2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/139529We 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.6 pages, 6 figures, submitted to PRCNuclear Theorytext
