In particle physics, a fermion is a subatomic particle that follows Fermi–Dirac statistics. Fermions have a half-integer spin (spin ⁠ 1 / 2 ⁠, spin ⁠ 3 / 2 ⁠, etc.) and obey the Pauli exclusion principle.

2025年2月21日 · Fermion, any member of a group of subatomic particles having odd half-integral angular momentum (spin 12, 32), named for the Fermi-Dirac statistics that describe its behaviour. Fermions include particles in the class of leptons (e.g., electrons, muons), baryons (e.g., neutrons, protons, lambda

2018年4月2日 · In particle physics, a fermion is a type of particle that obeys the rules of Fermi-Dirac statistics, namely the Pauli Exclusion Principle. These fermions also have a quantum spin with contains a half-integer value, such as 1/2, -1/2, -3/2, and so on.

Boson and Fermion Facts A class of bosons known as gauge bosons act as “force carriers” between particles. These include the photon (which carries the electromagnetic force), gluon (which carries the strong nuclear force), and W and Z …

A fermion is a category of elementary particles. They are very small and very light. Fermions can be thought of as the building blocks of matter because atoms are made up of fermions. Paul Dirac named them fermions in honor of the famous scientist Enrico Fermi.

2024年10月1日 · Boson and Fermion Facts. A class of bosons known as gauge bosons act as “force carriers” between particles. These include the photon (which carries the electromagnetic force), gluon (which carries the strong nuclear force), and W and Z bosons (which carry the weak nuclear force). The hypothetical graviton, which carries gravity, has not ...

A composite particle containing an odd number of elementary fermions is a fermion. Examples: A baryon contains three quarks and is therefore a fermion. The nucleus of a carbon-13 atom contains six protons and seven neutrons and is therefore a fermion.

Two-Particle Wave Functions. We learned in quantum mechanics that a particle is represented by a wave, \(\Psi(\mathrm{x}, \mathrm{y}, \mathrm{z}, \mathrm{t})\), the absolute square of which gives the relative probability of finding the particle at some point in spacetime.

Fermion : An odd half-integer spin particle. Fermions act on each other by exchanging bosons. Examples include leptons (such as the electron), neutrons, protons and quarks. They are indistinguishable, have antisymmetric wave functions, and obey Fermi-Dirac statistics.
