Résumé : The transverse momentum () spectra of inclusively produced baryons are measured via the exclusive decay channel using the CMS detector at the LHC. Spectra are measured as a function of transverse momentum in proton-proton () and lead-lead (PbPb) collisions at a nucleon-nucleon center-of-mass energy of 5.02 TeV. The measurement is performed within the rapidity interval in the range of 5–20 in and 10–20 in PbPb collisions. The observed yields of for of 10–20 suggest a suppression in central PbPb collisions compared to collisions scaled by the number of nucleon-nucleon (NN) interactions. The production ratio in collisions is compared to theoretical models. In PbPb collisions, this ratio is consistent with the result from collisions in their common range.
