fermion

noun

Any of a class of particles having a spin that is half an odd integer and obeying the exclusion principle, by which no more than one identical particle may occupy the same quantum state. The fermions include the baryons, quarks, and leptons.

An elementary or composite particle, such as an electron, quark, or proton, whose spin is an integer multiple of 1/2. Fermions act on each other by exchanging bosons and are subject to the Pauli exclusion principle, which requires that no two fermions be in the same quantum state. Fermions are named after the physicist Enrico Fermi, who along with Paul Dirac developed quantum statistical models of their behavior.

Compare boson

Noun

(plural fermions)

  1. A particle with totally antisymmetric composite quantum states, which means it must obey the Pauli exclusion principle and hence Fermi–Dirac statistics. They have half-integer spin. Among them are many elementary particles, most derived from quarks. Compare boson.
Origin

From Enrico Fermi (Italian-American physicist) + -on.
