Description:
Author(s): Matthias Le Dall and Adam Ritz We study the impact on leptogenesis of Higgs portal couplings to a new scalar singlet. These couplings open up additional CP-violating decay channels for the higher mass singlet neutrinos N2 and N3. We analyze the simplest case of two-level N1-N2 leptogenesis, including significant mass hierarchies,... [Phys. Rev. D 90, 096002] Published Wed Nov 12, 2014
