Performance of the reconstruction and identification of high-momentum muons in proton-proton collisions at $\sqrt{s} =$ 13 TeV

Understand

The CMS detector at the LHC has recorded events from proton-proton collisions, with muon momenta reaching up to 1.8 TeV in the collected dimuon samples.

• These high-momentum muons allow direct access to new regimes in physics beyond the standard model.
• Because the physics and reconstruction of these muons are different from those of their lower-momentum counterparts, this paper presents for the first time dedicated studies of efficiencies, momentum assignment, resolution, scale, and showering of very high momentum muons produced at the LHC.
• These studies are performed using the 2016 and 2017 data sets of proton-proton collisions at $\sqrt{s} =$ 13 TeV with integrated luminosities of 36.3 and 42.1 fb$^{-1}$, respectively.
