Presentation Transcript

  1. Top Mass Using e-tagging of B Jets • Basic cuts (same as PRD) • Neural Networks(same as PRD) • e-tagging(CTool) • Mass from double tagged events using PRD sample(~100 events) • Possible larger sample (~300,000) used in Eunil’s thesis C. Hebert 22 October 99

  2. E-tagging Efficiencies and Backgrounds • Next: Find efficiencies & BG to a few % • ttbar Alljets MC fully Geanted + hand scan • bbar MC + hand scan check • background --> QCD Data

  3. Status • Re-GEANTed old HERWIG • Tested analysis chain with this sample • Scanning setup on CD’s Onyx computer is ready • Full GEANT is running at FSU (Brian)

  4. Efficiency • Probability{electron is found| e from a b or c quark in the CCEM region with E>15 GeV and has a CDC track}

  5. HTML Sites • On d02ka/d0mino file:/prj_root/760/infr_1/youssef/integration/scri/types/packages/d0/eventdisplays/event_display_stagging.html • www-d0.fnal.gov/~hebertcl
