Abstract

In these proceedings, we report the measurement of the elliptic flow (v₂) of prompt and non-prompt D⁰, 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 D⁰,D⁺, and D_s⁺; 30–50% for Λ_c⁺). The candidates are reconstructed from hadronic decay channels, and the v₂ 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.
