Low scale leptogenesis with an SU(2)_L singlet scalar
Michele Frigerio
We consider thermal leptogenesis as the origin of the matter-antimatter asymmetry of the Universe. Some phenomenologically unpleasant features of the usual leptogenesis scenario ar…

Interplay of type I and type II seesaw contributions to neutrino mass
Evgeny Kh. Akhmedov, Michele Frigerio
Type I and type II seesaw contributions to the mass matrix of light neutrinos are inherently related if left-right symmetry is realized at high energy scales. We investigate implic…

Right-Handed Sector Leptogenesis
Michele Frigerio, Thomas Hambye, Ernest Ma
Instead of creating the observed baryon asymmetry of the universe by the decay of right-handed (RH) neutrinos to left-handed leptons, we propose to generate it dominantly by the de…
