Investigating charm-quark dynamics in the QGP via the charm-hadron elliptic flow in Pb–Pb collisions with ALICE

In these proceedings, we report the measurement of the elliptic flow ( v 2 ) of prompt and non-prompt D 0 , prompt D + and D s + mesons, and, for the first time ever at the LHC, prompt and non-prompt Λ c + baryons in Pb-Pb collisions at √ s NN = 5.36 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 D 0 ,D + , and D s + ; 30–50% for Λ c + ). The candidates are reconstructed from hadronic decay channels, and the v 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.
