Abstract
Because photons and leptons do not equilibrate in a short-lived quark-gluon plasma they provide important signals of the plasma. Radiative corrections to their propagators are quite different. The propagator for the photon (and other bosons) develops a thermal form which is correct to lowest order in the fine-structure constant but to all orders in the QCD coupling . By contrast, conservation of fermion number prevents the propagator for electrons, muons, or very heavy quarks from thermalizing at all.
