  1. SUSY DILEPTON TRIGGER MONITORING M.Rossi (Udine University) Multilepton Meeting

  2. RUNS • ONLINE bits required to be good: CLC,L1T,L2T,L3T,CAL,COT,CMU,CMP,CMX,SMX • OFFLINE bits required to be good: COT,CAL,CMU,CMP,CMX • RUN < 179056, when COT problems started (February 13, 2004) 938 RUNS, 220 pb-1 Multilepton Meeting

  3. NOW CONSIDERING RUNS • 782 runs, 140 pb-1 • Time range: 2002.03 – 2004.02 • Trigger table range: PHYSICS_1_01_v1 / PHYSICS_2_01_v4 TRIGGER PATHS • CEM4_CEM4 (DIELECTRON_CENTRAL_4) • CEM4_CMUP4 • CEM4_CMX4 • CMUP4_CMUP4 • CMUP4_CMX4 Multilepton Meeting

  4. MONITORING VARIABLES R events collected by the trigger path having one of the corresponding reconstructed lepton (per trigger path: R11st lepton, R22nd lepton) Q events, that have two reconstructed leptons, not collected by the corresponding trigger path Rate events collected by trigger path over the luminosity of the run Multilepton Meeting

  5. CEM4_CMUP4 run 168000-168086 run 144628-150799 run 163113-163136 run 167824-167847 Multilepton Meeting

  6. CEM4_CMX4 run 152942-152953 Multilepton Meeting

  7. CEM4_CEM4 Multilepton Meeting

  8. CMUP4_CMX4 Multilepton Meeting

  9. CMUP4_CMUP4 Multilepton Meeting

  10. STEP run 168000-168086 PHYSICS_1_05_v7 VS PHYSICS_1_05_v8 • New SUSY Dilepton paths to use 4 GeV CMU • rather than restricting to CMUP • Lower CEM to 4 GeV to match other SUSY paths • New SUSY Dilepton backup paths all Q distributions becomes less stable Multilepton Meeting

  11. STEP run 144628-150799 PHYSICS_1_01_v7 VS PHYSICS_1_02_v3 • Tighter CMX extrapolation • (new version of L1 trigger for all CMX paths) • Cut on CES in L2 big step in rate distributions for CEM paths Multilepton Meeting

  12. STEP run 167824-167847 PHYSICS_1_05_v6 VS PHYSICS_1_05_v7 • Add COT and Silicon data compression to • reconstruction trigger in Level 3 for good • Add MONITOR_DAQ_ERROR_v1 • to find problems like BC miss match • using new filter all rate distributions becomes less stable Multilepton Meeting

  13. STEP run 163113-163136 PHYSICS_1_04_v9 VS PHYSICS_1_05_v1 • Nearly all electron and photon L3 triggers • tightened • sinθ from track for electrons • New EM filter in 4.8.4 as 3-tower had/em step in R distributions for CEM paths Multilepton Meeting

  14. STEP run 152942-152953 PHYSICS_1_02_v7 VS PHYSICS_1_03_v1 Add scintillator CSX to all CMX L1 triggers step in R and rate distribution for CEM4_CMX4 path Multilepton Meeting

  15. Summary R: locally flat distribution that reflects changes in the trigger table  locally stable trigger behaviuor NEXT 782 runs considered  complete 938 runs Multilepton Meeting

  16. BACKUPDOWNSTREAMAPPROACH • For each TRIGGER PATH (T.P.) count: N : # evts selected by the T.P. N1: # evts with offline lepton 1 N2: # evts with offline lepton 2 • In ideal conditions R=1 (R~purity) • For each lepton “type”, expect R values from different T.P. comparable and stable in time R1≡ N1/N and R2 ≡ N2/N Multilepton Meeting

  17. BACKUPUPSTREAM APPROACH • N12 ≡ events with lepton 1 && lepton 2 reconstructed offline level • N0 ≡ events failing the i-th T.P. Qi ≡ N0/NAB • In ideal conditions Qi = 0 Multilepton Meeting
