Abstract

The color dielectric modification of the gluon dispersion relation in a dense QCD medium suppresses both the soft and collinear gluon radiation associated with jet production. We compute the longitudinal and transverse plasmon contributions to the zeroth order in opacity radiative energy loss in the one-loop hard thermal loop approximation. This is QCD analog of the Ter-Mikayelian effect in QED and leads to \ensuremath∼30% reduction of the energy loss of high transverse momentum charm quarks produced in a QCD plasma with a characteristic Debye mass \ensuremathμ\ensuremath∼0.5GeV.
