Box compactification and supersymmetry breaking

Soft Supersymmetry Breaking in KKLT Flux Compactification

We examine the structure of soft supersymmetry breaking terms in KKLT models of flux compactification with low energy supersymmetry. Moduli are stabilized by fluxes and nonperturbative dynamics while a de Sitter vacuum is obtained by adding supersymmetry breaking anti-branes. We discuss the characteristic pattern of mass scales in such a set-up as well as some features of 4D N = 1 supergravity ...

Dynamical Compactification as a Mechanism of Spontaneous Supersymmetry Breaking

Supersymmetry breaking and compactification of extra space-time dimensions may have a common dynamical origin if our Universe is spontaneously generated in the form of a four-dimensional topological or non-topological defect in higherdimensional space-time. Within such an approach the conventional particles are zero modes trapped in the core of the defect. In many cases solutions of this type s...

Soft Masses in Theories with Supersymmetry Breaking by TeV - Compactification

Duality versus supersymmetry and compactification.

We study the interplay between T-duality, compactification and supersymmetry. We prove that when the original configuration has unbroken space-time supersymmetries, the dual configuration also does if a special condition is met: the Killing spinors of the original configuration have to be independent on the coordinate which corresponds to the isometry direction of the bosonic fields used for du...

Inflation and Supersymmetry Breaking

We study the connection between inflation and supersymmetry breaking in the context of an O’Raifeartaigh model which can account for both hybrid inflation and a true vacuum where supersymmetry is spontaneously broken. For a weakly coupled inflaton field, the dynamics during the inflationary phase can be determined by the supersymmetry breaking scale MS ∼ 1010 GeV, even if HI ≫ m3/2. The spectru...
