How heavy can the Fermions in Split Susy be? A study on Gravitino and Extradimensional LSP
Leonardo Senatore
In recently introduced Split Susy theories, in which the scale of Susy breaking is very high, the requirement that the relic abundance of the Lightest SuperPartner (LSP) provides t…

Isocurvature constraints on gravitationally produced superheavy dark matter
Daniel J. H. Chung, Edward W. Kolb, Antonio Riotto +1
We show that the isocurvature perturbations imply that the gravitationally produced superheavy dark matter must have masses larger than few times the Hubble expansion rate at the e…

Tilted Ghost Inflation
Leonardo Senatore
In a ghost inflationary scenario, we study the observational consequences of a tilt in the potential of the ghost condensate. We show how the presence of a tilt tends to make conta…
