Update 08.24.2018 -- Run 9 pp: analysis flow

Just for reference, below is an overview of the neutral-triggered jet analysis flow.

  1. Tag pp events with either pi0 or gamma-rich triggers.
  2. Reconstruct jets in tagged events to obtain separate jet populations for each bin of trigger eT (9 - 11, 11 - 15, 15 - 20) and species (pi0, gamma-rich).
  3. Generate response matrix:
    1. Tag simulated events with charged hadron triggers, i.e. charged hadrons with the appropriate eta and eT.
    2. Construct jets in tagged events at both the particle (generated) level and detector (reconstructed) level.
    3. Match detector-level jets to particle-level jets to obtain the jet-matching efficiency and the response matrix.
  4. Using the appropriate response matrix, unfold each population of jets.
  5. Using the calculated gamma-rich purity, subtract the background from the unfolded gamma-rich populations to obtain the fully corrected gamma-direct spectra. 
  6. Take ratio of the fully corrected pi0 spectra to the fully corrected gamma-direct spectra.
