Classification of the Chiral Z_2 x Z_2 Heterotic String Models
S. E. M. Nooij
This thesis provides a classification of the chiral content of the heterotic $\mathbbm{Z}_2 \times \mathbbm{Z}_2$ orbifold models. We show that the chiral content of the heterotic…
Classification of the chiral Z2XZ2 fermionic models in the heterotic superstring
A. E. Faraggi, C. Kounnas, S. E. M. Nooij +1
The first particle physics observable whose origin may be sought in string theory is the triple replication of the matter generations. The class of Z2XZ2 orbifolds of six dimension…
Towards the classification of Z2XZ2 fermionic models
A. E. Faraggi, C. Kounnas, S. E. M. Nooij +1
We develop a formalism that allows a complete classification of four-dimensional Z2XZ2 heterotic string models. Three generation models in a sub-class of these compactifications ar…
NAHE-based string models with SU(4) X SU(2) X U(1) SO(10) Subgroup
Gerald B. Cleaver, Alon E. Faraggi, Sander Nooij
The orbifold GUT doublet-triplet splitting mechanism was discussed in 1994 in the framework of the NAHE-based free fermionic models in which the SO(10) GUT symmetry is broken to SO…
