CLNS 96/1413 Asymmetric Orbifolds and Grand Uni cation
نویسندگان
چکیده
We generalize the rules for the free fermionic string construction to include other asymmetric orbifolds with world-sheet bosons. We use these rules to construct various grand uni ed string models that involve level-3 current algebras. We present the explicit construction of three classes of 3-chiral-family grand uni ed models in the heterotic string theory. Each model has 5 lefthanded, and two right-handed families, and an adjoint Higgs. Two of them are SO(10) and the third is E6. With Wilson lines and/or varying moduli, we show how other 3-family grand uni ed models, such as SO(10) and SU(5), may be constructed from them.

CLNS 96/1414 Asymmetric Non-Abelian Orbifolds and Model Building
The rules for the free fermionic string model construction are extended to include general non-abelian orbifold constructions that go beyond the real fermionic approach. This generalization is also applied to the asymmetric orbifold rules recently introduced. These non-abelian orbifold rules are quite easy to use. Examples are given to illustrate their applications. Typeset using REVTEX ∗zurab@...
متن کاملA Classification of 3 - Family Grand Unification in String Theory II . The SU ( 5 ) and SU ( 6 ) Models
Requiring that supersymmetric SU(5) and SU(6) grand unifications in the heterotic string theory must have 3 chiral families, adjoint (or higher representation) Higgs fields in the grand unified gauge group, and a non-abelian hidden sector, we construct such string models within the framework of free conformal field theory and asymmetric orbifolds. Within this framework, we construct all such st...

متن کاملEUROPEAN ORGANIZATION FOR NUCLEAR RESEARCH Consistency Checks of Grand Uni ed Theories
The world averaged values of the electroweak and strong couplings and the lower limits on the proton lifetime are used for consistency checks of Grand Uni ed Theories (GUT). It is con rmed that new physics outside the Standard Model (SM) is required to obtain uni cation of the electroweak and strong forces. Such new physics could come from the minimal supersymmetric extension of the SM, which p...
