October 19th, 2012

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

  • 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)

muFastSteering_900GeV_AbsPt

  • 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.
