Fermions

n. any particle (such as electron, proton or neutron) that complies to the Fermi-Dirac statistics and is subject to the Pauli exclusion principle (Physics)

In particle physics, fermions are particles with half-integer spin, such as protons and electrons. They are named after Enrico Fermi. In the Standard Model there are two types of elementary fermions: quarks and leptons. The 24 fundamental fermionic flavours are:12 quarks - 6 particles (u · d · s · c · b · t) with 6 corresponding antiparticles;12 leptons - 6 particles (e ·  μ · τ  ·   ν_e · ν_μ · ν_τ) with 6 corresponding antiparticles, of which 3 are neutrinos and 3 are antineutrinos.

Particles which obey Pauli's exclusion principle , for example, protons , neutrons and electrons . They all have half integer intrinsic angular momentum (spin ). See also boson .
