The Inclusive four-lepton lineshape measurement from pp collisions at 8 TeV with ATLAS

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 $\sqrt{s}= 8$ 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 $q\bar{q}$ and $gg$ initial states.
