    • note
    • See also [14] for another baryogenesis model which makes use of Dirac neutrinos. However, in that work, the scalar fields decay into right-handed neutrinos and left-handed leptons, instead of inducing Dirac mass terms as they do in our work. In terms of using time-dependent fermion mass terms, our scenario has analogies with "coherent baryogenesis" [15].

    • In models that obtain small Dirac couplings by the Frogatt-Nielsen [19] technique, our rolling scalar could be the singlet inflaton field.

    • note
    • Note that the phase of θ cannot be rotated away without introducing CP-violating phases in the interaction Lagrangian. As discussed in [17], having a nonvanishing initial phase of θ after inflation is completely natural.
