“…In order to make predictions for smaller systems size we hold all our parameters fixed based on the PbPb 5.02 TeV results, which have already been well-tested compared to experimental data [54]. Then the system size dependence arises through the initial conditions+hydrodynamical backgrounds calculated within Trento+v-USPhydro that were already discussed in detail in [55].…”

Recent experimental data at the Large Hadron Collider (LHC) confirmed that the soft sector azimuthal anisotropies in central XeXe collisions are sensitive to deformations in the wave function of the Xenon nucleus. Additionally, the CMS experiment found that D meson flow is slightly suppressed compared to other particle species when considering quark number scaling in small systems of pPb compared to PbPb. In this talk we used the D and B Mesons Modular (DAB-MOD) code coupled to Trento+v-USPhydro to calculate the R AA and v n 's of D mesons using different energy loss models and Langevin techniques. Comparing D mesons R AA and v n in PbPb to XeXe collisions it is found that in central collisions D meson azimuthal anisotropies are sensitive to details in the nuclear structure wave function of Xenon. Additionally, we find that in mid-central collisions the smaller system size of XeXe suppresses D meson flow. 13th International Workshop in High pT Physics in the RHIC and LHC Era (High-pT2019) 19

“…These observables have been studied in order to extract the heavy flavour transport coefficients and understand the HQs dynamics in QGP from a theoretical point of view [13][14][15][16][17][18][19][20][21][22][23]. Recently, further efforts have been done to extend the analysis to higher order anisotropic flows v n [24][25][26][27][28] that can provide more constraints on the extraction of the transport coefficients.…”

We study the production of charmed and multi-charmed hadrons in ultra-relativistic Heavy Ion Collisions coupling the transport approach for charm dynamics in the medium to an hybrid hadronization model of coalescence plus fragmentation. In this paper, we mainly discuss the particle yields for single charmed and multi-charmed baryons focusing mainly on the production of $$\Xi _{cc}$$ Ξ cc and $$\Omega _{ccc}$$ Ω ccc . We provide first predictions for PbPb collision in $$0 \! - \! 10\%\ $$ 0 - 10 % centrality class and then we explore the system size dependence through KrKr , to ArAr and OO collisions, planned within the ALICE3 experiment. In these cases, a monotonic behavior for the yields emerges which can be tested in future experimental data. We found about three order of magnitude increase in the production of $$\Omega _{ccc}$$ Ω ccc in PbPb collisions compared with the yield in small collision systems like OO collisions. Furthermore, we investigate the effects on the $$\Omega _{ccc}$$ Ω ccc particle yield and spectra coming from the modification of the charm quark distribution due to the different size of the collision systems also comparing it to the case of thermalized charm distributions. These results suggest that observation on the $$\Omega _{ccc}$$ Ω ccc spectra and their evolution across system size can give novel information about the partial thermalization of the charm quark distribution as well as to its wave function width. Furthermore, we find that the $$\Omega _{ccc}$$ Ω ccc /$$D^0$$ D 0 ratio is an observable more sensitive with respect to $$\Lambda _c$$ Λ c /$$D^0$$ D 0 , this ratio is predicted to span over two order of magnitude from large to small systems.
