Run 2 Trigger Perfomance for emu Triggers ( CMS DP-2019/025)

The trigger efficiency for cross triggers has been measured using the Tag and Probe method by acquiring dilepton events having same flavour and opposite charge such that the invariant mass of the combination (tag and probe lepton) is consistent with the Z mass, in a dilepton mass window of 60-120 GeV. Details can be found the DPS Note CMS-DP-2019-025.

HLT_Mu23_TrkIsoVVL_Ele12_CaloIdL_TrackIdL_IsoVL_DZ: electron Leg Electron trigger efficiency as a function of the reconstructed electron transverse momentum (pT) in the full Run II dataset corresponding to an integrated luminosity of 138 fb-1 collected at √s=13 TeV. The efficiency is measured by tag-and-probe method (in Z→ee event) with respect to mva-based tight electron identification. The reconstructed electron pseudorapidity is restricted to the acceptance of the trigger path that is abs(η)<2.5 unless specified. The plotted uncertainties are statistical only. The last bin includes the overflow, i.e. also probes with pT >200 GeV. HLT_Ele12_CaloIdL_TrackIdL_IsoVL is the electron leg of the lowest threshold unprescaled cross-lepton trigger HLT_Mu23_TrkIsoVVL_Ele12_CaloIdL_TrackIdL_IsoVL_DZ that requires ET >12 GeV for the electron. The “DZ” requirement on the distance of closest approach in Z direction between the two electron tracks is ~ 99.5% efficient. Electron triggers are seeded via a logical OR of various level-1 trigger items. At the highest instantaneous luminosities, the level-1 ET threshold was higher than the HLT threshold contributing to the delayed turn-on of the efficiency as a function of pT. The efficiency is better in 2016 as the tracker alignment was much better in 2016 and also issues with new pixel detector were there in 2017 and 2018. [Get pdf version] Contact: Amandeep Kaur

At the highest instantaneous luminosities, the level-1 ET threshold was higher than the HLT threshold contributing to the delayed turn-on of the efficiency as a function of pT . The efficiency is better in 2018 as compared to 2016 and 2017 due to better muon reconstruction performance in 2018 and phase-I pixel performance was much better in 2018 than 2017. 2017 suffered from DCDC converter issues and extended commissioning period in the beginning of 2017.

HLT_Mu23_TrkIsoVVL_Ele12_CaloIdL_TrackIdL_IsoVL_DZ : muon leg Muon trigger efficiency as a function of the number of reconstructed vertices - that is used to estimate the amount of pile-up in the full Run II dataset corresponding to an integrated luminosity 138 fb-1 collected at √s=13 TeV. The efficiency is measured by tag-and-probe method (in Z→μμ event) with respect to cut-based tight muon identification and tight isolation. The reconstructed muon pseudorapidity is restricted to the acceptance of the trigger path that is abs(η)<2.4 unless specified. It is required that the reconstructed electron transverse momentum (pT) is at least 50 GeV to show the behaviour on the efficiency plateau in pT. The plotted uncertainties are statistical only. HLT_Mu23_TrkIsoVVL_CaloIdL_TrackIdL_IsoVL is the muon leg of the lowest threshold unprescaled cross-lepton trigger HLT_Mu23_TrkIsoVVL_Ele12_CaloIdL_TrackIdL_IsoVL_DZ that requires ET >23 GeV for the muon. The “DZ” requirement on the distance of closest approach in Z direction between the two muon tracks is ~ 99.5% efficient. Muon triggers are seeded via a logical OR of various level-1 trigger items. At the highest instantaneous luminosities, the level-1 ET threshold was higher than the HLT threshold contributing to the delayed turn-on of the efficiency as a function of pT . The efficiency is better in 2018 as compared to 2016 and 2017 due to better muon reconstruction performance in 2018 and phase-I pixel performance was much better in 2018 than 2017. As 2017 suffered from DCDC converter issues and extended commissioning period in the beginning of 2017. [Get pdf version] Contact: Amandeep Kaur
