Measurement of total and partial photon proton cross sections at 180 GeV center of mass energy
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 υ p 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.
