Zusammenfassung

A formalism for the evaluation of the intensity of photon and gluon bremsstrahlung in QED and QCD condensed media is presented which considers general interactions beyond the Fokker-Planck approximation, the angular distribution of the final particles and admits finite or structured target calculations. The Fokker-Planck results of Migdal/Zakharov and the BDMPS group are recovered under the adequate approximations as particular cases. Weinberg's soft photon theorem is shown to saturate the LPM supression in the soft regime. The angle integrated intensity under realistic screened interactions is always larger than the Fokker-Planck evaluation and the changes can not be accounted for by a single definition of the medium transport properties.
