Abstract
The first observation of the electroweak (EW) production of a
Z
boson, a photon, and two forward jets (
Z
γ
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
γ
jj
is
σ

fb

. Single-differential cross sections in photon, leading lepton, and leading jet transverse momenta, and double-differential cross sections in
m
jj
and

Δ
η
jj
|
are also measured. Exclusion limits on anomalous quartic gauge couplings are derived at 95% confidence level in terms of the effective field theory operators
