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…
Multicomponent scalar dark matter at high-intensity proton beam experiments
Amalia Betancur, Andrés Castillo, Guillermo Palacio +1
We study a scalar dark matter (DM) model with two DM species coupled to the Standard Model (SM) particles via a sub-GeV dark photon. In this model, we find that DM conversion occur…
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…
Measuring the mass, width, and couplings of semi-invisible resonances with the Matrix Element Method
Amalia Betancur, Dipsikha Debnath, James S. Gainer +2
We demonstrate the use of the Matrix Element Method (MEM) for the measurement of masses, widths, and couplings in the case of single or pair production of semi-invisibly decaying r…
Doublet-triplet dark matter with neutrino masses
Amalia Betancur, Robinson Longas, Oscar Zapata
We consider a dark matter (DM) model that arises from the interplay of two simplified dark matter models, namely the doublet-triplet fermion model and the doublet-triplet scalar mo…
