    abstract = "The ALICE collaboration at the CERN LHC reports novel measurements of
jet substructure in pp collisions at root s = 7 TeV and central Pb-Pb
collisions at root s(NN) = 2.76 TeV. Jet substructure of track-based
jets is explored via iterative declustering and grooming techniques. We
present the measurement of the momentum sharing of two-prong
substructure exposed via grooming, the z(g), and its dependence on the
opening angle, in both pp and Pb-Pb collisions. We also present the
measurement of the distribution of the number of branches obtained in
the iterative declustering of the jet, which is interpreted as the
number of its hard splittings. In Pb-Pb collisions, we observe a
suppression of symmetric splittings at large opening angles and an
enhancement of splittings at small opening angles relative to pp
collisions, with no significant modification of the number of
splittings. The results are compared to predictions from various Monte
Carlo event generators to test the role of important concepts in the
evolution of the jet in the medium such as colour coherence. (C) 2020
