Photon and diphoton production at CDF and D0

PDF Version Also Available for Download.

Description

Measurements of prompt photon production in {anti p}p collisions at {radical}s = 1.8 TeV from the CDF and D0 experiments at Fermilab are presented. The measured inclusive isolated photon spectrum at CDF and D0 are used to test current parton distribution functions and NLO QCD predictions. No new resonance is found in the photon + jet mass spectrum from D0 which is consistent with NLO QCD predictions. The pseudorapidity distribution of the leading jet in photon events at CDF is used to constrain the parton distribution sets while the angular distribution is found to be better explained by a larger ... continued below

Description

Measurements of prompt photon production in {anti p}p collisions at {radical}s = 1.8 TeV from the CDF and D0 experiments at Fermilab are presented. The measured inclusive isolated photon spectrum at CDF and D0 are used to test current parton distribution functions and NLO QCD predictions. No new resonance is found in the photon + jet mass spectrum from D0 which is consistent with NLO QCD predictions. The pseudorapidity distribution of the leading jet in photon events at CDF is used to constrain the parton distribution sets while the angular distribution is found to be better explained by a larger Bremsstrahlung contribution. The soft diphoton spectrum is compared to NLO QCD predictions. The diphoton system P{sub T} is found to agree better with the LO shower monte-carlo prediction of Pythia than NLO QCD. Finally, the {gamma} + charm cross section is measured and compared to the LO Pythia prediction.
