AdS strings with torsion: Noncomplex heterotic compactifications
- Mathematics
- 2005
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…
The dimensional reduction and Kähler metric of forms in flux and warping
- Physics, Mathematics
- 2013
A bstractWe present a first-principles derivation of the Kähler metric for axion-like moduli of conformally Calabi-Yau compactifications of IIB string theory with imaginary self-dual 3-form flux at…
Model Building and Phenomenology of Flux-Induced Supersymmetry Breaking on D 3-branes
- Physics
- 2004
We study supersymmetry breaking effects induced on D3-branes at singularities by the presence of NSNS and RR 3-form fluxes. First, we discuss some local constructions of chiral models from D3-branes…
Large-volume flux compactifications: Moduli spectrum and D3/D7 soft supersymmetry breaking
- Physics
- 2005
We present an explicit calculation of the spectrum of a general class of string models, corresponding to Calabi-Yau flux compactifications with h1,2 > h1,1 > 1 with leading perturbative and…

Hierarchies from fluxes in string compactifications
- Mathematics
- 2002
Warped compactifications with significant warping provide one of the few known mechanisms for naturally generating large hierarchies of physical scales. We demonstrate that this mechanism is…
Potentials from fluxes
- Mathematics
- 2003
We discuss the compactification of type IIB supergravity with fluxes to generate a potential for the moduli. In particular we resolve an apparent conflict with the no-go theorem for de Sitter space.…
M theory, orientifolds and G - flux
- Mathematics
- 1999
We study the properties of M and F theory compactifications to three and four dimensions with background fluxes. We provide a simple construction of supersymmetric vacua, including some with…
Effective action of string theory flux compactifications
- Physics
- 2004
We discuss four dimensional effective actions of string theory flux compactifications. These effective actions describe four dimensional gravity coupled to overall Kahler modulus of the…
