Abstract We discuss how a post-inflationary reheating phase characterized by a nonstandard multiple scalar field cosmology can change the thermal history of the Universe, affecting minimal high-scale leptogenesis. In particular, we explore a class of models where a set of scalar fields in a brane-inspired dynamical scenario modifies the Boltzmann equations concerning standard leptogenesis.
