Abstract
We recently derived, using diagrammatic methods, the leading-order hard photon emission rate in ultra-relativistic plasmas. This requires a correct treatment of multiple scattering effects which limit the coherence length of emitted radiation (the Landau-Pomeranchuk-Migdal effect). In this paper, we provide a more physical derivation of this result, and extend the treatment to the case of gluon radiation.

29 pages, 18 figures. Corrected from version 1: missing factor of 1/k in final results and factor of 2 error on gg <-> g contribution to gluon production. (Also changed definition of N_s by a factor of 2.)
