Beschreibung
In this contribution, we present the new measurements of non-prompt $\mathrm{D}^+$ and $\mathrm{D_s}$ in pp collisions at $\sqrt{s}$ = 13 TeV. Together with the final measurements of non-prompt $\mathrm{D}^0$ and $\Lambda_\mathrm{c}^+$, they are crucial to study the beauty quark hadronisation in proton-proton (pp) collisions and their difference with respect to $\mathrm{e^+e^-}$ collisions. In addition, the baryon-to-meson ratio in pp collisions compared with that in $\mathrm{e^+e^-}$ 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 $\Lambda_\mathrm{c}^+/\mathrm{D}^0$ 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 $\Xi_\mathrm{c}$ $R_\mathrm{pPb}$ 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.
