A Three - Family SU ( 4 ) c ⊗ SU ( 2 ) w ⊗ U ( 1 ) Type I Vacuum

چکیده
We construct a four dimensional chiral N = 1 space-time supersymmetric perturbative Type I vacuum corresponding to a compactification on a toroidal Z2 ⊗ Z2 ⊗ Z3 orbifold with a discrete Wilson line. This model is non-perturbative from the heterotic viewpoint. It has three chiral families in the SU(4)c⊗SU(2)w ⊗U(1) subgroup of the total gauge group. We compute the tree-level superpotential in this model. There appears to be no obvious obstruction to Higgs the gauge group down to SU(3)c⊗SU(2)w ⊗U(1)Y and obtain the Standard Model gauge group with three chiral families.

متن کاملQuantum Weakdynamics as an SU(3)I Gauge Theory: Grand Unification of Strong and Electroweak Interactions
Quantum weakdynamics (QWD) as an SU(3)I gauge theory with the Θ vacuum term is considered to be the unification of the electroweak interaction as an SU(2)L × U(1)Y gauge theory. The grand unification of SU(3)I × SU(3)C beyond the standard model SU(3)C × SU(2)L × U(1)Y is established by the group SU(3)I . The grand unified interactions break down to weak and strong interactions at a new grand un...
متن کاملAn Orbifold Compactification with Three Families from Twisted Sectors
We obtain a three generational SU(3)c × SU(3)w ×U(1) 4 × [SO(12)×U(1)2]′ model from an orbifold construction with the requirement that three generations arise from twisted sectors. There exist supersymmetric vacua realizing the standard model. In one example the anomalous U(1) breaks the gauge symmetry down to SU(3)c × SU(2)w × U(1)Y × SO(12) .
متن کاملVacuum structure and dynamical symmetry breaking in gauge-Higgs unification models
We study the vacuum structure and dynamical symmetry breaking in the gaugeHiggs unification of the 5D theory compactified on an orbifold, S/Z2. This theory identifies Wilson line degrees of freedoms as “Higgs doublets”. We consider SU(3)c × SU(3)W and SU(6) models with the compactification scale of order a few TeV. The gauge symmetries are reduced to SU(3)c × SU(2)L × U(1)Y and SU(3)c × SU(2)L ...
متن کاملThree Generations in Type I Compactifications
Generalizing the recent work on three-family Type I compactifications, we classify perturbative Type I vacua obtained via compactifying on the T 6/Z2 ⊗ Z2 ⊗ Z3 orbifold with all possible Wilson lines. In particular, we concentrate on models with gauge groups containing the Standard Model gauge group SU(3)c ⊗ SU(2)w ⊗ U(1)Y as a subgroup. All of the vacua we obtain contain D5-branes and are non-...
