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…
