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…

Impact of a complex scalar spectator field on baryon asymmetry within spontaneous baryogenesis
Mattia Dubbini, Orlando Luongo, Marco Muccino
We extend the framework of spontaneous baryogenesis by investigating the generation of baryon asymmetry when the inflaton, , is minimally coupled with a complex spectator scalar…

Consequences of non-minimal coupling for mass mixing in spontaneous baryogenesis
Mattia Dubbini, Orlando Luongo, Marco Muccino
We investigate the impact of a non-minimal Yukawa-like coupling between curvature and inflaton field within the \emph{spontaneous baryogenesis} background. We demonstrate that this…
