In particle physics, a fermion is a particle that follows FermiDirac statistics and generally has half odd integer spin 1/2, 3/2 etc. Wikipedia
Quantum system whose wave function changes when exchanging identical instances Wikidata
A particle which obeys Fermi–Dirac statistics. OmegaWiki
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; (slightly more loosely) any such particle or any composite particle composed of fermions. Wiktionary
Particle with totally antisymmetric composite quantum states. Wiktionary (translation)
EN
The fermions treated by the Standard Model are the (composite) baryons and the (elementary) leptons and quarks. Wiktionary
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. Wiktionary
