In particle physics, a fermion is a particle that follows Fermi–Dirac statistics. Generally, it has a half-odd-integer spin: spin 1/2, spin 3/2, etc. In addition, these particles obey the Pauli exclusion principle. Fermions include all quarks and leptons and all composite particles made of an odd number of these, such … See more The Standard Model recognizes two types of elementary fermions: quarks and leptons. In all, the model distinguishes 24 different fermions. There are six quarks (up, down, strange, charm, bottom and top), and six leptons ( See more Composite particles (such as hadrons, nuclei, and atoms) can be bosons or fermions depending on their constituents. More precisely, because of the relation between spin and statistics, a particle containing an odd number of fermions is itself a fermion.

WebSpin-half particles are usually described by the Dirac action. Here a different descrip-tion is presented, invariant under time-reparametrizations and fermion-parametric gauge transformations. We show that this is another counterexample of the Dirac conjecture, and we propose an alternative treatment in the framework of constrained Hamiltonian ... WebApr 24, 2024 · Spin is an intrinsic, unchangeable quantity for an elementary particle. Particles with half-integer spins, s = 1 / 2, 3 / 2, 5 / 2,..., are called fermions, while particles with integer spins, s = 0, 1, 2,… are called bosons. Fermions can only be created or destroyed in particle-antiparticle pairs, whereas bosons can be created or destroyed singly.

WebApr 1, 2024 · Particles with spins that come in half-integer multiples (e.g., ±1/2, ±3/2, ±5/2, etc.) are known as fermions; particles with spins in integer multiples (e.g., 0, ±1, ±2, etc.) are bosons. There... WebA fermion is just a particle of half-integer spin. Being a lepton for a particle is a matter of definition of global symmetries of the theory. This means that a lepton can in principle be both a fermion or a boson, although all known leptons are fermions (electron, muon, tau and their neutrinos).
