orbifold compactification as the origin of realistic free fermionic models
نویسنده
چکیده
I discuss the correspondence between realistic four dimensional free fermionic models and Z2 × Z2 orbifold compactification. I discuss the properties of the Z2 × Z2 orbifold that are reflected in the realistic free fermionic models. I argue that the properties of the realistic free fermionic models arise due to the underlying Z2×Z2 orbifold compactification with nontrivial background fields. I suggest that three generation is a natural outcome of Z2 × Z2 orbifold compactification with “standard embedding” and at the point in compactification space that corresponds to the free fermionic formulation. I discuss how quark flavor mixing is related to the compactification. ∗ e–mail address: [email protected]

متن کاملThe Origin of Realistic Free Fermionic Models
All the realistic free fermionic models utilize a set of basis vectors, the NAHE set, that correspond to Z 2 × Z 2 orbifold compactification with nontrivial background fields. I argue that the realistic features of free fermionic models, like the number of generations and the fermion mass spectrum are due to the underlying Z 2 × Z 2 orbifold compactification. As a unified theory of gravity and ...
متن کاملGeneration Mass Hierarchy in Superstring Derived Models
I discuss the problem of generation mass hierarchy in the context of realistic superstring models which are constructed in the free fermionic formulation. These models correspond to models which are compactified on Z2 × Z2 orbifold. I suggest that the hierarchy among the generations results from horizontal symmetries, which arise from the compactification. In particular, I show that in a class ...
متن کاملLight Fermion Masses in Superstring Derived Standard–like Models
I discuss the suppression of the lightest generation fermion mass terms in realistic superstring standard–like models in the free fermionic formulation. The suppression of the mass terms is a consequence of horizontal symmetries that arise due to the Z2 × Z2 orbifold compactification. In a specific model I investigate the possibility of resolving the strong CP puzzle by a highly suppressed up q...
