Flat directions in three-generation free-fermionic string models / Cleaver, Gerald (Pennsylvania U.) ; Cvetic, Mirjam (Pennsylvania U.) ; Espinosa, Jose R. (CERN ; Pennsylvania U.) ; Everett, Lisa L. (Pennsylvania U.) ; Langacker, Paul (Pennsylvania U.)
In quasi-realistic string models that contain an anomalous U(1) the non-zero Fayet-Iliopoulos term triggers the shifting of the original vacuum to a new one along some flat direction, so that SUSY is preserved but the gauge group is partially broken. The phenomenological study of these models thus requires as a first step the mapping of the space of flat directions. [...]

Classification of Flat Directions in Perturbative Heterotic Superstring Vacua with Anomalous U(1) / Cleaver, G ; Cvetic, M ; Espinosa, J R ; Everett, L ; Langacker, P G
We develop techniques to classify D- and F-flat directions for N=1 supersymmetric string vacua of the perturbative heterotic string theory, which possess an anomalous U(1) gauge group at the tree level. Genus-one corrections generate a Fayet-Iliopoulos term for the D-term of U(1)_A, which is canceled by non-zero vacuum expectation values (VEVs) of certain massless multiplets in such a way that the anomalous U(1) is broken, while maintaining the D- and F-flatness of the effective field theory.

Flat Directions in Flipped SU(5); 1, All-Order Analysis / Cleaver, G.B. (Texas A-M ; HARC, Woodlands) ; Ellis, John R. (CERN) ; Nanopoulos, Dimitri V. (Texas A-M ; HARC, Woodlands ; Athens Academy)
We present a systematic classification of field directions for the string-derived flipped SU(5) model that are D- and F-flat to all orders. Properties of the flipped SU(5) model with field values in these directions are compared to those associated with other flat directions that have been shown to be F-flat to specific finite orders in the superpotential.
