    <description descriptionType="Abstract">&lt;p&gt;The production of prompt ${\Lambda }_{c}^{+}$ baryons at midrapidity ($|y|&amp;lt;0.5$) was measured in central (0–10%) and mid-central (30–50%) Pb–Pb collisions at the center-of-mass energy per nucleon–nucleon 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–nucleus 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 $4&amp;lt;{p}_{T}&amp;lt;8$ GeV/c by 3.7 standard deviations (σ), while the ${p}_{T}$-integrated ratios are compatible within 1σ. 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.&lt;/p&gt;</description>
