Description
Measurements of charm-strange meson and charm-baryon production in pp and heavy-ion collisions at the LHC are fundamental to investigate the charm-quark hadronisation across collision systems.
In this contribution, the final results of the ALICE Collaboration on the production of strange ($\mathrm{D_s}^+$ , $\Xi_\mathrm{c}^{0,+}$, $\Omega_\mathrm{c}^0$) and non-strange ($\mathrm{D}^0$ , $\mathrm{D}^+$, $\mathrm{D}^{*+}$ , $\Lambda_\mathrm{c}^+$, $\Sigma_\mathrm{c}^{0,+,++}$) charm hadrons in pp, p–Pb and Pb–Pb collisions collected in Run 2 by the ALICE experiment are shown. The production measurements of $\mathrm{D_s}^+$ mesons are compared to those of non-strange mesons, and the comparison between the measured baryon-to-meson ratios with novel theoretical calculations will be discussed. To conclude, the first studies of charm-hadron reconstruction using the large data sample of pp collisions at $\sqrt s $= 13.6 TeV harvested from the start of LHC Run 3 are presented.
