Description
Gluon bremsstrahlung is the dominant process through which high energy particles loose their energy in a Quark Gluon plasma. Calculations of the bremsstrahlung rate are complicated by interference between radiation from multiple collisions, giving rise to the Landau-Pomeranchuk-Migdal (LPM) effect. Previous authors have analysed the case where the coherence lengths of two consecutive emissions overlap, but in limits where at least one of the bremsstrahlung gluons is soft. We have gone beyond this approximation, treating general energies of bremsstrahlung gluons. We also show that the differential rate for double gluon bremsstrahlung can be reduced to a 1-dimensional integral which can be performed numerically.
