The ATLAS Collaboration has carried out the analysis of the inclusive four-lepton lineshape measurement using data corresponding to 20.3 fb−1 of integrated luminosity from proton-proton collisions at √s= 8 TeV at the LHC collected with the ATLAS detector. The study focuses on the differential cross section as a function of the 4-lepton mass spectrum ranging from 80 to 1000 GeV where several distinct physics processes give rise to the production of 4-lepton final state. These are the single Z resonant processes, the Higgs production at 125 GeV, as well as continuum ZZ production processes with qq¯ and gg initial states.
