Leptogenesis and rescattering in supersymmetric models
Lotfi Boubekeur, Sacha Davidson, Marco Peloso +1
The observed baryon asymmetry of the Universe can be due to the violating decay of heavy right handed (s)neutrinos. The amount of the asymmetry depends crucially on their num…
Cosmology of a brane radiating gravitons into the extra dimension
David Langlois, Lorenzo Sorbo, Maria Rodriguez-Martinez
We study in a self-consistent way the impact of the emission of bulk gravitons on the (homogeneous) cosmology of a three-brane embedded in a five-dimensional spacetime. In the low…
Moduli from Cosmic Strings
Marco Peloso, Lorenzo Sorbo
Moduli fields are generally present in superstring--inspired models. They are typically characterized by masses of the order of the supersymmetry breaking scale and by interactions…
Effective action for the homogeneous radion in brane cosmology
David Langlois, Lorenzo Sorbo
We consider cosmological two-brane models with AdS bulk, for which the radion, i.e. the separation between the two branes, is time dependent. In the case of two de Sitter branes (i…
