Abstract content

I will discuss the idea to combine singlet inflation and Higgs Portal Dark Matter in such a way that the same particle (a gauge singlet scalar) first drives inflation and later freezes out to become cold dark matter. Considering the implications of the Higgs discovery, limits from LUX and observations by Planck, I will show that large regions of parameter space remain viable but will be fully explored in the near future. Finally, I will comment on the stability of the electroweak vacuum and how to avoid the problem of unitarity-violation during inflation.
