  "abstract": "<p>The production of prompt ${\\Lambda }_{c}^{+}$ baryons at midrapidity ($|y|&lt;0.5$) was measured in central (0\u201310%) and mid-central (30\u201350%) Pb\u2013Pb collisions at the center-of-mass energy per nucleon\u2013nucleon pair $\\sqrt{{s}_{\\mathrm{NN}}}=5.02$ TeV with the ALICE detector. The results are more precise, more differential in centrality, and reach much lower transverse momentum (${p}_{T}=1$ GeV/c) with respect to previous measurements performed by the ALICE, STAR, and CMS Collaborations in nucleus\u2013nucleus collisions, allowing for an extrapolation down to ${p}_{T}=0$. The ${p}_{T}$-differential ${\\Lambda }_{c}^{+}/{D}^{0}$ ratio is enhanced with respect to the pp measurement for $4&lt;{p}_{T}&lt;8$ GeV/c by 3.7 standard deviations (\u03c3), while the ${p}_{T}$-integrated ratios are compatible within 1\u03c3. The observed trend is similar to that observed in the strange sector for the $\\Lambda /{K}_{S}^{0}$ ratio. Model calculations including coalescence or statistical hadronization for charm-hadron formation are compared with the data.</p>",
