Level-1 E/Gamma and Muon performance on 2017 data

After the first long shutdown, the LHC has restarted at a centre-of-mass energy of 13~TeV. In 2016, the LHC achieved an instantaneous luminosity larger than $10^{34}$~$\mathrm{cm}^{-2}\cdot\mathrm{s}^{-1}$ and a peak average pile-up of more than 40. The CMS Level-1 trigger architecture has undergon...

description After the first long shutdown, the LHC has restarted at a centre-of-mass energy of 13~TeV. In 2016, the LHC achieved an instantaneous luminosity larger than $10^{34}$~$\mathrm{cm}^{-2}\cdot\mathrm{s}^{-1}$ and a peak average pile-up of more than 40. The CMS Level-1 trigger architecture has undergone a full upgrade in order to maintain and improve the trigger performance under these new conditions. It allows CMS to keep the trigger rate under control and to avoid a significant increase in trigger thresholds that would have a negative impact on the CMS physics program. Studies comparing the performance of the calorimeter trigger upgrade for electrons and photons during 2016 to the performance in 2016 are shown. The performance of the CMS L1 muon trigger has been measured using the EPS17 dataset and was compared to the results obtained for ICHEP16. Details of the Level-1 trigger algorithms may be found in the CMS Technical Design Report for the Level-1 Trigger upgrade: CERN-LHCC-2013-011, CMS-TDR-12 (2013).
