The high collision energies available at the LHC allow for an abundant production of heavy quarks (charm and beauty), which are sensitive probes for investigating the properties of the Quark-Gluon Plasma (QGP) formed in high-energy heavy-ion collisions. Due to their large masses, they are produced in initial hard parton scattering processes on a timescale shorter than the QGP formation time and experience the whole system evolution. There have been extensive researches regarding the production of charm mesons, such as $\rm D^{0}$, $\rm D^{+}$, $\rm D^{*+}$, $\rm D^{+}_{s}$, in order to investigate the interactions of charm quarks with the QGP constituents and the transport properties of the medium. The measurement of charm-baryon production, and in particular the baryon-to-meson ratios, provides unique information on hadronisation mechanisms, constraining the role of coalescence and testing the predicted presence of diquark states in the QGP.

Measurements of charm-baryon production in pp collisions are important to set up a benchmark for Pb-Pb collisions and provide essential tests of pQCD calculations and models of charm hadronisation process. In this poster, the status and performance of the $\rm \Xi_{c}^{0}$ baryon measurements via the hadronic decay channel $\rm \Xi_{c}^{0} \rightarrow \pi^{+} \Xi^{-}$ (and its charge conjugate) in pp collisions at $\sqrt{s}=$ 13 TeV will be reported.
