- The Higgs mechanism is responsible for the generation of the gauge boson masses, and the fermion masses result from Yukawa-type interactions with the Higgs field.
- It arises in the case of a Yang–Mills theory with a gauge group G, coupled to a Higgs field which spontaneously breaks it down to a smaller group H via the Higgs mechanism.
- An example of mass gap arising for massless theories, already at the classical level, can be seen in spontaneous breaking of symmetry or Higgs mechanism.
- Every gauge field has an associated ghost, and where the gauge field acquires a mass via the Higgs mechanism, the associated ghost field acquires the same mass (in the Feynman–'t Hooft gauge only, not true for other gauges).
- A gauge transformed state is the same exact state, so that acting with a symmetry generator does not get one out of the vacuum (see Higgs mechanism).
- Historically, the Higgs mechanism of spontaneous symmetry breaking was a result of Yoichiro Nambu's application of superconductor theory to elementary particles, while the concept of renormalization came out of the study of second-order phase transitions in matter.
- They showed that if the symmetries of Yang–Mills theory were to be realized in the spontaneously broken mode, referred to as the Higgs mechanism, then Yang–Mills theory can be renormalized.
- It may involve work on supersymmetry, alternatives to the Higgs mechanism, extra spatial dimensions (such as the Randall–Sundrum models), Preon theory, combinations of these, or other ideas.
- The combination of the SU(2) gauge theory of the weak interaction, the electromagnetic interaction, and the Higgs mechanism is known as the Glashow–Weinberg–Salam model.
- Higgs wrote a second paper describing a theoretical model (now called the Higgs mechanism), but the paper was rejected (the editors of "Physics Letters" judged it "of no obvious relevance to physics").
- In 1967-8, Salam and Weinberg incorporated the Higgs mechanism into Glashow's discovery, giving it a modern form in electroweak theory, and thus theorised half of the Standard Model.
- It served as the prototype and significant ingredient of the Higgs mechanism underlying the electroweak symmetry breaking.
- In condensed matter physics a notable example is ferromagnetism; in particle physics the best known example is the Higgs mechanism in the Standard Model that breaks the electroweak symmetry.
- In fact, this analogy is an abelian example for the Higgs mechanism, which generates the masses of the electroweak [...] and [...] gauge particles in high-energy physics.
- During this period he developed what is now called Anderson localization (the idea that extended states can be localized by the presence of disorder in a system) and Anderson's theorem (concerning impurity scattering in superconductors); invented the Anderson Hamiltonian, which describes the site-wise interaction of electrons in a transition metal; proposed symmetry breaking within particle physics (this played a role in the development of the Standard Model and the development of the theory behind the Higgs mechanism, which in turn generates mass in some elementary particles); created the pseudospin approach to the BCS theory of superconductivity; made seminal studies of non-s-wave pairing (both symmetry-breaking and microscopic mechanism) in the superfluidity of He3, and helped found the area of spin-glasses.
