      abstract     = {A search for flavor violating decays of the Z boson to
                      charged leptons is performed using data from proton-proton
                      collisions at $\sqrt{s}$ = 13 TeV collected with the CMS
                      detector at the LHC, corresponding to an integrated
                      luminosity of 138 fb$^{-1}$. Each of the decays Z $\to$
                      e$μ$, Z $\to$ e$τ$, and Z $\to$$μτ$ is considered. The
                      data are consistent with the backgrounds expected from
                      standard model processes. For the Z $\to$ e$μ$ channel the
                      observed (expected) 95\% confidence level upper limit on the
                      branching fraction is 1.9 (2.0) $\times$ 10$^{-7}$, which is
                      the most stringent direct limit to date on this process; the
                      corresponding limits for the Z $\to$ e$τ$ and Z $\to$
                      $μτ$ channels are 13.8 (11.4) $\times$ 10$^{-6}$ and 12.0
                      (5.3) $\times$ 10$^{-6}$, respectively. Additionally, the
                      e$μ$ final state is used to search for lepton flavor
                      violating decays of Z' resonances in the mass range from 110
                      to 500 GeV. No significant excess is observed above the
                      predicted background levels.},
