or Higgs boson
Carrier of an all-pervading fundamental field (Higgs field) that is hypothesized as a means of endowing mass on some elementary particles through its interactions with them. It was named for Peter W. Higgs
born 1929
of the University of Edinburgh, one of those who first postulated the idea.
The Higgs mechanism explains why the carriers of the weak force are heavy, while the carrier of the electromagnetic force has a mass of zero. There is no direct experimental evidence for the existence of either the Higgs particle or the Higgs field.
