noun

Fermión

(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; (slightly more loosely) any such particle or any composite particle composed of fermions.

Examples :

"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."

Según el teorema de la estadística de espín, la función de onda de un sistema de fermiones idénticos (partículas de espín semientero) es antisimétrica bajo la operación de intercambio de dos partículas cualesquiera.
