Investigation of charm-quark fragmentation by correlation and jet measurements with ALICE

Abstract

Measurements of heavy-flavour tagged jets, allow for comparisons of the heavy quarks (charm and beauty) production, propagation, and hadronization across different collision systems. Comparison of measurements performed in pp with Pb--Pb collisions can help in studying the possible modification of the heavy-quark production and hadronization inside jets due to the quark-gluon plasma medium. This article presents the ALICE measurements of jets tagged with D-mesons in pp collisions at $\sqrt{s}=5.02$ TeV and $\sqrt{s}=13$ TeV (including the observation of dead-cone effect), as well as in Pb--Pb collisions at $\sqrt{s_{\mathrm{NN}}}=5.02$ TeV.
