      abstract     = {A search for the production of a top quark in association
                      with a photon and additional jets via flavor changing
                      neutral current interactions is presented. The analysis uses
                      proton-proton collision data recorded by the CMS detector at
                      a center-of-mass energy of 13 TeV, corresponding to an
                      integrated luminosity of 138 fb$^{-1}$. The search is
                      performed by looking for processes where a single top quark
                      is produced in association with a photon, or a pair of top
                      quarks where one of the top quarks decays into a photon and
                      an up or charm quark. Events with an electron or a muon, a
                      photon, one or more jets, and missing transverse momentum
                      are selected. Multivariate analysis techniques are used to
                      discriminate signal and standard model background processes.
                      No significant deviation is observed over the predicted
                      background. Observed (expected) upper limits are set on the
                      branching fractions of top quark decays:
                      $\mathcal{B}$(t$\to$u$\gamma$) $\lt$ 0.95$\times$10$^{-5}$
                      (1.20$\times$10$^{-5}$) and $\mathcal{B}$(t$\to$c$\gamma$)
                      $\lt$ 1.51$\times$10$^{-5}$ (1.54$\times$10$^{-5}$) at 95\%
                      confidence level, assuming a single nonzero coupling at a
                      time. The obtained limit for $\mathcal{B}$(t$\to$u$\gamma$)
                      is similar to the current best limit, while the limit for
                      $\mathcal{B}$(t$\to$c$\gamma$) is significantly tighter than
                      previous results.},
