Distributions of relative transverse momentum difference between detector and particle level anti-$k_{\rm T}$ jets with $R=0.2$ (top) and $R=0.3$ (bottom) and several ranges of jet transverse momentum at particle level. The distributions correspond to the 10% most central events. Events were generated using PYTHIA with the standard ALICE detector response simulation using GEANT3 and the data reconstruction algorithms and settings used for Pb-Pb events. The dominant systematic uncertainty is the uncertainty on tracking efficiency.
