Mach Cones in Heavy Ion Collisions — •Björn Bäuchle1,2,3, Laszlo P. Csernai2,4, and Horst Stöcker1,3,5 — 1ITP Frankfurt am Main — 2IFT Bergen — 3FIAS Frankfurt am Main — 4KFKI Budapest — 5GSI Darmstadt
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). An advantage of this approach is that the dynamics of the underlying medium is calculated from a (3+1)-dimensional hydrodynamical approach and the shapes of the mach cones are dynamically created by elementary waves emitted at constant time intervals. Hence, one avoids premature assumptions on the shape and evolution of these collective effects. Predictions for heavy-ion reactions at RHIC energies (Au+Au-collisions) and for Pb+Pb reactions at the LHC (√s=5.5A TeV) are presented and potential observations by the STAR, PHENIX and ALICE experiments are discussed.
