The role of strangeness and baryon enhancement in heavy-quark hadronisation from pp to Pb$-$Pb collisions with ALICE

Abstract

In this contribution, a combined study of charm-meson and charm-baryon production with ALICE is presented. The ${\Lambda }_{\mathrm{c}}^{+}/{\mathrm{D}}^0$ ratio in pp collisions at $\sqrt{s}=13.6$ TeV and the first measurement of the nuclear modification factor of ${\Xi }_{\mathrm{c}}^0$ baryons in Pb$-$Pb collisions at $\sqrt{s_{\mathrm{NN}}}=5.02$ TeV are reported. Furthermore, measurements of the ${\mathrm{D}}_{\mathrm{s}}^{+}/{\mathrm{D}}^{+}$ production ratio from low-multiplicity pp collisions at $\sqrt{s}=13.6$ TeV to Pb$-$Pb collisions at $\sqrt{s_{\mathrm{NN}}}=5.36$ TeV are presented. Lastly, the first measurement of the $p_{\mathrm{T}}$-differential ${\mathrm{D}}_{s1}(2536{)}^{+}/{\mathrm{D}}_{\mathrm{s}}^{+}$ yield ratio is shown.
