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.

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
BCAL
TOF
TBT
FCAL


  • 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
BCAL Pull vs p
BCAL Pull vs θ


TBT Pull vs p
TBT Pull vs θ


ST Pull vs p
ST Pull vs θ


TOF Pull vs p
FCAL Pull vs p


Alternate 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)
    • 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.

Very Alternate n3pi Cut Study (No BCAL)

  • 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.
