Jets are an important tool to probe the medium produced in ultra-relativistic heavy ion collisions. In PbPb collisions a significant energy loss (jet quenching) of the partons traversing the hot and dense medium has been observed and quantified through a variety of measurements: dijet momentum imbalance, photon-jet correlations, measurements of the fragmentation pattern and the jet shapes, charged hadron nuclear modification factors. It is expected that in pPb collisions the hot medium is not produced. It is important to study the effect of the cold nuclear medium on the hard-scattering probes. The first CMS measurements of jets in pPb collisions will be presented.
