### Description

The ALICE (A Large Ion Collider Experiment) experiment at CERN is mainly aimed to study strongly-interacting matter under extreme conditions of temperature and energy density and, in particular, to verify the QCD predictions about the existence of a phase transition of the hadronic matter to the Quark-Gluon Plasma (QGP).
Heavy quarks (charm and beauty) are a powerful tool to study the properties of the QGP. Indeed they are formed during the early stages of the collisions via hard scattering of high-energy partons, on a time scale generally shorter than the QGP thermalisation time. So they can traverse the QCD medium, interact with its constituents and experience the whole evolution of the medium.
The $\Lambda_{c}^{+}$\$\rm D^{0}$ ratio is sensitive to hadronisation mechanisms and it will offer a unique probe of the role of coalescence and predicted existence of diquark states in the QGP.
Measurements of charmed-baryon production in small system (pp and p-Pb) collisions are a fundamental reference for measurements in Pb-Pb collisions and allow studies of possible modifications of the production due to cold nuclear matter effects.
Moreover, the study of charm production as a function of the multiplicity of charged particles produced in the collision can give insight into multi-parton interactions and into the interplay between hard and soft processes.
The recent results for $\Lambda_{c}^{+}$ baryons reconstructed via their hadronic decay $\Lambda_{\rm c}^{+}\to p \rm K^{0}_{\rm S}$ at mid-rapidity in p-Pb collisions at $\sqrt{s_{NN}}$ = 5.02 TeV will be presented.
The analysis takes advantage of the high precision tracking, good vertexing capabilities and excellent particle identification offered by the ALICE detector.
