Decays of a 125 GeV Standard-Model Higgs boson. Teh pie chart shows that 57% of the decay products are bottom or anti-bottom quarks; 21% W plus and W minus bosons; 9% gluons; 6%tau/anti-tau; 3%charm/anti-charm quarks; 3%ZZ; and 1%others

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.
