FIMP Dark Matter in Clockwork/Linear Dilaton Extra-Dimensions
Nicolás Bernal, Andrea Donini, Miguel G. Folgado +1
We study the possibility that Dark Matter (DM) is made of Feebly Interacting Massive Particles (FIMP) interacting just gravitationally with the Standard Model particles in the fram…
Gravitational dark matter production: primordial black holes and UV freeze-in
Nicolás Bernal, Óscar Zapata
Dark matter (DM) interacting only gravitationally with the standard model could have been produced in the early universe by Hawking evaporation of primordial black holes (PBH). Thi…
Self-interacting Dark Matter from Primordial Black Holes
Nicolás Bernal, Óscar Zapata
The evaporation of primordial black holes (PBH) with masses ranging from to g could have generated the whole observed dark matter (DM) relic density. It…
UV Freeze-in in Starobinsky Inflation
Nicolás Bernal, Javier Rubio, Hardi Veermäe
In the Starobinsky model of inflation, the observed dark matter abundance can be produced from the direct decay of the inflaton field only in a very narrow spectrum of close-to-con…
Boosting Freeze-in through Thermalization
Nicolás Bernal
If the interaction rates between the visible and the dark sectors were never strong enough, the observed dark matter relic abundance could have been produced in the early Universe…
Kaluza-Klein FIMP Dark Matter in Warped Extra-Dimensions
Nicolás Bernal, Andrea Donini, Miguel G. Folgado +1
We study for the first time the case in which Dark Matter (DM) is made of Feebly Interacting Massive Particles (FIMP) interacting just gravitationally with the standard model parti…
