 | Transverse-momentum differential yields of charm jets tagged with prompt \Dzero mesons in central (0--10\%) Pb--Pb collisions at \snn\ = 5.02~TeV (red markers) and cross section in pp collisions at \s\ = 5.02~TeV (blue markers) scaled by the nuclear overlap function $\left \langle T_\mathrm{AA} \right \rangle$ for the considered centrality interval. The vertical lines are the statistical uncertainties and the filled squares are the systematic uncertainties. |
 | Nuclear modification factor of \Dzero jets (red markers), inclusive jets with resolution parameter $R=0.2$ (light blue) and $R=0.4$ (blue markers)~\cite{ALICE:2023waz}, and averaged \Dzero, D$^{+}$, D$^{*+}$ mesons~\cite{ALICE:2021rxa} (green markers). Statistical and systematic uncertainties are shown as vertical error bars and boxes, respectively. The global uncertainty originated from the $\left \langle T_\mathrm{AA} \right \rangle$ normalisation and the luminosity is displayed as a box around unity. |
 | Transverse momentum distributions of \Dzero mesons (green markers)~\cite{ALICE:2019nxm}, inclusive jets with jet resolution parameter 0.2 (light blue) and 0.4 (blue markers)~\cite{ALICE:2019wqv}, and \Dzero jets (red markers) in pp collisions at $\sqrt{s} = 5.02$ TeV (see text for details about the normalisation). Statistical and systematic uncertainties are shown as vertical error bars and boxes, respectively. The function $\alpha/p_{\rm{T}}^{\rm{\beta}}$ was fitted to each of the distributions (solid lines) to compare their steepness. |
 | Left: comparison of the nuclear modification factor of \Dzero jets (and inclusive jets) with predictions from JETSCAPE~\cite{Putschke:2019yrg} and Dai et al.~\cite{Dai:2018mhw}. The bands of the theory curves represent the systematic uncertainties on the model predictions. Right: comparison to the LIDO~\cite{Ke:2018jem, Ke:2018tsh} predictions for \Dzero jets with and without dead-cone effect and predictions for inclusive jets. |
