Fermion meaning
Any elementary or composite particle that has half-integer spin and thus obeys Fermi–Dirac statistics and the Pauli exclusion principle (equivalently, a particle for which the wavefunction of any system of identical such particles changes sign whenever two are swapped); a baryon, a lepton or a quark; | Any elementary or composite particle that has half-integer spin and thus obeys Fermi–Dirac statistics and the Pauli exclusion principle (equivalently, a particle for which the wavefunction of any system of identical such particles changes sign whenever two are swapped); a baryon, a lepton or a quark; (slightly more loosely) any such particle or any composite particle composed of fermions. | any such particle or any composite particle composed of fermions.

Dirac concludes with the prophetic words "We have boson variables appearing automatically in a theory that starts with only fermion variables, provided the number of fermion variables is infinite.
This is also why two particles that are bound to each other in some way can be a fermion: again, their total quantum spin needs to have a half-integer value.
He suggested that beta decay could be explained by a four- fermion interaction, involving a contact force with no range. citation citation However, it is better described as a non-contact force field having a finite range, albeit very short.
If multiple fermions have the same spatial probability distribution, then at least one property of each fermion, such as its spin, must be different.
More precisely, because of the relation between spin and statistics, a particle containing an odd number of fermions is itself a fermion.
Most GUT models also fail to explain the little hierarchy between the fermion masses for different generations.
One of the few possible experimental tests of certain GUT is proton decay and also fermion masses.
Russian physicist Lev Landau used the idea for the Fermi liquid theory wherein low energy properties of interacting fermion systems were given in terms of what are now known as Landau-quasiparticles.
Since bosons carry one unit of angular momentum, the fermion's spin direction will flip from + 1 2 to − 1 2 (or vice versa) during such an exchange (in units of the reduced Planck's constant ).
Supersymmetry Supersymmetry assumes that every fundamental fermion has a superpartner that is a boson and vice versa.
The h term describes the Higgs field F. : The y term gives the Yukawa interaction that generates the fermion masses after the Higgs acquires a vacuum expectation value.
The main reason for this complexity lies in the difficulty of reproducing the observed fermion masses and mixing angles.
The remarkable notion of an antiparticle to each fermion particle – e.g. the positron as antiparticle to the electron – stems from his equation.
This is because the standard model fails to incorporate the force of gravity and because of problems such as the hierarchy problem and the inability to explain the structure of fermion masses or dark matter.
