fermion

/ˈfɜːmɪɒn/

fermion noun: 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;.

Noun

fermion (plural fermions)

  1. (particle, Standard Model) 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;
    • The fermions treated by the Standard Model are the (composite) baryons and the (elementary) leptons and quarks.
    • According to the spin–statistics theorem, the wavefunction of a system of identical fermions (particles of half-integer spin) is antisymmetric under the operation of swapping any two particles.
  2. (particle, Standard Model, slightly more loosely) any such particle or any composite particle composed of fermions.
