We apply a formalism accounting for thermal effects (such as modified Sommer- feld effect; Salpeter correction; decohering scatterings; dissociation of bound states), to one of the simplest WIMP-like dark matter models, associated with an “inert” Higgs doublet. A broad temperature range T ~ M/20...M/10⁴ is considered, stressing the importance and less-understood nature of late annihilation stages. Even though only weak interac- tions play a role, we find that resummed real and virtual corrections increase the tree-level overclosure bound by 1 . . . 18%, depending on quartic couplings and mass splittings.
