Samples • 4 samples: – CONTAINED • QE • non. QE CC – UNCONTAINED • lepton exits detector • lepton fully contained

basic info • • S 12. 06. 17 FD MC Genie files (unswapped) 720, 000 events (2 E 23 POT) No rock events Oscillation assumptions: – 810 km – deltam 23^2 = 2. 35 E-3 – sin^2(2 theta 13) = 0. 1 – sin^2(2 theta 23) = 1 3

new variables • nick’s pid • susan’s E • best track (track with highest nick PID) used instead of longest track for lepton • still using: – Eremain = total Cal E – Cal E of tracks

• after oscillation equivalent of 400, 000 events: – 41% NC – 7% QE – 52% non. QE CC • Contained (all hits in FV): 191, 000 events – 57% NC/ 7% QE /36% non. QE CC • Uncontained: 209, 000 events – sample 1: lepton leaves detector (134, 000) • 13% NC/ 9% QE/ 78% non. QE CC – sample 2: lepton fully contained (75, 000) • 50% NC/ 3% QE/ 47% non. QE CC

QE • subdivide QE: – events with one (Kalman) track(51% contained QE) – events with two (Kalman) tracks: • where the 2 nd track is a 2 D track (22% of contained QE) • where the 2 nd track is a 3 D track (7% of contained QE)

single track QE: • • • n. Tracks=1 nick PID > 0. 4 best. Track. Length > 220 cm Eremain < 0. 035 (~70 Me. V) pe near vertex < 1200 final sample: 2% NC / 90% QE / 8% non. QE CC QE efficiency: ~40%

1 3 D track 1 2 D track QE: • • • n. Tracks = 2 nick PID > 0. 4 best track length > 220 cm d. E/dx of short track < 0. 0012 -0. 008*Eremain d. E/dx long track < 0. 0012 final sample: 1. 5% NC / 81% QE / 17. 5% non. QE CC QE efficiency: 8%

Contained: general CC • nicks PID > 0. 5 • best track length > 250 • Events aren’t in contained QE sample final sample: 7. 5% NC / 15. 5% QE / 77% non. QE CC QE efficiency: 64% non. QE CC eff: 65%

uncontained: sample 2 (FC mu) • • • longest track end inside FV best track length > 220 cm nick PID > 0. 44 0 < Z < 6000 abs(x, y) < 700 cm final sample: 5% NC / 4% QE / 91% non. QE CC QE eff: 19% / non. QE CC eff: 34%

E res: • Probably want different E estimator for each sample • Right now I look at 3 – – total cal (which varying prefactor) – susan’s E estimator – crude estimator involving range • (form: A*range + B*remaining Cal E, where B is same prefactor that centers total Cal, and A is whatever centers around 0)
