of heterotic string and 6 D SO ( 14 ) flavor unification model
نویسنده
چکیده
A 6D SO(14) flavor unification model with two spinor representations is obtained by a Z2 orbifold compactification of the heterotic string, and the N = 4 supersymmetry is reduced to N = 2. This 6D model reduces to the previous 5D SO(14) model of family unification after the S1 compactification. [

of heterotic string and 6 D SO ( 16 ) and E 7 × SU ( 2 ) flavor unification models
A Z2 orbifold compactification of the heterotic string is considered. The resulting 6D GUT groups can be SO(16) or E7 × SU(2) plus some hidden sector groups. The N = 4 supersymmetry is reduced to N = 2. In particular, the SO(16) 6D model with one spinor representation 128 can reduce to the previous 5D SO(16) or SO(14) family unification models after compactifying the sixth dimension. To obtain ...

متن کاملPhenomenological survey of free fermionic heterotic–string models
A glossary overview of the phenomenological studies of quasi–realistic free fermionic heterotic string models is presented. I elaborate on the correspondence of these models with Z2 × Z2 orbifolds. Introduction The standard model of particle physics passes all experimental observations with flying colors. The gauge charges of the standard model matter states are strongly suggestive of the embed...
متن کاملThree-Family SO(10) Grand Unification in String Theory.
The construction of a supersymmetric SO(10) grand unification with 5 lefthanded and 2 right-handed families in the four-dimensional heterotic string theory is presented. The model has one SO(10) adjoint Higgs field. The SO(10) current algebra is realized at level 3.
متن کاملTrinification from Superstring toward Mssm
Even though the standard model(SM) is very successful, there exists the sofar unsolved family problem that there are 3 sets of fifteen chiral fields. “Is 3 a very fundamental number in the universe?” We try to investigate this problem. A grand unification(GUT) in SO(10) is very promising, but it has only one family. To have three families, one has to repeat the representations, which we want to...
