are hypothetical elementary particles
predicted by the Standard Model
of particle physics
. These bosons
play a rather fundamental role: they are the carrier particles
of the Higgs field
which is thought to permeate the universe and to give mass
to all particles. They have not yet been observed.
The Higgs boson, sometimes called the God particle, was first predicted in the 1960s by the Scottish physicist Peter Higgs[?].
The Higgs boson itself has mass. Theory gives an upper limit for this mass of about 200 GeV. As of 2002, particle accelerators have probed energies up to 115 GeV. While a small number of events have been recorded that could be interpreted as resulting from Higgs bosons, the evidence so far is inconclusive. It is expected that the Large Hadron Collider[?], currently under construction at CERN, will be able to confirm the existence of Higgs bosons.
Since the Higgs field is a scalar field, the Higgs boson has spin zero.
