"[I]t is quite fascinating that two seemingly unrelated problems—the tiny masses of light neutrino and the matter-antimatter asymmetry—may be explained by the mere introduction of heavy RH [right-hand] neutrinos to the SM. ...[T]he former may be explained by the Type I seesaw mechanism while thermal leptogenesis provides an attractive solution to the later. This... means that an intricate link between neutrino properties and the baryon asymmetry can be established. Consequently, it has been the purpose of this work to explore the implications of several different neutrino models in the leptogenesis context."
