Description
Charm quarks serve as a sensitive probe of the Quark Gluon Plasma providing direct insights into its formation, evolution, and properties. We present the first-ever measurement of the elliptic flow of charm baryons, specifically prompt $\Lambda_c^+$, in lead-lead (PbPb) collisions at a center-of-mass energy of 5.36 TeV, using the CMS experiment. We also present the elliptic and triangular flow of prompt $D_{s}^{\pm}$ mesons with new standard of precision. The broader kinematic coverage and the first-ever $v_3$ measurement of $D_{s}^{\pm}$ mesons provide new insights into charm quark flow generation mechanisms and the impact of hadronization on flow. By comparing the flow of prompt $\Lambda_c^+$ and prompt $D_{s}^{\pm}$ to $D^0$ mesons in the same kinematic range, we investigate charm quark interactions with the medium and hadronization mechanisms. Additionally, we explore the charm quark hadronization mechanism further by measuring the $\Lambda_c^+/D^0$ yield ratio across pp, PbPb, and pPb collisions. These results offer a unique opportunity to explore the influence of initial-state effects on heavy quark dynamics. Additionally, comparison with theoretical models provides critical validation of the underlying physics mechanisms, and provide deeper insights into charm quark dynamics in heavy ion collisions.
