Production of Λ+c baryons in proton-proton and lead-lead collisions at √snn = 5.02 TeV

The transverse momentum (pT) spectra of inclusively produced Λ+c baryons are measured via the exclusive decay channel Λ+c pK ¯π+ 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 cen...
