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 …

One of the main tasks of the CMS experiment is to search for new phenomena in proton-
proton (pp) collisions delivered by the CERN LHC. Good identification and precise
measurement of muons, electrons, photons, and jets over a large energy range and at high
instantaneous luminosities are necessary for these searches to be effective. In particular,
searches for heavy gauge bosons such as the Z [1, 2] and W [3] rely on precise
reconstruction of muons up to very high momentum. With the data recorded from pp …
