Direct photon measurements by the D OE experiment

Description

We report a measurement of the cross section for production of isolated photons with transverse energy ET > 12 GeV in the central (absolute value of η < 0.9) and forward (1.6 < absolute value of η < 2.5) rapidity regions for bar pp collisions at center of mass energy √s = 1.8 TeV, using an integrated luminosity of 13 pb-1. The cross section is compared with a next-to-leading order (NLO) QCD calculation. We also present preliminary measurements of the center of mass scattering angle distribution and of the correlations between the rapidity of the photon and that of the leading jet in the event
