Investigation of relativistic shock waves and Mach cones in a partonic cascade
- In this work the main emphasis is put on the investigation of relativistic shock waves and Mach cones in hot and dense matter using the microscopic transport model BAMPS, based on the relativistic Boltzmann equation. Using this kinetic approach we study the complete transition from ideal-fluid behavior to free streaming. This includes shock-wave formation in a simplified (1+1)-dimensional setup as well as the investigation of Mach-cone formation induced by supersonic projectiles and/or jets in (2+1)- and (3+1)-dimensional static and expanding systems. We further address the question whether jet-medium interactions inducing Mach cones can contribute to a double-peak structure observed in two-particle correlations in heavy-ion collision experiments. Furthermore, BAMPS is used as a benchmark to compare kinetic theory to several relativistic hydrodynamic theories in order to verify their accuracy and to find their limitations.
