Description
See above
Summary
I will present constraints on simplified 'portal' models of dark matter due to demanding perturbative unitarity of all scatterings. This gives an upper bound for the dark matter mass given a standard thermal history of the universe. I will also discuss the contribution of non-perturbative phenomena, particularly bound state formation and subsequent decays to standard model particles, to the freezeout process.
