Axion Stabilization in Type IIB Flux Compactifications

چکیده

A scenario for stabilization of axionic moduli fields in the context of type IIB Calabi-Yau flux compactifications is discussed in detail. We consider the case of a Calabi-Yau orientifold with h − 6= 0 which allows for the presence of B2 and C2moduli. In an attempt to generalize the KKLT and the Large Volume Scenario, we show that these axions can also be stabilized some already at tree level, and others when we include perturbative α′-corrections to the Kähler potentialK and nonperturbative D3-instanton contributions to the superpotential W . At last, we comment on the possible influence of worldsheet instantons on the process of moduli stabilization.

Eternal Inflation with α′-Corrections

Higher-order α-corrections are a generic feature of type IIB string compactifications. In KKLT-like models of moduli stabilization they provide a mechanism of breaking the noscale structure of the volume modulus. We present a model of inflation driven by the volume modulus of flux compactifications of the type IIB superstring. Using the effects of gaugino condensation on D7-branes and perturbat...

Extremal Black Hole and Flux Vacua Attractors

These lectures provide a pedagogical, introductory review of the so-called Attractor Mechanism (AM) at work in two different 4-dimensional frameworks: extremal black holes in N = 2 supergravity and N = 1 flux compactifications. In the first case, AM determines the stabilization of scalars at the black hole event horizon purely in terms of the electric and magnetic charges, whereas in the second...

Metastable Flux Configurations and de Sitter Spaces

We derive stability conditions for the critical points of the no-scale scalar potential governing the dynamics of the complex structure moduli and the axio-dilaton in compactifications of type IIB string theory on Calabi-Yau three-folds. We discuss a concrete example of a T 6 orientifold. We then consider the four-dimensional theory obtained from compactifications of type IIB string theory on n...

Nonrenormalization of Flux Superpotentials in String Theory

Recent progress in understanding modulus stabilization in string theory relies on the existence of a non-renormalization theorem for the 4D compactifications of Type IIB supergravity which preserve N = 1 supersymmetry. We provide a simple proof of this non-renormalization theorem using the known symmetries of these compactifications, thereby putting them on a similar footing as the betterknown ...

N = 2 Super - Higgs , N = 1 Poincaré Vacua and Quaternionic Geometry

In the context of N = 2 supergravity we explain the occurrence of partial super-Higgs with vanishing vacuum energy and moduli stabilization in a model suggested by superstring compactifications on type IIB orientifolds with 3-form fluxes. The gauging of axion symmetries of the quaternionic manifold, together with the use of degenerate symplectic sections for special geometry, are the essential ...
