MACH CONES AND JET ENERGY LOSS STUDIES IN FULL (3+1)DIMENSIONAL IDEAL HYDRODYNAMICS

Abstract

A vigorous debate has recently concerned the quenching of jets by the expanding hot and dense medium created in high-energy nuclear collisions accompanied by Mach-cone-like structures at STAR and PHENIX.1,2 Large angle (w.r.t. the jet axis) peaks in the angular distribution of the particles created in the jet show up in both, 2- and 3-particle correlations. It is assumed that this reflects the interaction of the jet with the medium.3,4 However, the jet interactions with the medium are theoretically not understood well enough. Therefore, we present a first ideal (3+1)dimensional hydrodynamics approach with a sudden jet-energy deposition. Clearly, the hydrodynamical evolution strongly depends on the underlying equation of state (EoS) of the medium and therefore the influcence of the EoS on the evolution of the jet through the medium is of great interest for probing the EoS, the nature of the phase transition.
