Isolated photon cross section in the central and forward rapidity regions in p(p)over-bar collisions at root s=1.8TeV
A measurement of the cross section for production of single, isolated photons is reported for transverse energies in the range of 10-125 GeV for two regions of pseudorapidity, |η| < 0.9 and 1.6 < |η| < 2.5. The data represent 12.9 pb-1 of integrated luminosity accumulated in p̄p...

| Summary: | A measurement of the cross section for production of single, isolated photons is reported for transverse energies in the range of 10-125 GeV for two regions of pseudorapidity, |η| < 0.9 and 1.6 < |η| < 2.5. The data represent 12.9 pb-1 of integrated luminosity accumulated in p̄p collisions at √s = 1.8 TeV and recorded with the DO detector at the Fermilab Tevatron Collider. The background, predominantly from jets which fragment to neutral mesons, is estimated using the longitudinal shower shape in the calorimeter. In both pseudorapidity regions the cross section is found to agree with the next-to-leading order QCD prediction for 30 ≲ ET y ≲ 80 GeV. |
