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…
Non-Linear Supergravity and Inflationary Cosmology
Ignatios Antoniadis, Emilian Dudas, Fotis Farakos +1
We review a series of developments concerning non-linear realizations of supersymmetry coupled to supergravity, with emphasis on some applications to inflationary Cosmology.
Brane-Like Solutions and Other Non-Supersymmetric Vacua
J. Mourad, S. Raucci, A. Sagnotti
After recasting the standard charged and uncharged brane profiles in the harmonic gauge, we explore solutions with the same isometries where the potentials of te…
Brane Profiles of Non-Supersymmetric Strings
J. Mourad, S. Raucci, A. Sagnotti
We connect the indications of 2D CFT for branes in non-supersymmetric strings to actual spacetime profiles, taking the bulk tadpole potentials into account. We find exact solutions…
