The diffractive photoproduction of J/ψ mesons is measured with the H1 detector at the ep collider HERA using an integrated luminosity of 78 pb −1. The differential cross section dσ(γp → J/ψY )/dt is studied in the range 2 < |t| < 30 GeV2, wheret is the square of the four-momentum transferred at the proton vertex. The cro ss section is also presented as a function of the photon-proton centre-of-mass energy Wγp in threet intervals, spanning the range50 < Wγp < 200 GeV. A fast rise of the cross… CONTINUE READING
