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.

Simple de Sitter solutions

TL;DR: In this paper, a framework for de Sitter model building in type IIA string theory is presented, illustrated with specific examples, where metastable dS minima of the potential for moduli obtained from a compactification on a product of two Nil three-manifolds combined with orientifolds, branes, fractional Chern-Simons forms, and fluxes are found.

De Sitter vacua from matter superpotentials

TL;DR: In this article, the authors consider the possibility that de Sitter and Minkowski vacua arise due to hidden sector matter interactions and find that the hierarchically small supersymmetry breaking scale can be explained by the scale of gaugino condensation.

The Standard Model from Stable Intersecting Brane World Orbifolds

TL;DR: In this paper, the perturbative stability of non-supersymmetric intersecting brane world models on tori is analyzed and the phenomenological implications of a three generation Standard Model which descends naturally from an SU(5) GUT theory.

Soft supersymmetry breaking in Calabi-Yau orientifolds with D-branes and fluxes

TL;DR: In this paper, the authors compute the N = 1 effective low energy action for a stack of N space-time filling D3-branes in generic IIB Calabi-Yau orientifolds with non-trivial background fluxes by reducing the Dirac-Born-Infeld and Chern-Simons actions.

Type II theories compactified on Calabi–Yau threefolds in the presence of background fluxes

TL;DR: In this paper, the authors derived the bosonic part of the four-dimensional low energy effective action and showed that it is a non-canonical N = 2 supergravity which includes a massive two-form.

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.

Supergravity and a confining gauge theory: duality cascades and χSB-resolution of naked singularities

TL;DR: In this article, a non-singular pure-supergravity background dual to the field theory on all scales, with small curvature everywhere if the ‘t Hooft coupling gsM is large, was proposed.
