Charged jet production cross sections in p–Pb collisions at measured with the ALICE detector at the LHC are presented. Using the anti-kT algorithm, jets have been reconstructed in the central rapidity region from charged particles with resolution parameters R=0.2 and 712ba53204ae700960f35bc6ce5fcf2d" title="Click to view the MathML source">R=0.4. The reconstructed jets have been corrected for detector effects and the underlying event background.

Major modifications to the radial jet structure are probed via the ratio of jet production cross sections reconstructed with the two different resolution parameters. This ratio is found to be similar to the measurement in pp collisions at and to the expectations from PYTHIA pp simulations and NLO pQCD calculations at .
