Reopening the Z portal with semi-annihilations
María J. Domínguez, Oscar Rodríguez, Óscar Zapata
In one-component dark matter (DM) scenarios is commonly assumed that a scalar WIMP must either be part of an multiplet with zero hypercharge or have suppressed vector int…
A minimal model of fermion FIMP dark matter
Carlos E. Yaguna, Óscar Zapata
We investigate a simple extension of the standard model (SM) in which the dark matter consists of a feebly interacting fermion (FIMP), charged under a new symmetry, that is p…
One-loop Dirac neutrino mass and mixed axion/WIMP dark matter
Cristian D. R. Carvajal, Óscar Zapata
We consider the Peccei-Quinn (PQ) mechanism as the one behind the Dirac neutrino masses when these are generated through the effective operator at one…
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…
