“…Previous experiments, at center-of-mass energies of both 630 GeV [2] and 1800 GeV [3,4], have reported photon production in excess of next-to-leading-order (NLO) QCD predictions at low transverse energies ͑E g T & 30 GeV͒. This disagreement with data could result from gluon radiation not included in NLO calculations [5] or because the parton distributions are not well known [6].…”

“…Comparing data to the prediction shows some disagreement for all four regions. Similar disagreements were seen earlier by UA2 [13], CDF [14] and D0 [15]. The disagreement cannot be completely accounted for by the overall uncertainty.…”

“…Photon production at large transverse momenta is a classical hadron collider observable. It was measured already at early experiments at the ISR [1][2][3] and SppS [4,5] colliders, followed by precision studies at the Tevatron [6,7] and by the ATLAS [8][9][10] and CMS [11,12] experiments at the LHC. In addition to these measurements of inclusive photon production, more exclusive photon-plus-jet final states were also investigated at the Tevatron [13,14] and by ATLAS [15][16][17] and CMS [12,[18][19][20].…”
