| Abstract: The measurement of the production cross section of a Z boson and a photon in the final state with one photon and large missing transverse momentum, and a search for the presence of neutral anomalous triple gauge couplings are presented. The results are based on data collected by the CMS experiment in proton-proton collisions at $ \sqrt{s}= $ 13 TeV during the 2016, 2017, and 2018 LHC running periods, corresponding to an integrated luminosity of 138 fb$ ^{-1} $. The measured cross section is compatible with the theoretical predictions at the next-to-next-to-leading order in QCD. The study of the photon transverse momentum spectrum yields the most stringent limits on the anomalous triple gauge couplings provided by the CMS experiment to date. | ||
