文摘
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 . Differential cross sections are presented in the isolated-photon transverse-energy and pseudorapidity ranges and , and for jet transverse-energy and pseudorapidity ranges and , for exchanged-photon virtualities . 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.
