Supersymmetric sources, integrability and generalized-structure compactifications
- Mathematics
- 2007
In the context of supersymmetric compactifications of type II supergravity to four dimensions, we show that orientifold sources can be compatible with a generalized SU(3) × SU(3)-structure that is…
General N=1 supersymmetric flux vacua of massive type IIA string theory.
- PhysicsPhysical review letters
- 2005
It is shown that such flux vacua exist when the internal geometry is nearly Kähler, and the four-dimensional cosmological constant, while negative, becomes small in the vacuum with the weak string coupling.
Building MSSM flux vacua
- Physics

We construct N=1 and N=0 chiral four-dimensional vacua of flux compactification in Type IIB string theory. These vacua have the common features that they are free of tadpole instabilities (both NSNS…
A new family of non-homogeneous type IIA flux vacua from AdS4/CFT3

In arXiv:0901.0969 a set of three-dimensional Chern-Simons-matter theories with different amounts of global symmetry and supersymmetry is introduced, which deform the ABJM construction to include…
Moduli stabilization and cosmology of type IIB on SU(2)-structure orientifolds
- Mathematics
- 2009
We consider type IIB flux compactifications on six-dimensional SU(2)-structure manifolds with O5- and O7-planes. These six-dimensional spaces allow not only for F3 and H3 fluxes but also for F1 and…
Generalized non-supersymmetric flux vacua
- Mathematics
- 2008
We discuss a novel strategy to construct 4D = 0 stable flux vacua of type II string theory, based on the existence of BPS bounds for probe D-branes in some of these backgrounds. In particular, we…
A second look at = 1 supersymmetric AdS4 vacua of type IIA supergravity
- Mathematics

We show that a class of type IIA vacua recently found within the D=4 effec- tive approach corresponds to compactification on AdS 4 ×S 3 ×S 3 /Z 3 . The results obtained using the effective method…

In this paper we consider compactifications of massive type IIA supergravity on manifolds with SU(3) structure. We derive the gravitino mass matrix of the effective four-dimensional N=2 theory and…

We discuss a generalized form of IIA/IIB supergravity depending on all R-R potentials C-(p) (p = 0, 1,..., 9) as the effective field theory of type IIA/IIB superstring theory. For the IIA case we…
Notes on SU(3) structures in type IIB supergravity

We study solutions of type IIB supergravity with an SU(3) structure group and four dimensional Poincare invariance and present relations among the bosonic fields which follow from the supersymmetry…
Chiral 4d string vacua with D branes and NSNS and RR fluxes
- Mathematics
- 2003
We discuss type-IIB orientifolds with D-branes, and NSNS and RR field strength fluxes. The D-brane sectors lead to open string spectra with non-abelian gauge symmetry and charged chiral fermions. The…

Intersecting Dp-branes often give rise to chiral fermions living on their intersections. We study the construction of four-dimensional chiral gauge theories by considering configurations of type II…

We analyse the geometrical structure of supersymmetric solutions of type II supergravity of the form 1,9−n×Mn with non-trivial NS flux and dilaton. Solutions of this type arise naturally as the…
