Description
The ALICE detector at the Large Hadron Collider(LHC) is optimized for the studies of the Quark-Gluon Plasma (QGP) created in heavy-ion collisions. Charm quarks are one of the probes that is extensively used to elucidate the properties of the QGP. They are dominantly produced at the initial stage of the collisions via hard partonic scattering processes and experience the whole evolution of the system. Charm-baryon measurements provide unique insight into hadronisation precesses from the QGP. The baryon-to-meson ratio is expected to be enhanced if charm quarks hadronise via recombination with the surrounding 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 QGP. Thus, the measurements of charm baryons could shed light on an unexpected aspect of the QGP. Measurements of charm-baryon production in pp collisions are essential to establish a baseline for Pb–Pb collisions. In addition, the measurements in pp collisions provide critical tests of pQCD calculations and models of charm hadronisation in vacuum. In this talk, the pT differential cross section times branching ratio of the $\Xi^{0}_{c}$ baryon measured in the decay channel $\Xi^{0}_{c}\rightarrow e\Xi\nu$ in pp collisions will be reported.
