-Mediated Dark Matter with Low-Temperature Reheating
Geneviève Bélanger, Nicolás Bernal, Alexander Pukhov
We consider a simple extension of the standard model with fermionic dark matter (DM) and a gauge boson acting as a mediator. We also assume a scenario where cosmic reheating o…
Heavy Neutral Leptons without Prejudice
Nicolás Bernal, Kuldeep Deka, Marta Losada
Heavy Neutral Leptons (HNLs) provide a compelling extension to the Standard Model, addressing the neutrino masses, baryogenesis, and dark matter problems. We perform a model-indepe…
From WIMPs to FIMPs: Impact of Early Matter Domination
Javier Silva-Malpartida, Nicolás Bernal, Joel Jones-Pérez +1
In the context of non-standard cosmologies, an early matter-dominated (EMD) era can significantly alter the conventional dark matter (DM) genesis. In this work, we reexamine the im…
Thermal Dark Matter with Low-Temperature Reheating
Nicolás Bernal, Kuldeep Deka, Marta Losada
We explore the production of thermal dark matter (DM) candidates (WIMPs, SIMPs, ELDERs and Cannibals) during cosmic reheating. Assuming a general parametrization for the scaling of…
