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…
Entanglement generation from gravitationally produced massless vector particles during inflation
Alessio Belfiglio, Mattia Dubbini, Orlando Luongo
We study the gravitational production of spectator massless vector particles in a single-field inflationary scenario, and the related entanglement generation across the Hubble hori…
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 scala…
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…
