Abstract
We discuss the energy loss of a colored particle (∼ a leading particle of jets) and a color dipole (∼ heavy quarkonia) passing through a quark-gluon plasma (QGP) taking into account the dynamic screening effect, in the framework of the semiclassical kinetic theory. We also show how the energy supplied by these test charges is distributed in the QGP, which gives us further physical insight about the energy-loss mechanism and the plasma response to such external probes.
