Any elementary or composite particle that has half-integer spin and thus obeys Fermi–Dirac statistics and the Pauli exclusion principle (equivalently, a particle for which the wavefunction of any system of identical such particles changes sign whenever two are swapped); a baryon, a lepton or a quark; particle
    — The fermions treated by the Standard Model are the (composite) baryons and the (elementary) leptons and quarks.
