n3pi Cut Study (Shown at Physics Meeting)
- 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.
- PROBLEM: Way too many events lost due to PID cut.
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
Alternate n3pi Cut Study
- Run 9003 (no EM background), ~5 MegaEvents, searching for γp→π+π+π-(n)
- If no PID cut & very loose mass: 86.3% of signal, skim size = 46.6% (through grey: -3.0 < MM2 < 5.0, Tracking FOM +/- 5σ)
- If no PID cut & tighter mass: 83.8% of signal, skim size = 37.6% (through red: -2.0 < MM2 < 4.0, Tracking FOM +/- 5σ)
- Reconstructed Signal Combos (DCutAction_ThrownTopology, DCutAction_AllTruePID) (% is Signal Remaining)
- Originally had 34361 combos (events) of 59562 thrown n3pi in ~5 MegaEvent sample: 57.7% Acceptance
- +/- 5σ cut on Thrown <---> Detected matching for DCutAction_AllTruePID.
- All Reconstructed Combos (% is Skim Size)
Very Alternate n3pi Cut Study (No BCAL)
- Run 9003 (no EM background), ~5 MegaEvents, searching for γp→π+π+π-(n)
- If PID cut (no BCAL): 70.0% of signal, skim size = 21.7% (through blue: -2.0 < MM2 < 4.0, Tracking FOM +/- 5σ)
- 15% signal loss due to PID cut without BCAL, compared to 35% signal loss with BCAL
- Worse than above study (no PID cut: 83.8% of signal, skim size = 37.6%)
- Reconstructed Signal Combos (DCutAction_ThrownTopology, DCutAction_AllTruePID) (% is Signal Remaining)
- Originally had 34361 combos (events) of 59562 thrown n3pi in ~5 MegaEvent sample: 57.7% Acceptance
- +/- 5σ cut on Thrown <---> Detected matching for DCutAction_AllTruePID.
- BCAL time is ignored: for large-angle tracks, uses CDC (time-based tracking) time instead.
- All Reconstructed Combos (% is Skim Size)
Extremely Alternate n3pi Cut Study (No BCAL, KinFit)
- Run 9003 (no EM background), ~5 MegaEvents, searching for γp→π+π+π-(n)
- Reconstructed Signal Combos (DCutAction_ThrownTopology, DCutAction_AllTruePID) (% is Signal Remaining)
- Originally had 34361 combos (events) of 59562 thrown n3pi in ~5 MegaEvent sample: 57.7% Acceptance
- +/- 5σ cut on Thrown <---> Detected matching for DCutAction_AllTruePID.
- BCAL time is ignored: for large-angle tracks, uses CDC (time-based tracking) time instead.
- All Reconstructed Combos (% is Skim Size)
- Problem: No/oddly-shaped sidebands remain for sideband-subtraction analyses.
