Any subatomic particle, like any particle in the [[three-dimensional space]] that obeys the [[Scientific law|laws]] of [[quantum mechanics]], can be either a boson (with integer [[Spin (physics)|spin]]) or a fermion (with odd half-integer spin).

In the Standard Model, all the elementary fermions have spin 1/2, and are divided into the quarks which carry [[color charge]] and therefore feel the strong interaction, and the [[leptons]] which do not. The elementary bosons comprise the gauge bosons (photon, W and Z, gluons) with spin 1, while the Higgs boson is the only elementary particle with spin zero.

The hypothetical graviton is required theoretically to have spin 2, but is not part of the Standard Model. Some extensions such as [[supersymmetry]] predict additional elementary particles with spin 3/2, but none have been discovered as of 2023.

Due to the laws for spin of composite particles, the baryons (3 quarks) have spin either 1/2 or 3/2 and are therefore fermions; the mesons (2 quarks) have integer spin of either 0 or 1 and are therefore bosons.
