Hierarchies from fluxes in string compactifications
TLDR
In this article, the authors show that the hierarchy of scales can be fixed by a choice of Ramond-Ramond and Neveu-Schwarz fluxes in the compact manifold, and give examples involving orientifold compactifications of type IIB string theory and F-theory compactifications on Calabi-Yau fourfolds.Abstract:
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 realizable in string theory, and give examples involving orientifold compactifications of type-IIB string theory and F-theory compactifications on Calabi-Yau fourfolds. In each case, the hierarchy of scales is fixed by a choice of Ramond-Ramond and Neveu-Schwarz fluxes in the compact manifold. Our solutions involve compactifications of the Klebanov-Strassler gravity dual to a confining $\mathcal{N}=1$ supersymmetric gauge theory, and the hierarchy reflects the small scale of chiral symmetry breaking in the dual gauge theory.read more

On classical de Sitter vacua in string theory
Timm Wrase,Marco Zagermann +1 more
TL;DR: In this paper, the authors review the prospect of obtaining tree-level de Sitter vacua and slow-roll inflation models in string compactifications, focusing on two well-controlled classes that lead to an effective 4D, = 1 supergravity description: Type IIA theory on group or coset manifolds with SU(3)-structure and O6-planes, as well as type IIB compactifications on SU(2)-structures with O5-and O7-planes.

Higher-derivative supergravity and moduli stabilization
TL;DR: In this paper, the ghost-free four-derivative terms for chiral superfields were discussed and compared in terms of supersymmetry and supergravity, and it was shown that only one of them is consistent with the principles of effective field theory.

General axisymmetric solutions and self-tuning in 6D chiral gauged supergravity
TL;DR: In this article, the authors re-examine the properties of axially-symmetric solutions to chiral gauged 6D supergravity, and show that not all of these solutions have purely conical singularities at the brane positions.

The Large N limit of superconformal field theories and supergravity
TL;DR: In this article, it was shown that the large-N limits of certain conformal field theories in various dimensions include in their Hilbert space a sector describing supergravityon the product of anti-de Sitter spacetimes, spheres, and other compact manifolds.

Large Mass Hierarchy from a Small Extra Dimension
TL;DR: In this paper, the weak scale is generated from the Planck scale through an exponential hierarchy, but this exponential arises not from gauge interactions but from the background metric, which is a slice of spacetime.

An Alternative to compactification
TL;DR: In this paper, a single 3-brane embedded in five dimensions was shown to reproduce four-dimensional Newtonian and general relativistic gravity to more than adequate precision, even without a gap in the Kaluza-Klein spectrum.
