Flipped SU(5) — The Flipped SU(5) model is a GUT theory which states that the gauge group is: [ SU(5) times; U(1)χ ] /mathbb{Z} 5 Fermions form three families, each consisting of the representations ar{5} { 3} for the lepton doublet, L, and the up quarks u^c;… … Wikipedia
Non-linear sigma model — In quantum field theory, a nonlinear σ model describes a scalar field Σ which takes on values in a nonlinear manifold called the target manifold T. The target manifold is equipped with a Riemannian metric g. Σ is a differentiable map from… … Wikipedia
SO(10) (physics) — In particle physics, one of the grand unified theories (GUT) is based on the SO(10) Lie group. (The Lie group involved is not really the special orthogonal group SO(10), but rather its double cover Spin(10); but calling it SO(10) is the standard… … Wikipedia
Regularization (physics) — In physics, especially quantum field theory, regularization is a method of dealing with infinite, divergent, and non sensical expressions by introducing an auxiliary concept of a regulator (for example, the minimal distance epsilon in space which … Wikipedia
Nambu-Jona-Lasinio model — In quantum field theory, the Nambu Jona Lasinio model (named for its developers Yoichiro Nambu and Giovanni Jona Lasinio) is a theory of interacting Dirac fermions with chiral symmetry. It is an example of a four fermion interaction. This model… … Wikipedia
Flipped SO(10) — is a grand unified theory which is to standard SO(10) as flipped SU(5) is to SU(5).Recall that in conventional SO(10) models, the fermions lie in three spinorial 16 representations, one for each generation, which decomposes under [SU(5) times;… … Wikipedia
UV fixed point — A theory has a UV fixed point if its renormalization group flow runs towards a fixed point in the ultraviolet (i.e. short length scale/large energy) limit. Among other things, it means that such a theory is not an effective field theory because… … Wikipedia
