The Higgs boson (or BEH boson or ABEGHHK'tH boson) is an extremely unstable elementary particle with spin zero, no electric charge, and no color charge. The existence of the Higgs boson proves the existence of the Higgs field, which is a quantum field that exists throughout spacetime and breaks certain symmetry laws of the electroweak interaction. The Higgs boson is (as of 2020) the latest addition to the Standard Model of particle physics. Its experimental confirmation in 2012 won the 2013 physics Nobel prize for Peter Higgs and François Englert.

- At the heart of the Higgs physics programme is the question of how the Higgs boson couples to Standard Model elementary particles. Within the SM itself, all these couplings are uniquely determined. But new physics beyond the SM (BSM) can modify these couplings in many different ways.
- ... the famous particle bears the name of Peter Higgs alone. Over the years, all the prestigious prizes in physics have been awarded to different combinations of Brout, Englert, Higgs, Guralnik, Hagen and Kibble. ... Nambu's insight to apply the concept of spontaneous symmetry breaking to empty space was profound. In the strange quantum world, what we think of as empty space is anything but. Instead, it is a seething soup of particles constantly popping in and out of existence, and it is this structure in the vacuum itself that gives rise to particle masses. The thing that fills the vacuum is what has come to be known as the Higgs field. Some particles interact strongly with this field, others not at all, and it is the strength of the interaction with the HIggs field that determines the fundamental particles' masses.

- In regards to the mechanism, Brout and Englert make some comments, but give no quantitative argument. In the Higgs PRL paper, there is only the specific scalar electrodynamics example. In his physics letters paper Higgs observed that an argument given by Gilbert to negate the Goldstone theorem includes a term with a fixed vector such as can be found in radiation gauge electrodynamics. He makes no follow-up or extension of this argument in his PRL paper. The GHK paper does an extensive analysis of the mechanism and shows that in broken gauge theories in the radiation gauge that charge leaks out of any volume and consequently is not conserved since currents continue to exist in the limit of volumes tending toward infinity. This negates the basic assumption of a conserved charge that is required by the Goldstone theorem.

- ... string theory seems to require our world to have a property called supersymmetry. And a supersymmetric Standard Model with string theory boundary conditions has Higgs bosons and explains their properties. ... Finding a Higgs boson thus strongly supports the supersymmetric Standard Model, which in turn supports the notion that string theory is indeed the right approach to nature.
- Higgs, 84, shares the 8m Swedish kronor (£775,000) prize – and no shortage of kudos – with François Englert at the Free University of Brussels for showing how fundamental particles get their masses. Before the theory, the answer to this basic question was unknown. The Royal Swedish Academy awarded the prize for "the theoretical discovery of a mechanism that contributes to our understanding of the origin of mass of subatomic particles, and which recently was confirmed through the discovery of the predicted fundamental particle, by the Atlas and CMS experiments at Cern's Large Hadron Collider."

- ... one of the consequences of the electroweak symmetry is that, if nothing new is added to the theory, all elementary particles, including electrons and quarks, would be massless, which of course they are not. So, something has to be added to the electroweak theory, some new kind of matter or field, not yet observed in nature or in our laboratories. The search for the Higgs particle has been a search for the answer to the question: What is this new stuff we need?
