Description
The production of open heavy-flavour (charm and beauty) particles is one of the key observables in heavy-ion physics. Their large masses mean that they are produced at early times in the collision, and so precise measurements can help to probe the Quark-Gluon Plasma (QGP) that is expected to form in ultrarelativistic heavy-ion collisions. The observation of charmed baryons is of particular interest. A modification of the baryon-to-meson ratios has been observed for light-flavour particles, which can potentially be explained by quark coalescence and recombination models. Measurements of this quantity in the charm sector, and theoretical understanding of the results, will therefore shed further light on the hadronisation mechanisms present in the QGP. This talk will present recent measurements of charmed baryon production by the ALICE Collaboration at the LHC in pp, p-Pb and Pb-Pb collisions. In particular, the measurements of Λc baryons in all three collision systems will be shown, as well as the first measurements of Ξc production in pp collisions at the LHC.
