Spectra are measured as a function of transverse momentum in proton-proton (pp) and lead-lead (PbPb) collisions at a nucleon-nucleon center-of-mass energy of 5.02 TeV. The measurement is performed within the Λc + rapidity interval |y|<1 in the pT range of 5–20GeV/c in pp and 10–20GeV/c in PbPb collisions. The observed yields of Λc + for pT of 10–20GeV/c suggest a suppression in central PbPb collisions compared to pp collisions scaled by the number of nucleon-nucleon (NN) interactions. The Λc +/D0 production ratio in pp collisions is compared to theoretical models. In PbPb collisions, this ratio is consistent with the result from pp collisions in their common pT range. © 2020 The Author(s)eninfo:eu-repo/semantics/openAccessCmsHeavy FlavorLambda(C) BaryonsNuclear Modification FactorPhysicsProduction of Λc + Baryons in Proton-Proton and Lead-Lead Collisions at S =5.02tevArticle2-s2.0-8508005426810.1016/j.physletb.2020.13532810.1016/j.physletb.2020.135328
