Event selection

  1. di-jets from the cone jet-finder algorithm
  2. photon and jet are opposite in phi:
       cos (phi_gamma-phi_jet) < -0.8
  3. pt away side jet > 5GeV
  4. detector eta of the away side jet: |eta_jet_det| < 0.8
  5. data : L2e-gamma triggered events
  6. Monte-Carlo: emulated L2e-gamma triggered condition
  7. MC scaled to 3.164^pb based on Pythia luminosity (no fudge factors)

Figure 1a: Reconstructed photon candidate pt (L2e-gamma condition simulated in Monte-Carlo)

Figure 1b: Same as Fig. 1 on a linear scale and zoom into low pt

Figure 2: QCD Monte-Carlo yield to pp2006 data ratio

Figure 3: Prompt photon Monte-Carlo yield to pp2006 data ratio

Figure 4: Simulation yield vs. partonic pt (on a linear scale)
