We analyze a simple extension of the Standard Model (SM)
with a dark sector composed of a scalar and a fermion, both singlets under the SM
gauge group but charged under a dark sector symmetry group, ${\rm G_{DM}}$.
The lightest of them is stable.
Sterile neutrinos, which are singlets under both groups, mediate
the interactions between the dark sector and the SM particles,
and ...

In this talk I will present a model in which large lepton flavour violation in the context of a type I seesaw model is generated. The model incorporates neutrino masses generation as well as a dark matter candidate among the sterile neutrino spectrum, the underlying leptonic symmetry rendering the latter naturally stable. We present a complete phenomenological study of the flavour...

The Scotogenic models provide a solution to neutrino physics and also to the Dark Matter problem. However, this appealing framework is not absent of problems, which can come from the mass of the Dark Matter candidate up to its stability. In this talk, the Scotogenic models will be introduced and some of the problems and possible solutions will be reviewed, with a special emphasis in the...

In this talk a version of the discrete dark matter mechanism will be presented where the breaking of the flavor symmetry is realized at the see-saw sacale in such a way that what remains of the flavor symmetry is a Z2 symmetry, which stabilizes the dark matter. The neutrino mass matrix has a two-zero texture form. We obtained a correlation between the lightest neutrino mass and the...

Electroweak scale right-handed neutrinos have become a commodity in recent years. Most scenarios involve the so-called sterile neutrino paradigm, where right-handed neutrinos are assumed to be completely neutral under the Standard Model gauge group. A more interesting possibility is - of course - one in which they do interact. Such a fertile (non-sterile) possibility is certainly important...
