Title: Simultaneous generation of visible and dark matter in the vanilla Scotogenic model

Abstract: We explore the possibility of generating both the visible and dark matter in the well motivated scotogenic neutrino mass model. The CP violating decay of a heavy Z_2 odd right handed neutrino (RHN) populates the visible sector through leptogenesis while simultaneously generating a multipartite dark sector. The relic abundance of dark matter is determined by the sub-GeV scale lightest RHN produced via freeze-in mechanism which is dynamically regulated by the interplay between the delayed decay and thermal scatterings of the next-to-lightest dark particle.
