  • We revisit leptogenesis in the minimal non-supersymmetric type I see-saw mechanism with two right-handed (RH) neutrinos, including flavour effects and allowing both RH neutrinos N1 and N2 to contribute, rather than just the lightest RH neutrino N1 that has hitherto been considered. By performing scans over parameter space in terms of the single complex angle z of the orthogonal matrix R, for a range of PMNS parameters, we find that in regions around z ∼ ±�/2, for the case of a normal mass… CONTINUE READING
