Abstract: The production of prompt $\rm \Lambda_{\rm c}^{+}$ baryons at midrapidity ($|y|<0.5$) 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 $\rm \Lambda_{\rm c}^{+}$ production yield, the $\rm \Lambda_{\rm c}^{+} / D^0$ production ratio, and the $\rm \Lambda_{\rm c}^{+}$ nuclear modification factor $R_{\rm AA}$ are reported. The results are more precise and more differential in transverse momentum ($p_{\rm T}$) and centrality with respect to previous measurements. The $\rm \Lambda_{\rm c}^{+} / D^0$ ratio, which is enhanced with respect to the pp measurement for $4<p_{\rm T}<8$ GeV/$c$, is described by theoretical calculations that model the charm-quark transport in the quark--gluon plasma and include hadronization via both coalescence and fragmentation mechanisms.
