The Higgs boson is predicted to decay into several different final states or decay channels. For the discovery of July 4, ATLAS combined the most sensitive channels, of two photons and of four leptons, yielding a signal above the 5-sigma threshold. This Higgs candidate event shows four muons from a possible parent particle of mass 124.6 GeV. Such an event would be expected for a Higgs boson decaying to two Z bosons, in which each Z decays into a pair of muons.
