ψ mesons in ep collisions and argue that ψ's form the ideal experimental signature for directly identifying the {"}anomalous{"} gluon structure of the photon. The observation is of relevance to studies of the nucleon structure functions using HERA and to high energy γ-ray astronomy.",
