Classification of Heterotic Pati-Salam Models
Benjamin Assel, Kyriakos Christodoulides, Alon E. Faraggi +2
We extend the classification of free fermionic heterotic-string models to vacua in which the SO(10) GUT symmetry is broken at the string level to the Pati-Salam subgroup. Using our…

Exophobic Quasi-Realistic Heterotic String Vacua
Benjamin Assel, Kyriakos Christodoulides, Alon E. Faraggi +2
We demonstrate the existence of heterotic-string vacua that are free of massless exotic fields. The need to break the non-Abelian GUT symmetries in k=1 heterotic-string models by W…
