Description

We present a comprehensive analysis of heavy-flavor transport and hadronization in ultra-relativistic heavy-ion collisions. An updated version of the Quasi-Particle Model (QPM), denoted QPM$_p$, is introduced byincluding momentum-dependent parton masses consistent with QCD asymptotic freedom. This extensionimproves the agreement with lattice QCD calculations of quark susceptibilities. Within an event-by-eventtransport framework based on Langevin dynamics, we compute the main heavy flavour observable likenuclear modification factor $R_{AA}(p_T)$ and the anisotropic flow coefficients $v_n(p_T)$ for $D$mesons, achieving good agreement with current experimental data. We emphasize the critical role ofmomentum-dependent interactions in reproducing key observables and ensuring consistency with recentlattice QCD results. Finally, we investigate the enhancement of heavy baryon production using ahadronization scheme that combines recombination and fragmentation. This model successfully reproducesthe $\Lambda_c/D^0$, $\Xi_c/D^0$, and $\Omega_c/D^0$ ratios across pp, pA, and AA systems.Predictions are also extended to multi-charmed and bottom baryons over a broad range of system sizes.
