Optimizing Trigger Rates at 8 TeV for Enhanced Performance

Explore results for standard HLT table and PD definitions at 8 TeV in detail, including PD rates, trigger rates, issues, and strategies for lower lumi scenarios. Estimations for onia triggers at 8 TeV are also discussed. Learn how to address challenges such as merging PDs, adjusting HLT prescales, and introducing new quarkonia triggers without prescaling. Get insights into separating PD Mu into single and double categories for improved statistics at ~8 TeV.

Presentation Transcript

  1. PDs for 1E29 - 8E29 @ 7 TeV

  2. Outline • Results for standard HLT table and PDs definition for 8E29 • PD definition (slide 3-4) • PD rates (slide 5) • Trigger rates (slide 6-8) • Problems and strategy for lower lumi (slide 9-13) • Estimation for onia triggers @ 8E29 on ppMuX (slide 14-end)

  3. missing HLT_HT100U L1_HTT100 1, 1 missing HLT_BTagMu_Jet10U L1_Mu3QE8_Jet6 1, 1 no L1 available!

  4. missing HLT_Ele15_SiStrip_L1R L1_SingleEG8 1, 1

  5. Rates and correlations (Hz)

  6. HLT_L1MuOpen HLT_MinBiasPixel HLT_ZeroBias HLT_Mu3 HLT_Ele10_LW_L1R HLT_DoublePhoton5_eeRes_L1R HLT_SingleLooseIsoTau20 HLT_Jet30 HLT_IsoMu3

  7. Whit this “standard” trigger table and PD definition we will have problems of too small PDs at low lumi possibilities shown in next slides: 1) merging different PDs at low lumi (switching from one PD definition to another increasing the lumi → review the PDs distribution → change of data taking era) 2) lower the HLT prescales at low lumi

  8. 1) which PDs we can merge ? (same as slide 4)

  9. Merging jet/MET and single/double EGamma

  10. Merging jet/MET/Tau and single/double EGamma

  11. 2) NO HLT prescale, 1E29

  12. New quarkonia triggers (1) MuMonitor: HLT_L1MuOpen HLT_L1Mu Mu: HLT_Mu3 HLT_Mu5 HLT_Mu9 HLT_IsoMu3 HLT_L2Mu9 HLT_L2Mu11 HLT_L1Mu20 HLT_L1Mu14_L1SingleEG10 HLT_L1Mu14_L1SingleJet6 HLT_L1Mu14_L1ETM30 HLT_DoubleMu0 HLT_DoubleMu3 HLT_L1DoubleMuOpen New singleMu triggers: + HLT_Mu0Track_JPsi + HLT_Mu3Track_JPsi + HLT_Mu5Track_JPsi + HLT_Mu5Track_Ups New doubleMu triggers: + HLT_Mu0_MuOpen + HLT_Mu3_MuOpen + HLT_Mu5_MuOpen + HLT_Mu3_Mu0 All the new quarkonia triggers are NOT prescaled at HLT

  13. New quarkonia triggers: L1 seeds New singleMu triggers: + HLT_Mu0Track_JPsi L1SingleMuOpen || L1SingleMu0 + HLT_Mu3Track_JPsi L1SingleMuOpen || L1SingleMu0 || L1SingleMu3 + HLT_Mu5Track_JPsi L1SingleMu3 + HLT_Mu5Track_Ups L1SingleMu3 useless ?? New doubleMu triggers: All these L1 are not prescaled at 8E29 + HLT_Mu0_MuOpen L1DoubleMuOpen + HLT_Mu3_MuOpen L1DoubleMuOpen + HLT_Mu5_MuOpen L1DoubleMuOpen L1DoubleMuOpen + HLT_Mu3_Mu0

  14. Standard 8E29 with ppMuX 2 M of ppMuX events → only muons PDs have statistics ppMuX underestimate the rate !! +/- 0.1 Hz (was 19.5 in MinBias)

  15. Muon PD with new triggers (8E29, 7 TeV) 2 M of ppMuX events → only muons PDs have statistics +/- 0.1 Hz (was 9.0 Hz without onia triggers)

  16. ppMuX MinBias no onia: 9 Hz 19.5 Hz with onia: 13.8 Hz > 30 Hz We need to separate PD Mu into single and double at ~8E29
