Abstract / Description of output
We report on a measurement of the Λ+c to D0 production ratio in peripheral
PbPb collisions at √sNN = 5.02 TeV with the LHCb detector in the forward rapidity regionv2 < y < 4.5. The Λ+c (D0) hadrons are reconstructed via the decay channel Λ+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 √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.
