In particle physics, a gauge boson is a bosonic elementary particle that acts as the force carrier for elementary fermions. [ 1 ] [ 2 ] Elementary particles whose interactions are described by a gauge theory interact with each other by the exchange of gauge bosons, usually as virtual particles .
A scalar boson is a boson whose spin equals zero. [1] A boson is a particle whose wave function is symmetric under particle exchange and therefore follows Bose–Einstein statistics. The spin–statistics theorem implies that all bosons have an integer-valued spin. [2] Scalar bosons are the subset of bosons with zero-valued spin.
Standard Model of Particle Physics. The diagram shows the elementary particles of the Standard Model (the Higgs boson, the three generations of quarks and leptons, and the gauge bosons), including their names, masses, spins, charges, chiralities, and interactions with the strong, weak and electromagnetic forces.
Quantum electrodynamics is an abelian gauge theory with the symmetry group U(1) and has one gauge field, the electromagnetic four-potential, with the photon being the gauge boson. The Standard Model is a non-abelian gauge theory with the symmetry group U(1) × SU(2) × SU(3) and has a total of twelve gauge bosons: the photon , three weak bosons ...
Feynman diagram of the fusion of two electroweak vector bosons to the scalar Higgs boson, which is a prominent process of the generation of Higgs bosons at particle accelerators (q: quark particle, W and Z: vector bosons of the electroweak interaction, H 0: Higgs boson) The W and Z particles interact with the Higgs boson as shown in the Feynman ...
Frank Close comments that 1960s gauge theorists were focused on the problem of massless vector bosons, and the implied existence of a massive scalar boson was not seen as important; only Higgs directly addressed it. [38]: 154, 166, 175 ) In the paper by GHK the boson is massless and decoupled from the massive states. [4]
Double-gluon glueballs can have total angular momentum J = 0 (which are either scalar or pseudo-scalar) or J = 2 . Triple-gluon glueballs can have total angular momentum J = 1 (vector boson) or 3 (third-order tensor boson). All glueballs have integer total angular momentum that implies that they are bosons rather than fermions.
The same can happen in other gauge theories. In the broken phase the fluctuations of the scalar field will manifest themselves as a naturally light Higgs boson, as a matter of fact even too light to explain the electroweak symmetry breaking in the minimal model - much lighter than vector bosons. There are non-minimal models that give a more ...
