  1. WH->lnbb- Signal acceptance study • Contents • Current Study • Signal Sample • Lepton ID • Acceptance • Summary University of Tsukuba Y. Nagai

  2. Current Study • “WH->lvbb with 1fb-1” (CDFNOTE 8390) Signal Sample chgt1c: gen6 TopNtuple • Generator: Pythia • Event: WH->lnbb (l =e,m,t) • Higgs Mass: 120GeV • Number of Events: 297260

  3. Electron ID Electron Et > 20 GeV Isolated (Standard tight electron selection)

  4. Electron ID cf. Single Top Analysis (CDFNOTE 7863)

  5. Plug Electron ID Electron Et > 20 GeV Isolated (Standard tight electron selection)

  6. Plug Electron ID cf. Single Top Analysis (CDFNOTE 7863)

  7. Muon ID Muon Et > 20 GeV Isolated (Standard tight muon selection)

  8. Muon ID cf. Single Top Analysis (CDFNOTE 7863)

  9. Signal Acceptance 0 : Total event 1 : at least 1 lepton 2 : 2nd lepton veto 3 : at least 1 lepton w/ plug electrons 4 : 2nd lepton veto w/ plug electrons 0 : 297260 (100%) 1 : 68672 (23.1%) 2 : 68663 (23.1%) 3 : 78905 (26.5%) 4 : 78889 (26.5%) 14.9% improvement !!

  10. Summary • Lepton ID w/ plug electrons improve signal acceptance. • About 14.9% improvement are observed Next Step • Signal acceptance study • Lepton ID w/ plug muons • Event selection w/ MET Cut • Event selection w/ b-jet tagging • Jet Energy Correction Study at Top Ntuple Level
