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.
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).
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.
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.
