Trigger Monitoring meeting

configuration for muon dq
Configuration for muon DQ
  • Online DQ: OHP & DQMD
    • Main histograms checked in online: kinematic distributions (pT, η, ϕ), hits information…
    • Main changes wrtp-p DQ: histograms from low-pt specialized algorithms instead of high-pt specialized algorithms (e.g: MuFastSteering_Muon MuFastSteering_900GeV)
  • Offline DQ:
    • Focus on chains based trigger efficiencies, measured with different methods: orthogonal triggers, looser muon triggers, tag & probe.
    • Strongly reply on trigger menu.
    • Primary triggers to be monitored:

mu4, mu6, mu10_MSonly, mu13_Msonly

    • Other important checks:
      • 2D eta-phi occupancy
      • L1 CTP consistency

online dq status
Online DQ status
  • What has been done:
    • Checked the reprocessed HLT distribution (run 210184), see an example below
    • Made the draft configuration file (*.xml)
  • Work to do:
    • Make the reference file if the merged file is available (L2 and EF)





offline dq status
Offline DQ status
  • What has been done:
    • Use the reprocessed ESD files to measure the trigger efficiency for the primary triggers (mu4, mu6, mu10_Msonly, mu13_MSonly)
    • Due to the low statistics, all the muon candidates were used without requiring any preselection (i.e without using orthogonal trigger or looser muon triggers), which may introduce some efficiency bias.
    • See efficiency plots in next slide.
  • Work to do:
    • For tag&probe method, we would need to use the J/ψ (instead of Z boson in pp collisions) mass constraint to select pure muon sample. Work still under going.
    • A sample (with larger statistics) is expected for us to evaluate the trigger efficiency, the 2D occupancy and make the reference.

Offline DQ --- 2D occupancy check

Need a sample with larger statistics for reference.
