Abstract

The production of Ξcc ++ baryons in proton-proton collisions at a centre-of-mass energy of √s = 13TeV is measured in the transverse-momentum range 4 < PT < 15 GeV/c and the rapidity range 2.0 < y < 4.5. The data used in this measurement correspond to an integrated luminosity of 1.7 fb-1, recorded by the LHCb experiment during 2016. The ratio of the Ξcc ++ production cross-section times the branching fraction of the Ξcc ++ → Λc + K-π+ π+ decay relative to the prompt Λc + production cross-section is found to be (2.22 ± 0.27 ± 0.29) × 10-4, assuming the central value of the measured Ξcc ++ lifetime, where the first uncertainty is statistical and the second systematic.
