Abstract: The transverse momentum (pT) spectra of inclusively produced ?c+ baryons are measured via the exclusive decay channel ?c+?pK??+ using the CMS detector at the LHC. 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 ?c+ 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 ?c+ 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 ?c+/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.
