n. Any of a class of particles, such as the photon, pion, or alpha particle, that have zero or integral spin and obey statistical rules permitting any number of identical particles to occupy the same quantum state.

n. A particle with totally symmetric composite quantum states, which exempts them from the Pauli exclusion principle, and that obey Bose-Einstein statistics. They have integer spin. Among them are many elementary particles, and some (gauge bosons) are known to carry the fundamental forces. Compare fermion.

n. A boatswain.

n. A fundamental particle that obeys Bose-Einstein statistical rules, but not the Pauli exclusion principle; the spin value of a boson is always an integer. Examples of bosons are alpha particles, photons, and those nuclei which have an even mass number.

n. See boatswain.

n. A corruption of boatswain, representing its common pronunciation.

n. A bolt for the crossbow, having a round knob at the end, with a small point projecting from it.

n. any particle that obeys Bose-Einstein statistics but not the Pauli exclusion principle; all nuclei with an even mass number are bosons

"I am on the record saying that the existence of the Higgs boson is yet to be confirmed experimentally."
