Implications of the detection of primordial gravitational waves for the Standard Model
G. Franciolini, G. F. Giudice, D. Racco +1
The detection of primordial gravitational waves would not only have extraordinary implications for our understanding of early cosmology, but would also give non-trivial constraints…
Testing Primordial Black Holes as Dark Matter through LISA
N. Bartolo, V. De Luca, G. Franciolini +3
The idea that primordial black holes (PBHs) can comprise most of the dark matter of the universe has recently reacquired a lot of momentum. Observational constraints, however, rule…
The Primordial Black Hole Dark Matter - LISA Serendipity
N. Bartolo, V. De Luca, G. Franciolini +3
There has recently been renewed interest in the possibility that the dark matter in the universe consists of primordial black holes (PBHs). Current observational constraints leave…
A note on Inflation and the Swampland
Alex Kehagias, Antonio Riotto
We provide some comments about the constraints on the inflationary models inferred from the two Swampland criteria which have been recently proposed. In particular we argue that, i…
The Spatial Clustering of Primordial Black Holes
Vincent Desjacques, Antonio Riotto
The possibility that primordial black holes (PBHs) are the dark matter (or a fraction thereof) has attracted much attention recently. Their spatial clustering is a fundamental prop…
Liberated N=1 Supergravity
Fotis Farakos, Alex Kehagias, Antonio Riotto
We discuss a new interaction for chiral models in four-dimensional supergavity. It contains a new arbitrary function in addition to the Kähler potential and superpoten…
