Subatomic particle with integral spin that is governed by Bose-Einstein statistics. 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.
