Description
I will present fully relativistic calculations of dark matter bound state wave functions and cosmological rates that result from realistic models of dark matter. These bound states can have significant impact on early-universe cosmology, and significantly influence the dark matter relic density. Relativistic effects on the bound state wavefunctions give important corrections in regions where the cosmological impact of these bound states is of interest. The fully-relativistic technique also allows for the consideration of models which are ill-behaved in non-relativistic scattering, with the most notable example being pseudoscalar exchange between fermionic dark matter.
