Measurements of Four-Lepton Production at the Z Resonance in pp Collisions at sqrt[s]=7 and 8 TeV with ATLAS.
Measurements of four-lepton (4ℓ, ℓ=e,μ) production cross sections at the Z resonance in pp collisions at the LHC with the ATLAS detector are presented. For dilepton and four-lepton invariant mass regions m_{ℓ^{+}ℓ^{-}}>5 GeV and 80
