Probing inelastic sub-GeV dark matter at the DUNE near detector
Amalia Betancur, Gustavo Castrillón, Óscar Zapata
We study inelastic dark matter (iDM) in a minimal and ultraviolet-complete framework in which the dark photon mass arises from a dark Higgs mechanism. The spontaneous breaking of a…

Inert doublet as multicomponent dark matter
Amalia Betancur, Guillermo Palacio, Andrés Rivera
In this work, we study multicomponent dark sectors comprised of a fermionic and a scalar dark matter candidate. In the scalar sector, we mostly focus on the Inert Doublet Model whi…

Phenomenology of doublet-triplet fermionic dark matter in nonstandard cosmology and multicomponent dark sectors
Amalia Betancur, Óscar Zapata
We consider the doublet-triplet fermionic model in the scheme of the custodial limit when the dark matter (DM) candidate is pure doublet and lies at the electroweak scale. This sch…
