摘要: The production rate for soft dileptons in a hot quark-gluon plasma is computed to leading order the QCD coupling constant through systematic resummation of perturbation theory. partial from annihilation and decay quarks antiquarks exhibits unexpected structure---sharp peaks due Van Hove singularities. These are overwhelmed by processes involving hard gluons. total larger than naive one-loop prediction orders magnitude.
