Název v původním jazyce

Muon reconstruction and identification efficiency in ATLAS using the full Run 2 pp collision data set at <mml:msqrt>s</mml:msqrt>=13 TeV

Popis výsledku v původním jazyce

This article documents the muon reconstruction and identification efficiency obtained by the ATLAS experiment for 139 fb-1 of pp collision data at &lt;mml:msqrt&gt;s&lt;/mml:msqrt&gt;=13 TeV collected between 2015 and 2018 during Run 2 of the LHC. The increased instantaneous luminosity delivered by the LHC over this period required a reoptimisation of the criteria for the identification of prompt muons. Improved and newly developed algorithms were deployed to preserve high muon identification efficiency with a low misidentification rate and good momentum resolution. The availability of large samples of Z -&gt; mu mu and J/psi -&gt; mu mu decays, and the minimisation of systematic uncertainties, allows the efficiencies of criteria for muon identification, primary vertex association, and isolation to be measured with an accuracy at the per-mille level in the bulk of the phase space, and up to the percent level in complex kinematic configurations. Excellent performance is achieved over a range of transverse momenta from 3 GeV to several hundred GeV, and across the full muon detector acceptance of |eta|&lt;2.7.
