Abstract
The Λc/D0 ratio observed in AA collisions at RHIC and LHC energies have a value of the order of the unity. On the other hand, the recent experimental measurements in pp collisions at both √s = 5.02 TeV and √s = 13 TeV have shown ratios for charm baryons/mesons Λc/D0 and Ξc/D0 larger than those measured and expected in elementary e+e− collisions. We present a hadronization mechanism based on the coalescence and fragmentation processes and we show that this model gives a consistent description of several observables involving heavy flavour hadrons from AA collisions to pp collisions. The results obtained within this approach suggest that a description of charmed hadron production in pp collisions require the assumption of the formation of a hot QCD matter at finite temperature. Finally, extending this approach to study the production of hadrons containing multiple charm quarks, Ξcc, Ωcc and Ωccc we provide the predictions of multi-charmed hadrons in different collision systems, like Pb+Pb, Kr+Kr, Ar+Ar and O+O.
