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…
Constraints on long-lived, higher-spin particles from galaxy bispectrum
Azadeh Moradinezhad Dizgah, Gabriele Franciolini, Alex Kehagias +1
The presence of massive particles with spin during inflation induces distinct signatures on correlation functions of primordial curvature fluctuations. In particular, the bispectru…
Primordial Black Holes from Inflation and Quantum Diffusion
Matteo Biagetti, Gabriele Franciolini, Alex Kehagias +1
Primordial black holes as dark matter may be generated in single-field models of inflation thanks to the enhancement at small scales of the comoving curvature perturbation. This me…
Detecting higher spin fields through statistical anisotropy in the CMB bispectrum
Gabriele Franciolini, Alex Kehagias, Antonio Riotto +1
Inflation may provide a suitable collider to probe physics at very high energies. In this paper we investigate the impact on the CMB bispectrum of higher spin fields which are long…
Primordial Black Holes from Inflation and non-Gaussianity
G. Franciolini, A. Kehagias, S. Matarrese +1
Primordial black holes may owe their origin to the small-scale enhancement of the comoving curvature perturbation generated during inflation. Their mass fraction at formation is ma…
