Abstract：
Quintessence is a possible candidate for dark energy. In this paper we study the possibility of Quintessence interacting with the ordinary matter and its implications in baryogenesis. With a specific coupling of the Quintessence to the baryon fields, we will show that the baryon number asymmetry of the universe can be explained naturally. We will also in this paper study the isocur-vature perturbation of the baryon number in our model.
