The Higgs boson decays into:
-
2 x Z bosons , which in turn decay to two pairs of charged leptons,
-
2 x photons
-
2 x W bosons , which in turn decay to 2 charged leptons and 2 neutrinos.
-
tau lepton pairs.
See the pie chart, right, summarising how often a 125 GeV Higgs boson decays into known particles.
