      abstract     = {A search for a narrow Z$'$ gauge boson with a mass between
                      5 and 70 GeV resulting from an $L_{\mu}-L_{\tau}$ $U(1)$
                      local gauge symmetry is reported. Events containing four
                      muons with an invariant mass near the standard model Z boson
                      mass are analyzed, and the selection is further optimized to
                      be sensitive to the events that may contain
                      Z$\to$Z$'\mu\mu\to4\mu$ decays. A data sample of
                      proton-proton collisions at a center-of-mass energy of 13
                      TeV is used, corresponding to an integrated luminosity of
                      77.3 fb$^{-1}$ recorded in 2016 and 2017 by the CMS detector
                      at the LHC. Theories that predict such a particle have been
                      proposed as an explanation of various experimental
                      discrepancies, including the lack of a dark matter signal in
                      direct-detection experiments, tension in the measurement of
                      the anomalous magnetic moment of the muon, and reports of
                      possible lepton flavor universality violation in B meson
                      decays. The event yields are consistent with the standard
                      model predictions. Upper limits of 10$^{-8}$-10$^{-7}$ at
                      95\% confidence level are set on the product of branching
                      fractions $\mathcal{B}$(Z $\to$ Z$' \mu \mu$)
                      $\mathcal{B}$(Z$' \to\mu \mu$), depending on the Z$'$ mass,
                      which excludes a Z$'$ boson coupling strength to muons above
                      0.004-0.3. These are the first dedicated limits on
                      $L_{\mu}-L_{\tau}$ models at the LHC and result in a
                      significant increase in the excluded model parameter space.},
