We provide the first systematic study of the low-scale leptogenesis scenario in the minimal Standard Model extended with 3 right-handed neutrinos having masses at the GeV scale. We highlight and discuss the differences between the 2- and the 3-right-handed neutrino cases, the major qualitative distinction being the possibility, in the latter scenario, of probing part of the parameter space at...

This talk is based on [arXiv:1806.06864][1].
We will present an extension of the Standard Model, including three right-handed neutrinos $N_i$ and a new Higgs doublet $\Sigma$, all charged under a exact $Z_2$ parity symmetry. This framework is also known as the "Scotogenic model".
We will discuss how one can realize the SM neutrino masses + mixing angles and also generate the observed DM...

The simplest extension of the SM that can account for neutrino masses consists in the addition of 2 right-handed neutrinos to the SM field content.
In addition to the generation of the light neutrino mass and mixing pattern measured in neutrino oscillations, the low scale realization of the model
provides an explanation for the matter-antimatter asymmetry of the Universe via ARS...

Constraining thermal DM above 100 TeV using Indirect Detection experiments is generally accepted to be either irrelevant or technically challenging. Irrelevant, because the unitarity of the S-matrix implies an upper bound on the thermal DM mass of order 100 TeV. Technically challenging, because the electroweak radiative corrections become non-perturbative above 100 TeV. We consider the class...
