We describe a possible scenario for spontaneous baryogenesis given by the Randall–Sundrum brane-world model with two branes and a radion stabilizing potential. It is known that the cosmological expansion of the Universe can be recovered in this brane-world model by adding matter on the branes, and time-reversal is then broken. We show here that, as a consequence of such a time dependence of the system, the effective coupling of the radion with matter fields generates a chemical potential with opposite signs for baryons and anti-baryons and spontaneous baryogenesis is therefore induced naturally and self-consistently.
