Resumen
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 26 GeV and 100 GeV. 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 determination is extended by using muons from decays of
J/ψ mesons, W bosons, and top quarks. The performance in HI collision data is measured and
shows good agreement with the results obtained in pp collisions. The muon trigger shows uniform
and stable performance in good agreement with the prediction of a detailed simulation. Dedicated
multi-muon triggers with kinematic selections provide the backbone to beauty, quarkonia, and
low-mass physics studies. The design, evolution and performance of these triggers are discussed in
detail.
