      abstract     = {A study of the polarisation and CP properties in $ZZ$
                      production is presented. The used data set corresponds to an
                      integrated luminosity of 140 fb$^{-1}$ of proton-proton
                      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. The
                      inclusive differential cross-section 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.},
