We report on a measurement of the Λ+c to D0 production ratio in peripheral PbPb collisions at √ sNN = 5.02TeV with the LHCb detector in the forward rapidity region 2 < 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 = 5.02TeV. The data agree well with predictions from PYTHIA in pp collisions at √ s = 5TeV but are in tension with predictions of the Statistical Hadronization model.

Abstract
We report on a measurement of the Λ+c to D0 production ratio in peripheral PbPb collisions at √ sNN = 5.02TeV with the LHCb detector in the forward rapidity region 2 < 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 = 5.02TeV. The data agree well with predictions from PYTHIA in pp collisions at √ s = 5TeV but are in tension with predictions of the Statistical Hadronization model.File | Dimensione | Formato | |
