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
- Pulls (tThrown - tReconstructed)/σt (Reconstructed) when +/- 5 σ match to all thrown particles.
