The Ter-Mikayelian Effect on QCD Radiative Energy Loss

Nuclear Theory 2009-10-09 v3

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 both the longitudinal and transverse plasmon contributions to the zeroth order in opacity radiative energy loss. This QCD analog of the Ter-Mikayelian effect in QED leads to 30\sim 30% reduction of the energy loss of high transverse momentum charm quarks produced in a QCD plasma with a characteristic Debye mass μ0.5\mu\sim 0.5 GeV.
