LOOKING AT L1_SINGLEMU SEEDS TO CHECK THE EFFECT OF CSCTF HIGH OCCUPANCY

This analysis assesses the impact of CSCTF high occupancy on L1 SingleMu efficiency using datasets from specific runs. Results show good agreement between 2E33 and 3E33 menu runs, with detailed plots and conclusions presented.

  1. LOOKING AT L1_SINGLEMU SEEDS TO CHECK THE EFFECT OF CSCTF HIGH OCCUPANCY CSCTF meeting

  2. DATASET • Primary dataset is: • SingleMu • Run been used for the presented plots: • 2E33 menu runs are taking between (04th August - 12th August): • 172630 to 173198 • 3E33 menu runs are taking between (12th August – 21th August): • 173236 to 173692 • Non certified JSON file: • json_DCSONLY.txt_160404-173692 CSCTF meeting

  3. L1_SingleMu14 Efficiency • Efficiency plots using T&P method: • Offline Mu_Pt > 24GeV |η| ≤ 2.4 1.2 ≤ |η| ≤ 2.4 • Very good agreement • Between 2E33 & 3E33. CSCTF meeting

  4. L1_SINGLEMU14 EFFICIENCY (FOR 3E33 BAD RUNS ONLY) • Only 3E33 bad runs: • 173236, 173241, 173243, 173244, 173657, 173664 • Very good agreement • Between 2E33 & 3E33. CSCTF meeting

  5. L1_SingleMu16 Efficiency • Offline Mu_Pt > 24GeV |η| ≤ 2.4 1.2 ≤ |η| ≤ 2.4 • Very good agreement • Between 2E33 & 3E33. CSCTF meeting

  6. L1_SingleMu20 Efficiency • Offline Mu_Pt > 24GeV |η| ≤ 2.4 1.2 ≤ |η| ≤ 2.4 • Very good agreement • Between 2E33 & 3E33. CSCTF meeting

  7. CONCLUSION • We have not observe any high rate in L1_singleMu paths • We have a very good agreement in the efficiency results for the unprescaled L1_singleMu paths between 2E33 & 3E33 menu. • The change in CSCTF eta distribution shape it might be due to: • Increased L1 threshold • Change the prescale column for L1/HLT CSCTF meeting

  8. BACKUP CSCTF meeting

  9. HOT: CSCTF OCCUPANCY PLOT • Online DQM shifter: Observed a high trigger rate at high |eta|>2.1 last Friday in all runs after “173240” CSCTF meeting

  10. WHAT’S NEW IN FRIDAY’S RUNS • New deployment for HLT menu, we moved from 2E33 to 3E33 menu, where we • Increased L1 seed threshold • Changed the prescaled column • Some paths cover the entire eta region and some paths are |eta|<2.1 only. • Following the above it’s very complicated to try to conclude anything from pure inclusive occupancy plots, or csctf eta distribution which depend on a large mix of triggers. CSCTF meeting

  11. ONLINE DQM PLOTS • Run: • 173198 • 173241 Note: DQM plots filledafter HLT menu, we have to consider HLT prescals as well L1_3E33 Menu L1_2E33 Menu CSCTF meeting

  12. OFFLINE DQM: CSCTF ETA FOR DIFFERENT STREAMS SingleMu All muon thresholds Commissioning Dominant by low Pt • Run: • 173198 • 173241 Express stream only unprescaled L1 paths Express stream plots confirmed that In 3E33 menu, HLT_Mu paths increased The L1_Mu seed and HLT thresholds… CSCTF meeting
