(Left) Distribution of jet angularity for $R=0.2$ charged-particle jets in 0--10\% central \PbPb\ collisions compared to that for \pp\ collisions calculated with the PYTHIA6 event generator . (Right) Jet mass for $R=0.4$ charged-particle jets in 0--10\% central compared to PYTHIA calculations and various jet quenching models  Systematic uncertainties have not been assigned to the PYTHIA calculations in both panels.
