Ele23 leg efficiency of HLT_Ele23_Ele12_CaloIDL_TrackIdL_IsoVL path as a function of SC ET The efficiency for the Ele23 leg of the HLT_Ele23_Ele12 trigger as a function of supercluster (SC) EΤ for ECAL barrel (left) and ECAL endcap (right) presented for 2016 and 2017 data. Due to the presence of a high pT electron in the event, the L1 threshold on the second electron is lowered to 5 GeV in 2017 which effectively removes L1 turn on effects from the measured efficiency. The rate of the trigger in 2017, corresponding to Run Number 302596 (Average pileup=38) is 8.53 Hz, whereas in 2016 corresponding to Run Number 283885 (Average pileup =43), is 24.83 Hz. We see 70% rate reduction in 2017 with the new pixel detector for a small (1-2%) loss in efficiency. [Get pdf version EB] [Get pdf version EE] Contact: Bhawna Gomber |

Ele23 leg efficiency of HLT_Ele23_Ele12_CaloIDL_TrackIdL_IsoVL path as a function of number of vertices The efficiency for the Ele23 leg of the HLT_Ele23_Ele12 trigger as a function of the number of offline vertices (with SC ET > 50 GeV, SC abs(η) < 2.5) for ECAL barrel (left) and ECAL endcap (right) presented for 2016 and 2017 data. Due to the presence of a high pT electron in the event, the L1 threshold on the second electron is lowered to 5 GeV which effectively removes L1 turn on effects from the measured efficiency.

Efficiency of the pixel match filter for HLT_Ele23_Ele12_CaloIDL_TrackIdL_IsoVL path as a function of SC ET The efficiency of the pixel match filter (where we require supercluster to have 3 matching hits in the pixel detector) for the Ele23 leg of the HLT_Ele23_Ele12 trigger as a function of supercluster EΤ for ECAL barrel (left) and ECAL endcap (right) presented for 2017 data and MC. Due to the presence of a high pT electron in the event, the L1 threshold on the second electron is lowered to 5 GeV which effectively removes L1 turn on effects from the measured efficiency. DCDC converters that provide LV (VA/VD) for pixel detector modules start failing on October 5, 2017. The efficiency is shown for different pixel detector conditions, commissioning period (run<=302026), Nominal WP Pre Oct 5th (302026 <run<304366), and Nominal WP Post Oct 5th (run>=304366). By comparing periods with and without the DCDC issue, the effect on the Egamma trigger performance is estimated to be a few percent, ~1-2%.
