Abstract
We study the collective flow of the QGP-fluid which transports the energy and momentum deposited from jets. Simulations of the propagation of jets together with expansion of the QGP-fluid are performed by solving relativistic hydrodynamic equations numerically in the fully (3+1)-dimensional space. Mach cones are induced by the energy-momentum deposition from jets and extended by the expansion of the QGP. As a result, low-pT particles are enhanced at large angles from the jet axis. This provedes an intimate link between the observables in di-jet asymmetric events in heavy-ion collisions and theoretical pictures of the medium excitation by jet-energy deposition.
