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

Recent results of charmed baryon production in $pp$ collisions showed a significant enhancement of the baryon-to-meson ratio compared with the expectation based on $e^{+}{e}^{-}$ collisions. This indicates that the charm fragmentation into hadrons is not an universal process among different collision systems, and different mechanisms may play a role in the hadronic collisions with respect to $e^{+}{e}^{-}$ collisions. Therefore, the measurements of charmed baryon production are crucial to investigate the hadronisation mechanism of charm quarks. The production yield measurement of the ${\mathrm{\Xi }}_c^0$ baryon has been measured in $pp$ collisions at $\sqrt{s}=$ 5 and 13 TeV. Further studies of the multiplicity dependence of the baryon-to-meson yield ratios can provide more information on how the charm hadronisation processes evolve from small to large collision systems. Measurements in $p$-Pb collisions are important to separate the cold nuclear matter effects from the effects associated with the formation of quark-gluon plasma. In this contribution, the most recent measurements of the ${\mathrm{\Xi }}_c^0$ production via the semileptonic decay channel ${\mathrm{\Xi }}_c^0\to {\mathrm{\Xi }}^{-}{e}^{+}{\nu }_e$ in $pp$ collisions and the analysis status for the study of multiplicity dependence in $pp$ and $p$-Pb collisions will be shown.
