Reheating the Standard Model from a hidden sector
Presented by Mr. Ville VASKONEN
Content
We consider a scenario where the inflaton decays to a hidden sector weakly coupled to the visible sector. Dark matter freezes out in the hidden sector and later a tiny portal coupling between the hidden and the visible sector heats the visible sector so that the Standard Model degrees of freedom dominate the energy density, before Big Bang Nucleosynthesis. We confront this scenario against different observational limits including dark matter abundance and primordial isocurvature perturbations and find that this scenario is viable though rather strictly constrained.
