AB  - If cosmic inflation was driven by an electrically neutral scalar field stable on cosmological time scales, the field necessarily constitutes all or part of dark matter (DM). We study this possibility in a scenario where the inflaton field s resides in a hidden sector, which is coupled to the Standard Model sector through the Higgs portal lambda(hs)s(2) (HH)-H-dagger and non-minimally to gravity via xi(s)s(2)R. We study scenarios where the field s first drives inflation, then reheats the Universe...
