摘要：
The polarization of a surrounding QCD medium modifies the induced gluon radiation spectrum of a high-energy parton at small transverse momenta for a single interaction and for multiple scatterings as well. This effect is an analogue of the Ter-Mikaelian effect in QED, superimposed to the Landau-Pomeranchuk effect. We study the Ter-Mikaelian effect in a phase space region where Abelian radiation does not occur. In this region the induced gluon radiation is shown to be suppressed due to polarization properties of the medium. (C) 2000 Published by Elsevier Science B.V. All rights reserved.
