Impact of spectator fields and non-minimal couplings in spontaneous baryogenesis
Mattia Dubbini
We investigate the model of spontaneous baryogenesis, considering two extensions to the background paradigm. Firstly, we introduce a non-minimal coupling between gravity and the in…

Vector-field spontaneous baryogenesis with Lorentz invariance violation
Mattia Dubbini, Orlando Luongo, Aniello Quaranta
We extend spontaneous baryogenesis by considering the spontaneous breaking of through a complex vector field. This field interacts with baryons and leptons via a vector-cu…
