Search for new particles decaying to ZZ using final states with leptons and jets with the ATLAS detector in √s = 7 TeV proton–proton collisions

A search is presented for a narrow resonance decaying to a pair of Z bosons using data corresponding to 1.02 fb<sup>−1</sup> of integrated luminosity collected by the ATLAS experiment from pp collisions at √s = 7 TeV. Events containing either four charged leptons (ℓℓℓℓ) or two charged le...
