Abstract
QCD corrections to fermionic Minimal Dark Matter annihilations increase its annihilation cross section (by 2% for a weak doublet, 1.3% for a triplet, 0.5% for a quintuplet) and thereby the Dark Matter mass required to achieve the observed cosmological relic abundance via thermal freeze-out.
