N2 - A search for heavy resonances decaying into apair of Z bosons leading to ℓ+ℓ−ℓ+ℓ− and ℓ+ℓ−νν¯ finalstates, where stands for either an electron or a muon, ispresented. The search uses proton–proton collision data at acentre-of-mass energy of 13 TeV corresponding to an integratedluminosity of 36.1 fb−1 collected with the ATLASdetector during 2015 and 2016 at the Large Hadron Collider.Different mass ranges for the hypothetical resonances areconsidered, depending on the final state and model. The differentranges span between 200 and 2000 GeV. The resultsare interpreted as upper limits on the production cross sectionof a spin-0 or spin-2 resonance. The upper limits forthe spin-0 resonance are translated to exclusion contours inthe context of Type-I and Type-II two-Higgs-doublet models,while those for the spin-2 resonance are used to constrainthe Randall–Sundrum model with an extra dimension givingrise to spin-2 graviton excitations.
