1 Fake Jet Rejection: Sum Jt
The quantity: Calculated for AvgCellBkgrSubtr jets. Duplicate jets removed at the beginning. “Data” sets Hijing Hardcut b=2 Maximum Hijing particle within R = 0.4 < 30 GeV Total Hijing particle pt (pt > 2.5 GeV) < 30 GeV Pythia dijet events merged with Hijing b=2 hardcut J2, J3, and J4 All plots update from 1 week ago Re-reconstructed, re-analyzed. 12/4/2018 Cole -- Fake Jet Rejection w/ Sum Jt

2 SumJt vs Jet Et: Background
Purple points, line show profile and linear fit. 12/4/2018 Cole -- Fake Jet Rejection w/ Sum Jt

3 SumJt corrected vs Jet Et: Background
Subtracted off linear fit from previous slide 12/4/2018 Cole -- Fake Jet Rejection w/ Sum Jt

4 SumJt corrected: Background
Summed over all jet Et (background) 12/4/2018 Cole -- Fake Jet Rejection w/ Sum Jt

5 Background Rejection “Efficiency”
Good rejection at lower Et, decreasing with Et 12/4/2018 Cole -- Fake Jet Rejection w/ Sum Jt
