The spin of a boson is always an integer: 0, 1, 2, and so on . Examples are photons, gluons, gravitons, weak bosons, and the Higgs boson. Bosons can be piled on top of each other without limit.

Parastatistics – Notion in statistical mechanics.Bose gas – State of matter of many bosons.Anyon – Type of particle that occurs only in two-dimensional systems.As a consequence, when (for example) a gas of helium-4 atoms is cooled to temperatures very close to absolute zero and the kinetic energy of the particles becomes negligible, it condenses into a low-energy state and becomes a superfluid.Ĭertain quasiparticles are observed to behave as bosons and to follow Bose–Einstein statistics, including Cooper pairs, plasmons and phonons. One characteristic which becomes important in superfluidity and other applications of Bose–Einstein condensates is that there is no restriction on the number of bosons that may occupy the same quantum state. Īs quantum particles, the behaviour of multiple indistinguishable bosons at high densities is described by Bose–Einstein statistics. Stable nuclei of even mass number such as deuterium, helium-4 (the alpha particle), carbon-12 and lead-208.Since bosons have integer spin and fermions odd half-integer spin, any composite particle made up of an even number of fermions is a boson. See also: List of particles § Composite particlesĬomposite particles (such as hadrons, nuclei, and atoms) can be bosons or fermions depending on their constituents. ![]() Neutral weak boson – the force carrier that mediates the weak forceĬharged weak bosons (two types) – also force carriers that mediate the weak forceĪ tensor boson (spin=2) called the graviton (G) has been hypothesised as the force carrier for gravity, but so far all attempts to incorporate gravity into the Standard Model have failed. Gluons (eight different types) – force carriers that mediate the strong force Photon – the force carrier of the electromagnetic field
