A brief note on how to unify dark matter, dark energy, and inflation

Abstract

A scenario in which inflation, dark energy and dark matter can be unified into a single scalar field, the inflaton field $\varphi$, is studied. The inflaton is identified with the sneutrino, the scalar partner of the heavy neutrino. We determine the conditions needed for avoiding the gravitino problem and not having negligible plasma effects and we obtain the allowed range for the sneutrino coupling.
