Orbifold Breaking of Left-Right Gauge Symmetry
We study the five dimensional left-right symmetric gauge theory in which the gauge symmetry is broken down through orbifold compactification to four dimensions. The right handed charged gauge boson, WR is a Kaluza-Klein excited state in this model, and unlike the usual left-right symmetric model in four dimension, there is no mixing in the charged sector. We develop the formalism and give expre...
متن کاملLeptogenesis from Right-handed Neutrino Decays to Right-handed Leptons
We investigate what would be the consequences for leptogenesis of the existence of a charged SU(2)L singlet scalar δ . If such a scalar particle exists it allows the right-handed neutrinos to couple not only to left-handed lepton and Higgs doublets as in ordinary leptogenesis, but also to a right-handed charged lepton and a δ. This provides a new source of leptogenesis which can be successful i...
متن کاملOn minimal realization of IF-languages: A categorical approach
he purpose of this work is to introduce and study the concept of minimal deterministic automaton with IF-outputs which realizes the given IF-language. Among two methods for construction of such automaton presented here, one is based on Myhill-Nerode's theory while the other is based on derivatives of the given IF-language. Meanwhile, the categories of deterministic automata with IF-outputs and ...
متن کاملMinimal gauge-Higgs unification with a flavour symmetry
We show that a flavour symmetry à la Froggatt-Nielsen can be naturally incorporated in models with gauge-Higgs unification, by exploiting the heavy fermions that are anyhow needed to realize realistic Yukawa couplings. The case of the minimal five-dimensional model, in which the SU(2)L×U(1)Y electroweak group is enlarged to an SU(3)W group, and then broken to U(1)em by the combination of an orb...
متن کاملRight-Handed Sector Leptogenesis
Instead of creating the observed baryon asymmetry of the universe by the decay of right-handed (RH) neutrinos to left-handed leptons, we propose to generate it dominantly by the decay of the RH neutrinos to RH leptons. This mechanism turns out to be successful in large regions of parameter space. It may work, in particular, at a scale as low as ∼ TeV, with no need to invoke quasi-degenerate RH ...
