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.
