Moduli Stabilization in Heterotic M-theory
We examine the stabilization of the two typical moduli, the length ρ of the eleventh segment and the volume V of the internal six manifold, in compactified heterotic M -theory. It is shown that, under certain conditions, the phenomenologically favored vacuum expectation values of ρ and V can be obtained by the combined effects of multi-gaugino condensations on the hidden wall and the membrane i...
متن کاملModuli Stabilization in the Heterotic/IIB Discretuum
We consider supersymmetric compactifications of type IIB and weakly coupled heterotic string-theory in the presence of G resp. H-flux and various nonperturbative effects. We point out that non-perturbative effects change the Hodge structure of the allowed fluxes in type IIB significantly. In the heterotic case it is known that, in contrast to the potential read off from dimensional reduction, t...
متن کاملEnhanced Symmetries of Orbifolds from Moduli Stabilization
We study a supersymmetric field theory in six dimensions compactified on the orbifold T 2/Z2 with two Wilson lines. After supersymmetry breaking, the Casimir energy fixes the shape moduli at fixed points in field space where the symmetry of the torus lattice is enhanced. Localized Fayet-Iliopoulos terms stabilize the volume modulus at a size much smaller than the inverse supersymmetry breaking ...
متن کاملCP Violation and Moduli Stabilization in Heterotic Models 1
The role of moduli stabilization in predictions for CP violation is examined in the context of four-dimensional effective supergravity models obtained from the weakly coupled heterotic string. We point out that while stabilization of compactification moduli has been studied extensively, the determination of background values for other scalars by dynamical means has not been subjected to the sam...
متن کاملHeterotic Orbifolds
A review of orbifold geometry is given, followed by a review of the construction of fourdimensional heterotic string models by compactification on a six-dimensional Z3 orbifold. Particular attention is given to the details of the transition from a classical theory to a first-quantized theory. Subsequently, a discussion is given of the systematic enumeration of all standard-like three generation...
