  1. Z ττ Events Joshua Swanson Joshua Swanson

  2. Action Items • Investigate drop in electron efficiency.  Bring to attention  of tracking group and POG group.  Sridhara should give guidance • Use single electron and single muon triggers.  Add trigger matching • This has been added to my code but is not yet working properly. Joshua Swanson

  3. Electron Efficiency • The efficiency clearly drops without any ID cuts. The likely cause is the reconstruction of GSF electrons. Joshua Swanson

  4. Electron Efficiency • The efficiency drop is present in both the barrel and in the endcap. Joshua Swanson

  5. High Pt Efficiency drop. • The high pt threshold in gsf electrons is 35 GeV which seems to be where the drops begin in my plots. • Tried posting to the HN on electron efficiency discussion. Received no response. • Emailed directly to members of the group responsible for reconstruction of High Energy Electrons. Joshua Swanson
