The return of the WIMP: Onium in the Sky with Loops

An electroweak weakly interacting particle (WIMP) with TeV scale mass constitutes a minimalistic dark matter candidate. Extensive work in recent years has uncovered physical effects which -- despite the intrinsic weak interaction strength -- can dramatically change the signatures of dark matter annihilation. Owing to the large dark-matter mass, the relevant electroweak interactions exhibit many features more familiar from onium bound states and jets of the strong colour interaction. In this colloquium I discuss the diverse physical and field theoretical phenomena associated with TeV mass WIMPs approaching them with effective field theory and resummation methods better known from QCD.
