An electroweak WIMP with TeV mass is a minimal and viable dark-matter candidate. Owing to the large dark-matter mass, the relevant electroweak interactions exhibit many features more familiar from the strong interaction. Predicting the dark-matter abundance and cosmic gamma-ray signal from dark-matter annihilation reliably requires understanding the electroweak static potential, resonant behaviour and unitarity violation, electroweak bound states, electroweak jets and Sudakov resummation, and possibly thermal effects in the plasma. In this seminar I discuss the diverse physical and field theoretical phenomena associated with TeV mass WIMPS approaching them with effective field theories and resummation methods familiar from QCD.
