Fully-Hadronic Triggers
 The fully hadronic triggers are designed to collect events characterized by their large jet and b tagged jet multiplicity. Several studies can benefit from these triggers, including ttH production measurements, where H decays to a bb pair, measurements of tt production, and search for charged Higgs bosons, H++, decaying into tb quarks, all in the fully hadronic final state. The trigger efficiency measurement is done using the orthogonal trigger method. Details are in the DP note.

Electron+HT and Electron+Jet Triggers

The following plots describe the performance in the LHC Run-2 of two electron+jets cross-triggers, specifically an “electron + HT ” trigger and “electron + 1 jet” trigger. Details can be found in the DP note.

L1+HLT efficiency of the logical OR of the Ele28_HT150 and Ele32 triggers (red) and the Ele32 trigger (blue) in 2017 data, as a function of the offline electron pT (left) and the number of jets reconstructed offline (right). The efficiencies are measured in a sample of emu events collected by an independent single-muon trigger. Events are selected offline requiring the presence of a muon firing the single-muon trigger, a reconstructed electron with pT > 30 GeV, abs(eta) < 2.5, and passing the tight identification criteria, and at least four jets with pT > 30 GeV and abs(eta) < 2.4. For these events, the introduction of the cross-trigger improves the overall efficiency from 79% (single-electron trigger) to 83% in 2017 data. In the plot on the left-hand (right-hand) side, the offline cut on the electron pT (number of reconstructed jets), indicated by the gray dashed line, is loosened in order to show the turn-on of the trigger efficiencies.

Efficiency of fully hadronic triggers measured in the 2016 dataset in events collected with an independent single muon trigger as a function of the offline reconstructed HT and the pT of the sixth offline reconstructed jet. Efficiency of above 99% is achieved in data above the HT > 500 GeV, and found to be compatible with simulations.

Efficiency of fully hadronic triggers measured in the 2017 dataset in events collected with an independent single muon trigger, as function of HT and the pT of the sixth offline reconstructed jet. Efficiency of above 95% is achieved in data above the HT > 500 GeV, and found to be compatible with simulations within a 5%. The lower efficiency observed in 2017 is due to detector-related issues affecting part of the 2017 data-taking period (failure of DCDC converters in the CMS pixel system). The inefficiency is observed in the low HT region, which is driven by the lower HT thresholds of double and triple b tagged jets triggers, which are more sensitive to pixel failures.

Performance of top triggers in Run 2 ( CMS DP-2019/026)

The fully hadronic triggers are designed to collect events characterized by their large jet and b tagged jet multiplicity. Several studies can benefit from these triggers, including ttH production measurements, where H decays to a bb pair, measurements of tt production, and search for charged Higgs bosons, H++, decaying into tb quarks, all in the fully hadronic final state. The trigger efficiency measurement is done using the orthogonal trigger method. Details are in the DP note.


Eff_Ht_SignalOR_2016.png Eff_pt6thJet_SignalOR_2016.png Jet trigger efficiency in 2016
Efficiency of fully hadronic triggers measured in the 2016 dataset in events collected with an independent single muon trigger as a function of the offline reconstructed HT and the pT of the sixth offline reconstructed jet. Efficiency of above 99% is achieved in data above the HT > 500 GeV, and found to be compatible with simulations.

Eff_Ht_SignalOR_2017.png Eff_pt6thJet_SignalOR_2017.png Jet trigger efficiency in 2017
Efficiency of fully hadronic triggers measured in the 2017 dataset in events collected with an independent single muon trigger, as function of HT and the pT of the sixth offline reconstructed jet. Efficiency of above 95% is achieved in data above the HT > 500 GeV, and found to be compatible with simulations within a 5%. The lower efficiency observed in 2017 is due to detector-related issues affecting part of the 2017 data-taking period (failure of DCDC converters in the CMS pixel system). The inefficiency is observed in the low HT region, which is driven by the lower HT thresholds of double and triple b tagged jets triggers, which are more sensitive to pixel failures.

The following slides describe the performance in the LHC Run-2 of two electron+jets cross-triggers, specifically an “electron + HT ” trigger and “electron + 1 jet” trigger. Details can be found in the DP note.

L1+HLT efficiency of the logical OR of the Ele28_HT150 and Ele32 triggers (red) and the Ele32 trigger (blue) in 2017 data, as a function of the offline electron pT (left) and the number of jets reconstructed offline (right). The efficiencies are measured in a sample of emu events collected by an independent single-muon trigger. Events are selected offline requiring the presence of a muon firing the single-muon trigger, a reconstructed electron with pT > 30 GeV, abs(eta) < 2.5, and passing the tight identification criteria, and at least four jets with pT > 30 GeV and abs(eta) < 2.4. For these events, the introduction of the cross-trigger improves the overall efficiency from 79% (single-electron trigger) to 83% in 2017 data. In the plot on the left-hand (right-hand) side, the offline cut on the electron pT (number of reconstructed jets), indicated by the gray dashed line, is loosened in order to show the turn-on of the trigger efficiencies.

njets_ele28_ht150_OR_ele32_datamc_2017_2018.png Electron + HT trigger (2017+2018)
L1+HLT efficiency of the logical OR of the Ele28_HT150 and Ele32 triggers, for data (solid markers) and MC (empty markers), in 2017 (blue) and 2018 (red), as a function of the number of jets reconstructed offline. The efficiencies are measured in a sample of emu events collected by an independent single-muon trigger. Events are selected offline requiring the presence of a muon firing the single-muon trigger, a reconstructed electron with pT > 30 GeV, abs(eta) < 2.5 and passing the tight identification criteria, and at least four jets with pT > 30 GeV and abs(eta) < 2.4. The lower efficiency observed in 2017 is due to detector-related issues affecting part of the 2017 data-taking period (failure of DCDC converters in the CMS pixel system).

Left: L1+HLT efficiency of the logical OR of the Ele30_Jet35 and Ele32 triggers (red) and the Ele32 trigger (blue) in 2018 data, as a function of the offline electron pT . Right: L1+HLT efficiency of the logical OR of the Ele30_Jet35 and Ele32 triggers, as a function of the offline electron pT in 2018 data (solid markers) and simulation (empty markers). The efficiencies are measured in a sample of emu events collected by an independent single-muon trigger. Events are selected offline requiring the presence of a muon firing the single-muon trigger, a reconstructed electron with pT > 32 GeV, abs(eta) < 2.5, and passing the tight identification criteria and at least one jet with pT > 40 GeV and abs(eta) < 2.4. For these events, the introduction of the cross-trigger improves the overall efficiency from 86% (single-electron trigger) to 88% in 2018 data. In both plots, the offline cut on the electron pT , indicated by the gray dashed line, is loosened in order to show the turn-on of the trigger efficiencies.
