- Abstract
- The production of isolated high-energy photons accompanied by jets has been measured in deep inelastic ep scattering with the ZEUS detector at HERA, using an integrated luminosity of 326pb <sup>-1</sup>. Measurements were made for exchanged photon virtualities, Q <sup>2</sup>, in the range 10 to 350GeV <sup>2</sup>. The photons were measured in the transverse-energy and pseudorapidity ranges 4<ETγ<15GeV and -0.7<η <sup>γ</sup><0.9, and the jets were measured in the transverse-energy and pseudorapidity ranges 2.5<ETjet<35GeV and -1.5<η <sup>jet</sup><1.8. Differential cross sections are presented as functions of these quantities. Perturbative QCD predictions give a reasonable description of the shape of the measured cross sections over most of the kinematic range, but the absolute normalisation is typically in disagreement by 20-30%. © 2012 Elsevier B.V.
