Description: |
  This Letter presents the measurement of the fiducial and differential cross-sections of the electroweak production of a
  $Z\gamma$ pair in association with two jets. The analysis uses 140 fb${}^{-1}$ of LHC proton-proton collision data taken
  at $\sqrt{s}=13$ TeV recorded by the ATLAS detector during the years 2015-2018. Events with a $Z$ boson candidate decaying
  into either an $e^+e^-$ or $\mu^+\mu^-$ pair, a photon and two jets are selected. The electroweak component is extracted by
  requiring a large dijet invariant mass and a large rapidity gap between the two jets and is measured with an observed and
  expected significance well above five standard deviations. The fiducial $pp \to Z\gamma jj$ cross-section for the electroweak
  production is measured to be $3.6 \pm 0.5$ fb. The total fiducial cross-section that also includes contributions where the jets
  arise from strong interactions is measured to be $16.8+2.0-1.8$ fb. The results are consistent with the Standard Model predictions.
  Differential cross-sections are also measured using the same events and are compared with partoni-shower Monte Carlo simulations.
  Good agreement is observed between data and predictions.
