Аннотация

The production of Ξ_cc ⁺⁺ 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 Ξ_cc ⁺⁺ production cross-section times the branching fraction of the Ξ_cc ⁺⁺ → Λ_c ⁺ K^-π⁺ π⁺ decay relative to the prompt Λ_c ⁺ production cross-section is found to be (2.22 ± 0.27 ± 0.29) × 10^-4, assuming the central value of the measured Ξ_cc ⁺⁺ lifetime, where the first uncertainty is statistical and the second systematic.
