DOIAbstract
Cross sections for elastic and proton-dissociative photoproduction of J/psi mesons are measured with the H1 detector in positron-proton collisions at HERA. The data were collected at ep centre-of-mass energies root s approximate to 318 GeV and root s approximate to 225 GeV, corresponding to integrated luminosities of L = 130 pb(-1) and L = 10.8 pb(-1), respectively. The cross sections are measured as a function of the photon-proton centre-of-mass energy in the range 25 < W-gamma p < 110 GeV. Differential cross sections d sigma/dt, where t is the squared four-momentum transfer at the proton vertex, are measured in the range vertical bar t vertical bar < 1.2 GeV2 for the elastic process and vertical bar t vertical bar < 8 GeV2 for proton diss...
