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

Year: 2026

Type: article

Abstract: In these proceedings, we report the measurement of the elliptic flow (v2) of prompt and non-prompt D0, prompt D+ and Ds+ mesons, and, for the first time ever at the LHC, prompt and non-prompt Λc+ baryons in Pb-Pb collisions at √sNN = 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 Ds+; 30–50% for Λc+). 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.
