Quantum Seesaw Cosmology: A Heating Phase from Pauli Blocking
Nicolás Bernal, Chee Sheng Fong
In Seesaw Cosmology, a scalar field reheats the Standard Model (SM) through right-handed neutrinos (RHNs), which generate tiny neutrino masses through the seesaw mechanism. When RH…
Seesaw Cosmology
Nicolás Bernal, Chee Sheng Fong, Óscar Zapata
We study perturbative reheating in which the inflaton transfers its energy to the Standard Model through right-handed neutrinos (RHNs) responsible for light-neutrino masses via the…
Reheating the FCC: Probing Early Matter Domination with Long-Lived Particles
Nicolás Bernal, Giovanna Cottin, Kuldeep Deka +1
We study a GeV-scale Higgs-portal scalar that can dominate the early Universe and later decay into Standard Model states, ending an early matter-dominated era. Ordinary cosmic…
Minimal Freeze-in Dark Matter: Reviving electroweak doublet dark matter with Boltzmann suppressed freeze-in
Nicolás Bernal, Sagnik Mukherjee, James Unwin
Dark matter communicating with the Standard Model solely via electroweak interactions provides a compelling picture. However, thermal freeze-out of electroweak doublet dark matter…
