Axion-driven spontaneous leptogenesis, precisely
Konstantin Kuckenberg, Martin A. Mojahed, Kai Schmitz +1
We revisit a minimal scenario for spontaneous leptogenesis where the asymmetry generation is driven by a heavy axion-like field evolving via standard misalignment. We focus on the…

A lower bound on the right-handed neutrino mass from wash-in leptogenesis
Martin A. Mojahed, Kai Schmitz, Dominik Wilken
Leptogenesis is an attractive scenario for the generation of the baryon asymmetry of the Universe that relies on the dynamics of right-handed neutrinos (RHNs) in the seesaw extensi…

Gravitational charge production
Martin A. Mojahed, Kai Schmitz, Xun-Jie Xu
Wash-in leptogenesis is an attractive mechanism to produce the baryon asymmetry of the Universe. It treats right-handed-neutrino interactions as spectator processes, on the same fo…
