Performance of the ATLAS muon triggers in Run 2

  title={Performance of the ATLAS muon triggers in Run 2},
  author={Atlas Collaboration},
  journal={Journal of Instrumentation},
The performance of the ATLAS muon trigger system is evaluated with proton-proton (pp) and heavy-ion (HI) collision data collected in Run 2 during 2015–2018 at the Large Hadron Collider. It is primarily evaluated using events containing a pair of muons from the decay of Z bosons to cover the intermediate momentum range between 26GeV and 100GeV. Overall, the efficiency of the single-muon triggers is about 68% in the barrel region and 85% in the endcap region. The pT range for efficiency…
