Clockwork Inflation
Alex Kehagias, Antonio Riotto
We investigate the recently proposed clockwork mechanism delivering light degrees of freedom with suppressed interactions and show, with various examples, that it can be efficientl…
Scanning of the Supersymmetry Breaking Scale and the Gravitino Mass in Supergravity
Fotis Farakos, Alex Kehagias, Davide Racco +1
We consider the minimal three-form supergravity coupled to nilpotent three-form chiral superfields. The supersymmetry breaking is sourced by the three-forms of the chi…
Cosmology and Supergravity
S. Ferrara, A. Kehagias, A. Sagnotti
Abdus Salam was a true master of 20th Century Theoretical Physics. Not only was he a pioneer of the Standard Model (for which he shared the Nobel Prize with S. Glashow and S.Weinbe…
BMS in Cosmology
Alex Kehagias, Antonio Riotto
Symmetries play an interesting role in cosmology. They are useful in characterizing the cosmological perturbations generated during inflation and lead to consistency relations invo…
