Low scale seesaw, electron electric dipole moment, and leptogenesis in a model with spontaneousCPviolation

Strong correlations between leptogenesis and low energy $CP$ violating leptonic processes have been shown by us to exist in the minimal left-right symmetric model with spontaneous $CP$ violation. In this note, we investigate the implications of this model for the electric dipole moment of the electron. With an additional broken U(1)S symmetry, the seesaw scale can be lowered to close to the electroweak scale. This additional symmetry also makes the connection between $CP$ violation in quark sector to that in the lepton sector possible.
