Exploring jet substructure with jet shapes in ALICE

The characterisation 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. This modification of parton-to-jet fragmentation and of the parton virtu...

description The characterisation 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. This modification of parton-to-jet fragmentation and of the parton virtuality, induced by the QGP, can be studied using jet shapes, in particular using jet energy redistribution, intra-jet broadening or collimation. Results of a selected set of jet shapes are presented for p–Pb collisions at sNN=5.02 TeV and for Pb–Pb collisions at sNN=2.76 TeV . Results are also compared with PYTHIA Perugia 11 calculations and models that include in-medium energy loss.

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 $\sqrt{s_{\scriptscriptstyle \rm NN}}= 5.02~\mathrm{TeV}$ and for $\mbox{Pb--Pb}$ collisions at $\sqrt{s_{\scriptscriptstyle \rm NN}} = 2.76~\mathrm{TeV}$. Results are also compared with PYTHIA calculations and models that include in-medium energy loss.arXiv:1704.05230oai:cds.cern.ch:22603512017-04-18
