Abstract

Photon proton cross sections for elastic light vector meson production, σ el νp , inelastic diffractive production, σ nd νp , non-diffractive production, σ d νp , as well as the total cross section, σ tot νp , have been measured at an average υp center of mass energy of 180 GeV with the ZEUS detector at HERA. The resulting values are σ el νp = 18 ± 7 μb, σ d νp = 33 ± 8 μb, σ nd νp = 91 ± 11 μb, and σ tot νp 143 ± 17 μb, where the errors include statistical and systematic errors added in quadrature.
