Testable leptogenesis scenarios and phenomenological implications

The simplest extension of the Standard Model (SM) that can account for neutrinomasses consists in the addition of 2 right-handed neutrinos to the SM fieldcontent. In addition to the generation of the light neutrino mass and mixingpattern measured in neutrino oscillation experiments, the low scale realizationof the model provides an explanation for the matter-antimatter asymmetry of theUniverse via ARS leptogenesis, with right-handed neu-trino masses in the range[0.1-100] GeV. The heavy states can thus be produced and searched for inneutrinoless double beta decay searches, beam dump experiments, as SHiP or DUNE,and collider experiments as FCC-ee. We show that for O(GeV) scale right-handedneutrinos, future experimental data can provide sufficient information topredict the matter asymmetry of the universe. Furthermore, the flavor structureof this minimal model is extremely constrained and shows a very interestingcorrelation with the PMNS CP-phases which opens a new window to leptonic CPviolation.
