The authors' main claim We find that with a dimension-5 operator ${\partial_\mu Q} J_{B-L}^{\mu}$ suppressed by the Planck mass $M_{pl}$ or the Grand Unification Scale $M_{GUT}$, baryon number asymmetry $n_B/s \sim 10^{-10}$ can be naturally explained {\it via} leptogenesis.

We propose in this paper a scenario of spontaneous baryogenesis in cosmological models of Quintessence by introducing a derivative coupling of the Quintessence scalar $Q$ to the baryon current $J_B^{\mu}$ or the current of the baryon number minus lepton number $J_{B-L}^{\mu}$. We find that with a dimension-5 operator ${\partial_\mu Q} J_{B-L}^{\mu}$ suppressed by the Planck mass $M_{pl}$ or the Grand Unification Scale $M_{GUT}$, baryon number asymmetry $n_B/s \sim 10^{-10}$ can be naturally explained {\it via} leptogenesis. We study also the isocurvature baryon number fluctuation generated in our model.
