Hubble-induced phase transitions in the Standard Model and beyond
Javier Rubio, Giorgio Laverda
We review the dynamics of spectator scalar fields non-minimally coupled to gravity in the post-inflationary Universe, with particular emphasis on scenarios where the end of inflati…
Higgs-Induced Gravitational Waves: the Interplay of Non-Minimal Couplings, Kination and Top Quark Mass
Giorgio Laverda, Javier Rubio
We explore a minimal scenario where the sole Standard-Model Higgs is responsible for reheating the Universe after inflation, produces a significant background of gravitational wave…
Phasing out of Darkness: From Sterile Neutrino Dark Matter to Neutrino Masses via Time-Dependent Mixing
Florian Goertz, Maya Hager, Giorgio Laverda +1
Sterile neutrinos are a compelling candidate for generating neutrino masses and for elucidating the nature of dark matter. Astrophysical X-ray constraints on sterile neutrino dark…
The Rise and Fall of the Standard-Model Higgs: Electroweak Vacuum Stability during Kination
Giorgio Laverda, Javier Rubio
In this paper we investigate the vacuum stability of the non-minimally coupled Standard-Model Higgs during a phase of kinetic domination following the end of inflation. The non-min…
