Abstract

A framework for baryogenesis where CP violation lies in a gravitational interaction was presented. It was found that the expansion of the Universe promotes the microscopic CP violation to a dynamical violation of CPT that shifts the relative energies of particles and antiparticles. It was also found that the CP-conserving B-violating interaction in equilibrium create the asymmetry when the B-violating interaction decouples. The results show that a gravitational interaction between the derivative of the Ricci scalar curvature and the baryon-number current dynamically breaks CPT in expanding universe.
