boson: see elementary particles elementary particles, the most basic physical constituents of the universe.
Basic Constituents of Matter
Molecules are built up from the atom, which is the basic unit of any chemical element. .....

Bosons have integral values of the quantum mechanical property called spin and are "gregarious" in the sense .....

Bosons include mesons, nuclei of even mass number, and the particles required to embody the fields of quantum field theory. Unlike fermions, there is no limit to the number of bosons that can occupy the same quantum state, a behaviour that gives rise to the superfluidity of helium-4. boson [′bō‚sän] (statistical mechanics) A particle that obeys Bose-Einstein statistics; includes photons, pi mesons, and all nuclei having an even number of particles and all particles with integer spin. Boson bose particle, a particle with zero or integral spin. Bosons obey Bose-Einstein statistics (hence the designation of the particle). Bosons include light quanta, or photons (spin 1); quanta of the gravitational field (if such exist), or gravi-tons (spin 2); unstable elementary particles such as mesons and boson resonances; and also compound particles made up of an even number of fermions (particles of half-integral spin)—for example, atomic nuclei with an even total number of protons and neutrons (a deuteron, a 4He nucleus or alpha particle, and so on); and gas molecules. Bosons are also quasi-particles of integral (or zero) spin—for example, pho-nons in the solid state and in liquid 4He and excitons in semiconductors and dielectrics. V. P.
