• Opis:
  ZEUS Collaboration;
  The photoproduction of isolated photons, both inclusive and together with a jet, has been measured with the ZEUS detector at HERA using an integrated luminosity of 374 pb^{−1}. Differential cross sections are presented in the isolated-photon transverse-energy and pseudorapidity ranges 6 < E^γ_T < 15 GeV and −0.7 < η^γ < 0.9, and for jet transverse-energy and pseudorapidity ranges 4 < E^{jet}_T < 35 GeV and −1.5 <η^{jet} < 1.8, for exchanged-photon virtualities Q^2 < 1 GeV^2. Differential cross sections are also presented for inclusive isolated-photon production as functions of the transverse energy and pseudorapidity of the photon. Higher-order theoretical calculations are compared to the results.;
  We appreciate the contributions to the construction, maintenance and operation of the ZEUS detector made by many people who are not listed as authors. The HERA machine group and the DESY computing staff are especially acknowledged for their success in providing excellent operation of the collider and the data-analysis environment. We thank the DESY directorate for their strong support and encouragement. We also thank M. Fontannaz, G. Heinrich, A. Lipatov, M. Malyshev and N. Zotov for providing assistance and theoretical results. Funded by SCOAP3
