Abstract

Soft photon and gluon radiation off a fast quark propagating through nuclear matter is discussed. The close analogy between the Landau-Pomeranchuk-Migdal (LPM) effect in QED and the emission of soft gluons, suggested by Baier et al. [R. Baier, Yu.L. Dokshitzer, S. Peigne and D. Schiff, LPTHE-Orsay 94/98] for “hot” plasma, is confirmed and the relation between Mueller's approach and traditional calculations is established. It is shown that perturbative QCD can be applied to take into account the LPM coherent suppression both for photon and gluon induced radiation. The formulae for the photon and gluon radiation densities are presented.
