Guy Moore University of Washington The rate of hard photon emission from the Quark Gluon Plasma (at temperatures where the coupling gs is weak) involves, at leading order, inelastic processes such as bremsstrauhlung, with hard but collinear outgoing states. These processes get order one corrections due to interference between successive scatterings, which is known as the Landau-Pomeranchuk-Migdal (LPM) effect. I show how to compute the photon emission rate, treating this effect in a complete way, and present leading order (in gs) results for hard photon emission from the quark-gluon plasma.
