On Cosmologies and Vacua Driven by Tension and Curvatures
J. Mourad, A. Sagnotti
We investigate the effects of the exponential potentials typical of non-supersymmetric strings in cosmologies whose spatial and internal slices are maximally symmetric spaces with…

Supersymmetry Breaking with Fields, Strings and Branes
E. Dudas, J. Mourad, A. Sagnotti
The first part of this review tries to provide a self-contained view of supersymmetry breaking from the bottom-up perspective. We thus describe N=1 supersymmetry in four dimensions…

On Pre-Inflationary non Gaussianities
M. Meo, A. Sagnotti
We explore the three-point amplitude of curvature perturbations in scenarios suggested by high-scale supersymmetry breaking in String Theory, where the inflaton is forced to climb…
