Cross-sections for the production of a $Z$ boson in association with two photons are measured in proton-proton collisions at a centre-of-mass energy of $13 \\, \\mathrm{TeV}$. The data used correspond to an integrated luminosity of $139 \\, \\mathrm{fb}^{-1}$ recorded by the ATLAS experiment during Run 2 of the LHC. The measurements use the electron and muon decay channels of the $Z$ boson, and a fiducial phase-space region where the photons are not radiated from the leptons. The integrated $Z(\\rightarrow\\ell\\ell)\\gamma\\gamma$ cross-section is measured with a precision of $12\\%$ and differential cross-sections are measured as a function of six kinematic variables of the $Z\\gamma\\gamma$ system. The data are compared with predictions from MC event generators which are accurate to up to next-to-leading order in QCD. The cross-section measurements are used to set limits on the coupling strengths of dimension-8 operators in the framework of an effective field theory.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.132903.v1/t1","@type":"Dataset","description":"Measured fiducial-level integrated cross-section.
