Relic density of dark matter in the inert doublet model beyond leading order for the low mass region. IV. The Higgs resonance region

One-loop electroweak corrections to the annihilation cross-sections of dark matter in Higgs resonance region inert doublet model (IDM) are investigated. The procedure how implement width order regularise amplitude both at tree-level and one-loop together with renormalisation a key parameter model, thoroughly scrutinised. discussions go beyond application relic density calculation also IDM so that addressing these technical issues can help wider context. We look particular dominant channels $b \bar b$ final state more involved 3-body state, $W f f^\prime$, where an anti-resonance, due interference effects, present. discuss integrate over such configurations when converting into density.
