Search for heavy resonances decaying into a pair of Z bosons in the ℓ+ℓ-ℓ′ +ℓ′ - and ℓ+ℓ-νν¯ final states using 139 fb - 1 of proton–proton collisions at √s=13 TeV with the ATLAS detector

A search for heavy resonances decaying into a pair of Z bosons leading to l+l-l +l - and l+l-nu nu <overbar></mml:mover> final states, where l stands for either an electron or a muon, is presented. The search uses proton-proton collision data at a centre-
