Abstract: The minimal requirements for every inflationary model are that the inflaton field gives a long enough period of exponential expansion and subsequently reheats the universe, so that thermal equilibrium is attained prior to Big Bang Nucleosynthesis. But could the inflaton be responsible for something else as well, namely the generation of dark matter or the electroweak phase transition? As a representative model example, we study these aspects in a scenario where the inflaton is a real singlet scalar. Requiring the model to describe inflation successfully, be compatible with the LHC data, and yield a) the correct dark matter abundance or b) a strong first order electroweak phase transition, we identify the regions of the parameter space where the model is viable.
