Photon emission from quark-gluon plasma: complete leading order results

Wecomputethephotonemissionrateofanequilibrated,hotQCDplasmaat zero chemical potential, to leading order in both fiEM and the QCD coupling gs(T). This requires inclusion of near-collinear bremsstrahlung and inelastic pair annihilation contri- butions, andcorrect incorporation of Landau-Pomeranchuk-Migdal suppressionefiects for these processes. Analogous resultsfor aQED plasmaare also included.
