# $\Xi^{0}_{c}$ production in semi-leptonic decay channel in pp collisions at 5 TeV

The ALICE detector at the Large Hadron Collider (LHC) is optimised for the investigation of the Quark-Gluon Plasma (QGP) created in heavy-ion collisons. Charm quarks are effective probes to elucidate the properties of the QGP. They are dominantly produced at the initial stage of the collisons via hard partonic scattering processes and experience the whole evolution of the system.

Charm-baryon measurements provides unique insight into hadronisation prcesses. In particular, the baryon-to-meson ratio is expected to be enhanced if charm quarks hadronise via recombination with the surroudning light quarks in the QGP. Moreover, in such a recombination picture, the baryon-to-meson ratio could further be enhanced in the presence of diquark bound states in the hot and dense QCD medium. Measurements of charm-baryon production in pp collisions are essebtial to establish a baseline for studies in Pb-Pb collisions. In addition, the measuremnt in pp collisons provide critical tests of pQCD calculations and for models of charm hadronisation in vacuum.

In this paper, the $p_{\rm T}$ differential cross section of the $\Xi^{0}_{\rm c}$ baryon measured in the decay channel $\Xi^{0}_{\rm c} \rightarrow e\Xi\nu$ in pp collisions at $\sqrt s = 5.02$ TeV will be shown.
