  "abstract": "The first observation of the electroweak (EW) production of a Z boson, a photon, and two forward jets (Z$\\gamma$jj) in proton-proton collisions at a center-of-mass energy of 13 TeV is presented. A data set corresponding to an integrated luminosity of 137 fb$^{-1}$, collected by the CMS experiment at the LHC in 2016-2018 is used. The measured fiducial cross section for EW Z$\\gamma$jj is $\\sigma_{\\mathrm{EW}}=$ 5.21$\\pm$0.52 (stat) $\\pm$0.56 (syst) fb = 5.21$\\pm$0.76 fb. Single-differential cross sections in photon, leading lepton, and leading jet transverse momenta, and double-differential cross sections in $m_{\\mathrm{jj}}$ and $\\lvert\\Delta\\eta_{\\mathrm{jj}}\\rvert$ are also measured. Exclusion limits on anomalous quartic gauge couplings are derived at 95% confidence level in terms of the effective field theory operators $\\mathrm{M}_{0}$ to $\\mathrm{M}_{5}$, $\\mathrm{M}_{7}$, $\\mathrm{T}_{0}$ to $\\mathrm{T}_{2}$, and $\\mathrm{T}_{5}$ to $\\mathrm{T}_{9}$.",
