| Abstract: A measurement of the $ Z\gamma $ production cross section in proton-proton collisions at a center-of-mass energy of 13.6 TeV using the leptonic final states is presented. A data set corresponding to an integrated luminosity of 34.8 fb$ ^{-1} $, collected by the CMS experiment at the LHC in 2022 is used. Events with an oppositely charged pair of muons or electrons together with an isolated photon are selected. The measured fiducial cross section for the combined muon and electron channels is 1.896 $ \pm $ 0.006 (th) $\pm$ 0.054 (syst) $\pm$ 0.033 (stat) pb. | ||
