CERN Says the Higgs Boson Did Something Unexpected - Futurism

Typically, they’ve seen it decay into comparatively-heavy particles, but muons are far lighter and interact less with the field given off by the Higgs boson.

“[Our CERN team] is proud to have achieved this sensitivity to the decay of Higgs bosons to muons, and to show the first experimental evidence for this process,” CERN spokesperson Roberto Carlin said in a press release.

Muons are second-generation particles.
