Vacuum Energy in Non-Supersymmetric Quasi-Realistic Heterotic-String Vacua with Fixed Moduli
Eman Basaad, Luke A. Detraux, Alonzo R. Diaz Avalos +2
Recently, Baykara, Tarazi and Vafa discussed the existence of quasicrystalline string vacua that contain a single neutral moduli, the dilaton, and studied compactifications of the…

Vacuum Energy of Non-Supersymmetric Heterotic String Models
Luke A. Detraux, Alonzo R. Diaz Avalos, Alon E. Faraggi +1
We use the free fermionic formulation of the heterotic-string in four dimensions to study the vacuum structure and energy of non-supersymmetric tachyon free models that correspond…

Fayet-Iliopoulos D-Term in Non-Supersymmetric Heterotic String Orbifolds
Alonzo R. Diaz Avalos, Alon E. Faraggi, Viktor G. Matyas +1
The Fayet-Iliopoulos -term is a common feature in string vacua that contain an anomalous gauge symmetry, and arises from a one--loop diagram in string per…
