Insights on the scale of leptogenesis from neutrino masses and neutrinoless double-beta decay

Abstract We revisit the thermal leptogenesis scenario in the type-I seesaw framework featuring three heavy Majorana neutrinos with a hierarchical mass spectrum. We focus on low energy observables, specifically the lightest neutrino mass $$m_{\nu }^{\textrm{lightest}}$$ m ν lightest and the neutrinol...
