any particle that obeys Fermi-Dirac statistcs and is subject to the Pauli exclusion principle.

a particle with half-integer spin (e.g. electrons, protons, neutrons). Fermions obey the Pauli exclusion principle. The wave function describing a collection of fermions is antisymmetric with respect to the exchange of identical particles.

The term for a particle with half-integer spin. Examples include the quarks and leptons of the Standard Model.

a particle, or patter of string vibration, with half a whole odd number amount of spin; typically a matter particle.

Fermions are particles with half integral Gluon The strong interaction between quarks is visualised as an exchange of massless electrically neutral particles called gluons (so called because they glue the quarks together).

A particle with a spin of an odd half integer number (1/2, 3/2, 5/2...). Fundamental fermions are the building blocks of matter.

A particle with half integral units of the basic unit of spin, .

General name for a particle that is a matter constituent, characterized by spin in odd half integer quantum units (1/2,3/2,5/2...). Named for Italian physicist Enrico Fermi. Quarks, leptons and baryons are all fermions.

Particle with half- integer spin, and therefore exhibiting wavefunction antisymmetry and Fermi statistics.

a particle such as the electron with a half-integral spin

A type of particle with "odd half-integral angular momentum"â€”a spin of 1/2, 3/2, etc. Spin refers to an intrinsic quality of all particles. Examples of fermions are electrons, neutrons, and protons. The other type of particle is the boson.

Any particle that has odd-half-integer (1/2, 3/2, ...) intrinsic angular momentum (spin), measured in units of h-bar. As a consequence of this peculiar angular momentum, fermions obey a rule called the Pauli Exclusion Principle, which states that no two fermions can exist in the same state at the same time. Many of the properties of ordinary matter arise because of this rule. Electrons, protons, and neutrons are all fermions, as are all the fundamental matter particles, both quarks and leptons.

A particle having a spin that is an odd integer multiple of (h-bar)

In particle physics, fermions are particles with half-integer spin. They are named after Enrico Fermi. In the Standard Model there are two types of elementary fermions: quarks and leptons.
