Heavy flavour hadronization from AA to pp collisions

One of the current challenges in understanding heavy-quark hadronization lies in interpreting measurements of heavy baryon production across various collision systems like AA, pA, and pp collisions. Predictions based on coalescence and fragmentation hadronization approaches have shown a baryon/meson ratio Λc/D0 on the order of unity in AA collisions. This was initially observed at RHIC energies and more recently in pp, pA, and AA collisions at the LHC energies. The ratio in smaller collision systems suggests a significant departure from that observed in elementary collision systems, where the Λc/D0 ratio is typically on the order of 10−1. We present an hadronization mechanism based on the coalescence and fragmentation processes. We show that within this model it is possible describe several observables involving heavy-flavour hadrons from AA collision to pp collisions. The results suggest that a description of charmed hadron production in smaller systems like in pp collisions require the assumption of an hot QCD medium. Furthermore, we will explore particle yields of multi-charmed baryons like Ξcc,Ωcc and Ωccc. Finally, we discuss the charmed and multi-charmed hadrons production in PbPb collisions within the 0−10% centrality class and furthermore we show the predictions of multi-charmed hadrons in different collision systems like Pb+ Pb, Kr+Kr, Ar+Ar and O+O.
