Definition: In particle physics, a boson is a type of particle that obeys the rules of Bose-Einstein statistics.omposite Bosons. 1  Mesons-Mesons are formed when two quarks bond together. 2  Since quarks are fermions and have half-integer spins, if two of them are bonded together, then the spin of the resulting particle (which is the sum of the individual spins) would be an integer, making it a boson.
