The electroweak production of Z(νν‾)γZ(νν)γ in association with two jets is studied in a regime with a photon of high transverse momentum above 150 GeV using proton–proton collisions at a centre-of-mass energy of 13 TeV at the Large Hadron Collider. The analysis uses a data sample with an integrated luminosity of 139 fb−1−1 collected by the ATLAS detector during the 2015–2018 LHC data-taking period. This process is an important probe of the electroweak symmetry breaking mechanism in the Standard Model and is sensitive to quartic gauge boson couplings via vector-boson scattering. The fiducial Z(νν‾)γjjZ(νν)γjj cross section for electroweak production is measured to be 0.77−0.30+0.340.77−0.30+0.34​ fb and is consistent with the Standard Model prediction.
