  Baryogenesis driven by curvature effects is investigated by taking into
account gravitationally induced particle production in the very early Universe.
In our scenario, the baryon asymmetry is generated dynamically during an
inflationary epoch powered by ultra-relativistic particles. The adiabatic
particle production rate provides both the needed negative pressure to
accelerate the radiation dominated Universe and a non-zero chemical potential
which distinguishes baryons and anti-baryons thereby producing a baryon
asymmetry in agreement with the observed value. Reciprocally, the present day
asymmetry may be used to determine the inflationary scale at early times.
Successful gravitational baryogenesis is dynamically generated for many
different choices of the relevant model parameters.
