Definitions and meanings of "Fermion"

What do we mean by fermion?

Any of a class of particles having a spin that is half an odd integer and obeying the exclusion principle, by which no more than one identical particle may occupy the same quantum state. The fermions include the baryons, quarks, and leptons. noun

Any particle that obeys Fermi-Dirac statistcs and is subject to the Pauli exclusion principle. noun

A particle with totally antisymmetric composite quantum states, which means it must obey the Pauli exclusion principle and Fermi-Dirac statistics. They have half-integer spin. Among them are many elementary particles, most derived from quarks. Compare boson. noun

Any particle that obeys Fermi-Dirac statistics and is subject to the Pauli exclusion principle noun

(Standard Model) 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.

The word "fermion" in example sentences

At low energies the Higgs gets a vacuum expectation value, and acts like a mass term, converting the left-handed fermion into a right-handed fermion, which is what you want. ❋ Sean (2008)

The paper laid the basis for describing one of the two categories of the elementary particles that make up an atom - one was boson, and the other came to be known as fermion, after the Italian physicist Enrico Fermi. ❋ Unknown (2008)

Assuming that this is no error, then the term "fermion" is ambiguous between elementary particle and composite particle. ❋ Horace Jeffery Hodges (2005)

The phase here is between a heavy fermion and light fermions in an anti-ferromagnetic state. ❋ Unknown (2010)

The existence of the superpartner to the Higgs and the fermion field at about the same mass scale results in the cancellation of these divergences. ❋ Unknown (2009)

So a Higgs field that couples to the fermion field f and its conjugate f-bar according to an interaction term in the Lagrangian ~ f-barHf, will carry the Higgs divergence as well. ❋ Unknown (2009)

It think these internal fermion degrees of freedom behave as Landau electrons around a quantum critical point. ❋ Unknown (2009)

Also, one assumes the duality accounts for the discrete spectrum of possible fermion rest masses (perhaps corresponding to a discrete spectrum of possible closed black hole assemblies?) ❋ Sean (2008)

The mass scale characterizing each Kaluza-Klein tower can be chosen independently for each species of scalar, fermion, or gauge boson. ❋ Sean (2008)

In that language there is no fermion propagator and no Higgs insertion - the effect of the Higgs has been summed into our definition of the massive fermion. ❋ Sean (2008)

That language is very useful in order to keep track of fermion chiralities (which in this example is what tells you the whole graph is proprtional to the fermion mass), but it is not really intended for serious calculations. ❋ Sean (2008)

You might think that you could just have a single SU (2) L or U (1) hypercharge gauge boson connect that loop to the Standard Model fermion ψ, but that vanishes by gauge invariance; you need two gauge bosons, and thus two loops. ❋ Sean (2008)

What I mean is that one can just think of the four-component fermion which contains both and. ❋ Sean (2008)

We need to explicitly construct a “chiral fermion measure” as a function of the lattice gauge field such that the resulting chiral fermion determinant is gauge invariant in fermion representations satisfying the usual anomaly cancellation conditions. ❋ Sean (2007)

Another big problem will be that the chiral fermion determinants are complex-valued - numerical lattice simulation methods require real (positive) fermion determinants. ❋ Sean (2007)

There are certain quite distinctive features of the standard model (gauge groups, representations, fermion mass matrices), which if you came up with a model which uniquely determined them, it might be convincing you were on to something (just getting the number 3 of generations is not like this). ❋ Sean (2007)

The well-defined fermion/boson distinction is not precisely equivalent to the more casual stuff/force distinction, because relativity teaches us that the bosonic “force fields” are also sources for the forces themselves. ❋ Sean (2007)

You can get virtually any number of generations, any gauge group, any fermion representations, any Yukawa couplings, etc. ❋ Sean (2007)

The naive lattice discretization of the Dirac operator gives rise to “doublers” (spurious fermion species) and N-N basically says that there is no way to fix this without ruining the chiral nature of the theory, i.e. ruining the possibility to decompose the massless lattice fermion action into decoupled left - and right-handed pieces. ❋ Sean (2007)

I see no reason why constraints imposed to get consistency at the Planck scale should imply any constraints on gauge groups, choices of fermion and scalar representations, and parameters of low energy effective field theories, apart from those that could be deduced by the principles of effective field theory, without string theory or quantum gravity. ❋ Sean (2007)
