Ratio of isolated photon cross sections in p¯p Collisions at √s=630 and 1800 GeV

Ratio of isolated photon cross sections in p¯p Collisions at √s=630 and 1800 GeV
Ratio of isolated photon cross sections in p¯p Collisions at √s=630 and 1800 GeV
The inclusive cross section for production of isolated photons has been measured in p¯p collisions at √s=630GeV 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=1800GeV 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.

Abstract

The inclusive cross section for production of isolated photons has been measured in p¯p collisions at √s=630GeV 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=1800GeV 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.
