Totally asymptotically free trinification

چکیده
Motivated by new ideas about the Higgs mass naturalness problem, we present realistic TeV-scale extensions of the Standard Model, into the gauge group SU(3)L ⊗ SU(3)R ⊗ SU(3)c, such that all gauge, Yukawa and quartic couplings can be extrapolated up to infinite energy. Three generations of chiral fermions and Higgses are needed, as well as some extra fermion.

Trinification with sin 2 θ W = 3 8 and seesaw neutrino mass
We realize a supersymmetric trinification model with three families of (27tri + 27tri + 27tri) by the Z3 orbifold compactification with two Wilson lines. It is possible to break the trinification group to the supersymmetric standard model. This model has several interesting features: the hypercharge quantization, sin θ0 W = 3 8 , naturally light neutrino masses, and introduction of R-parity. Th...
متن کاملThree family Z 3 orbifold trinification , MSSM and doublet - triplet splitting problem
A Z3 orbifold compactification of E8×E′ 8 heterotic string is considered toward a trinification SU(3)3 with three light families. The GUT scale VEV’s of the SU(2)W ×U(1)Y × SU(3)c singlet chiral fields in two sets of the trinification spectrum allow an acceptable symmetry breaking pattern toward MSSM. We show that a doublet-triplet splitting is related to the absence of a ∆B nonzero operator. [
متن کاملA D-brane inspired U(3)C × U(3)L × U(3)R model
Motivated by D-brane scenarios, we consider a non-supersymmetric model based on the gauge symmetry U (3) C ×U (3) L ×U (3) R which is equivalent to the SU (3) 3 " trinification " model supplemented by three U (1)s. Two U (1) combinations are anomalous while the third U (1) Z ′ is anomaly free and contributes to the hypercharge generator. This hypercharge embedding correspods to sin 2 θ W = 6 19...
متن کاملDark Matter in Minimal Trinification
We study an example of Grand Unified Theory (GUT), known as trinification, which was first introduced in 1984 by S.Glashow. This model has the GUT gauge group as [SU(3)] with a discrete Z3 to ensure the couplings are unified at the GUT scale. In this letter we consider this trinification model in its minimal formulation and investigate its robustness in the context of cosmology. In particular w...
متن کاملStrong convergence theorems of the Halpern-Mann’s mixed iteration for a totally quasi-φ-asymptotically nonexpansive nonself multi-valued mapping in Banach spaces
In this paper, we introduce a class of totally quasi-φ-asymptotically nonexpansive nonself multi-valued mapping to modify the Halpern-Mann-type iteration algorithm for a totally quasi-φ-asymptotically nonexpansive nonself multi-valued mapping, which has the strong convergence under a limit condition only in the framework of Banach spaces. Our results are applied to study the approximation probl...
