Gravitational baryogenesis beyond the spectator approximation

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

The standard gravitational-baryogenesis operator $\hat{I}»{\nabla }_{\hat{I}}¼R{J}^{\hat{I}}¼$, with $\hat{I}»\equiv \hat{I}\mu /M_{\ast }^2$, is usually treated as a spectator interaction that generates an effective ch…
