• Impact of spectator fields and non-minimal couplings in spontaneous baryogenesis (2026) · International Journal of Modern Physics A · doi

  In this work, we extended the model of spontaneous baryogenesis considering two different scenarios. Firstly, we introduced a non-minimal coupling term between gravity and the inflaton. We showed that this term significantly enhances baryogen- esis, and accordingly the model can reproduce the experimental value of the baryon asymmetry. Then, we considered a complex scalar spectator field non-minimally coupled to gravity and through a biquadratic interaction to the inflaton. Also in this case, we obtained a remarkable improvement in terms of baryon asymmetry, but not sufficient to reproduce cosmological observations. Future works comprehend further extensions of the spontaneous baryogenesis framework, such as including the electromagnetic sector through a coupling with the inflaton. Another intriguing possibility is the introduction of a disformal non- minimal coupling between inflaton and gravity, as a generalization of the conformal one studied in this work. It would also be worthwhile to replace the complex scalar spectator field with a fermion, to evaluate its impact on baryogenesis. Lastly, a more realistic treatment of spontaneous baryogenesis would incorporate quantum chromodynamics, possibly unveiling new mechanisms of asymmetry generation.
