Exploring jet substructure with jet shapes in ALICE
Abstract
The characterization of the jet substructure can give insight into the microscopic nature of the modification induced on high-momentum partons by the Quark-Gluon Plasma that is formed in ultra-relativistic heavy-ion collisions. Jet shapes allow us to study the modification of parton to jet fragmentation and virtuality, probing jet energy redistribution, intra-jet broadening or collimation and possible flavour hierarchy. Results of a selected set of jet shapes will be presented for p--Pb collisions at s NN= 5.02~TeV and for Pb--Pb collisions at s NN = 2.76~TeV. Results are also compared with PYTHIA calculations and models that include in-medium energy loss.
