The used data set corresponds to an integrated luminosity of $140$ fb$^{-1}$ of proton\u2013proton collisions at a centre-of-mass energy of $13$ TeV recorded by the ATLAS detector at the Large Hadron Collider. The $ZZ$ candidate events are reconstructed using two same-flavour opposite-charge electron or muon pairs. The production of two longitudinally polarised $Z$ bosons is measured with a significance of $4.3$ standard deviations, and its cross-section is measured in a fiducial phase space to be $2.45 \\pm 0.60$ fb, consistent with the next-to-leading order Standard Model prediction of $2.10 \\pm 0.09$ fb. The differential cross-section of the inclusive $ZZ$ production as a function of a CP-sensitive angular observable is also measured. The results are used to constrain anomalous CP-odd neutral triple gauge couplings.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.143611.v1/t1","@type":"Dataset","description":"Unfolded differential cross-section as a function of the Optimal Observable $\\mathcal{O}_{T_{yz,1} T_{yz,3}}$","name":"Table 1"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins2709671?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/143611"}],"inLanguage":"en","name":"Evidence of pair production of longitudinally polarised vector bosons and study of CP properties in $ZZ \\to 4\\ell$ events with the ATLAS detector at $\\sqrt{s} = 13$ TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins2709671?version=1","version":1}
