noun

フェルミオン

(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."

スピン統計の定理によれば、同一のフェルミオン（半整数スピンの粒子）の系の波動関数は、任意の2つの粒子を交換する操作に対して反対称である。
