Baryon Asymmetry, DM and Neutrino Masses

We will discuss a relatively minimal model for neutrino masses with only two heavy Right Handed neutrinos that can also produce an asymmetric Dark Matter(DM) component, at the same time as the baryon asymmetry of the Universe. The necessary sources for CP violation are in both sectors the complex ne...

description We will discuss a relatively minimal model for neutrino masses with only two heavy Right Handed neutrinos that can also produce an asymmetric Dark Matter(DM) component, at the same time as the baryon asymmetry of the Universe. The necessary sources for CP violation are in both sectors the complex neutrino Yukawa couplings, which can be even chosen purely real and imaginary for each of the RH neutrinos in order to reduce the number of parameters. Then the CP symmetries in both DM and leptons are naturally of the same order and the correct DM density is obtained for a DM mass in the GeV range. We predict in this model a possible signal in DM direct detection via exchange of the SM Higgs and the additional Higgs in the Dark sector and the neutrinoless double-beta decay effective mass in the range 1,5 − 3,7 meV.
