This performance is described in terms of reconstruction and isolation efficiencies and momentum resolutions for different classes of reconstructed muons. The results are obtained from an analysis of $J/\psi $ meson and $Z$ boson decays to dimuons, reconstructed from a data sample corresponding to an integrated luminosity of 40 pb$^{-1}$ . The measured performance is compared to Monte Carlo predictions and deviations from the predicted performance are discussed.engjournal article2019-02-04
