Z ττ Events

This report highlights the investigation into the drop in electron efficiency observed without ID cuts, emphasizing the potential role of GSF electron reconstruction issues. Joshua Swanson notes that the efficiency decline is evident in both barrel and endcap regions, particularly as the high pt threshold reaches 35 GeV. Efforts to communicate findings included posting on relevant forums and directly emailing group members responsible for high-energy electron reconstruction. Guidance from experienced group members, such as Sridhara, is needed to resolve outstanding issues with trigger matching in the code.

  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
