Investigating charm quark interactions and hadronization in PbPb collisions with D

Charm quarks serve as a sensitive probe of the Quark-Gluon Plasma (QGP), providing direct insights into its formation, evolution, and properties. In this proceeding, we present new high-precision measurements from the CMS experiment in Pb-Pb collisions at √sNN = 5.02 TeV. The elliptic (v2 ) and triangular (v3) flow of prompt Ds± mesons are measured with high precision, extending the kinematic coverage. A comparison of the Ds± flow to that of D0 mesons is performed to investigate the impact of strange quark hadronization on charm quark collectivity. We further explore charm quark hadronization by measuring the Λc±/D0 nuclear modification factor (RAA) as a function of transverse momentum for different collision centralities, and the Λc±/D0 yield ratio in pp, pPb, and Pb-Pb collisions. These results provide crucial constraints on charm quark energy loss and hadronization mechanisms, offering critical tests for theoretical models and advancing our understanding of heavy quark dynamics in the QGP
