Gravitational baryogenesis beyond the spectator approximation

David S. Pereira, Beatriz A. Fernandes, José Pedro Mimoso

The standard gravitational-baryogenesis operator $\lambda {\nabla }_{\mu }R{J}^{\mu }$, with $\lambda \equiv \epsilon /M_{\ast }^2$, is usually treated as a spectator interaction that generates an effective chemica…
