  We present Monte-Carlo simulations of jet evolution in lead-lead collisions
at the Large Hadron Collider (LHC) at CERN focusing on the dijet asymmetry
measured by the ATLAS and CMS collaborations. In the simulation, hard partons
are interacting with the hydrodynamical background medium, undergoing radiative
and collisional processes. The measured dijet asymmetry is well described by
the simulation and is hence consistent with partonic energy loss in a hot,
strongly-interacting medium.
