Jet Propagation and Mach Cones in
Heavy-Ion Collisions

Jets are a useful probe in understanding the high energy density matter created in nuclear collisions. These partons deposit energy and momentum by interacting with the surrounding medium before final state hadrons are formed. Particle correlations measured at the Relativistic Heavy Ion Collider (RHIC) show a conical shape which could be traced back to the creation of a Mach cone due to the propagation of a supersonic parton. Recently, much attention has been given to understanding the medium's response to the propagation of a supersonic jet in the sQGP. I'll report on this new developments and present results for different jet energy loss mechanisms computed within (3+1)dimensional ideal hydrodynamics.
