  We discuss the potential information about highly excited QCD-matter provided
by medium-induced partonic energy loss, known as ``jet quenching''. In
particular, with its large acceptance hadronic and electromagnetic calorimetry,
the Compact Muon Solenoid detector at LHC collider is a promising device to
study these effects. We present physics simulations of observables such as the
jet distribution with impact parameter, the azimuthal anisotropy of jet
quenching, and the effects of b-quark energy loss on the high-mass dimuon
continuum and secondary charmonium production.
