  1. Muon DQ setup for p-Pb running Y. Yamazaki, T. Kishimoto, L. Yuan Kobe University October 19th, 2012 Trigger Monitoring meeting

  2. 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

  4. 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) muFastSteering_Muon_AbsPt muFastSteering_900GeV_AbsPt p-p p-pb

  5. 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.
