      abstract     = {A measurement of the production of prompt
                      $\Lambda_\mathrm{c}^+$ baryons in Pb–Pb collisions at
                      $\sqrt{s_{\rm NN}}$ = 5.02 TeV with the ALICE detector at
                      the LHC is reported. The $\Lambda_\mathrm{c}^+$ and
                      $\bar{\Lambda_\mathrm{c}}^-$ were reconstructed at
                      midrapidity (|y|<0.5) via the hadronic decay channel
                      $\Lambda_\mathrm{c}^+$→pK$_{\rm S}^0$ (and charge
                      conjugate) in the transverse momentum and centrality
                      intervals 6 < $p_{\rm T}$ < 12 GeV/ c and 0–80\%. The
                      $\Lambda_\mathrm{c}^+$/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 in the common
                      $p_{\rm T}$ interval covered by the measurements in the two
                      collision systems. The $\Lambda_\mathrm{c}^+$/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
                      $\Lambda_\mathrm{c}^+$ nuclear modification factor, $R_{\rm
                      AA}$, is also presented. The measured values of the $R_{\rm
                      AA}$ of $\Lambda_\mathrm{c}^+$, 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 ($R_{\rm AA}^{D^0}$ < $R_{\rm
                      AA}^{D_\mathrm{s}^+}$ < $R_{\rm AA}^{\Lambda_\mathrm{c}^+}$)
                      , conceivable with a contribution from coalescence
                      mechanisms to charm hadron formation in the medium.},
