The $\\Lambda_{\\rm {c}}^{+}$ and $\\Lambda_{\\rm {c}}^{-}$ were reconstructed at midrapidity ($|y| &lt; 0.5$) via the hadronic decay channel $\\Lambda_{\\rm {c}}^{+} \\to {\\rm {p}} {\\rm {K}}^{0}_{\\rm {S}}$ (and charge conjugate) in the transverse momentum and centrality intervals 6 &lt; $p_{\\rm {T}}$ &lt;12 GeV/${\\it {c}}$ and 0-80%. The $\\Lambda_{\\rm {c}}^{+}$/${\\rm D}^{0}$ ratio, which is sensitive to the charm quark hadronisation mechanisms in the medium, is measured and found to be larger than the ratio measured in minimum-bias pp collisions at $\\sqrt{s} = 7$ TeV and in p-Pb collisions at $\\sqrt{s_{\\rm {NN}}} = 5.02$ TeV. In particular, the values in p-Pb and Pb-Pb collisions differ by about two standard deviations of the combined statistical and systematic uncertainties. The $\\Lambda_{\\rm {c}}^{+}$/${\\rm D}^{0}$ ratio is also compared with model calculations including different implementations of charm quark hadronisation. The measured ratio is reproduced by models implementing a pure coalescence scenario, while adding a fragmentation contribution leads to an underestimation. The $\\Lambda_{\\rm {c}}^{+}$ nuclear modification factor, $R_\\mathrm{AA}$, is also presented. The measured values of the $R_\\mathrm{AA}$ of $\\Lambda_{\\rm {c}}^{+}$, ${\\rm D}_{\\rm {s}}$ and non-strange D mesons are compatible within the combined statistical and systematic uncertainties. They show, however, a hint of a hierarchy $R_\\mathrm{AA}^{{\\rm D}^{0}}&lt;R_\\mathrm{AA}^{{\\rm D}_{\\rm {s}}}&lt;R_\\mathrm{AA}^{\\Lambda_{\\rm {c}}^{+}}$, conceivable with a contribution of recombination mechanisms to charm hadron formation in the medium.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.89397.v1/t1","@type":"Dataset","description":"$\\Lambda_{\\rm {c}}^{+}$/${\\rm D}^{0}$ ratio in 0-80% most central Pb-Pb collisions at $\\sqrt{s_{\\rm {NN}}} = 5.02$ TeV in the transverse momentum...","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.89397.v1/t2","@type":"Dataset","description":"The nuclear modification factor $R_\\mathrm{AA}$ of prompt $\\Lambda_{\\rm {c}}^{+}$ baryons in 0-80% most central Pb-Pb collisions at $\\sqrt{s_{\\rm {NN}}} =...","name":"Table 2"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1696315?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/89397"}],"inLanguage":"en","name":"$\\Lambda_\\mathrm{c}^+$ production in Pb-Pb collisions at $\\sqrt{s_{\\rm NN}} = 5.02$ TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1696315?version=1","version":1}
