In this talk we will discuss the interplay between radiative neutrino mass generation and minimal dark matter. We will discuss one-loop neutrino mass models in which one of the mediators is either a hypercharge-zero fermion quintet or a hypercharge-zero scalar septet. For these models we identified various processes that render the neutral component of the dark matter representation...

Accidental matter models are scenarios where the beyond-Standard-Model physics preserves the Standard Model accidental and approximate symmetries. Constraints from lepton-number-violating interactions, in particular those enforced by Majorana neutrino masses, fix the scale of the physics that can break these symmetries to 10^{15} GeV, and thus their effects are automatically suppressed. We...

The ANTARES neutrino telescope is searching for neutrinos produced in self-annihilation of Dark Matter (DM) particles. The analysis for different sources of DM (Sun, Galactic Center, Earth, …) and DM models (SUSY, Secluded) will be described and the results presented. The specific advantages of neutrino telescopes for this kind of searches will also be explained. For instance, the indirect...

Most of the MSSM DM scenarios (well-tempered neutralinos, funnels, co-annihilation) imply some kind of fine-tuning. We have studied this problem in an, as much as possible, exhaustive and rigorous way. I will present a brief discussion about the statistical meaning of the fine-tuning and how it should be computed for the DM abundance, and combined with the EW fine-tuning. Our results are very...

I will give an overview of the phenomenological aspects of a simplified dark matter scenario where the mediator is a new extra fermion (chiral or vector-like) carrying leptonic quantum number and the dark matter candidate is either scalar or vector. The extra lepton and the dark matter are odd under a Z^2 symmetry, hence the leptonic mediator can only interact with the dark matter state and...
