Heterotic T-folds with a small number of neutral moduli
Massimo Bianchi, Gianfranco Pradisi, Cristina Timirgaziu +1
We discuss non-geometric supersymmetric heterotic string models in D=4, in the framework of the free fermionic construction. We perform a systematic scan of models with four a prio…
Quasi-realistic heterotic-string models with vanishing one-loop cosmological constant and perturbatively broken supersymmetry?
Gerald B. Cleaver, Alon E. Faraggi, Elisa Manno +1
Quasi-realistic string models in the free fermionic formulation typically contain an anomalous U(1), which gives rise to a Fayet-Iliopoulos D-term that breaks supersymmetry at the…
Orientifold's Landscape: Non-Factorisable Six-Tori
Stefan Forste, Cristina Timirgaziu, Ivonne Zavala
We construct type IIA orientifolds on T6/(Z2 x Z2) which admit non factorisable lattices. We describe a method to deal with this kind of configurations and discuss how the compacti…
Minimal Standard Heterotic String Models
Alon E. Faraggi, Elisa Manno, Cristina Timirgaziu
Three generation heterotic-string vacua in the free fermionic formulation gave rise to models with solely the MSSM states in the observable Standard Model charged sector. The relat…
Z_2 x Z_2 Heterotic Orbifold Models of Non Factorisable Six Dimensional Toroidal Manifolds
Alon E. Faraggi, Stefan Forste, Cristina Timirgaziu
We discuss heterotic strings on Z_2 x Z_2 orbifolds of non factorisable six-tori. Although the number of fixed tori is reduced as compared to the factorisable case, Wilson lines ar…
Internal magnetic fields and supersymmetry in orientifolds
E. Dudas, C. Timirgaziu
Within the context of type I strings, we show the equivalence between BPS D9 branes with internal magnetic fluxes H_i in the three torii and non-BPS D3 branes with inverted interna…
