http://www.particleadventure.org/fermibos.html 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 … Meer weergeven 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 ( Meer weergeven 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 … Meer weergeven • Anyon, 2D quasiparticles • Chirality (physics), left-handed and right-handed • Fermionic condensate • Weyl semimetal • Fermionic field Meer weergeven WebMesons are intermediate mass particles which are made up of a quark-antiquark pair.

The neutral pion (π 0 ), … WebThe crucial concepts of the SM are those of gauge fields and of chiral fermions: they correspond to two basic notions of NCG, namely connections and Dirac operators. Indeed, the algebraic definition of linear connection is imported verbatim into NCG. Chiral fermions, for their part, are acted on by Dirac and Dirac–Weyl operators.
