      abstract     = {A search for charged-lepton flavour violation (CLFV) in top
                      quark (t) production and decay is presented. The search uses
                      proton-proton collision data corresponding to 138
                      fb$^{−1}$ collected with the CMS experiment at
                      $\sqrt{s}={13}$ TeV. The signal consists of the production
                      of a single top quark via a CLFV interaction or top quark
                      pair production followed by a CLFV decay. The analysis
                      selects events containing a hadronically decaying τ lepton
                      and a muon of opposite electric charge, as well as at least
                      three jets, one of which is identified as originating from
                      the fragmentation of a bottom quark. Machine learning
                      classification techniques are used to distinguish signal
                      from standard model background events. The results of this
                      search are consistent with the standard model expectations.
                      The upper limits at 95\% confidence level on the branching
                      fraction $\mathcal{B}$ for CLFV top quark decays to a muon,
                      a τ lepton, and an up or a charm quark are set at
                      $\mathcal{B}\left({\text{t}}\to \mu \tau {\text{u}}\right)$
                      < (0.04, 0.08, and 0.12) × 10$^{−6}$, and
                      $\mathcal{B}\left({\text{t}}\to \mu \tau {\text{c}}\right)$
                      < (0.81, 1.71, and 2.05) × 10$^{−6}$ for scalar, vector,
                      and tensor-like operators, respectively.[graphic not
