The presented jet shower-shape observables are angularity g and transverse momentum dispersion p(T)D, which were studied for a small resolution parameter R = 0.2, track-based jets with a minimum constituent transverse momentum (p(T)) cut-off of 0.15 GeV/c. Jet substructure is explored for track-based anti-k(T) jets with R = 0.4 by means of iterative declustering and grooming techniques, which were used to measure the absolutely-normalized leading subjet momentum fraction z(g) and the number of hard splittings in the reclustered jet shower, n(SD). These observables provide complementary information on the jet fragmentation and help to discriminate between different scenarios for medium-induced modifications of the parton shower in heavy-ion collisions due to jet quenching.
