MACE -- Mach cones in heavy ion collisions

We study the propagation of sound-like perturbations created by a jet moving with supersonic velocity through the quark-gluon-plasma created in heavy-ion reactions within the model MACE (MAch Cone Evolution). Predictions for heavy-ion reactions at RHIC energies (Au+Au-collisions) and for Pb+Pb reactions at the LHC ($\sqrt{s}=5.5A$ TeV) are presented and potential observations by the STAR, PHENIX and ALICE experiments are discussed.
