Jet Physics in pp and PbPb Collisions with the CMS Experiment

The properties of dijets are reviewed for pp and PbPb collisions recorded by the CMS experiment. In particular, a dramatic quenching of jets is observed as a significant imbalance in the transverse momenta of dijets in central PbPb collisions at a center-of-mass energy of 2.76 TeV. The redistribution of the quenched jet energy is studied using the transverse momentum balance of charged tracks projected onto the direction of the leading jet. In contrast to pp collisions, a large fraction of the momentum balance for asymmetric jets is carried by low momentum particles at large angular distance to the jet axis.
