  • Published 2013
Cross sections for elastic and proton-dissociative photop r duction of J/psi mesons are measured with the H1 detector in positron-proton collisions at HERA. The data were collected at ep centreof-mass energies √ s ≈ 318 GeV and√s ≈ 225 GeV, corresponding to integrated luminosities of L = 130 pb−1 andL = 10.8 pb−1, respectively. The cross sections are… (More)
