Non-Tachyonic Semi-Realistic Non-Supersymmetric Heterotic String Vacua
Johar M. Ashfaque, Panos Athanasopoulos, Alon E. Faraggi +1
The heterotic--string models in the free fermionic formulation gave rise to some of the most realistic string models to date, which possess N=1 spacetime supersymmetry. Lack of evi…

Discrete symmetries in the heterotic-string landscape
Panos Athanasopoulos
We describe a new type of discrete symmetry that relates heterotic-string models. It is based on the spectral flow operator which normally acts within a general N=(2,2) model and w…
