Three family Z 3 orbifold trinification , MSSM and doublet - triplet splitting problem

چکیده
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. [

A Solution to the Doublet-Triplet Splitting Problem in the Type IIB Supergravity
The doublet–triplet mass splitting problem is one of the most serious problems in supersymmetric grand unified theories (GUTs). A class of models based on a product gauge group, such as the SU(5)GUT×U(3)H or the SU(5)GUT×U(2)H, realize naturally the desired mass splitting that is protected by an unbroken R symmetry. It has been pointed out that various features in the models suggest that these ...

We suggest a simple grand unified theory where the fifth dimensional coordinate is compactified on an S1/(Z2 × Z ′ 2) orbifold. This model is based on the supersymmetric flipped SU(5) × U(1) grand unified theory, which can realize not only the triplet-doublet splitting but also the natural fermion mass hierarchies. The triplet-doublet splitting is realized by S1/(Z2 × Z ′ 2) orbifolding, which ...

متن کاملNew Solution to Doublet - Triplet Splitting Problem in SU ( N ) SUSY GUTs : Towards an Unification of Flavour
The missing VEV solution to the doublet-triplet splitting problem in general SU(N) SUSY GUTs is found. Remarkably enough, it requires a strict equality of numbers of the fundamental colours and flavours in SU(N) and for the even-order groups (N=2k) gives the predominant breaking channel SU (N) −→ SU (k−1) c ⊗SU (k−1) f ⊗SU (2) w ⊗U (1)⊗U (1) ′ in the parameter natural area. The flavour subsymme...
