Spinor-Vector Duality in fermionic Z2XZ2 heterotic orbifold models
Alon E. Faraggi, Costas Kounnas, John Rizos
We continue the classification of the fermionic Z2XZ2 heterotic string vacua with symmetric internal shifts. The space of models is spanned by working with a fixed set of boundary…
Chiral family classification of fermionic Z2xZ2 heterotic orbifold models
Alon E. Faraggi, Costas Kounnas, John Rizos
Free fermionic construction of four dimensional string vacua, are related to the Z2XZ2 orbifolds at special points in the moduli space, and yielded the most realistic three family…
Fluxes, Gaugings and Gaugino Condensates
J. -P. Derendinger, C. Kounnas, P. M. Petropoulos
Based on the correspondence between the N = 1 superstring compactifications with fluxes and the N = 4 gauged supergravities, we study effective N = 1 four-dimensional supergravity…
Gaugino Condensates and Fluxes in N = 1 Effective Superpotentials
Jean-Pierre Derendinger, Costas Kounnas, P. Marios Petropoulos
In the framework of orbifold compactifications of heterotic and type II orientifolds, we study effective N = 1 supergravity potentials arising from fluxes and gaugino condensates.…
