n3pi Cut Study
- Run 9003 (no EM background), ~5 MegaEvents, searching for γp→π+π+π-(n)
- Reconstructed Signal Combos (DCutAction_ThrownTopology, DCutAction_AllTruePID) (% is Signal Remaining)
- All is 34361 combos (events) of 59562 thrown n3pi in ~5 MegaEvent sample: 57.7% Acceptance
- +/- 5σ cut on Thrown <---> Detected matching for DCutAction_AllTruePID.
π+ PID
- 1D Pulls of skim tracks (tThrown - tReconstructed)/σt (Reconstructed)
- With DCutAction_ThrownTopology, DCutAction_AllTruePID @ +/- 5 σ matching.
- TBT is time-based tracking.
- For track time, order of preference is: BCAL, TOF, FCAL, TBT. Histograms only filled when that detector is selected.
- Large # of FCAL matches: perhaps track/TOF matching too restrictive?
- Large # of TBT tracks: no detector match
- Uncertainties used for pull (and PID) calculations are hard-coded.
- Histograms from DHistogramAction_PID
- 2D Pulls of π+'s (tThrown - tReconstructed)/σt (Reconstructed) with no cuts except +/- 5 σ thrown matching.
- Yellow line at pull = 0.0 just to guide the eye.
- low-θ tracks being matched to ST & BCAL hits indicates problems with hit-matching criteria.
- For track time, order of preference is: BCAL, TOF, FCAL, TBT. Histograms only filled when that detector is selected.
- Histograms from DHistogramAction_GenReconTrackComparison
