title = "Ratio of isolated photon cross sections in pp¯ Collisions at √s = 630 and 1800 GeV",
abstract = "The inclusive cross section for production of isolated photons has been measured in pp¯ collisions at √s = 630 GeV with the D0 detector at the Fermilab Tevatron Collider. The photons span a transverse energy (ET) range from 7-49 GeV and have pseudorapidity |η| < 2.5. This measurement is combined with the previous D0 result at √s = 1800 GeV to form a ratio of the cross sections. Comparison of next-to-leading-order QCD with the measured cross section at 630 GeV and the ratio of cross sections show satisfactory agreement in most of the ET range.",
