CDF plots from the photon + 2-jet analysis

We measure the mass, tranverse energy and angular distributions in photon and two jet events and compare them to theoretical predictions from Owens leading order calculation. This data is particularly sensitive to contributions from soft radiations of either a jet or a photon.

• pho_2jet_cons_en.ps---Measure of the double scatter background using the difference in energy conservation between QCD and double scatter events.
• pho_2jet_Mass_X.ps---Mass and X=Et/Mass distributions for the photon and both jets.
• pho_2jet_Et.ps---Energy spectra for the photon and both jets.
• pho_2jet_angle.ps---Angular separation between the photon and both jets.
• pho_2jet_Mass_X_res.ps---Residuals of Mass and X=Et/Mass distributions compared to Owens LO QCD and variations on the theory.
• pho_2jet_Et_res.ps---Residuals of the Energy spectra compared to Owens LO QCD and variations on the theory.
• pho_2jet_angle_var.ps---Angular separation between the photon and both jets compared to variations on the LO QCD prediction.
