Abstract

In this contribution, the latest results for measurements of charm baryons in proton--proton collisions at s=5.02\sqrt{s}=5.02 and 13TeV13\,\mathrm{TeV} are presented. The production yields of Λc+\Lambda_\mathrm{c}^{+}, Ξc0,+\Xi_\mathrm{c}^{0,+}, Ωc0\Omega_\mathrm{c}^{0}, and Σc0,++\Sigma_\mathrm{c}^{0,++} are shown along with their yield ratios to D0\mathrm{D}^{0} mesons, and observations about charm hadronisation with respect to previous results from lepton colliders are discussed. Further differential measurements are shown of the Λc+/D0\Lambda_\mathrm{c}^{+}/\mathrm{D}^{0} yield ratio as a function of charged-particle multiplicity. For the first time, the production of Λc+\Lambda_\mathrm{c}^{+} is presented in pp collisions down to pT=0p_\mathrm{T} = 0, and the total charm production cross section and relative charm hadronisation fractions in p--Pb collisions are computed.
