2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/207364A 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 p-pbar collisions at sqrt{s} = 1.8 TeV and recorded with the D0 detector at the Fermilab Tevatron Collider.9 pages, submitted to Physical Review Letters, http://d0sgi0.fnal.gov/~womersle/photon_prl_preprint.psHigh Energy Physics - Experimenttext
