Open heavy flavor transport and hadronization in heavy-ion collisons*

Heavy quarks serve as a clean probe of the quark-gluon plasma (QGP) matter produced in high-energy nuclear collisions, as they are primarily produced from early-state hard scatterings and encode information about the entire evolution history of the QGP fireballs. We study the space-time evolution of open heavy flavor in heavy-ion collisions using our modular state-of-the-art model, which comprehensively describes different stages of heavy-ion collisions. Utilizing the heavy quark transport coefficient calculated from the T-matrix approach, we focus on the heavy quark Langevin dynamics in the QGP. Both fragmentation and recombination effects are considered during the heavy quark hadronization processes. We calculated the typical observables of open heavy flavor physics: nuclear modification factor, elliptic flow, and baryon-to-meson ratio. Our results accurately describe the Pb-Pb collision experimental data from ALICE.
