We report on a measurement of the
Λ

$$ {\Lambda}_c^{+} $$
to D0 production ratio in peripheral PbPb collisions at
s
NN
$$ \sqrt{s_{\textrm{NN}}} $$
= 5.02 TeV with the LHCb detector in the forward rapidity region 2 < y < 4.5. The
Λ

$$ {\Lambda}_c^{+} $$
(D0) hadrons are reconstructed via the decay channel

$$ {\Lambda}_c^{+} $$
→ pK−π+ (D0 → K−π+) for 2 < pT < 8 GeV/c and in the centrality range of about 65–90%. The results show no significant dependence on pT, y or the mean number of participating nucleons. They are also consistent with similar measurements obtained by the LHCb collaboration in pPb and Pbp collisions at

$$ \sqrt{s_{\textrm{NN}}} $$
= 5.02 TeV. The data agree well with predictions from PYTHIA in pp collisions at
s
$$ \sqrt{s} $$
= 5 TeV but are in tension with predictions of the Statistical Hadronization model. |
