Flux Compactification

  title={Flux Compactification},
  author={Michael R. Douglas and Shamit Kachru},
We review recent work in which compactifications of string and M theory are constructed in which all scalar fields (moduli) are massive, and supersymmetry is broken with a small positive cosmological constant, features needed to reproduce real world physics. We explain how this work implies that there is a “landscape” of string/M theory vacua, perhaps containing many candidates for describing real world physics, and present the arguments for and against this idea. We discuss statistical surveys…

Scanning the landscape of flux compactifications: vacuum structure and soft supersymmetry breaking
We scan the landscape of flux compactifications for the Calabi-Yau manifold 4[1,1,1,6,9] with two Kahler moduli by varying the value of the flux superpotential W0 over a large range of values. We do
Compactified string theories — Generic predictions for particle physics
In recent years it has been realized that in string/M theories compactified to four dimensions which satisfy cosmological constraints, it is possible to make some generic predictions for particle
String Theory, Dark Energy and Varying Couplings
I review the difficulties of some recent attempts to find stabilized string theory vacua with positive cosmological constant at tree level. Whereas models with energy momentum tensors satisfying the
Explaining the Electroweak Scale and Stabilizing Moduli in M Theory
In a recent paper [1] it was shown that in M theory vacua without fluxes, all moduli are stabilized by the effective potential and a stable hierarchy is generated, consistent with standard gauge
Runaway in the Landscape
We consider flux compactifications of type IIB string theory on the mirror of a rigid Calabi-Yau. In special cases, these models are dual to the type IIA flux vacua with runaway direction in flux
The Higgs Field and Early Universe Cosmology: A (Brief) Review
We review and discuss recent work exploring the implications of the Higgs field for early universe cosmology, and vice versa. Depending on the model under consideration, the Higgs may be one of a few
Massive IIA flux compactifications and U-dualities
We attempt to find a rigorous formulation for the massive type IIA orientifold compactifications of string theory introduced in [1]. An approximate double T-duality converts this background into IIA
String loop moduli stabilisation and cosmology in IIB flux compactifications
We present a detailed review of the moduli stabilisation mechanism and possible cosmological implications of the LARGE Volume Scenario (LVS) that emerges naturally in the context of type IIB
Aspects of Moduli Stabilization in Type IIB String Theory
We review moduli stabilization in type IIB string theory compactification with fluxes. We focus on KKLT and Large Volume Scenario (LVS). We show that the predicted soft SUSY breaking terms in KKLT
