As nouns the difference between boson and coboson

is that boson is a particle with totally symmetric composite quantum states, which exempts them from the Pauli exclusion principle, and that hence obeys 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 {{term|fermion|lang=en}} while coboson is any boson considered to be a composite particle.
