The Ter-Mikaelian and Landau-Pomeranchuk effects for induced soft gluon radiation in a QCD medium

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,
however it appears in QCD in a different phase space region.
