Standard Model Higgs Peaks: a Note on the Vacuum Instability during Inflation
G. Franciolini, A. Kehagias, A. Riotto
In the Standard Model, the Higgs potential develops an instability at high field values when the quartic self-coupling runs negative. Large quantum fluctuations during cosmic infla…
Superradiance Constraints from GW231123
Andrea Caputo, Gabriele Franciolini, Samuel J. Witte
Gravitational wave observations have recently revealed with high significance, and high precision, the existence of rapidly rotating black holes, allo…
Curvature Perturbations from First-Order Phase Transitions: Implications to Black Holes and Gravitational Waves
Gabriele Franciolini, Yann Gouttenoire, Ryusuke Jinno
Understanding whether primordial black holes form during strong first-order phase transition (FOPT) is a crucial open question in cosmology. We address this using a fully covariant…
Bubble Correlation in First-Order Phase Transitions
V. De Luca, G. Franciolini, A. Riotto
Making use of both the stochastic approach to the tunneling phenomenon and the threshold statistics, we offer a simple argument to show that critical bubbles may be correlated in f…
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…
