“…[5] such peaks were predicted as a signature of Mach shocks created by partonic jets propagating through a quark-gluon plasma (QGP) formed in a heavy-ion collision. Analogous Mach shock waves were studied previously in a cold hadronic matter [6,7,8,9,10] as well as in nuclear Fermi liquids [11,12]. The Machshock induced electron emission from metal surfaces have been predicted [13] and then observed experimentally in Ref.…”

We study Mach shocks generated by fast partonic jets propagating through a deconfined strongly-interacting matter. Our main goal is to take into account different types of collective motion during the formation and evolution of this matter. We predict a significant deformation of Mach shocks in central Au+Au collisions at RHIC and LHC energies as compared to the case of jet propagation in a static medium. The observed broadening of the near-side two-particle correlations in pseudorapidity space is explained by the Bjorken-like longitudinal expansion.Three-particle correlation measurements are proposed for a more detailed study of the Mach shock waves.

“…Thus, at the microscopic level, the cone of particles should be produced. Now, everything depends on how one treats the hadronic medium [33,34,35,36,37,38,39,40,41,42] and whether sound waves can propagate in it. Unfortunately, our knowledge of this medium is still not complete enough to answer these questions.…”

“…Intranuclear cascade calculations are based on the assumption that a nuclear collision is equivalent to the superposition of nucleon-nucleon collisions. Hydrodynamical models on the other hand predicted the appearance of shock waves initiated by a very high energy incident particle early on [1] and other authors also considered shock waves in colliding nuclei [2,3]. But a mechanism of shock compression in nucleus-nucleus collisions that would lead to densities 3 to 5 times higher than that of normal nuclear matter was first proposed by Scheid et a/.…”
