Abstract:

Abstract: The performance of muon tracking, identification, triggering, momentum resolution,
and momentum scale has been studied with the CMS detector at the LHC using data collected at
√𝑠NN = 5.02 TeV in proton-proton (pp) and lead-lead (PbPb) collisions in 2017 and 2018, respectively,
and at √𝑠NN = 8.16 TeV in proton-lead (pPb) collisions in 2016. Muon efficiencies, momentum
resolutions, and momentum scales are compared by focusing on how the muon reconstruction
performance varies from relatively small occupancy pp collisions to the larger occupancies of pPb
collisions and, finally, to the highest track multiplicity PbPb collisions. We find the efficiencies of muon
tracking, identification, and triggering to be above 90% throughout most of the track multiplicity range.
The momentum resolution and scale are unaffected by the detector occupancy. The excellent muon
reconstruction of the CMS detector enables precision studies across all available collision systems.
