Physics with four-leptons at the LHC

Several analyses with four-leptons in the final state performed by ATLAS and CMS experiments at the LHC are summarized. These results include Standard Model measurements on ZZ and Higgs boson production, as well as beyond Standard Model searches. The four-lepton signature of these processes leads to a very clean final state with low background. These features enhance the interest of these analyses, which may be performed in the context of beyond the Standard Model searches for the Run 2 period. In particular, the resonant pair production of new heavy scalars, the Madala boson, decaying to four W -bosons will be discussed. (paper)
