of heterotic string and 6 D SO ( 16 ) and E 7 × SU ( 2 ) flavor unification models

چکیده
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 one spinor, we have to take into account the left-over center of SO(16). We also comment on the E7 × SU(2) model. [

متن کاملof heterotic string and 6 D SO ( 14 ) flavor unification model
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. [
متن کاملA Classification of Three - Family SO ( 10 ) and E 6 Grand Unification in String Theory
We give a classification of 3-family SO(10) and E6 grand unification in string theory within the framework of conformal field theory and asymmetric orbifolds. We argue that the construction of such models in heterotic string theory requires certain Z6 asymmetric orbifolds that include a Z3 outerautomorphism, the latter yielding a level-3 current algebra for the grand unification gauge group SO(...
متن کاملDual Models of Gauge Unification in Various Dimensions
We construct a compactification of the heterotic string on an orbifold T 6/Z6 leading to the standard model spectrum plus vector–like matter. The standard model gauge group is obtained as an intersection of three SO(10) subgroups of E8. Three families of SO(10) 16-plets are localized at three equivalent fixed points. Gauge coupling unification favours existence of an intermediate GUT which can ...

We give a classification of 3-family SO(10) and E6 grand unification in string theory within the framework of conformal (free) field theory and asymmetric orbifolds. We argue that the construction of such models in the heterotic string theory requires certain Z6 asymmetric orbifolds that include a Z3 outer-automorphism, the latter yielding a level-3 current algebra for the grand unification gau...
