Abstract
Measurements of four-lepton (, ) production cross sections at the resonance in collisions at the LHC with the ATLAS detector are presented. For dilepton and four-lepton invariant mass regions and , the measured cross sections are and at and 8 TeV, respectively. By subtracting the nonresonant production contributions and normalizing with events, the branching fraction for the boson decay to is determined to be , consistent with the standard model prediction.
