Abstract

We report on a measurement of the Λc+ to D0 production ratio in peripheral PbPb collisions at √sNN = 5.02 TeV with the LHCb detector in the forward rapidity region 2 < y < 4.5. The Λc+ (D0) hadrons are reconstructed via the decay channel Λc+ → pK−π+ (D0 → K−π+) for 2 < p T < 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 √sNN = 5.02 TeV. The data agree well with predictions from PYTHIA in pp collisions at s = 5 TeV but are in tension with predictions of the Statistical Hadronization model.
