The observed matter-antimatter asymmetry in the Universe, the massive nature of neutrinos and the existence of dark matter are three firm observations that demonstrate the existence of new physics beyond the well established Standard Model of particle physics. It is remarkable that all these observations can be accounted for by a minimal extension of the Standard Model: the addition of right-handed neutrinos to its field content. I propose to conduct a very comprehensive analysis of this hypothesis, by performing a complete exploration of the viable parameter space and by evaluating the testability of the identified solutions in direct and indirect detection experiments, including high-intensity experiments, the LHC, the search for the Electric Dipole Moment of charged leptons and neutrinoless double-beta decay experiments. In addition, I will maintain and expand the capabilities of the MadbaM software - designed to perform automated computations of the Baryon Asymmetry of the Universe in general frameworks Beyond the Standard Model - in order to extend its applicability and improve its precision.

Abstract
The observed matter-antimatter asymmetry in the Universe, the massive nature of neutrinos and the existence of dark matter are three firm observations that demonstrate the existence of new physics beyond the well established Standard Model of particle physics. It is remarkable that all these observations can be accounted for by a minimal extension of the Standard Model: the addition of right-handed neutrinos to its field content. I propose to conduct a very comprehensive analysis of this hypothesis, by performing a complete exploration of the viable parameter space and by evaluating the testability of the identified solutions in direct and indirect detection experiments, including high-intensity experiments, the LHC, the search for the Electric Dipole Moment of charged leptons and neutrinoless double-beta decay experiments. In addition, I will maintain and expand the capabilities of the MadbaM software - designed to perform automated computations of the Baryon Asymmetry of the Universe in general frameworks Beyond the Standard Model - in order to extend its applicability and improve its precision.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
