Abstract

We report on a measurement of the Λc+ to D0 production ratio in peripheral Pb Pb collisions at √s_NN = 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+ → p K− 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 p_T, y or the mean number of participating nucleons. They are also consistent with similar measurements obtained by the LHCb collaboration in p Pb and Pb p collisions at √s_NN = 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.
