  1. Full Production Analysis so far… Saminder Dhaliwal 24th August 2005

  2. Resolution Z-> e+ e- Formula: (Reconstructed E – True E) / (0.1)*(sqrt [True E])

  3. Resolution at different Energy’s 50GeV < E < 70GeV 40GeV < E < 50GeV 150GeV < E 70GeV < E < 150GeV

  4. RMS and Sigma

  5. Producution so far • Filtering events, asking for • Lead Jet Pt > 30GeV, Second Jet Pt > 15GeV and eta gap between jets > 3.0 • Generate about 10 000 events (with filters) daily • Using about 40GB/day • Expect about 52 electrons of which 4-5 have Pt > 20GeV to be generated daily.

  6. No Cuts Reconstruced: 1 317 437 Matched Truth: 855 811

  7. First Cut: Pt > 20GeV, and “hasTrack” Reconstruced: 87 971 Matched Truth: 74 680

  8. Second Cut: is egamma object Reconstruced: 13 890 Matched Truth: 11 595

  9. Third Cut: isEM with TRT Reconstruced: 179 Matched Truth: 154

  10. Fake rate

  11. Conclusions • Need to explore etcone and EoverP cuts further. • Compare isEM analysis with and without TRT
