Boltzmann Suppressed Ultraviolet Freeze-in
Nicolás Bernal, Sagnik Mukherjee, James Unwin
If the dark matter mass exceeds the maximum temperature of the Universe (), then its production rate will be Boltzmann suppressed. The important implications o…
Testing frozen-in pNGB dark matter with a long-lived dark Higgs
Nicolás Bernal, Giovanna Cottin, Bastián Díaz Sáez +1
We consider a simple Higgs portal dark matter (DM) model, where the Standard Model is extended with a complex singlet scalar. The imaginary part of the scalar becomes a massive and…
Enabling Thermal Dark Matter within the Vanilla - Model
Nicolás Bernal, Jacinto P. Neto, Javier Silva-Malpartida +1
Thermal dark matter is a compelling setup that has been probed by a multitude of experiments, mostly in the GeV-TeV mass range. The thermal paradigm in the sub-GeV range is about t…
Freezing-in Cannibals with Low-reheating Temperature
Nicolás Bernal, Esau Cervantes, Kuldeep Deka +1
The freeze-in mechanism provides a compelling framework for dark matter (DM) production, particularly suited to scenarios involving feeble interactions with the Standard Model (SM)…
Constraining the Coexistence of Freeze-in Dark Matter and Primordial Black Holes
Prolay Chanda, Sagnik Mukherjee, James Unwin
Particle dark matter and primordial black holes (PBH) might coexist with appreciable cosmic abundances, with both contributing to the observed dark matter density . Lar…
Probing low-reheating scenarios with minimal freeze-in dark matter
Nicolás Bernal, Chee Sheng Fong, Óscar Zapata
The parameter space of freeze-in dark matter (DM) with mass through light dark photon (``minimal freeze-in DM'') is currently being probed by direct detection experiments thr…
Dark Matter Ultraviolet Freeze-in in General Reheating Scenarios
Nicolás Bernal, Kuldeep Deka, Marta Losada
The dynamics of cosmic reheating, that is, on how the energy stored in the inflaton is transferred to the standard model (SM) thermal bath, is largely unknown. In this work, we sho…
