What is Gauge boson?
[[File:Standard Model of Elementary Particles.svg|thumb|300px|The [[Standard Model]] of elementary particles Gauge bosons are in the fourth column in red]] '''Gauge bosons''' are carrier particles for three of the four [[fundamental forces]]. In the [[Standard Model]] of [[particle physics]], there are four kinds of gauge bosons. The three gauge bosons are as follows: # [[W and Z bosons]], which carry the [[weak force]] # [[Gluon]]s, which carry the [[strong force]] # [[Photon]]s, which carry the [[Electromagnetism|electromagnetic force]] The only remaining fundamental force that has no known gauge boson is [[gravity]]. The [[Theoretical Particle|theoretical]] gauge boson for gravity is called a [[graviton]]. All gauge bosons are [[boson]]s, which simply means that two or more of them can exist in the same place at the same time, unlike [[fermion]]s. It also means that gauge bosons have a [[spin (physics)|spin]] of 0, 1, or 2. Gauge bosons are thought to interact with the [[Higgs field]]. This theoretical field is believed by many scientists to be responsible for why some gauge bosons – like W and Z bosons – have [[mass]], while others – such as photons – do not have mass. {{elementary}} [[Category:Elementary particles]]
