11th International Conference on Hard and Electromagnetic Probes of High-Energy Nuclear Collisions

In this contribution, we present the new measurements of non-prompt ${\mathrm{D}}^{+}$ and ${\mathrm{D}}_{\mathrm{s}}$ in pp collisions at $\sqrt{s}$ = 13 TeV. Together with the final measurements of non-prompt ${\mathrm{D}}^0$ and ${\mathrm{\Lambda }}_{\mathrm{c}}^{+}$, they are crucial to study the beauty quark hadronisation in proton-proton (pp) collisions and their difference with respect to ${\mathrm{e}}^{+}{\mathrm{e}}^{-}$ collisions. In addition, the baryon-to-meson ratio in pp collisions compared with that in ${\mathrm{e}}^{+}{\mathrm{e}}^{-}$ and electron--proton collisions and model predictions, and the measurements of charm fragmentation fraction in pp and pPb collision will be reported as well.

Furthermore, the new non-prompt ${\mathrm{\Lambda }}_{\mathrm{c}}^{+}/{\mathrm{D}}^0$ ratio in p-Pb collisions as well as the first measurement of non-prompt ${\mathrm{D}}^0$ nuclear modification factor $R_{\mathrm{pPb}}$ at $\sqrt{s_{\mathrm{NN}}}=5.02$ TeV will be presented. The status of prompt ${\mathrm{\Xi }}_{\mathrm{c}}$ $R_{\mathrm{pPb}}$ studies will be reported. They provide important information about Cold-Nuclear Matter (CNM) effects and to understand how the possible presence of collective effects could modify the production of heavy-flavour hadrons and the similarities observed among pp, p-nucleus, and nucleus--nucleus systems.
