Investigating charm-quark dynamics in the QGP via the charm-hadron elliptic flow in $\rm{Pb-Pb}$ collisions with ALICE

Abstract

In these proceedings, we report the measurement of the elliptic flow ($v_{\rm 2}$) of prompt and non-prompt $\mathrm{D^0}$, prompt $\mathrm{D^+}$ and $\mathrm{D_s^+}$ mesons, and, for the first time ever at the LHC, prompt and non-prompt $\Lambda_\mathrm{c}^+$ baryons in \PbPb collisions at $\sqrt{s_{\mathrm{NN}}} = 5.36\ \mathrm{TeV}$ collected by the ALICE experiment during the LHC Run 3. The analysis is performed at midrapidity ($|y| < 0.8$) in different centrality classes ($30-40\%$, $40-50\%$, and $60-80\%$ for $\mathrm{D^0}$, $\mathrm{D^+}$, and $\mathrm{D_s^+}$; $30-50\%$ for $\Lambda_\mathrm{c}^+$). The candidates are reconstructed from hadronic decay channels, and the $v_{\rm 2}$ is extracted via the scalar-product method. The measurements are compared to light-flavor results and several predictions of models that differently describe heavy-quark transport and hadronization processes in the QGP.
