  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, a large fraction of the
transverse momentum deposited from jets is compensated by low-$p_{T}$ particles
at large angles from the jet axis. This result is consistent with the data from
the {CMS} Collaboration and gives a novel interpretation of them.
