  Temporary hack I used to check jet ID usage in PAT

  • Selector.h: Added method printActiveCuts, useful for debugging selectors with many versions...
  • JetIDSelectionFunctor.h: Version for cvs - added fwd09 cuts, debugged over a few hundred jets
  • JetIDHelper.cc: New version for cvs - documented HF-AOD-nHitsIn90 bug and slightly improved a warning message

Efficiency plots

Inefficiencies of "Pure, loose" jet ID

Pure MC truth technique

See An for details - these are gen particles within the jet cone. New feature - no remapping done, x-axis shows the average pT_gen in each bin. Note: Having a few GeV of generated particles doesn't mean it's a real jet - at very low pT_gen the inefficiencies may be inflated by cases where noise dominates. This should be quite common near the jet reconstruction threshold, which is determined from the cell and tower thresholds.

Truth matched jets as a function of reconstructed pT

"Truth matched" means that at least 60% of the reconstructed (L2L3 corrected) energy is visible in stable particles (the same ones clustered into genJets) with dR<0.5 relative to the jet axis. To avoid biases, the efficiencies are measured in bins of the generated pT (same one used for the matching above), and then remapped to the reconstructed pT.

Tag & Probe technique

Statistics are a problem at low pT and in the HF.

BTW: the HFb plot is at 50-80 GeV.

Inefficiencies of n90hits>4 cut (2TeV MC)

As usual, I recommend the tag & probe method results and expect less bias in them. But their reach at low pT is insufficient for current running.

Inefficiencies due to cut on maximal EMF

This is in addition to the minimal EMF cut, whose inefficiencies are negligible here (and are detailed in the official jet ID page).

The inefficiencies are shown below for 5 detector regions:
HB is |eta|<1.0, BE is 1.0<|eta|<1.75, HE is 1.75<|eta|<2.6, EF is 2.6<|eta|<3.25, HF is 3.25<|eta|.
