      abstract     = {This Letter presents the first study of the energy
                      dependence of diboson polarization fractions in
                      $WZ→ℓνℓ′ℓ′(ℓ,ℓ′=e,μ)$ production. The
                      dataset used corresponds to an integrated luminosity of 140
                      fb$^{-1}$ of proton-proton collisions at a center-of-mass
                      energy of 13 TeV recorded by the ATLAS detector. Two
                      fiducial regions with an enhanced presence of events
                      featuring two longitudinally polarized bosons are defined. A
                      nonzero fraction of events with two longitudinally polarized
                      bosons is measured with an observed significance of 5.3
                      standard deviations in the region with 100<$p_T^Z$≤200 GeV
                      and 1.6 standard deviations in the region with $p_T^Z$>200
                      GeV, where $p_T^Z$ is the transverse momentum of the Z
                      boson. This Letter also reports the first study of the
                      radiation-amplitude-zero effect. Events with two
                      transversely polarized bosons are analyzed for the
                      $ΔY(ℓWZ)$ and $ΔY(WZ)$ distributions defined
                      respectively as the rapidity difference between the lepton
                      from the W boson decay and the Z boson and the rapidity
                      difference between the W boson and the Z boson. Significant
                      suppression of events near zero is observed in both
                      distributions. Unfolded $ΔY(ℓWZ)$ and $ΔY(WZ)$
                      distributions are also measured and compared to theoretical
                      predictions.},
