The cosmological relic densities of stable particles are calculated to high precision. The results depend on assumptions made about the quark-hadron phase transition. We discuss in detail the calculation of the thermally averaged annihilation cross section. We consider the specific cases of photinos, higgsinos, and Dirac and Majorana neutrinos.
