In particle physics, a vector boson is a boson whose spin equals one. Vector bosons that are also elementary particles are gauge bosons, the force carriers of fundamental interactions. Some composite particles are vector bosons, for instance any vector meson (quark and antiquark).

In particle physics, the W and Z bosons are vector bosons that are together known as the weak bosons or more generally as the intermediate vector bosons. These elementary particles mediate the weak interaction; the respective symbols are.

Intermediate vector boson, type of boson associated with the electromagnetic and weak forces in unified form. See W

2024年3月10日 · The Feynman diagram for beta decay of a neutron into a proton, electron, and electron antineutrino via an intermediate $W^−$ boson. This modern theory of weak interaction is in contrast to the older (and now obsolete) Fermi's theory which tried to model the weak nuclear force without any intermediate particles.

We are used to thinking of the weak force only in its lowest energy manifestation of "radioactive" nuclear decay, or element building in stars, reactions mediated by the "W" family of Intermediate Vector Bosons (IVBs) of the electroweak (EW) unified-force level.

A Unitary Argument for the Vector Boson Theory (II) This argument told physicists that four point theory would fail at high energies and argued for the intermediate boson theory

Intermediate Vector Bosons. The W and Z particles are the massive exchange particles which are involved in the nuclear weak interaction, the weak force between electrons and neutrinos. They were predicted by Weinberg, Salam, and Glashow in 1979 and measured at CERN in 1982.

Weak force transformations recreate primordial "symmetric energy states" of the "Big Bang" force-unification eras (in the case of the "W" IVB (Intermediate Vector Boson), the electroweak force unification era) to accomplish the invariant creation and transformation of …

In electromagnetic and weak interactions the exchanged parti cle is a member of the family called the vector bosons. This term refers to a clas sification of particles according to one of their most basic properties: spin an gular momentum.

Weak interactions are carried out by three intermediate vector bosons: W+ and W-(mass 80.4 GeV), and Z0 (91.2 GeV) Since these bosons are very massive particles, weak interactions have very short range (order of 2 ×10-3 fm) Historically, all observed weak processes were charged current reactions mediated by W+ or W-bosons (like -decay ...
