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 $\mbox{p--Pb}$ collisions at $\sqrt{s_{\mathrm{NN}}}=5.02\mathrm{TeV}$ and for $\mbox{Pb--Pb}$ collisions at $\sqrt{s_{\mathrm{NN}}}=2.76\mathrm{TeV}$. Results are also compared with PYTHIA calculations and models that include in-medium energy loss.
