Presentation Transcript

  1. Status: WW,ZZ->H->  Catalin, Kevin, Tony, Dovid

  2. Monte Carlo • Partially solved the MC issue: • Random gen. seed not used • Generate all MC in one job • OK – given that this is not full simulation • Real-simulation sample available? • Generated 50k events WW/ZZ ->Higgs • Last week – Dovid Skversky joined: • REU student – will work on these studies exclusively.

  3. HEPG-level plots Pt and  of the positive tau Higgs Mass = 130 GeV

  4. Leptons and Photons Require Isolated Electron Muon, or Photon

  5. JetET ET(j1)>35 GeV ET(j2)>20 GeV

  6. Jet Pseudorapidity

  7. Which jet Et? • Two kinds of jets in the atlfast ntuple: • JET(reconstructed jets) • JETB(reconstructed jets calibrated with atlfastB) Leading jet 2nd Leading jet

  8. JET vs JETB

  9. Erik’s parametrization • Considered all jets with Et<300 GeV and ||<2.8 • Example: 50 GeV threshold

  10. Efficiency vs Threshold • Thresholds from 30 GeV to 200 GeV • Exponential decrease • What about lepton triggers: • Only 2 studied: MU20 and EM25I • Efficiency: 26% • Overlap? • Only the 50 GeV jet thresh: • Overlap is 25% with lep trig. • Need more study

  11. Plans for the next meeting • Compare to Bruce results, for the same cuts. • Find out about full-simulation samples • Study the triggers in more detail. Also: • Include missing Et • ‘tau’ jets • Look at backgrounds, if available
