Jet Physics in Pb-Pb Collisions at the LHC with the ALICE Detector

In the high-multiplicity environment of central Pb--Pb collisions at the LHC
jet reconstruction is limited to energies above ~50 GeV with moderate
resolution ($\Delta E / E > 30\%$). Below this energies jets can only be
studied through inclusive particle correlations. However, as analysis of
data obtained at RHIC shows, it is likely that the most interesting
observables which can reveal the presence and nature of interactions of
final state partons with deconfinded partonic matter and the associated
radiation of additional gluons are mainly related to the structure of the
jets, i.e. the phase space distribution of particles close to the jet-axis.
Examples are the longitudinal and transverse momenta relative to the jet
axis.

The capabilities of ALICE to measure these distributions will be
demonstrated. The sensitivity for different quenching scenarios will be
discussed.
