The problem of the stabilization of moduli is discussed within the context of compactified strongly coupled heterotic string theory. It is shown that all geometric, vector bundle, and five-brane moduli are completely fixed, within a phenomenologically acceptable range, by nonperturbative physics. This result requires, in addition to the full space of moduli, nonvanishing Neveu-Schwarz flux, gaugino condensation with threshold corrections, and the explicit form of the Pfaffians in string… 
Stringy corrections to Kahler potentials, SUSY breaking, and the cosmological constant problem
The moduli of N = 1 compactifications of IIB string theory can be stabilized by a combination of fluxes (which freeze complex structure moduli and the dilaton) and nonperturbative superpotentials
Stabilizing moduli with a positive cosmological constant in heterotic M-theory
It is shown that strongly coupled heterotic M-theory with anti-five-branes in the S1/2 bulk space can have meta-stable vacua which break N = 1 supersymmetry and have a small, positive cosmological
AdS strings with torsion: Noncomplex heterotic compactifications
Combining the effects of fluxes and gaugino condensation in heterotic supergravity, we use a ten-dimensional approach to find a new class of four-dimensional supersymmetric AdS4 compactifications on
Systematics of moduli stabilisation in Calabi-Yau flux compactifications
We study the large volume limit of the scalar potential in Calabi-Yau flux compactifications of type IIB string theory. Under general circumstances there exists a limit in which the potential
Type IIA Moduli Stabilization
We demonstrate that flux compactifications of type IIA string theory can classically stabilize all geometric moduli. For a particular orientifold background, we explicitly construct an infinite
A ug 2 00 7 Moduli stabilization in heterotic M-theory
We reconsider the ingredients of moduli stabilization in heterotic M-theory. On this line we close a gap in the literature deriving the Kähler potential dependence on vector bundle moduli and charged
Gaugino condensation and the cosmological constant
A bstractThe existence of de Sitter solutions in string theory is strongly constrained by no-go theorems. We continue our investigation of corrections to the heterotic effective action, with the aim
Heterotic Moduli Stabilization with Fractional Chern-Simons Invariants
We show that fractional flux from Wilson lines can stabilize the moduli of heterotic string compactifications on Calabi-Yau threefolds. We observe that the Wilson lines used in GUT symmetry breaking


A Moduli Fixing Mechanism in M theory
We study M theory compactifications on manifolds of $G_2$-holonomy with gauge and matter fields supported at singularities. We show that, under certain topological conditions, the combination of

Five-branes and supersymmetry breaking in M theory
Supersymmetry breaking via gaugino condensation is studied in vacua of heterotic M-theory with five-branes. We show that supersymmetry is still broken by a global mechanism and that the
Phenomenological survey of M theory
The Standard Model data suggests that the quantum gravity vacuum should accommodate two pivotal ingredients. The existence of three chiral generations and their embedding in chiral 16 SO(10)
Heterotic string theory on non‐Kähler manifolds with H‐flux and Gaugino condensate
We discuss compactifications of heterotic string theory to four dimensions in the presence of H–fluxes, which deform the geometry of the internal manifold, and a gaugino condensate which breaks
