Latest Cutflow C0: GRL C1: Trigger C2: Primary vertex with ntracks > 4 C3: Electron/muon overlap, larVeto C4: Jet cleaning C5: Lepton Veto C6: njets >= 4 with eta < 2.3 and |jvf| > 0.75 C7: ptmiss significance > 8 C8: MT < 70GeV C9: Sum ET < 500GeV C10: >= 1 bjet

C11: Tau n ≥ 1, BDTScore > 0.72 C12: Trigger matched tau n ≥ 1 and pT >= 40GeV C13: MC tau object match

Missing pT Significance vs BDTScore

Correlation in the background area…. variable pair is unsuitable for ABCD….

After C6 At end of cutflow

mT vs Sum ET

After C6 At end of cutflow

Still missing ~ 240 files but not looking good
