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