The four vector bosons (spin=1) that are the gauge bosons for the Standard Model: γ Photon g Gluons (eight different types) Z Neutral weak boson W ± Charged weak bosons (two types) There may be a sixth tensor boson (spin=2), the graviton (G), that would be the force-carrier for gravity.

Keka 1 1 25. A boson is a particle which carries a force.It has a whole number spin (spin is a property of subatomic particles).Bosons carry energy. A photon is an example of a boson as it has a spin of 1 and carries electromagnetism. Mesons are also bosons as they carry nuclear force. Bosons are different from fermions, which are particles that make up matter, because bosons obey Bose.
